Melitea Maria, n. sp.—Male: Expands 1½ inches. Upper side. Primaries. The outer margin of the wing has along its edge about eight brick-red spots; internal to these is another row of yellow spots, separated from the former by a very small space. Next comes a row of yellow spots, the first four having an outward curve, and the lower three an inward curve. There then comes a row of quadrate brick-red spots, nearly parallel to the preceding yellow row. At the end of the cell are three yellow quadrate spots. The cell has in it two comparatively large red spots, outlined with black, and having a yellow patch between them and another toward the base. There is also a quadrate yellow spot with concave sides in the space below the third median nerve. The secondaries are marked in a similar manner.

During his study of the ecology of red pine plantations, Mr. J. L. Martin, Forest Insect Laboratory, Sault Ste. Marie, Ontario, found a species of Laspeyresia feeding as larvae under the bark of living trees. This species is described here to enable him to report on the results of his investigation.Laspeyresia resinosae, new speciesAntenna, head, thorax, and abdomen powdery-grey. Basal half of forewing grey; outer half blackish, with cupreous reflections, the tips of the scales ochreous; outer three-fifths of costa with four pairs of silvery-white geminations; the basal pair of geminations fuse into a single, angular, transverse, shiny-leaden fascia, that extends to the trailing margin just beyond the middle; a similar fascia arises from the second costal geminations, and extends only to the fold; a third leaden fascia arises from the apical geminations, extends irregularly to the tornus, and is broken into three almost equal sections; the central portions of the second and third fasciae are narrowly margined with a few black scales, representing a very poorly defined ocelloid patch; outer margin with a very distinct black line basad to the shiny leaden fringe; the black line cut by three white dashes, two opposite the breaks in the outer, transverse fascia, and the third at the tornal end of that fascia. Hind wing powdery-grey; fringe dirty-white with darker basal line. Under-surface and legs silvery-grey. Tarsi black banded. Wingspread: 9.5-10.5 mm. Moth in late June and early July.

The communications between the median and ulnar innervated territories on the palm of the hand have been studied anatomically and microscopically. A communicating branch is well appreciated but its description has had little emphasis in anatomical or surgical literature. 50 cadaveric palms were dissected in both sexes and an anastomotic branch was found in 45 hands. In 43 of them it originated proximally from the ulnar nerve and proceeded distally to enter the third common digital nerve; in the other two hands it left the median nerve to reach the fourth common digital nerve. By microscopic dissection we have seen that the ulnar fibres of the anastomotic branch which join the median nerve may contribute to the sensory innervation of the radial half of the ring finger and ulnar side of the middle finger on its palmar surface. We have therefore described a cutaneous area on the palm where care must be taken to avoid surgical damage to this branch.

The biceps brachii is one of three muscles of the anterior compartment of arm. Variations of the biceps brachii are not rare. The most frequent is the existence of a third head called the humeral head by Le Double (1897) (Rodríguez-Vázquez et al., 1999). Our article is based on the unexpected result of a routine dissection class held for medical students. Dissection was performed according to the guidelines accepted by the anatomy department (Seichert, 1999). We describe a third (accessory) head of the biceps brachii. In addition of two regular heads, the third head originated together with the short head from the coracoid process and had three insertions on the humerus after enfolding the median nerve and the brachial artery. This particular variation is important from a clinical perspective as the third head may cause entrapment syndrome of the median nerve and hypoperfusion of the upper limb due to compression of the brachial artery.

AbstractThe Coracobrachialis muscle in the arm is more important morphologically than functionally. In many animals, the Coracobrachialis has three parts. During the process of evolution the third part has disappeared and only the first two parts are found in man, enclosing the musculocutaneous nerve between them. Morphologic variations of Coracobrachialis have been known for a long time and include accessory slips that attach to the lesser tubercle, medial supracondylar ridge and medial intermuscular septum. The existence of abnormal insertion of the corabrachialis muscle should be kept in mind in a patient presenting with high median nerve palsy together with symptoms of brachial artery compression and before carrying out post-mastectomy reconstruction using coracobrachialis as a transposition flap.

CONTEXT: The musculocutaneous nerve is one of the terminal branches of the lateral fasciculus of the brachial plexus, and is responsible for innervation of the flexor musculature of the elbow and for skin sensitivity on the lateral surface of the forearm. Its absence has been described previously, but its real prevalence is unknown. CASE REPORT: A case of absence of the musculocutaneous nerve that was observed during the dissection of the right arm of a male cadaver is described. The area of innervation was supplied by the median nerve. From this, three branches emerged: one to the coracobrachialis muscle, another to the biceps brachii muscle and the third to the brachialis muscle. This last branch continued as a lateral antebrachial cutaneous nerve. This is an anatomical variation that has clinical-surgical implications, considering that injury to the median nerve in this case would have caused unexpected paralysis of the flexor musculature of the elbow and hypoesthesia of the lateral surface of the forearm.

It has long been recognized that the first and second lumbricals are normally innervated by the median nerve, whereas the third and fourth lumbricals are innervated by the ulnar nerve (Sunderland and Ray, 1946). However, the courses of the motor nerves, particularly to the first two lumbricals and their loci of insertion, have not been clearly described. Because this information may be useful to a surgeon operating in the palm, we undertook a cadaver study to define more precisely the pathways of innervation of the lumbrical muscles.

Mesothorax all black, except a small yellow spot on each side at hind border, adjacent to yellow spot of scutellum. Scutellum with a pair of large yellow spots. Postscutellum yellow. Inner side of anterior half of anterior femora yellow. Tibiæ yellow, with more or less black behind. Tarsi yellow, slightly tending to orange. Segments 1-6 of abdomen presenting a yellow spot medially, and a large yellow patch on each side. The median spot on first segment is round, that on 2-3 transversely oval, that on 4 transversely spindle shaped, that on 5 broad with truncate ends, that on 6 nearly square, but slightly constricted on each side. Lateral patches more or less bifid at their inner ends, and produced to a point below on lateral margin of abdomen. Strongly punctured, much more sparsely on pleura. Pubescence of face and cheeks silvery. Eyes very large, at least as near together on middle of face as the two upper ocelli are to one another.
