A new record of the fossil genus Elasmosomites Brues, 1933 from Baltic amber with an illustrated description of a new species, E. arkadylelejisp. nov. and the first description of a male of E. primordialis Brues, 1933 are provided. A key to currently known Neoneurini genera is compiled. A new record of fossil braconid larva emerging from an ant worker of Lasius schiefferdeckeri Mayr, 1868 is discussed and a correction to previous determination of ant hosts from amber is included.

At the November (1923) meeting of the Society I gave an account of a new find of euclase of peculiar habit and of native platinum from the gold and diamond washings in British Guiana. The occurrence of platinum being a new record for that country, the announcement was naturally received there with some interest—but also with some scepticism. Mr. J. C. Menzies, by whom the platinum was found, has been accused of ‘salting’ the locality, or, alternatively, doubt has been cast on the correctness of my determination. The euclase aggregates, thought by Mr. Menzies to be fossils, could certainly not have been used by him for ‘salting’; and as the platinum (together with some small, silvery scales of mica) came with these, I have no reason to doubt his bona tides. I am also quite satisfied with the correctness of my determination of the material as platinum, as set out in detail on p. 191 of this volume.

A study was carried out in Kahramanmaras region of Turkey during 2012-13 having ten subregions namely, Afsin, And?r?n, Caglayancerit, Ekinozu, Elbistan, Göksun, Center, Nurhak, Pazarc?k and Türkoglu to determine the range, density and frequency of weeds in apple orchards. In the orchards 133 weed species from 31 families were determined. The average density of weeds was 112.49 plants m-2. The maximum density of weed species was found in Göksun (127.30 plants m-2) followed by Elbistan (126.13 plants m-2), Ekinozu (125.95 plants m- 2), Afsin (120.39 plants m-2), Center (117.94 plants m-2) and Caglayancerit (114.90 plants m-2), and the minimurn density was determined in Pazarc?k (69.51 plants m-2). From the identified 133 weed species one species belonged to Pterydophyta, 2l species to Monocotyledoneae and 111 species to Dicotyledoneae. The average densities of the weed species over l0 subregions for Agropyron repens (L.) P. Beauv., Chenopodium album L., Bromus arvensis L. and Amaranthus retroflexus L. were found to be 13.76, 12.17, 12.10 and 10.76 plants m-2, respectively. With regard to frequency of occurrence, C. album L. was detected more than 56% in six subregions excluding And?r?n, Pazarc?k, Türkoglu and Center; A. retroflexus L. more than 54% in 7 subregions excluding Center, Pazarc?k and Türkoglu and A. repens (L.) P. Beauv. more than 50% in 10 subregions. Frequency of occurance of Cynodon dactylon (L.) Pers. was observed 50.1, 50.9, 76.9% in Afsin, Caglayancerit and And?r?n, respectively and it was below 50% in other 7 subregions. In terms of coverage, Alopecurus myosuroides Huds., A. retroflexus, A. repens, B. arvensis, C. album, Convolvulus arvensis L., C. dactylon and Lactuca serriola L. were determined to be within the range of 20.2 to 48.2% in the study areas while the other species were below 20%.Bangladesh J.

It is now possible to determine proper motions of high-velocity objects in such a way as to obtain with some accuracy the velocity vector relevant to the Sun. If a potential field of the Galaxy is assumed, one can compute an actual orbit. A determination of the velocity of the globular clusterωCentauri has recently been completed at Greenwich, and it is found that the orbit is strongly retrograde in the Galaxy. Similar calculations may be made, though with less certainty, in the case of RR Lyrae variable stars.
