Previous surveys (2011–2013) of the bee fauna from the Suez Canal region, Egypt, recorded a total of 55 species.  Those surveys did not include important floral species among the Asteraceae, a family known to be associated with various oligolectic bees.  The aim of the present note is to report bees visiting four uncultivated species of Asteraceae that are common in the region during the Spring of 2014.  Nine species of bees were recorded from these flowers, these increasing the number of species recorded from the Suez Canal region to 62.  Some species, such as Daypoda sinuata Pérez (Melittidae) and Panurgus dentatus Friese (Andrenidae), are known oligoleges of Asteraceae.

Summary The diversity of solitary bees varies depending on the vegetation, nesting habitats, and nesting fragmentation. The agriculture development in the Suez Canal region is receiving a great deal of attention in Egypt, thus, the diversity of solitary bees are essential for high quality production of seeds, vegetables, and fruit. The objective of this study was to evaluate the biodiversity of solitary bee populations around the Canal region. About 900 - 1000 specimens of bees were collected from different locations of the Ismailia, Suez, and Sinai Governorates. Fifty-five species of bees were identified. With the exception of Melittidae family, all the bee families were present in the Canal region. The total number of species for each family were 7, 9, 11, 13, and 15 species for Andrenidae, Colletidae, Apidae, Halictidae, and Megachilidae, respectively. Lasioglossum mandibularie (Morawitz, 1866) is a newly recorded species collected from Egypt. In the Suez Canal region, the most abundant species found with large populations were Andrena ovatula ssp. ovatula (Kirby, 1802), Ceratina tarsata Morawitz, 1872, and Colletes lacunatus Dours, 1872.

Oligolectic Bees

Evolution of flower specialization in bees, the concepts of poly-, oligo- andmonolecty are reviewed. About 60 species recorded in the area of Finland and Sweden are regarded as oligolectic. The proportions of oligoleges among all pollen-collecting bee species are about 30 percent in alarge area of central and Northern Europe. The proportion is about 15 percent in the northern boreal area of Finland and Sweden, where the percentage of polylectic bumblebees is much greater than in more southern areas. Of the solitary bee species recorded in Finland and Sweden, 25 arc regarded as narrow oligoleges, of which 6 species collect pollen from Campanula and 5 from Salix. Eusocial Bombus consobrinus is regarded as a facultative narrow oligolege of Aconitum septentrionale and, apparently, this bee species is the only oligolege in northern Europe, whose distribution completely covers that of the pollen plant. The distribution limits of some narrow oligoleges (e.9. Eucera longicornis and Andrena hattorfiana) approximately follow certain frequencies of their principal pollen plants (lathyrus pratensis and Knautia, respectively). Of the oligolectic bee species in Finland, 32 occur on the lists of threatened species of England, southwestern Germany or Poland. Records of E. longicornis and A. hattorfiana from various periods are given as examples of the decline of oligolectic bees in Finland during recent decades.

A New Species

A Considerable number of species of Tetrabelodont Mastodons are already known from various horizons and localities in the United States. Several of these from the Loup Fork deposits have been described by Cope, the best known being Tetrabelodon euhyphodon, T. campester, and T. productus. A fairly complete mandible recently acquired by the British Museum seems to indicate that yet another very distinct form existed contemporaneously with those just mentioned. This specimen, which forms the subject of the present note, was obtained from Mr. Sternberg, the well – known collector of fossil Vertebrates, who refers to it in his recently published work The Life of a Fossil Hunter (p. 123) under the name Trilophodon campester, Cope, from which, in spite of some similarity, I believe it to be very distinct.

Effects Of Temperature

In my previous paper I endeavoured to establish a basis for calculating the amount of fresh air necessary to keep an air-space sufficiently pure or health, taking the carbonic acid as the measure. The results showed that the mean amount of carbonic acid as respiratory impurity in air undistinguishable by the sense of smell from fresh external air was under 0·2000 per 1000 volumes . My object in the present note is to call attention to the relative effects of temperature and humidity upon the condition of air, as calculated from the same observations. If we adopt the figures of Class No. 1 (that is “fresh,” or not differ­ing sensibly from the external air) we find the following:—
