Termitoxenia. — E. Bugnion {31T. Sckweiz. Eniomol. Ges., 1914, 12, 

 ■2 1 8-20). The members of this aberrant Dipterous genus are commensals 

 <of fungus-eating Termites. They are marked by their rudimentary 

 wings, and by their large, transparent, recurved abdomen. There does 

 not seem to be a cutaneous secretion for the Termites, but a secretion 

 may come from the food-canal. The food seems to be the same as that 

 of Termites, namely fungi. There are three Malpighian tubes, an 

 unusual number. The hermaphroditism alleged by Wasmann and 

 Assmuth was not confirmed by Bugnion. Perhaps a spermatheca has 

 been mistaken for a testis. J. A. T.

Food of a Millipede.— E. Rabaud {Bidl. Soc Zool. France, 1919, 

 43, 155-6). Xot much is known in regard to the diet of Myriopods. 

 In the case of Schizophylhmi mediterraneum Rabaud observed that the 

 animal browsed on a mould {Oidium) growing on the leaves of an oak- 

 tree, and proved experimentally that a diet of lichens is relished. The 

 captive specimens also ate figs and apples. J. A. T. 



Lithobiid Genera. — Ralph Y. Chamberlin [Bidl, Mus. Comp. 

 Zool. Harvard, 1916, 117-201). From a number of papers by this 

 investigator we select one on the Lithobiid genera Oabius, Kiherhms, 

 Faobius^ Arehius, Nothemhius and T'tyo&ms, small forms almost confined 

 to the Pacific coast region of North America. A. useful general account 

 is given of the life-history. The eggs of Lithobiids are rich in yolk, 

 relatively large, spherical or sub-spherical. They are laid, as in Oabius 

 pylorus, one at a time. As each is passed out it is ordinarily grasped 

 between the claws of the gonopods and often carried about for a 

 short time, so that dirt adheres to its sticky surface and renders it 

 difficult of detection. The females pay no attention to the eggs after 

 they have been deposited, whereas Epimorphous centipedes coil round 

 the egg-mass. The author distinguishes a long series of post-embryonic 

 stages up to the attainment of the full number of legs. J. A. T. 



$. Araclinida. 



Mites in Culture Tubes. — G. Billiard (Bidl. Soc. Zool. France, 

 1919, 43, 175-8). In culture tubes with various kinds of bacteria, 

 which had formed part of a military laboratory, the media were found 

 to contain eggs, larvte, and fully-formed specimens of Aleurobius farinm 

 and Tyroglyphus siro, along with moulds. The mites must have made 

 their way through the cotton-wool, and they must have brought the 

 spores of the moulds in with them. The tubes were in effective new 

 boxes, and the probability is that flies brought the mites on to the 

 cotton-wool. Indeed, investigation showed the presence of mites (of 

 the two species named and of others) on the lesrs of the flies.
