Geographical conditions seem to militate against an extension 

 northwards, as the favourite forest habitat of Glossina palpalis dis- 

 appears north of the 10th degree. The data at present available do 

 not, however, permit of tracing with certainty the northern limit of 

 G. palpalis. G. morsifans and G. tachinoides are very common in the 

 region south of the Chad, G. palpalis is rare, and G. fusca was not 

 met with. 



The Tabanids, Tahanns thoracinus, T. taeniola and Haematopota 

 strigipennis , were captured in one locahty.

Ploiaria {Emesodema) domestica, a Reduviid bug common indoors 

 in the south of France, is recorded as preying on adult mosquitos.

 with Notes on the Relation between some of these Mosquitoes and 

 the Larva of Filaria bancrofti Cobbold. — Annotationes Zoologicae 

 Japonenses, Tokyo, x, no. 3, October 1921, pp. 45-81, 4 figs. 

 [Received 8th June 1922.] 



The new species are : Aedes galloisi, A. watasei, A. omurensis and 

 A. esoensis, from various localities in Japan; A. fiavopictus, from 

 Japan and Korea; A. chemtdpoensis a.nd A. seotdensis, from Korea; 

 and A. horishensis, A . formosensis and A. hatorii, from Formosa. 



Of 13 species of Aedes examined, A . {CtUicelsa) togoi, Theo., a common 

 mosquito in Japan, proved to be able to serve as an intermediate 

 host for Filaria bancrofti, but similar experiments with A. galloisi, 

 A . chemulpoensis and A . esoensis proved negative.

A thrips, Gynaikothrips nzcli, Zimm., swarmed in certain parts of 

 Algiers during the summer of 1920, sometimes forming dense clouds 

 and causing great annoyance. Specimens that fall on the conjunctiva 

 of the eye cause acute pain that subsides very slowly, and individuals 

 ■on the skin appear to bite [of. R.A.E., B, ix, 175].

Weevil, Calandra granaria. — Reprint from Neiv Orleans Med. 

 & Surg. JL, Ixxiv, no. 10. April 1922, 4 pp. 



From experiments undertaken and the work of previous authors 

 on this subject, it is clear that Calandra granaria does not contain 

 cantharidin, and there seems no basis for the theory that the presence 

 of the remains of this weevil in flour is responsible for cases of poisoning.
