This is the last of three preliminary papers on German mosquitos 

 [R.A.E., B, vii, 69, 173]. Generic and specific keys, based on the 

 male genital characters, are given together with brief notes on the 18 

 species concerned.

 ihre Larvenstadien. [The Elk Throat Bot-Fly, Cephenomyia 

 idrichi, Brauer, and its Larval Stages.] — Centralhl. Bakt., Parasit. 

 u. Infektionskr., Jena, Ite Abt., Orig., Ixxxiv, no. 7-8, 14th August 

 1920, pp. 541-554, 2 plates. [Received \lih November 1920.] 



A detailed description is given of the various larval stages of the 

 Oestrid, Cephenomyia ulrichi, Brauer, infesting the nose and throat 

 cavities of the elk. 



It is not possible to compile an accurate key to the third-stage 

 larvae of these flies, but the author gives, with some alterations, 

 Bergman's key to those of C. stimulator, Clark, C. riijibarbis, Mg., 

 C. ulrichi, Br., and C. trompe, L. Brauer's key to the adults of these 

 four species is also quoted.

This is a popular article, a section of which deals with malaria and its 

 Anopheline transmitters and also with Chagas' disease, of which 

 Triatoma megisia is the vector. Illustrations are given of all stages of 

 this bug and of the typical thatched mud cabin in which it abounds. 

 The chief prophylactic measure advocated is the construction of well- 

 lit, airy dwellings of which the walls have a surface that is quite 

 smooth and without cracks. The introduction of these and other 

 sanitary measures has caused this disease to disappear entirely from 

 Bello Horizonte, which is now one of the healthiest towns in Brazil.

 Zoological Museum at Hamburg. Third Contribution to the

Most of the Anoplura of the Hamburg Museum have been worked 

 out by Mjoberg, but the following additional species are described : — 

 Pediculus humanus chinensis, subsp. n., probably from Chinese ; Pedi- 

 ciniis paralleliceps colobi, subsp. n. ; Haematopinus stiis chinensis, 

 subsp. n. ; H. suis germanicus, subsp. n., from Sus scrofa domesticus ; 

 H. minor, sp. n., from Equus burchelli ; Linognathus coassus, sp. n., 

 from a deer, Coassus sp. ; and L. gilvus, sp. n., from a duyker, 

 Cephalophus sp.
