 moubnta with Trypanosoma {Schizotrypanum) cruzi.] — Arch. f.

 pp. 158-160. 



In 1914 Rocha-Lima and the author recorded the lasting infection 

 with Trypanosoma cruzi of Conorhinus megistus, Cimex lectularius 

 and Ornithodorus moubata. The infection lasted for more than two 

 years in C. megistus and for several months in the bed-bugs and ticks. 

 The work had to be discontinued, but it was found possible to keep 

 the infested ticks under observation, and even after five years, the 

 presence of virulent parasites in their gut was proved by inoculation. 

 It was never possible to obtain infection from their progeny, nor 

 could any flagellates be discovered in them, so that there was no 

 inheritance of infection.

A preliminary report on dengue in Australia has already been 

 abstracted [see this Revieiv, Ser. B, iv, p. 196] and records all the 

 facts concerning transmission by Stegomyia fasciata. In the present 

 paper the work is dealt with in detail.

Since 1910 many observers have reported finding an organism in 

 typhus-infected lice which they beheve to have a causal relationship 

 to typhus fever. The authors have been able to cultivate this organism 

 in Mexico and show that it is identical with Bacillus typhi-exanthematici.

 in the Bandoeng Plateau.] —Geneesh. Tijdschr. v. Nederlandsch- 

 Indie, Batavia, Ivii, no. 6, 1917, pp. 749-752, 2 plates. 



A collection of mosquitos from the Bandoeng plateau, where one 

 locality is kno^^^l to be malarial, included the following Anophelines : — 

 Anopheles (Myzorrhynchus) barbirostris, A. {M.) albotaeniatus, A. (M.) 

 sinensis, A. (Myzomyia) ludloivi, A. (M.) rossi var. indefinitus, 

 A. {M.) punctidatus, A. {M.) aconitus (albirostris), and A. (Cellia) 

 Jcochi. 



Other mosquitos included Culex spp., Stegomyia fasciata [calopus), 

 S. pipersalata, and S. albopicta {scutellaris). One of the plates 

 illustrates characters of the last-named species, while the othet figures 

 Stegomyia pipersalata. Details of the latter are also given in the text.
