(lerraan into Portuguese. The book is divided into the following 

 chapters : I, The mosquitoes of Para considered as a public calamity ; 



II, Review of results of experiments made in 1903, particularly with 

 Stegomyia fasciata and Culex fatigans, from the sanitary point of view ; 



III, Biological details ; IV, Stegomyia fasciata, the transmitting mos- 

 quito of yellow fever and the actual state of knowledge relative to the 

 cause of the disease. The author did not, however, bring all his data 

 together under their respective headings, which is troublesome to the 

 reader, but perhaps inevitable with such wealth of material. 



The first chapter opens with an introduction to the Culicidae, 

 definition of some of the more important genera and data on the dis- 

 tribution of species culled from Theobald's Monograph. The author 

 then turns to the species of Para. Of the 42 species recorded from 

 Brazil, 18 have been found at Para, 17 of them by the author; five 

 of these are new. This seems a very small showing for so favorable 

 a locality ; but this is perhaps due to the fact that the author has given 

 most of his attention to the biologic and economic part of the subject. 

 I will only mention in comparison that more than 50 species of mos- 

 quitoes are known from the Island of Trinidad, and indications are 

 that it is by no means exhausted. The genera known from Para are 

 Anopheles, Megarhinus, Psorophora, Janthinosoma, Stegomyia, Culex, 

 Tceniorhynchus, Sabethes, Hicmagogus, Wyeomyia, Limatus and Tri- 

 choprosopon. A number of these genera are not treated in the present 

 work, but the author promises an account of them in a future paper. 

 Then follow short notes on some of the species. Megarhinus separatus 

 is not rare in the vicinity of the city. It is strictly a forest mosquito 

 and diurnal. Its bite is reputed to be painful, but the author has not 

 yet been able to verify this from personal experience. Jauthinosotna, 

 of which the author has taken J. musica, is dismissed, as, in the au- 

 thor's experience, of no faunistic importance. This seems remark- 

 able, as elsewhere in tropical America Janthinosoma is one of the 

 most conspicuous forms. In connection with Stegomyia fasciata its 

 excessive abundance in the city, its diurnal habits and severe bite are 

 noted. In the reviewer's experience the bite of Stegomyia can hardly 

 be called severe : indeed the bite is often hardly noticeable, and this, 

 together with its stealthy habits, the more easily make it the transmit- 

 ter of the dread yellow fever. Culex fatigans is spoken of as a hor- 

 rible nocturnal scourge in certain parts of the city. Tcenior/iyuchus 

 is crepuscular, invades the dining room, flies onto the table and into
