Ur. Oswaldo Cruz received living specimens of the " vinchuca " 

 from Chile, Argentina and Brazil (Eio Grande do Sul, Sao Paulo) 

 and handed them to the author for observation. In the Spanish- 

 American countries this bug is known as the ' vinchuca,' in 

 Brazil as ' barbeiro ' (Sao Paulo and Miuas) or ' fincao,' 

 ' chupao ' (Rio Grande). The author quotes Darwin's graphic 

 description of the blood-sucking habits of this bug and the obser- 

 vations of King, Poeppig and Berg. He cannot endorse Eair- 

 maire's view that its bite causes an uncomfortable vswelling. The 

 bug is a great nuisance all over South America. 



The larvae were observed to engorge themselves in 5 minutes, 

 the nymphs in 10, and the adult vinchuca in 20 minutes. Inter- 

 vals without food may be of a duration of 4 days to many months. 

 The adult usually feeds once a week; if the last meal was small, 

 some specimens fed daily, but for about 10 minutes at a time 

 only. 



In northern Brazil Triatoma brasiliensis, Neiva, a closely 

 allied species, takes the place of T. infestans, which is not found 

 near the equator.
