is the largest blood-sucking insect attacking man. The presence of 

 Chagas' disease in a locality may be diagnosed with more certainty 

 by examination of the intestinal contents of Triatoma than in any 

 other way. The State of Espirito Santo appears to be the chief habitat 

 of the species.

The author received from Dr. L. E. Hurtado of the Republic of 

 San Salvador a number of examples of Triatoma dimidiata, Latr., var. 

 macidipenniS) Stal, and Rhodnius prolixus, Stal, together with the 

 information that he had found T. dimidiata infected with crithidial 

 forms of Trypanosoma cruzi, and had infected guineapigs and rabbits 

 after 25 days of incubation. Besides T. dimidiata, T. rugulosa, Stal, 

 is found in Costa Rica, T. venosa, Stal, in Costa Rica and Panama, and 

 T. rufotuherculata, Champion, in Panama.

In this memoir to the 5th Latin- American Medical Congress, it is 

 stated that the period of prevalence of malaria in Peru varies with 

 the time of the year and is not coincident with the period of maximum 

 prevalence of mosquitos. Near Lima, most cases of malaria occur 

 from January to June, while mosquitos are most abundant in the 

 remaining six months, which are dry and cool. A. superpictus, or a 

 variety of this species, is the mosquito chiefly met with.

The addition of 1 : 3,200 of lysol was found to kill the mosqnito 

 larvae in tubs in a hospital. The addition of 1 : 5,000 of copper sulphate, 

 with sufficient sulphuric acid to prevent precipitation, also kills the 

 larvae, but does not prevent them from hatching. Copper sulphate 

 moreover does not communicate a taste to drinking water which may 

 be subsequently kept in the containers, while lysol fails in this respect.
