pathology and treatment of the disease are rapidly being put into 

 conclusive form. With the exception of Mexico, Latin- American 

 countries now co-operate in the work. Campaigns against Stegomyia 

 alone are beheved to be sufficient for the elimination of the disease.

Dyarina tripartita, gen. et sp. n., is proposed to replace Dyar's 

 genus Phoniomyia (not Phoniomyia as used by Theobald), and D. 

 lassalli, sp. n., is suggested for the mosquito from Trinidad recorded as 

 Phoniomyia trinidadensis, Theo., by Dyar and Knab. Keys are given 

 to the species of Sahethinus, Dodecamyia, Dyarina and Goeldia.

A number of comments are made on the questions of synonymy 

 raised in the foregoing paper.

Psorophora coffini, D. & K., the male of which is here described, 

 had hitherto only been known from the Bahamas, but has now been 

 bred from larvae in St. Thomas, Virgin Islands.

Attention is drawn to the swarming of males of Culex fatigans 

 {quinquefasciatus) round human beings at dusk in Texas.

The species dealt with are Ctilex tarsalis Coq., C. coronator, D. & K., 

 and C. thriambus, sp. n., larvae of which were found in a dirty 

 pool beside a river.

The new species described are Culex [Choeroporpa) alfaroi, C. 

 (C.) holoneus, and Aedes {Culiselsa) perichares. Culiselsa, as used 

 by the author, replaces Taeniorhynchus to avoid confusion caused by 

 the use of this name in the sense of Mansonia as employed by Theobald, 

 Edwards and others.
