A New Genus of Deticinae. 



By JAMES A. G. REHN. 



The species on which this genus is founded was described 

 by the writer (Trans. Amer. Ent. Soc., XXVII, p. 89) as a 

 species of Capnobotes, but a closer study of the descriptions and 

 plates of allied genera has confirmed the belief that it is generi- 

 cally distinct. The generic characters would be as in the sub- 

 joined diagnosis. 



NEOBARRETTIA n. gen. 



Pronotum saddle shaped, the posterior portion being elevated 

 much more than the anterior portion ; pro- meso- and meta- 

 sternum with paired spines, those of the metasternum being the 

 stoutest and those of the prosternmn the most slender ; tegmina 

 and wings abbreviated, the former broadly rounded.

 Soc., XXVII, p. 89. 



I take pleasure in dedicating this remarkable genus to Mr. 

 Otis W. Barrett, who collected the three types at Rio Cocula, 

 State of Guerrero, Mexico. 



This genus is one of the most interesting and remarkable in 

 the subfamily. The position of it would probably be between 

 Capnobotes and Apote, though this is hardly more than conjec- 

 ture, as I cannot examine specimens of those genera to study 

 the correlation of characters which seem so distinctive in speci- 

 mens of the new 7 genus. 



Professor Lawrence Bruner informs me that he has a speci- 

 men of the new genus collected by Mr. Barrett at the same 



locality.

Three New Species of Diptera. 



By D. W. COQUILLETT. 



In the course of investigating the spread of diseases through 

 the agency of insects, Dr. L,. O. Howard encountered three 

 new species of Diptera, and as it is desirable to exclude- from 

 his report all matter of a purely technical nature, a description 

 of the new forms is offered herewith :
