Type: Micromus areolaris, Hagen, North. Amer. Neurop., p. 199, 



This curious little insect evidently belongs to the Osmylida in the 

 sense defined by Brauer ; and Hagen, in his " Synopsis synonymiea," had 

 already placed it doubtfully in the genus Sisyra, at the same time indi- 

 cating that a new genus should be formed for its reception. From 



Sisyra it differs in the pre- 

 ^^^X3^rr-TT~~~_ sence of a veinlet at the 



base of the sub-costal area, 

 and of two well-defined 

 series of gradate veinlets ; 

 also in the elongated pro- 

 thorax, and long triangular 



Anterior wing of Climacia areolaris. f ace# J ^ aye indicated the 



presence of two curious setiform organs, apparently connected with the 

 maxillae, but am by no means sure of their actual position and relation- 

 ship. 



Hagen received the insect from Florida (March) ; I possess a pair 

 from Bosque County, Texas, taken by Mr. Belfrage (in August) . It is 

 probably aquatic in its earlier stages.
