In splitting off this genus from Hceiiiatohia , R. Des., Rondani 

 in a table of genera gave the following diagnosis of it : " Arista 

 hairy only on upper side, the hairs wav}^ ; 2nd longitudinal vein 

 reaching the costal opposite the small cross-vein." In this genus 

 Rondani placed two species, " irritans, L.," and " serrata, R. D." ; 

 Prof. Bezzi very kindly supplied me with notes on this genus from 

 Rondani' s work, and informs me that that author was mistaken in 

 his identification of irritans, L., having another species before him 

 at the time, and for this species my correspondent proposes the 

 name of titillans (Rend. Istit. lomb. (2), xl, 24). 



^Moreover, Rondani's " serrata^ R. D." was the true im'faiis, L. 



LYPEROSIA, Rond. 



{Revised description.) 



Bod}' more elongate than in Stomoxys ; abdomen about twice 

 as long as broad. E3'es bare, approximate in cf , frons in 9 about 

 ^ width of head. i\ntennae according to Rondani inserted at the 

 middle of the eyes, with the 3rd joint a little longer than the 2nd, 

 but I should describe them as inserted very slighth^ lower on the 

 face than in Stomoxvs. Antenniie plumose on upper side only, the 

 hairs undulating. Proboscis as in Stomoxys ; palpi comparativeh' 

 stout and broad, as long as proboscis, less bristly than in Hcematobia. 

 Apical part of 4th longitudinal vein curved rather less than in 

 Stomoxys and Hceinatobia, the whole vein being considerably 

 straighter, and without the definite ' ' elbow ' ' so usual in the 

 higher Muscinre; 3rd longitudinal vein bare at base ; ist posterior 

 cell comparatively broadly open ; sterno]:)leural bristles yellow.
