This genus may be characterised thus : Body more slender 

 than in H cematohia ; palpi as long as probo.scis ; arista with some 

 hairs below; 3rd longitudinal vein bare at base; 4th, as a whole, 

 considerably curved (in comi)arison with that of Lypcrosia) ; ist 

 posterior cell rather narrowly open. 



I add a description of this genus to my i)ai)er, although it is 

 not yet known from the Ivast, because it ina\- casil\- occur in tin- 

 northern part of India. 



1 Not yet rerorderl from the Orient, but occurs iu .-Vraljia.
