distinct lamellae between the antennae. The branch 

 issuing from the second transverse cubital nervure is short ; 

 the abdominal segments are smooth without any striations 

 as in Microdes ; the furrow on the mesopleurae is wide and 

 deep, and obscurely marked with keels. My only example 

 wants the apex of the abdomen.

Ophion. 



This genus is divided into two sections, according to 

 the neuration of the anterior wings. 



A. The basal abscissa of the cubitus not thickened ; 

 the cubital nervure with an abbreviated projection opposite 

 the base of the stigma = Qv\\\0"&, sensu Lat. 



The two species here described may be separated as 

 follows : 



(a) The recurrent nervure received opposite the end of 

 the basal abscissa of the radius ; the depression at the 

 base of the median segment indistinct, triangular; the 

 middle lobe of the mesonotum fuscous ; the basal trans- 

 verse keel on the median segment indistinct. 



O. fuscomaculatus. 



{b) The recurrent nervure received distinctly in front 

 of the end of the basal abscissa of the radius; the 

 depression at the base of the median segment large, deep, 

 semicircular; the basal transverse keel distinct; the orbits 

 and vertex broadly yellow. O. areolatus.

This species agrees with O. univittatus Lep. in having
