THE CANADIAN ENTOMOLOGIST 177 



Anotia ; costal area rather broad ; mediastinal vein forked at the basal 

 third ; costal branch sending about two veinlets to the costa in the stig- 

 niatal region, and united by a cross vein to the outer fork of the inner 

 branch, which is straight and twice forked just before the apex. Post- 

 costal vein joining the mediastinal near the base and running straight 

 10 the apex of the elytra, parallel to the inner branch of the mediastinal 

 vein; the long, straight cell thus formed is crossed by two veinlets, one at 

 the apical third, the other near the apex. A cross vein joins the post- 

 costal with the median vein near the middle of the elytra, beyond which 

 the former sends five branches to the inner apical margin, the basal two 

 of which are themselves forked near their apex, and united by a zigzag 

 submarginal vein that reaches the claval suture ; at this submarginal vein 

 terminate the anal and the two branches of the median vein. The apical 

 forks of the post-costal vein are united by slender cross veins, which with 

 this submarginal vein form a series of about twelve apical and marginal 

 areoles from the semi-stigma to the clavus. Wing : — Mediastinal vein 

 simple, near the costa, which it touches at about the middle ; post-costal 

 vein bifid before the apex, and united by a cross vein to the mediastinal 

 and median veins, the latter of which is also bifid. Abdomen short and 

 broad, with a dorsal carina ; showing five segments above and four 

 beneath. 



The vertex and front are so compressed into the superior and frontal 

 keels that ihey might not improperly be described as wanting. These 

 keels, as in Anotia^ are united on the front and divergent posteriorly on 

 the vertex, the included space being cut out to receive the pronotum. 

 The mesonotum is convex and lozenge-shaped, the length scarcely greater 

 than the width, which greatly exceeds that of the head ; with three dorsal 

 ■carinse. Four anterior coxse long and slender, placed obliquely; pos- 

 terior short and thick. Base of the femorte approximate. The genital 

 pieces scarcely differ from those of Otiocerus. 



This genus differs from Anotia, to which it is perhaps most nearly 

 related, by the presence of ocelli, the greater length of the rostrum, the 

 smaller number of veins in the stigmatal region, etc. ; from Patara by the 

 presence of ocelli, the greater length of the rostrum, the shape of the 

 head and thorax, and the venation ; from Mysidia and Derbe (Westw.), 

 it differs in the single frontal carina, in the shape and venation of the 

 wings and the form of the eyes, but agrees with the latter genus in the
