54- THE CANADIAN ENTOMOLOGIST. 



between the sectors, three anteapical cells, the outer one usually stylated 

 at its apex ; five apical cells, the first triangular, the three following 

 broadly wedge-shaped, and the fifth similar to the anteapical cells ; their 

 bases and the base of the fifth apical, which is usually either a forked or 

 double nervure, broadly embossed with white obscuring the actual course 

 of the nervures. 



The flat vertex with its slight margin, the coriaceous elytra with the 

 raised nervures, and the ocelli distant from the eyes, will place this in the 

 Acoccphaliim ; at the same time the whole vertex and front strongly sug- 

 gest the genus Platymetopius, and the pattern of venation approaches that 

 found in some species of that genus. Whether this indicates relationship 

 or similar lines of development can be more easily answered when the 

 habits and life-history have been studied, and other of its relatives have 

 been found. 



Cochlorh inns pluto, Uhler. Plate 2, fig. 1. — Elongate, subparallel ; 

 vertex acutely angled, the apex produced. Black, with an irregular band 

 on the elytra behind the middle, and a triangle across the face, white. 

 Length, 6 mm. ; width, almost 2 mm. 



Genus UHLERIELLA, n. gen. 



Resembling Acocephalus in form and general appearance, but with 

 the ocelli on the sharp vertex margin, and the venation quite distinct and 

 resembling that of Cochlorhinus. Vertex slightly, obtusely angled, nearly 

 half wider than long in the female, still shorter in the male, not quite as 

 long as the pronotum, disc sloping, the margin flat or slightly upturned; 

 ocelli on the margin not quite twice as far from the apex as from the eyes. 

 Face slightly, evenly rounding, front wedge-shaped, the margins nearly 

 straight \ in profile straight or slightly convex, never concave nor with a 

 median ridge. Clypeus parallel margined, a trifle rounding at apex. 

 Pronotum as in Cochlorhinus; lateral margins rounding almost from eyes, 

 posterior margin emarginate. Elytra rather broad, varying from coria- 

 ceous to subhyaline, slightly obliquely truncate posteriorly, with the angles 

 rounded ; venation resembling that of Cochlorhinus, the outer anteapical 

 usually stylated and with two slightly divergent nervures from the apex to 

 the costa, these nervures, and often forkings of the sectors, obscured by 

 the white embossing. 



Type U. Coquilletti, Van Duzee. 



In the general plan of venation and the white embossing, the shape 

 of the pronotum and the transverse light band on the face this genus
