THE CANADIAN ENTOMOLOGIST. 137 



Face scarcely convex, luteous ; above, a pitchy-black band separating 

 the antenna ; this band sends a median acute prolongation from the 

 anterior border toward the clypeus ; furrow, between face and inner orbit 

 of the eye, fuscous. Circumocular area luteous, except along the 

 depressed portion of the vertex. Clypeus subhexagonal, luteous, on 

 each side anteriorly an impressed dot. Labrum transverse, rounded 

 laterally and narrowed anteriorly, emarginate in front, luteous, a few hairs 

 on emargination. Mandibles piceous. 



Maxillary palpi luteous ; first two joints short, about as broad as 

 long, subequal in length, the first somewhat stouter than the second ; 

 third joint somewhat longer than the first and second together, a very 

 little curved, enlarged at apex ; fourth joint straight, a little shorter than 

 third ; apical joint a little longer than third, rufo-piceous (except at artic- 

 ulation, where it is luteous) ; truncate and notched at tip. 



Labial palpi somewhat longer than maxillary, luteous ; first joint 

 short, not quite twice as long as broad, enlarged apically ; second joint 

 about three times as long as first, somewhat curved, strongly widened and 

 thickened apically, sparsely clothed with dark hairs ; on inner side at apex 

 a perceptible concavity ; apical joint about same length as second, 

 swollen, fusiform, luteous, clothed with dark hairs ; on the outer side, 

 surrounding the ocellus-like spot, rufo-piceous ; apex narrowed, tinged 

 with rufous ; tip truncate, slightly notched. 



Maxillary palpigers luteous, clouded with darker. Maxillje luteous, 

 tinged with rufous. Labium, labial palpigers, mentum and gula, luteous ; 

 each side, next anterior portion of -maxillary palpigers, a brownish area 

 with some dark hairs. 



Antennae clavate, shorter than head and thorax ; luteous, darker 

 apically ; clothed with very short dark bristles or hairs ; first and second 

 antennal joints luteous, shining, a piceous spot or two at their bases. 

 Between the antennae posteriorly, a narrow, transverse luteous band. 



Vertex elevated behind, rounded, luteous ; in front, just behind 

 antennie, a transverse, pitchy-black band ; in front, on elevated portion, a 

 transverse, shining-yellow ridge ; behind this, four black dots in a 

 transverse row. 



Pronotum as broad as long at base, somewhat narrowed anteriorly^ 

 luteous ; anterior angles rounded, front margin truncate ; a longitudinal 

 dark fuscous stripe each side near middle line ; on the outer side of each 

 of these stripes another irregular dark fuscous stripe extending forward to
