preceding together; basal half nearly globular; apical half 
conical, subulate. Pa/pz yellow; second joint clavate; third 
globular; fourth fusiform, pointed at both ends, sharply 
acuminate, as long as the first and second antennal joints 
together. Prothorax longer than wide, median sulcus want- 
ing; median fovea deep, connected with the lateral ones by an 
arcuate sulcus each side; lateral sulcus sharp, separating the 
convex disk from the convex marginal lobe; behind the fovea 
and basal margin is a small carina, and on each side a puncti- 
form fovea. /ytra convex, scarcely wider across the shoul- 
ders than the base of the prothorax; suture one-fourth longer; 
the width across the tip is one-half greater than that of the 
prothorax; sides divergent, arcuate behind the middle; 
shoulders low, not prominent; sutural lines not close, straight, 
punctate; discal lines short, not reaching one-fourth the 
length; disk extremely minutely and faintly punctulate. 
Abdomen nearly as wide as the elytra; basal segment more 
than one-third as long as wide; carinz short, separated by 
one-third the segmental width; lateral depression ample. 
Tarsi with the second and third joints equal in length. 4, last 
antennal joint with a basal tooth; last ventral with a round 
shallow impression. 9, last dorsal acutely produced behind. 
Habitat. British Columbia.

cence coarse. Length 2mm. Plate X., Fig. 85. 
flead impunctate, broadly convex, eyes small, fovee large, 
deep, and nude, frontal lateral tubercles large. Antenne as 
.long as the head and thorax together, with the ninth joint 
slightly transverse, the tenth strongly transverse; the last twice 
as wide as the ninth and as long as the three preceding ones 
together, truncate at the base, oblong-oval, obliquely acumi- 
nate. Prothorax as long as wide, with a deep, nearly entire 
median sulcus. A/ytra with narrow shoulders, obsoletely 
punctulate. Addomen as wide as the elytra, the basal segment 
slightly longer than one-third its width, with three equal 
transverse pubescent basal fovez, and without carine. 4, last
