THE CANADIAN ENTOMOLOGIST. 99 



late and setose punctures with small punctures intermixed, the 

 granules coarser and acute on the sides; the third interspace strongly 

 widened at the base, sw^ollen and densely, finely granulate; the 

 short abrupt declivity with a rounded prominence on each side 

 above, finely, closely granulate and setose-punctate, without 

 striations, moderately concave apically, with the caudal margin 

 subtruncate, bisinuate, and the lateral angles rather strongly 

 dentate. 



The metasternum is smooth and shining, finely punctured, 

 the pubescence slender, the median line deeply striate on the 

 caudal two-thirds; the abdominal sternites are closely, finely, 

 granulate-punctate and clothed with slender hairs, the last more 

 densely granulate; the last three sternites with the cephalic and 

 caudal margins somewhat elevated, the last sternite rather dis- 

 tinctly concave therefrom. 



The male has the epistomal margin more deeply though very 

 broadly emarginate dorsally with the inferior lobe more prominent; 

 the front similar though less deeply concave and with somewhat 

 shocter hairs; the pronotum similar, lacking the densely punctured 

 median area, but with a median black line in the same position 

 and very distinct; the elytra wdth the sides parallel for three- 

 fourths the length then strongly arcuately narrowed to the in- 

 dividually strongly produced apices, the lateral margin concave 

 at the base of the prolongation ; the apical prolongations each slight- 

 ly longer than wide, emarginate at the apex, with the outer angle 

 much longer than the inner, blunt and obtusely carinate above from a 

 continuation of the united 2nd and 3rd interspaces, the carina ending 

 in a third blunt point on the dorsal apical margin of the prolongation ; 

 with a smaller tooth betw^een the dorsal and outer teeth and three 

 serrations between the dorsal and inner teeth; the suture, viewed 

 from the side, straight on the basal two-thirds, and gradually 

 depressed on the caudal third to the apices, without an abrupt 

 declivity; the strial punctures notably coarser than in the female; 

 the interspaces somewhat more convex; the second less strongK- 

 widened at the base and more finely granulate; the interspaces 

 minutely, uniseriately punctured on the disc, but not striate; the 

 punctures coarser, more numerous and finely granulate at the 

 base of the 1st and 3rd; on the depressed caudal third all the inter-
