THE CANADIAN ENTOMOLOGIST. 97 



variolosa Jac; the colour of the tibiae and tarsi is obscured by the thick 

 sericeous pubescence, the last joint of the tarsi is sanguineous. 



D. pachitensis, nov. sj). 



Head black, antenntie fuscous flavous, joints 9-10 white ; thorax 

 fuscous-flavous, transverse, punctate, trifoveate, scutel black, elytra 

 fuscous-flavous, obsoletely plicate, coarsely and confluently punctured, 

 each with three black stripes, a common sutural, a median discal and a 

 humeral &ublateral, all end at or just after the middle ; body beneath and 

 legs fldvous, pectus black. Length, 53^-6 mm. 



Two examples, Pachitea, Peru. 



Antennae ( ^ ) longer than the body, joints 2-3 very short and about 

 equal, 4 twice as long as the preceding two ; thorax broader than long, 

 the punctures quite coarse at the sides, the third fovea being longitudinal 

 before the scutel, sides almost parallel ; elytra strongly dilated behind, the 

 punctuation being much less evident at the rear, strong and coarse 

 anteriorly; the humeral stripe is truncated behind, shorter than the others 

 and ends about the middle ; the other stripes are gradually drawn out, and 

 end at or about the convexity; all, with the exception of the sutural, are 

 about equal in width throughout their length; the sutural is, however, 

 broader anteriorly ; the five black stripes, two on each elytra and one 

 common sutural, easily separate this form. 



D. atrobasalis, nov. sp. 



Head rufous, labrum black, antennae nearly as long as body, black, 

 with the last three and one-half joints pallid ; thorax rufous, depressed, 

 bifoveate ; scutel black ; elytra pallid-yellow, with the anterior third 

 occupied by a large quadrate black spot, which does not attain the lateral 

 margin ; body beneath, except the thorax, black; legs black, femora with 

 base and apex yellow. Length, 4 mm. 



Two examples, green label (Marcapata ?). 



Antennae with joint 2 short, 3 one-half longer, 4 equal two preceding ; 

 thorax a little wider than long, finely punctate, sides feebly sinuate ; elytra 

 not plicate, slightly depressed back of scutel, very finely and not thickly 

 punctured, the rear of the black mark almost truncate, but a little drawn 

 down at the suture, the spot extending entirely across the elytra, omitting 

 the lateral inflexed margin and a rear corner on the outside, which is 

 rounded. 



Judging by the description and figure, the species has a general 

 resemblance to bicolor Jac, fiom Nicaragua.
