THE CANADIAN ENTOMOLOGIST, 93 



impressed, though not very large ; the elytral punctures are everywhere 

 distinct, but nowhere crowded ; the specimen I have marked van shows 

 the sulcation of the elytra more plainly and has a supplemental sulcation 

 inside the shoulder over the disk ; the humeral spots are of uniform width 

 and rather truncated, and cover hardly more than the shoulder knob ; the 

 sutural line embraces the scutel, and is gradually drawn to a fine point at 

 the middle of the elytra ; the basal spots are practically the same in both 

 examples. 



D. perueiisis^ nov. sp. 



Head very dark piceous, antennae a little more than one-half the 

 length of the body, black, joints 2-3 and part of 4 ferruginous, 9-10 and 

 base of II pale ; thorax rufous, convex, shiny, with a few scattered punc- 

 tures, scutel piceous; elytra very obsoletely plicate, shining yellow, strongly 

 and evenly punctured, three basilar spots, one wedge-shaped sutural, the 

 others humeral and tapering to a point at the middle, and a heavy lunule 

 on the convexity; concave behind, dark steel blue, beneath yellow, pectus, 

 tibiae and tarsi black. Length, 5I/2 i^im- 



One example, Rio MixioUo, 1200 m., Prov. Huallagi, Peru, C. A- 

 Baer, 7-8-1900, 



I place also under this species another example from the same place, 

 having two spots in place of the lunule, and the antennae and feet lighter 

 (immature?). 



The antennae are rather stout, the joint 2 short, 3 one-half longer, 4 

 as long as the two preceding ; the thoracic punctures are very fine and 

 only visible with a strong lens ; the obsolete plication of the elytra is very 

 slight, and at first I called the elytra not plicate, but at a certain angle a 

 very slight plication is visible as a depressed or flattened space; the elytra 

 are slightlv dilated at the rear. 



Would probably be placed near dysoni Baly, which I cannot satisfac- 

 torily identify with any of my forms. 



D. rendalli, nov. sp. 



Head black, antenna? three-fourths the length of the body, yellow, 

 joints 5-8 running to piceous, joints 2-3 short, the latter a trifle the longer, 

 and 4 equal the two preceding ; thorax yellow, rather shiny, depressed, 

 trifoveate, the antescutellar fovea being transverse ; scutel yellow, elytra 

 plicate, yellow, moderately coarsely and evenly punctate, a small common 

 sutural line occupying the anterior fourth, and a sublateral line from the
