92 THE CANADIAN ENTOMOLOGIST. 



D. sei/iisuc/afa, nov. sp. 



Head black, antennte slender, nearly as long as body, flavous, 

 gradually darkening lo joints 9-ro, which are pale, ir piceous; 2 short, 3 

 a trifle longer, 4 nearly twice as long as both preceding together; thorax 

 about as broad as long, rufous, shining, convex, finely and sparsely 

 punctate, an obsolete depression in front of the scutel, which is rufous ; 

 elytra flavous, shining, rather thickly and coarsely punctate, very strongly 

 sulcate plicate, with a supplemental sulcation from the humerus over the 

 disk, three spots at the base, one small wedge-shaped sutural, the other 

 humeral, broad, extending to the middle; also two spots transversely 

 parallel at the rear, one discal on the convexity, the other lateral, the 

 latter in line with the humeral, all black, below and legs yellow, pectus 

 black. Length, 6Y2 mm. 



One example, Peru, square, pale, olive-green label (Callanga ?). 



Will be placed in division O (Baly's paper), but is very distinct from 

 any there mentioned; the sinuation of the thorax is slight, but the dilatation 

 in fr )nt is marked, and the reflexed edge is very noticeable behind. The 

 sutural black spot does not attain the base, and is drawn to a fine point at 

 about one fourth the length of the elytra ; the rear spots are both parallel 

 to the suture; the plica extends from the shoulder to the rear outside spot, 

 and takes the form of a deep groove. 



D. bacri, nov. sp. 



Head black, antennae three-fourths as long as body, fulvous at base, 

 la=;t three joints (the upper half of last excepted) pale; thorax rufo-flavous, 

 smooih, convex, bifoveate, scutel piceous, elytra shiny, obsoletely plicate, 

 fl.ivous, dilited behind, distinctly evenly punctured, with a thin, common 

 scutelar line, a short humeral spot, a small median discal, and two small 

 postmedian spots on the convexity, placed obliquely in the usual manner, 

 black beneath and legs yellow, with pectus black, and tarsi tinged with 

 piceous. Var. elytra with only the basal spots. Length, 7 mm. 



Two examples, Rio Mixiollo, 1200 m., Prov. Huallaga, Peru, C. C. 

 B-ier, 7-8-1900. 



The elytral markings would place this form somewhere near 

 apicicornis Jac. = palpalis Jac, but the body is even more dilated than in 

 the former. The joint 2 of the antennae is short, 3 stout and barely one- 

 half longer, 4 longer than the two preceding, 5-8 black ; thorax is wider 

 than long, barely depressed in front of the scutel, a few minute punctures 

 at the lateral edges, which are moderately sinuate; the fove?e are well
