58 THE CANADIAN ENTOMOLOGIST. 



thoracic fovea are well marked and connected by a well-marked depres- 

 sion, and one example has a median piceous mark at the rear. The elytra 

 are much wider than the thorax, convex, very thickly punctured, almost 

 obsoletely granular, the black spots relatively small but very conspicuous. 

 Somewhat similar in shape and appearance to 'j-piinctata Jac. from 

 Parada, Mex. 



D. bicincta^ nov. sp. (Jac. in litt). 



Head black ; antennae . black, last 3 joints ( ^^ ?), or 4 joints ($?), 

 fiavous, except tip of 11. Thorax punctured, flavous, trifoveate ; scutel 

 black ; elytra thickly and rather coarsely punctate, flavous, a broad basilar 

 and somewhat narrower submedian fascia dull black, neither quite attain- 

 ing the margin. Thorax beneath and mesosternum flavous, rest of body 

 black, legs black with yellow femora. Length, 4)^-5 mm. 



Five examples, Marcapata, Peru. 



This form has been distributed with the manuscript name bicincta 

 Jac. Four co-types have been sent me by Messrs. Staudinger & Bang- 

 Haas. It is a pretty little species, and easily recognized by the two black 

 fasciae. The antennae are long and slender, and nearly equal to the length 

 of the body in the $ . The apparent difference in the number of white 

 joints may be significant of similar variation in other so-called species. 

 The elytra are depressed near the scutel and not at all plicate ; in one 

 example the suture is very narrowly black between the bands. One 

 example has the rear band abbreviated into two spots, the anterior band 

 much narrowed, and joint 8 of the antennae half black and half white. 



D. parambaensis, nov. sp. 



Head rufous ; front in the $ profoundly excavate concave, in the 

 9 convex ; antennae flavous, fuscous at tip, joint 2 very short, 3 several 

 times longer than 2 in the ^, stout, curved, and a trifle longer than 4 ; 

 in the Ç relatively shorter, equal to 4 and both joints cylindrical. Thorax 

 rufous, polished, distinctly pimctulate, deeply bifoveate and obsoletely 

 depressed before the scutel, which is black ; elytra shining black, punc- 

 tured subseriately on the disk, becoming obsolete behind, the tip moder- 

 ated, and a narrow median fascia bright, yellow. Thorax below red and 

 black, body black, edges of the segments narrowly flavous, legs bright 

 yellow, extreme tip of tarsi fuscous. 



Var. A with small yellow subbasal median dot. 



Six examples of typical form, "Paramba 3500 iv; '97," dry season 

 (Rosenburg) ; 14 examples from Cachabe seem the same, though smaller,
