50 THE CANADIAN ENTOMOLOGIST. 



anterior band and convex anteriorly, the (f tubercle is on the forward 

 edge. This species is, so far as I am aware, the only one in §[ where the 

 ^ has a sutural tubercle. It is of course nearly allied to those forms in 

 the Baly-Gahan paper covering §2 " C." 



D. so?igoensis, nov. sp. 



Head black, antennae, thorax, scutel and legs flavous, thorax 

 bifoveate, elytra plicate, strongly punctate, pale flavous, with three basal 

 spots, one common, wedge-shaped sutural, the other oblong humeral, and 

 an oblique patch on the convexity behind the middle, and equidistant from 

 the margin and suture, all vivid cyaneous blue. Length, 5 mm. 



One example, Songo, Bolivia. 



The mouth-parts are yellow, frontal fovea very large and round, 

 antennte longer than half the body, joints 2-3 short, the latter one-half 

 longer than the former, 4 equal to the two preceding ; thorax about 

 as long as broad, sides moderately sinuate, surface smooth, deeply 

 bifoveate and depressed at rear; the elytra are slightly dilated behind, 

 and the punctuation, especially forward, is comparatively coarse, the plica- 

 tion is not strong, and the suture is slightly depressed behind the scutel, 

 the humeral blue marks are truncate at the rear. Comes near ^-inacidata 

 Fabr. 



D. klagii, nov. sp. 



Head piceous brown, antennae fuscou"^, prasinous at the base, thorax 

 prasinous, convex, shining, impunctate, scutel flavous, elytra flavous, 

 plicate, lateral edge prasinous, a common elongate sutural, a humeral, a 

 median discal and a large apical blotch, chocolate-brown ; body beneath 

 and legs flavous, with the under part of the thorax, the antepectus and 

 femora prasinous. Length, 6 mm. 



One example ( ct ), St. Catharine, Brazil (Klages). 



This si)ecies has superficially the appearance of ii-punctata Jac. 

 The antennce are a linle more than half the length of the body, joints 2-3 

 short and of equal length, the third obconic and stout after the manner of 

 the forms near simulata Baly, fourth joint slightly longer than the two 

 preceding (or the longest of all) ; the joints 4-10 are somewhat thickened 

 and dilated so they appear stout, the thorax is very sinuate behind ; the 

 plication of the elytra is strong and about two or three sulcations indicated 

 between it and the suture, the depression behind the scutel is narrow but 

 well marked, and the punctuation is fine and even. I place it next 

 iTpiinctata Jac, from which it is at once sei)arated by the smooth thorax 

 and incrassate antennie.
