14 THE CANADIAN ENTOMOLOGIST. 



humeral, and a common triangular, elongate sutural, and two or three 

 small spots triangularly placed at the middle of each elytra black. Length 

 5-5)4 mm. 



Six examples, Marcapata, Peru, and also Bolivia (Mapiri ?). 



Resembles some of the forms of lo-punctata Latr.; antennae about 

 three-fourths the length of the body, wholly black, joints 2-3 short and 

 about equal in (^ , 3 a little longer in $ , 4 longer than the preceding two 

 united, noticeably so in ^ , thorax about as long as wide, convex, shining, 

 sparsely, finely punctulate, very sparingly on the disk, two small foveas 

 faintly indicated, one on either side of the middle, sides nearly straight • 

 scutel black ; elytra slightly dilated at the rear, and depressed back of the 

 scutel, punctuation finer behind ; the elytra show a suffused orange- 

 colour, which seems normally to be a cloudy vitta from the shoulder to 

 the ajiex ; in some examples it is almost wanting, and in others the orange 

 tint suffuses nearly the whole elytra. The humeral spot is round, the 

 sutural, elongate triangular, about i mm. long ; there is a small round spot 

 on the disk just before the middle, another between the last and the 

 margin, but a little to the rear, and a third on the disk, in line with the 

 first but about the beginning of the convexity, in some examples there are 

 indications of a fourth spot between the last and the margin, and in others 

 the third spot is absent ; probably examples occur in which some or all 

 the other elytral spots disappear; body beneath and legs black, except 

 the abdomen and thorax are yellow. 



The species has been distributed with the manuscript name of 

 semiviridis Jac. Three of my specimens were sent me as cotypes by 

 Messrs. Staudinger and Bang-Haas ; the typical form I regard as the one 

 with the three discal spots ; distinguished from lo-pwidata Latr. by the 

 coarse punctuation of the elytra, the thorax also seems to have the sides 

 less sinuate. 



D. piceopunctata,nov, s\). 



Head, breast and scutel black, antennae flavous, fuscous in middle 

 and at end, thorax yellow, convex, finely punctate, elytra obsoletely 

 plicate, bright yellow-prasinous, shining, with common sutural triangular 

 spot, a humeral, two lateral, and a small, submedian discoidal spot, rufous 

 piceous ; body below yellow, legs yellow, with tarsi and outside of tibiae 

 faint piceous. Length 5^^ mm. 



One example, San Augustin, Mapiri (M. Stuart).
