58 THE CANADIAN ENTOMOLOGIST. 



D. rosenbergi, nov. sp. 



Head dark piceous, antennae nearly as long as body, fuscous, with 

 three upper joints fiavous, thorax dark olivaceous, rather opaque, bifoveate, 

 scutel piceous, elytra castaneous, with prasinous suture and margin, 

 vanishing before the apex, and one or more cross bands of the same,, 

 indicated before and behind the middle ; body beneath flavous, with 

 piceous breast, legs with prasinous femora, and piceous tibiae and tarsi. 

 Length, 6-7 mm. 



Three examples, two 9 'Sj one ^ , R. Dagua, Columbia, Rosenberg. 



This comes near dviaculata Baly, and also curvipiistulata Baly, but 

 differs in colour of the head, and the last three joints of the antennae being 

 pale, the elytra also are not spotted but wholly suffused, though I assume a 

 larger series might show distinct spots. My $ has the antennae nearly 

 as long as the body, joints 2-3 short and equal, the latter, however, more 

 obconic in shape, 4 nearly twice as long as both preceding, and 

 easily the longest joint of all, three upper joints pale flavous, the extreme 

 tip of the last piceous, the thorax and elytra are entirely castaneous 

 (faded ?) with a touch of piceous on the suture, the shoulders, and in the 

 disk before and behind the middle ; the punctuation of the elytra is thick 

 and moderately coarse, and there are several indistinct sulcations on the disk. 



D. riifopiistulata, nov. sp. 



Head prasinous, mouth piceous, antennae prasinous, becoming fuscous 

 at middle and end, thorax shining prasinous, deeply bifoveate, scutel 

 piceous, elytra prasinous, almost parallel, depressed, strongly plicate, and 

 punctured, each side with a bright rufous, round spot on the disk in front 

 of the middle, and rather distant from the suture, also an indistinct rufous 

 spot near the apex on the convexity, legs prasinous, tarsi and apex of tibia 

 piceous, abdomen yellow, pectus black. Length, 414 mm. 



One ( $ ?) example, La Paz (Bolivia?), green label. 



Antennae about half length of body, joints 2-3 short and equal, 4 equal 

 the two preceding, basal joint prasinous, then the colour gradually grades 

 up to the eleventh joint, which is dark fuscous and the darkest of all, 

 thorax is rather longer than broad, and nearly parallel, and the fovea large 

 and deep, elytra rather dull, with the thick punctuation, flat, also depressed 

 along the suture, the plication below the shoulder very strong and deep. 

 The noticeable thing about the species is the rufous anterior spot, which is 

 easily visible, and at once distinguishes this species.
