 This species is of a bronzy olive hue above, vv^ith the middle 

 of the labrum, the basal joints of the palpi, the under side of the 

 thighs, the tibia?, the tarsi, an arcuated fascia extending from 

 the shoulders to near the suture at one third from the base, a 

 zigzag fascia about the middle enlarged at the sides and not 

 reaching the suture, and the apex of the elytra, of a pale yellow. 

 The antennse, excepting the basal joint, and the apex of the 

 tibise, and of each joint of the tarsi, are black. Between the eyes the 

 head is marked with a number of fine longitudinal striolae, on 

 the back of the head the striolee are transverse. The thorax 

 is a little longer than the breadth, and is marked with 

 transverse strioljB ; the median line is distinct, and the transverse 

 depressions near the apex and base are very deep. Between 

 these depressions the sides of the thorax are slightly rounded. 

 The scutellum is short, broad, depressed in the middle and 

 pointed at the apex. The elytra are a little broader than the 

 thorax, square at the shoulders, parallel-sided, and round at the 

 apex. The sculpture consists of, fine wavy transverse striolee on 

 the middle, and punctures on the sides. The legs are thinly 

 clothed with short white setae. The under surface is of an uni- 

 foi^m brilliant bluish black. 



All the species of this genus very much resemble one another, 

 and a mere description without comparison would scarcely sufiice 

 for the certain recognition of any one of them. In this case the 

 strongest resemblance is to D. tmdulata Westw., it differs in being 

 very much smaller, in having the indentations on the sides of 

 the labrum much deeper, in the flatter and less laterally rounded 

 thorax, in the smoother and less deep sculpture of both thorax 

 and elytra, in the shorter scutellum, in the absence of a smooth
