Underside black. J3asal ventral segment covered by the femora, 

 segments 2-5 about e(|ual, the (ith (Uejily semiciicularly emarginate, 7th

 and pubescence, and less glossy surface,

 p. 328. 



Subdepressed, elongate, moderately shining; nigrescent, elytra tinged 

 with blue, legs and antennae fuscous; thinly clothed with inconspicuous, 

 rather short and slender, suberect, dark-ashy pubescence. 



Head rather broader, eyes included, than the fi-ont of the thorax; 

 bi-impressed in front, distinctly but not closely punctured, with minute, 

 dense sculpture near the sides. Thorax slightly longer than broad, 

 widest at the middle, a good deal narrowed in fiont, nearly straight 

 behind; disc slightly convex, its punctation distinct and, except on the 

 middle, moderately close, the intervals minutely sculptured. Scutellum 

 moderately large, rounded behind. Elytra thrice the length of the 

 thorax, rather broader than it is at the base, slightly wider behind; they 

 are closely punctured, more coarsely than the thorax, and in some lights 

 appear slightly I'ugose, humeral impressions shallow. 



Legs elongate; posterioi- tarsi as long as the tibiae. 



Antennae hardly as long as the head and thorax, shorter in the 

 female; 2nd joint nearh^ as long as the basal, joints 3-5 a little longer 

 than the following ones. 



In D. laticepn, 600, the thorax is not perceptibly contracted 

 anteriorly, its punctation is coarser, and the pubescence is yellowish. 

 D. co/istrlctiis, 1392, as well as 1393, have distinct yellowish setae. 

 These are the nearest allies.

 the remaining joints and the palpi fuscous. 



Head, including the large eyes, as broad as the thorax, ])roadly bi-
