lobes much broader and shorter than in Amnesia, the eyes being 

 invariably far distant from the prothorax. The three species ma}' 

 be distinguished as follows : — 



Elytra! siiture prominent and keeled near the summit of the posterior declivity ; 

 serial punctures each with a rather large scale hut otherwise nude. 

 Serial punctui'es small; hind tibiiic ver^^ strongly bent near the apex in the 



male segiiis 



Serial punctures much coarser ; scales brilliantly metallic in color ; hind tibite 



of the male only very feebly arcuate toward apex lecoiitei 



Elytral suture not keeled near the apex but with a small and abruptly ele- 

 vated double tubercle; serial punctures not squamigerous but each with a 

 short hair attached anteriorly; scales in great part opalescent. .verriicifer 



D. segnis of LeConte (Pac. R. R. Rep., 1857, App. 1, p. 56), is 

 rather abundant in the northern parts of California; it is uni- 

 formly and soberly clothed with small rounded pale brown scales 

 having a pearly lustre, but which become feebly metallic beneath 

 and on the legs. 



I>. lecoiitei n. sp. — Elongate and narrow, strongly convex, black, the 

 antennaj and legs black throughout; scales small, rounded, dense thi'oughout, 

 pale greenish with coppery reflections, indefinitel}^ nubilate with blackish on 

 the elytra and still more indefinitely clouded on the pronotum, the paler 

 scales more conspicuous on the femora in outer third. Head one-half as wide 

 as the prothorax, the head and entire beak densely clothed with greenish scales 

 intermingled with short hairs; interocular fovea wanting; eyes separated by 

 three times their own width; beak stout and thick, not twice as long as wide, 

 dilated at apex, thinner toward base in profile, two-thirds as long as the 

 prothorax, the transverse impression distinct; antenniB very long and slender, 

 the scape extending rather beyond the base of the eyes, very slender, thickened 

 at apex, funicle as long as the entire prothorax, all the Joints elongate, the 

 two basal greatly so, seventh longer than the sixth, club narrow, elongate and 

 acutely pointed. Prothorax as long as wide, the sides parallel and broadly 

 arcuate, more convergent near the base, the latter subequal to the apex, both 

 subtruncate, the ocular lobes short, broad and fimbriate; disk finely, sparsely 

 and scarcely visibly punctate, squamose and with short erect brownish hairs. 

 Scutellum extremely short, scarcely entering the disk. Elytra elongate, twice 

 as long as wide, only slightly more than twice as long as the prothorax and 

 but very sligbtly wider; sides jiarallel and very feebly arcuate, rather nar- 

 rowly rounded behind; suture strongly keeled at the summit of the apical de- 

 clivity, the latter nearly straight, deep and not quite perpendicular in profile; 

 disk with feebly imijressed series of rather coarse, deep, moderately close-set 

 punctures, each enclosing a large rounded scale; intervals subequal, feebly 

 convex, generally equally so, but occasionally with the alternate intervals very 

 slightly more convex, having very short and unevenly distributed hairs in ad- 

 dition to the scaly vestiture. Abdomen densely scaly and pilose, the first
