AMERICAN COLEOPTERA. 53 



ANCHOIVODERUS Reiche. 

 A, quadrinotatus n. sp. — Piceous, sparsely pubescent, legs, palpi and 

 antennae at base testaceous, elytra each with two reddish spots, one subhumeral, 

 the other subapical and larger. Head moderately shining, front slightly longi- 

 tudinally impressed on each side, vertex and occiput sparsely punctured. 

 Antennae piceous at base, brownish externally. Thorax cordiform, not wider 

 than the head, as wide as long, base narrower than apex, sides in front moder- 

 ately arcuate, gradually narrowing to base and feebly sinuate in front of hind 

 angles which are rectangular but not prominent, median line finely impressed, 

 surface sparsely punctured, sparsely clothed with short, erect, yellowish pubes- 

 cence. Elytra oval, sides feebly arcuate, surface striate, striae serrately punc- 

 tured, intervals slightly convex S[)arsely punctulate and pubescent, piceous 

 and with two rufous spots, one near the humeri small, another near the tip, 

 larger and round. Body beneath piceous sparsely pubescent. Prothoracic 

 side pieces nearly smooth, abdomen moderately densely punctured. Length 

 .28 inch ; 7 mm. 



Two specituens from Texas. 



Anchonitihruii differs from Lachnophorus in the form of the palpi 

 which have the terminal joiut feebly fusiform ia the first and ovoid 

 terminating in an acute point in the latter genus. The anterior tarsi 

 of male have three joints feebly dilated. 



COTAIiPA Burm. 

 C flaTida n. sp. — Body beneath and tarsi piceous black, upper surface 

 legs and pygidium pale yellow. Clypeus transverse, slightly narrower in front, 

 apex feeldy arcuate, angles broadly rounded. Front and clypeus moderately 

 densely but finely rugulose. Thorax very sparsely punctured on the disc, 

 moderately densely and finely ruguloso-punctate at the sides. Elytra sculp- 

 tured as in lanigera, distinctly subangulate at the sides, more strongly in the 

 9 which has also a distinct tubercle at the angulation. Pygidium yellowish, 

 finely scabrous, smoother in the male. Legs yellowish tarsi pitchy black, body 

 beneath sparsely pubescent, less densely than in lanigera. Length .90 — 1.00 

 inch ; 23 — 25 mm. 



This species is closely allied to lam'yera, which it resembles in form 

 and color although without any of the metallic lustre of surface. It 

 very distinctly differs in the thorax being rugulose at the sides, the 

 clypeus more narrowed in front and the under side of body and tarsi 

 pitchy black and the surface much less pubescent. The under sur- 

 face is very much less distinctly punctured. The greatest describabie 

 difference is between the females. In the present species the elytra 

 are very distinctly subangulate in front of middle and a well marked 

 tubercle in the angulation. There is scarcely any trace of either 

 angulation or tubercle in lanijera. 



I have examined about twenty specimens of this species collected 

 at St. George, Utah, by Dr. Edw. Palmer.
