268 AMERICAN COLEOPTERA. 



C'oiiotrachelus iiivacleiisi n. s. — Robust, rufopiceous, clothed not very 

 densely with small narrow ochreous and broader white scales, each elytral inter- 

 val with a row of sliort erect setse. Beak slightly less than half the length of 

 the body, not striate, rather finely punctate. Antennje inserted at the middle of 

 the beak, first funicular joint subeqiial to the next two, second slightly shorter 

 than the third and fourth united, the third scarcely as long as the fourth. Front 

 with a small moderately deep fovea. Prothorax wider than long, subconical, 

 apical constriction evident but not strong; surface moderately densely not very 

 coarsely punctate, not at all carinate, vestiture ochreous at middle, white later- 

 ally. Elytra four-sevenths wider than the prothorax and three times as long, 

 sides parallel ; humeral angles right, abruptly rounded ; interspaces convex, the 

 alternate ones finely evenly carinate. Body beneath coarsely closely punctate, 

 vestiture sparse, consisting of very narrow whitish scale-like hairs on the abdo- 

 men, and of broader white scales on the sterna. Mesosternum protuberant in 

 front. Thighs scarcely annulated, the front and middle feebly toothed, the hind 

 ones more strongly and acutely so. Length 5 mm.; width 2.75 mm. 



Described from a single specimen taken by Mr. Knaus at El 

 Paso, Texas. It should be placed next to adspersus to which it is 

 quite similar in appearance; the latter, however, lacks the erect bris- 

 tles of the elytra, and the funicular joints are differently propor- 

 tioned, the third joint being much longer than the fourth ; the white 

 scales are also more obviously condensed in spots than in the present 

 .species, in which they show a tendency to become aggregated in 

 longitudinal vittse which alternate feebly with the ochreous scales. 



Acalles indi^ens n. sp.— Blackish-brown, clothed with dull yellowish 

 and brown scales, which are rather sparse, linear, and appressed on the pro- 

 thorax ; stouter, though about three times as long as wide, on the elytra, where 

 they are closely but not very densely placed ; in great part recumbent, but tend- 

 ing to become reclinate toward the sides and apex, especially on the more promi- 

 nent interspaces. Head and basal portion of the beak densely scaly, scales yel- 

 lowish on the occiput, dark brown on the front and beak; beak stout, densely 

 punctate, feebly carinate basally. Eyes small, flat, entirely lateral. Antennae 

 pale rufous, fiist Joint of funicle subequal in length to the next two together, 

 second joint about as long as the third and fourth united ; seventh as wide as 

 long, club ovate, widest a little beyond the middle. Prothorax nearly as long as 

 wide, broadly constricted in front, moderately rounded just before the middle, 

 thence convergent and nearly straight to base; surface densely evenly punctate, 

 median line not at all carinate or sulcate. Elytra rather broadly ovate, one-third 

 wider than the prothorax, and slightly less than twice as long; humeri not de- 

 fined ; strial punctures rather coarse, close set, the interspaces narrower than the 

 punctures, more or less convex. Scales obscurely mottled without well defined 

 spots or bauds, a small pale spot on the third interspace at the summit of the 

 declivity being most noticeable. Beneath very coarsely deeply punctate with 

 sparse linear scales. Legs dark brown, feebly annulate with pale scales. Length 

 3.4 mm.; width 1.7 mm. 



Cloudcroft. A single example sent by Mr. Wickham, who retains 

 the type. This species may best precede clavatus in our list.
