ATHOTJS. 461 



8. Athous angusticollis. 



d . Very elongate, shining, somewhat sparsely pubescent ; piceous, paler beneath, the elytra brown or pitchy- 

 brown, the antennas, legs, and epipleurse reddish-brown. Head closely, rather finely punctate, very deeply 

 triangularly excavate in front ; the front prominent, broadly truncate at the apex ; the eyes large ; 

 antennae moderately stout, serrate, extending to about the basal fifth of the elytra. Prothorax considerably 

 longer than broad, subparallel, slightly sinuate at the sides behind ; the hind angles divergent, not much 

 produced, rather obtuse, and finely carinate ; the surface closely, moderately finely punctate, the 

 punctuation becoming more crowded and umbilicate towards the sides and base, the disc transversely 

 flattened or depressed in the middle at the apex and feebly canaliculate behind. Elytra three times the 

 length of the prothorax, and much wider than it, flattened on the disc, gradually narrowing from the 

 middle to the apex, the apices rounded ; punctate-striate, the interstices moderately convex and thickly 

 punctured. Beneath closely punctured, the punctures on the propleurse coarse and umbilicate. Tarsi 

 simple. 



Length 10f-12, breadth 2§-3 millim. 



Hah. Mexico, Pinos Altos in Chihuahua, Rio Mescales (Buchan- Hepburn). 



Two examples. In its long narrow thorax, deeply triangularly excavate front, simple 

 tarsi, &c, this insect approaches the North-American A. ferruginosus, Eschsch., and 

 A. cribratus, Lee, bat differs from both of them in having the thorax more finely 

 punctured, with the hind angles finely carinate. The elytral sculpture resembles that 

 of A. ferruginosus, except that the striae are not so coarsely punctured. 



9. Athous funestus. (Tab. XX. fig. 15, <? .) 



(5 . Elongate, depressed, subopaque ; black or pitchy-black, the legs piceous, the claws testaceous ; somewhat 

 thickly clothed with long, decumbent, fuscous hairs. Head densely, coarsely punctate, deeply excavate 

 in front ; the front prominent, broadly truncate at the apex ; the eyes moderately large ; antennae rather 

 short, extending to a little beyond the humeri, the joints from the third dilated and strongly serrate, 

 3 as long as 4. Prothorax slightly longer than broad, gradually narrowing from the base, the sides 

 almost straight, feebly sinuate behind ; the hind angles short, obtuse, slightly divergent, and feebly 

 carinate, the carina placed near the margin and not extending to the tip ; the surface densely and rather 

 coarsely umbilicate-punctate, the punctuation becoming a little more diffuse on the middle of the disc in 

 front. Elytra three times the length of the prothorax, and considerably wider than it, subparallel to 

 the middle ; finely punctate-striate, the interstices flat, transversely rugulose, and thickly punctured. 

 Beneath closely punctured. Tarsi simple, the basal joint of the hind pair about as long as the following 

 three joints united. 



Length 10-10;*, breadth 2|-3 millim. 



Hah. Mexico, Ciudad in Durango (Forrer). 



Three examples, all males. This species somewhat resembles A. scissus, Lee, from 

 California ; but it is more depressed, the thorax is straighter at the sides and gradually 

 narrowed from the base, the elytra are much more finely punctate-striate, and the third 

 tarsal joint is simple. 



10. AtllOUS Carinicollis. (Tab. XX. figg. 16, <$ ; 16 a, prothorax.) 



Elongate, rather depressed, subopaque, black or pitchy-black, the legs piceous, with the tarsi partly or entirely 

 testaceous ; clothed with fine, fuscous pubescence. Head densely and coarsely umbilicate-punctate ; the 

 front concave, prominent, deeply emarginate in the middle ; the eyes moderately large ; antennas slender, 

 rather more than half the length of the body in the male, much shorter in the female, joint 3 as long as 4.
