398 SEKEICOENIA. 



elongate ; the front is a little less convex than usual in Anchastus, but it is limited 

 anteriorly by a distinct carina ; the elytral interstices are closely and somewhat rugu- 

 losely punctured, so as to appear dull. The insect is unknown to Dr. Candeze. 



14. Anchastus forticornis. 



Oblong-oval, moderately convex, shining, thickly and rather coarsely pubescent ; pitchy-brown, the front of 

 the head, the basal and apical margins of the prothorax, the scutellum, the basal margin of the elytra, 

 the epipleurse, and the under surface obscure ferruginous, the antennae ferrugineo-testaceous, the legs 

 testaceous. Head closely punctured, convex, sharply margined in front ; antennae stout, half the length 

 of the body, feebly serrate, joints 3 and 4 equal, 2 very short. Prothorax a little broader than long, 

 parallel behind, gradually narrowing from about the basal third forwards; the hind angles strongly 

 produced, acute, bicarinate, the outer carina long and near the margin, the inner one shorter and oblique ; 

 the surface thickly and somewhat coarsely punctured. Elytra the width of the prothorax at the base, 

 arcuately narrowing from about the basal third, conjointly rounded at the apex ; rather coarsely punctate- 

 striate, the interstices feebly convex at the sides, flat on the disc, and somewhat roughly punctured. 

 Beneath closely, rather coarsely punctate ; prosternal sutures deeply channelled in front ; posterior coxal 

 plates broadly dilated inwards, and becoming exceedingly narrow outwards, the median portion acutely 

 triangularly produced and reaching as far as the first ventral suture. 



Length 5, breadth 1| millim. ( <3 .) 



Hab. Guatemala, Chaeoj in Vera Paz (Champion). 



One male specimen, found in the Polochic valley. In the form of the posterior 

 coxal plates this small species approaches the genus Physorhinus ; but differs from it in 

 having the sutures between the presternum and propleurse narrowly separated, the third 

 joint of the antennas as long as the fourth, the head shorter and more declivous, &c. 

 The antennae are stout and half the length of the body. 



15. Anchastus lateritius. 



Moderately long, rather depressed, shining, thickly pubescent ; reddish-brown, the prothorax with the base 

 broadly and indeterminately testaceous, the under surface ferruginous, the legs testaceous. Head closely 

 punctured, convex, sharply margined in front; antenna? slender, extending to a little beyond the hind 

 angles of the prothorax, joints 3 and 4 equal, 2 very short. Prothorax slightly broader than long, almost 

 parallel behind, gradually narrowing from about the basal third forwards ; the hind angles acute, strongly 

 produced, bicarinate, the outer carina long and near the margin, the inner one shorter and oblique ; the 

 surface thickly punctured. Elytra moderately long, as wide as the prothorax at the base, parallel to the 

 middle and narrowing thence to the apex, the apices conjointly rounded ; punctate-striate, the interstices 

 almost flat and somewhat sparsely punctured. Beneath closely punctured ; prosternal sutures deeply 

 channelled in front ; posterior coxal plates abruptly and subtriangularly dilated inwards to half the width 

 of the first ventral segment, becoming exceedingly narrow outwards. Legs slender. 



Length 4|, breadth 1-| millim. 



Hab. Guatemala, Mirandilia (Champion). 



One specimen, probably a female, found on the Pacific slope. This is another species 

 without near ally. It approaches A. tenuistriatus, but is smaller, narrower, and less 

 convex, the thorax is longer, the third joint of the antennas is as long as the fourth, 

 the elytral striae are distinctly punctured throughout, &c. A. difficilis, Fleut., from 

 Venezuela, somewhat resembles A, lateritius, but differs from it in the unicarinate hind 

 angles of the thorax, the shorter third joint of the antennas, &c.
