340 SEEEICOESIA. 



Fulvous, the head in great part, the prothorax with two vittee on the disc, the 

 elytra with an interrupted ante-median fascia, the apical two-fifths, and the 

 suture anteriorly, black ; prothorax transverse, shining, foveate at the sides . venustus. 



1. Achrestus fulvovittatus. (Tab. XV. fig. 2, <$ .) 



Elongate, parallel, moderately broad, opaque ; deep black, the hind angles of the prothorax, and an elongate 

 patch on the outer part of the disc of the elytra at the base, extending to the humeri and inwards to 

 opposite the scutellum, rufous ; the antennae, legs, and under surface black, the knees and tarsal claws 

 rufous ; above densely clothed with rather long, coarse hairs, which are erect on the head and on the 

 base of the elytra and decumbent on the rest of the upper surface, the hairs fulvous along a broad stripe 

 on either side of the disc of the prothorax, extending from the hind angles to the apex, and continued on 

 to the head, and on the rufous patch at the base of the elytra, those on the other parts brownish-black ; 

 the under surface shining, sparsely cinereo-pubescent. Head very densely, finely punctate, the punctures 

 becoming much coarser towards the apex, deeply triangularly depressed in front ; the frontal carina very 

 prominent, rounded anteriorly ; antenna? densely punctured and pubescent, about one-half the length of 

 the body, strongly fiabellate from the third joint, the rami broadly flattened and rapidly increasing in 

 length outwards. Prothorax as long as broad, convex, the sides rounded from the middle forwards and 

 sinuate behind ; the hind angles strongly produced, divergent, blunt and slightly incurved at the tip, 

 carinate above ; the surface very densely and finely punctate throughout, deeply longitudinally sulcate in 

 the middle behind. Elytra about two and two-thirds the length of the prothorax, parallel to beyond the 

 middle, flattened on the disc, somewhat abruptly declivous at the base, bluntly rounded at the apex ; 

 coarsely and deeply punctate- striate, the interstices convex, densely, finely punctate. .Beneath somewhat 

 thickly, moderately finely punctate, the prosternum and propleurae very sparsely punctured. 



Length 11, breadth 3 millim. ( <5 •) 



Hab. Nicaragua, Chontales {E. M. Janson). 



One male example. Allied to A. lycidioides, Cand., from Cayenne, but differing 

 from that species in its much longer thorax, and in the strongly fiabellate antennae in 

 the male. 



2. Achrestus venustus. (Tab. XV. fig. 4, c? .) 



Elongate, parallel, rather narrow, shining ; the head black, fulvous in the middle in front ; the prothorax 

 fulvous, with two broad, narrowly separated, black vittae on the disc, which are dilated on the outer side 

 before the middle and narrowed behind ; the scutellum piceous ; the elytra fulvous, with the apical two- 

 fifths, and the suture rather broadly to a little beyond the basal third, violaceous-black, and a broad, 

 oblong, subquadrate patch on the outer part of the disc before the middle piceous ; the antennae and legs 

 black, the latter with the trochanters and tarsal claws rufo-testaceous ; the under surface in great part 

 black, the prosternum and the propleurae, a broad space along the middle of the latter excepted, flavo- 

 testaceous ; above thickly clothed with long, coarse, semi-erect hairs, which partake of the ground-colour, 

 beneath sparsely clothed with yellowish-cinereous hairs. Head sparsely, coarsely, irregularly punctate, 

 deeply transversely depressed in front ; the frontal carina very prominent, subtruncate anteriorly ; antennas 

 more than half the length of the body, strongly fiabellate from the third joint, the rami broadly flattened 

 and gradually increasing in length. Prothorax transverse ; the sides slightly flexuous, rounded in front ; 

 the hind angles strongly produced, moderately divergent, blunt and slightly incurved at the tip, finely 

 carinate above ; the surface sparsely, irregularly punctate, a broad space along the centre almost smooth, 

 deeply foveate at the sides before the middle, and with a median channel, which becomes very deep and 

 broad behind. Elytra about three and one-half times the length of the prothorax, parallel for three-fourths 

 of their length, broadly rounded at the apex, a little flattened on the disc ; coarsely and very deeply 

 punctate-striate ; the interstices narrow, strongly convex, thickly, minutely punctate. Beneath sparsely, 

 finely punctate, the propleurae with a few widely scattered punctures only.
