394 SEEEICOENIA. 



punctured. Beneath closely, the prosternum and propleurse sparsely, punctured; prosternal sutures not 

 channelled in front. 

 Length 8§-10, breadth 2§-3| millim. ( $ .) 



Hah. Nicakagua, Chontales (Belt). 



Two examples, one of which is a female, the other perhaps a male. This insect 

 approaches A. (Monelasmus) augusti, Cand., but it is very differently coloured, and has 

 the front a little more raised anteriorly and more distinctly separated from the anterior 

 margin of the head. 



7. Anchastus melaimrus. (Tab. XVII. figg. 20, $ ; 20 «, hind angles of 

 prothorax.) 



Elongate-oval, moderately convex, feebly shining ; luteous, the base of the elytra a little paler, the antennae, 

 the scutellum, a large patch at the apex of the elytra, the under surface, the propleurse excepted, and the 

 legs, deep black ; above and beneath thickly pubescent, the pubescence on the upper surface partaking of 

 the ground-colour, that on the under surface, except at the sides of the abdomen, fulvous. Head thickly 

 punctured, convex, declivous in front ; the front separated from the anterior margin by a narrow space, 

 the carina indistinct in the middle ; antennas about reaching the hind angles of the prothorax in the male, 

 a little shorter in the female, the joints from the third moderately widened and serrate, 3 and 4 equal, 

 2 very short. Prothorax longitudinally convex, as long as broad, narrowing from the base forwards, the 

 sides rounded anteriorly ; the hind angles strongly, acutely produced, not divergent, obliquely unicarinate ; 

 the surface very finely and closely punctured. Elytra nearly as wide as the prothorax at the base, 

 narrowing from the basal third, the apices separately rounded; rather coarsely punctate-striate, the 

 interstices fiat on the disc, feebly convex at the sides, closely, very finely punctate. Beneath closely, 

 finely punctate, the prosternum more sparsely punctured ; prosternal sutures not channelled in 

 front. 



Length 8-10, breadth 2|-3| millim. ( <$ $ .) 



Hab. Panama, Bugaba (Champion). 



Two specimens. Allied to A. diversus, but differing from it in the more coarsely 

 punctate-striate elytra, the black patch on which is confined to the apical third, and the 

 less parallel thorax. 



8. Anchastus seminiger. (Tab. XVII. fig. 21.) 



Elongate-oval, moderately convex, rather shining ; deep black, the head and prothorax rufo- or sanguineo- 

 testaceous, the elytra with the third interstice at the base and a spot at the shoulders beneath, the pro- 

 and mesosternum, the labrum, and palpi testaceous, the ventral segments 1-4, except at the sides, and 

 the propleurse rufo-testaceous, the antennae and legs, the base of the femora excepted, deep black ; above 

 and beneath thickly sericeo-pubescent, the pubescence on the upper surface partaking of the ground-colour, 

 that on the under surface in great part fulvous. Head closely, finely punctate, convex, declivous in front ; 

 the front separated from the anterior margin by a narrow space, the carina obsolete in the middle ; antennas 

 extending a little beyond the hind angles of the prothorax, the joints from the third broadly dilated and 

 serrate, 3 and 4 equal in length, 2 very small. Prothorax about as long as broad, gradually and arcu- 

 ately narrowing from the base forwards ; the hind angles strongly produced behind, not divergent, rather 

 obtuse at the tip, feebly and obliquely unicarinate ; the surface closely, very finely punctate, canaliculate 

 behind. Elytra slightly narrower than the prothorax, gradually narrowing from a little below the 

 shoulders, flattened on the disc, separately rounded at the apex ; rather coarsely punctate-striate, the 

 punctures of each stria very distinct, the interstices flat and closely, very finely punctate. Beneath
