BEACHYSPHENUS. 95 



not very strong. Elytra broad, very even, with fine punctured strise, the interstices 

 quite flat and even, the series evanescent towards the apex. Underside quite smooth 

 and even. The prosternum has a broad intercoxal process, with a minute impressed 

 puncture on each side, the front not much compressed and terminating in a point which 

 is but little produced or elevated. The central part of the mesosternum is transverse ; 

 the metasternal lines are very distinct, terminating before reaching the episterna, the 

 latter with the epimera broad and smooth. The abdomen is not quite so even as the 

 rest of the underside; the segments are vaguely impressed on each side, and these 

 impressions are sometimes infuscate. The legs are black, including the trochanters, 

 but the coxae are entirely of the waxy-yellow colour of the body, and the claws are red. 

 Eight specimens of this very neat though plainly-coloured species were obtained, two 

 of them at elevations between 4000 and 6000 feet, the others at lower altitudes on the 

 Volcan de Chiriqui. 



7. Brachysphenus exiguenotatus. 



Ovatus, convexus, brunneo-castaneus, antennis (articulis duobus basalibus exceptis) nigris ; elytris postice 

 subacuminatis, seriatim punctnlatis, singulis puncto basali obsolescente alteroque mediano, marginem 

 lateralem versus, interdum geminato, nigris ; tibiarum basi tarsisque fuscis. Long. 7-8 millim. 



Hah. Nicaragua (Salle); Panama, Volcan de Chiriqui (Champion). 



Of the form and size of B. spadiceus, or nearly so ; very polished and shining ; the 

 thorax very short and transverse, its disc convex and very smooth, its sides narrowing 

 from the base and very faintly rounded, the base gently bisinuate and with a few 

 obsolete punctures along the margin, the median lobe feeble. Scutellum red. Elytra 

 very convex, ovate-cordate, slightly gibbous ; each with seven rows of rather distinct 

 punctures, vanishing towards the apex, and each with a black dot, made up of two or 

 three black punctures, at the base of the third and fourth striae, and a similar but often 

 double dot on the sixth and seventh strise near the middle. Prosternum strongly 

 compressed and pointed in front. Margins of the epipleurse blackish ; the base of the 

 tibise infuscate. 



Two specimens from Nicaragua and one from the Volcan de Chiriqui. 



8. Brachysphenus brevicolHs. 



Oblongo-ovatus, lucide ferrugineus, nitidus, glabratus; antennis (articulis duobus primis exceptis), scutello 

 tibiisque basi nigris, tarsis infuscatis. Long. 5|-7 millim. 



Hah. Panama, Bugaba (Champion). 



Head and thorax glabrous, shining, pale rusty-yellow ; the latter very short, and with 

 the disc convex, the sides strongly contracted to the front angles and very evidently 

 rounded, the front angles acute and prominent, the base bisinuate and with a well- 

 defined median lobe. Elytra almost smooth, but with striae formed of fuscous punc- 

 tures visible beneath the surface and only minutely impressed above. Scutellum black.
