224 MEMOIRS ON THE COLEOPTERA 



preceding joint and is much more gradually pointed than that of 

 the labial palpi. The single discal puncture of the elytra is ex- 

 tremely minute, the lateral line of foveae broadly interrupted 

 medially, the striae deep and abrupt and the scutellar stria short 

 but distinct, extending from an unusually strong deep annulate 

 fovea. The antennae and hind tarsi are distinctly short when 

 compared with most of the American types, and I have at present 

 scarcely any doubt of the generic distinctness of all the latter as 

 denned in the table. 



GONIOCELLUS n. gen.- The body here is somewhat ventricose 

 as in Bradycelhis, but the hind body is oblong and parallel and 

 not so oblong-oval and with rather strongly arcuate sides as it is 

 in that genus, and the prothorax is of an entirely different shape, 

 being sinuously narrowed basally, with right and very sharply 

 defined basal angles. The mental emargination is similarly very 

 shallow and the tooth large and very acutely triangular. The 

 palpi and maxillary lobe are also nearly as in Bradycellus, except 

 that the last joint of the palpi is very much more gradually pointed 

 and the outer lobe of the maxilla less inflated basally, longer and 

 much more gradually drawn out into a fine point apically. The 

 antennae are more slender and have but two glabrous joints, the 

 third being nearly like the fourth, though notably more elongate. 

 The elytral striae are deeply impressed, sulciform, the scutellar 

 wholly wanting, although the fovea is well developed; the discal 

 puncture is strong and the lateral line of foveae very widely inter- 

 rupted. The hind tarsi are very slender and more or less notably 

 long. There are two species before me, which may be described 

 as follows, bifossifrons being the type : 



*G. bifossifrons n. sp. Convex, strongly shining, blackish-piceous, 

 the thoracic margins somewhat paler, the head also not so dark as the 

 elytra; legs honey-yellow; head three-fourths as wide as the prothorax, 

 with well developed and prominent eyes, the frontal foveae very deep, 

 oblique and attaining the eyes; antennae long and slender, rather more 

 than half as long as the body, brown, the basal joint honey-yellow; pro- 

 thorax not a third wider than long, the sides rounded anteriorly, oblique 

 and broadly sinuate basally, the angles right and extremely sharp but not 

 everted; base and apex equal, the latter broadly sinuato-truncate, with 

 sharply marked but not prominent angles; surface smooth, finely reflexed 

 along the sides, feebly impressed latero-basally and with strong close-set 

 punctures extending to the sides, obsolescent medially, the stria fine but 

 strong and entire; elytra two-fifths longer than wide, three-fourths wider
