41 4 SEKKICOENTA. 



the antennae and legs flavo-testaceous. Head thickly and somewhat coarsely punctate, with a short, 

 smooth, longitudinal carina on the vertex ; antennae slender, feebly serrate, about half the length of the body 

 in the male, shorter in the female, joints 2 and 3 subequal in length, 4-11 moderately elongate. Pro- 

 thorax very convex, nearly as long as broad, about equal in width at the base and apex, rounded at the 

 sides, the latter strongly sinuate before the base ; the anterior angles acute and rather prominent ; the 

 hind angles acute, divergent, and unicarinate, the carina very short ; the surface thickly punctured, the 

 punctures finer than those on the head, canaliculate down the middle from the base to the apex. Elytra 

 about two and one-half times the length of, and much wider than, the prothorax, subparallel to the 

 middle, and arcuately narrowing thence to the apex ; closely, confusedly punctate, without trace of striae. 

 Beneath closely and finely, the pro- and metasternum very sparsely, punctate.

Hah. Mexico, Teapa [Pilate, in coll. Janson) ; Guatemala, Las Mercedes, Cerro 

 Zunil, Zapote (Champion); Panama, Bugaba, Tole (Champion). 



Eleven examples, varying considerably in the extent of the dark markings on the 

 thorax and elytra. The median vitta on the thorax is well-defined in some specimens 

 and obliterated in others ; the basal patch on the elytra is sometimes obsolete, and the 

 median fascia reduced to a spot on the disc. In one specimen the basal patch is 

 connected with the median fascia at the suture and at the sides, so as to enclose a large 

 spot of the ground-colour on each elytron. A specimen from Zapote is figured. 



The following genus is of doubtful position. It will probably have to be included 

 in the group Agrypnini. 



AGRYPNELLA. 



Head very deeply sunk into the prothorax ; the front broad, flattened, and extending beyond the labrum, 

 separated from the anterior margin of the head ; apical joint of the maxillary palpi moderately stout, 

 obliquely truncate at the tip ; antennae short, the basal joint very stout, the other joints rather slender 

 and feebly serrate, 2 longer than 3 ; prothorax trisinuate at the base, truncate in the middle in front, 

 the anterior angles deflexed, the hind angles obliquely truncate and not carinate, the sides somewhat 

 explanate and abruptly separated from the propleurae ; scutellum large, broad-oval ; elytra rather short, 

 with the base deeply and obliquely sinuate-emarginate on either side for the reception of the hind angles 

 of the prothorax ; prosternum moderately broad in front, with a broad, prominent chin-piece, which is 

 limited behind by a transverse groove, the sutures single and obliquely converging, the prosternal process 

 moderately long, subangular at the tip ; propleurae with a sharp carina extending almost parallel with the 

 margin from opposite the middle of the lower portion of the eye to the base, and with a space along the 

 inner side of the carina from the apex to the middle slightly hollowed for the reception of a portion of the 

 antenna ; mesosternum abruptly declivous, notched in the middle in front, the cavity extending into the 

 metasternum ; middle coxae widely separated ; posterior coxal plates very broadly and abruptly widened 

 at the middle, becoming exceedingly narrow outwards ; tarsi filiform, simple, the basal joint not so long 

 as the following two joints united, the claws simple ; vestiture of the body squamiform. 



This genus includes two small species — Cryptohypnus squamifer, Cand., which is 

 widely distributed in Tropical America, including the Antilles, and the insect from the 

 Amazons described below *. It possesses very remarkable characters, some of which 



* Agrypnella eburnea. 



Apparently fuscous, completely covered with whitish scales ; a large spot on the disc of the prothorax at the 

 base, excised in front and behind, an oblique angulate mark on the outer part of the disc of each elytron
