CNESINUS. 139 
line. Scutellum round, convex, punctured. Elytra a little wider than the prothorax, and nearly twice 
as long, separately rounded and crenate at base, the sides subparallel, slightly narrowed towards the 
apex; strie rather fine, punctured, interstices flat and rather wide, very finely rugulose and multipunctate, 
with thin, coarse, decumbent pubescence and a median row each of stronger erect sete ; declivity oblique, 
impressed in middle, more shining, with feebler striz and less pubescence. Apical process of anterior 
tibize long, its terminal spines short. 
Hab. Guatemaa, El Tumbador (Champion). 
But one specimen of this species was taken. It is a distinct form, peculiar in the 
coarse chaffy-looking hairs. 
6. Cnesinus strigicollis.

Through the kindness of Dr. Horn, I have been enabled to compare an authentic 
example of Leconte’s species with Chapuis’s type. In view of the close resemblance 
between certain species of Cnesinus the identification previously made required confirma- 
tion. Neither writer has thought it necessary to note the difference which exists 
between the two kinds of elytral hairs, but the sete are not so conspicuous as usual. 
C. gibbus, Chap., from Venezuela, is a nearly-allied form, represented in Chapuis’s 
collection by a single example in poor condition. I have not been able to refer other 
specimens of Cnesinus to this species. 
7. Cnesinus setulosus, sp. n. 
Oblongus, subcylindricus, brunneus, capite nigro, flavo-pubescens; prothorace subquadrato, anterius angus- 
tato, dense strigoso-punctato et versus apicem parce squamoso ; elytris punctato-striatis, interstitiis planis 
breviter squamose pilosis, per totum longius uniseriatim setosis. 
Long. 2 millim. 
Oblong, cylindrical, brown. Head black, finely reticulate and sparsely punctured ; rostrum short, pubescent 
over the mouth and at the sides of the eyes, which are moderately approximated; antenne red-brown. 
Prothorax equal in length and breadth, bisinuate at base, its hind angles rectangular, the sides parallel 
to before the middle, thence subcircularly rounded to apex; surface dull, with thin decumbent pubescence 
and a few pale scales towards apex and at sides, with very close strigose punctuation, the strige not 
long, the median line obsolete. Scutellum oval, not impressed. Elytra as wide as the prothorax and 
one-half longer, parallel-sided, the apex circularly rounded; surface cylindrical, strongly and obliquely 
declivous and convex at apex, punctate-striate, the punctures inconspicuous, interstices flat, with a close 
covering of short subsquamous hairs, denser towards apex, and a median row of longer, erect, flattened 
sete. Underside brown, punctured and shortly pubescent. Legs piceo-ferruginous. 
Hab. Paxama, Tolé, San Lorenzo (Champion). 
Three examples. This species, if in good condition, may be easily recognized by the 
pubescence, which is denser than in any other Cnesinus known to me; but when 
rubbed there is very little to distinguish it from C. strigicollis except its smaller size
