CNESINUS. 14] 
9. Cnesinus gracilis, sp. n. 
Elongatus, cylindricus, sat nitidus, subglaber, niger, antennis pedibusque piceis ; prothorace longiore quam 
‘latiore, dense subtiliter reticulato et punctis oblongis notato ; elytris ad apicem convexe declivibus, sub- 
tiliter punctato-striatis, interstitiis planis irregulariter seriatim punctatis, ad basin rugulosis, in declivitate 
angustatis, convexis et tuberculis setigeris seriatis ornatis. 
Long. 2:2 millim. 
Elongate, cylindrical, black. Head closely reticulate and finely punctured, scarcely rostrate, impressed and 
pubescent over mouth; eyes not approximate. Antenne ferruginous-brown, the clubinfuscate. Prothorax 
a little longer than broad, bisinuate at base, the sides parallel to before middle, thence rounded to apex ; 
surface cylindrical, anteriorly convex, subsericeous, minutely reticulate, and with the apical border alone 
shining, moderately closely covered with fine oblong punctures, not confluent nor strigose. Scutellum 
rounded, feebly punctured, not depressed. Elytra not wider than the prothorax and less than twice as 
long, their basal margins feebly rounded, not elevated, the shoulders not prominent, the sides subparallel, 
slightly narrowed behind, apex rounded ; surface cylindrical, strongly but rather obliquely declivous at 
apex, finely punctate-striate, the punctures small, the strie impressed at apex, sutural stria deeper 
throughout, interstices flat, with delicate transverse wrinkles, rather stronger at base, and irregular 
single series of minute punctures, narrowed and convex on the declivity and set with single series of short 
semi-erect pale bristles. Underside black, punctured, nearly glabrous. Legs piceous, with tarsi lighter ; 
tibial teeth weak. 
Hab. Panama, Volcan de Chiriqui (Champion). 
One example. I have seen three or four more from refuse tobacco *. 
10. Cnesinus pullus, sp. n. 
Oblongus, subnitidus, glaber, niger, antennis preter clavam genubus et tarsis ferrugineis ; prothorace paullo 
longiore quam latiore, dense subtiliter strigoso-punctato ; elytris haud profunde punctato-striatis, inter- 
stitiis planis rugulis transversis notatis, in declivitateconvexis, haud setosis. 
Long. 1:7 millim. 
* The following species may succeed C. gracilis :— 
Cnesinus teres, sp. n. 
Elongatus, subcylindricus, subopacus, niger, elytris nonnunquam nigro-piceis, apice dilutiore, antennis pedi- 
busque rufescentibus ; prothorace oblongo, strigoso-punctato ; elytris striis profundis, posterius latioribus 
exaratis, interstitiis planis, dense reticulato-punctatis, declivitate impressa, squamis cinereis ornata. 
Long. 2 millim. 
About the size of C. gracilis, but less elongate; black, the anterior margin of the prothorax and the elytra, 
especially at the apex, obscure piceous ; antenne and legs in part reddish. Head (¢) with a smooth 
frontal elevation, very shining and distinctly iridescent ; front( 2 ) dull, slightly pubescent, with a shining 
median line towards the mouth ; eyes not approximate. Prothorax longer than broad, subparallel behind 
the anterior third; with close, strigose, oblong punctures, sparser behind towards the sides. LElytra 
wider at base than the prothorax and two-thirds longer, cylindrical and gradually rounded at apex ; with 
deep narrow incised punctured strizx, slightly widened posteriorly ; interstices flat, glabrous before the 
declivity, dull, with close, fine sculpture of intermingled punctures and wrinkles ; declivity squamous, with 
close, short, erect, cinereous scales, and impressed in the middle along the suture, the second interstice 
narrowed towards apex. 
Hab. Venezveua (Moritz). 
A distinct species, of which I have seen five specimens. Four, takea by Dr. Moritz, are from the Vienna 
Museum ; the other stands in the Chapuis Collection under the MS. name Nemobius [sic] teres. 
A curious feature of this species is the frontal iridescence in the male ; it is noticeable, though less strongly, 
in C. pullus and in some Hewacoli.
