in 8. permodicum), the punctures much coarser and deeper, and less approximate, though fine, shallow, and 
more scattered at the apex ; the fifth ventral segment more deeply impressed in the middle behind in the 
male; the rest much as in S. permodicum. 
Length 6% millim.; breadth 2 millim. (<¢.) 
Hab. Nicaraaua, Chontales (Janson). 
A single example. This insect is almost intermediate between S. permodicum and 
S. gregarium, but quite distinct from either. The stouter antenne (3), the larger 
and more approximate eyes, the more coarsely and less closely punctured and less 
transverse thorax, the much longer elytra, and the more coarsely and more closely 
punctured under surface separate it from S. gregarium. 
Elytra rather short, very coarsely striate-punctate, the alternate interstices narrowly 
costate ; eyes large, approvimate ; upper surface greenish-ceneous, the elytra testa- 
ceous, with a subapical patch on each and the suture fusco-violaceous ; size small. 
61. Strongylium carinipenne. (Tab. XVI. fig. 13, 3.) 
Moderately elongate, slightly convex, dull greenish-neous. Head in front bright seneous and closely and rather 
coarsely punctured, behind dull and very coarsely and rugulosely punctured, shallowly impressed between 
the eyes, the latter large and approximate ; antenne ( ¢ ) moderately long, rather stout, joint 4 about as 
long as but broader than 3, subtriangular, joints 5-10 nearly equal in length, widening very slightly 
outwardly, each nearly as broad at the base as at the apex, all longer than broad, 11 oblong-ovate, longer 
than 10, 1-3 greenish-eneous, the rest dull black ; prothorax subquadrate, strongly transverse, the sides 
immarginate, very feebly rounded, equally (but very slightly) narrowed before and behind, and armed in 
the middle with a sharp tooth, the base and apex nearly straight, the anterior angles rounded, the hind 
angles rectangular, the basal fovese moderately deep, the disc almost unimpressed, the entire surface rather 
uneven and (like the vertex) very coarsely and rugulosely but somewhat shallowly punctured ; scutellum 
triangular, smooth, very shining, metallic green; elytra moderately long, subparallel to beyond the middle, 
a little depressed on the disc, very coarsely striate-punctate throughout, the punctures transverse in shape 
and approximate, and very little finer at the apex, the interstices smooth, narrow, the third, fifth, and 
seventh costate from the base to the apex, the others a little raised at the sides and apex, the smooth sutural 
space broad, the surface shining, testaceous, the suture and an ill-defined patch on the disc of each towards 
the apex fusco-violaceous ; beneath almost glabrous, bright greenish-zneous, sparingly but rather coarsely 
punctured, the sides of the metasternum and the flanks of the prothorax very coarsely so; legs moderately 
long, very coarsely punctured, bright greenish-zeneous, the coxe, the femora towards the base, and the 
tibie in part obscurely reddish, the tarsi piceous; the first joint of the posterior tarsi shorter than the 
apical joint; the tibie almost straight, and the fifth ventral segment shallowly transversely impressed in 
the middle behind, in the male. 
Length 7% millim.; breadth 23 millim. (<¢.) 
Hab. Panama, Bugaba (Champion). 
This is a small species somewhat resembling S. armatum: it differs in the thorax 
being duller and much more closely and rugulosely punctured ; the elytra shorter, with 
the alternate interstices costate, the surface testaceous, with the suture and a subapical 
patch on the disc of each fusco-violaceous, the sutural space broad and smooth (as in 
S. permodicum, &c.); the eyes are large and approximate as in S. armatum. SS. cari- 
nipenne, except in the colour of the elytra, also approaches several South-American 
epecies described by Maklin, but does not agree with any of them.
