STRONGYLIUM. 305 
Elytra very long and attenuate, finely striate-punctate, here and there depressed along 
the suture, the apices obliquely truncate; antenne short, subclavate; eyes small; 
upper surface bright bronze. 
23. Strongylium langurioides. (Tab. XV. fig. 12,2.) 
Very elongate, narrow, moderately convex, bright bronze, with a slight golden tint. Head coarsely and rather 
closely punctured, the intraocular space indistinctly impressed in the middle; eyes rather small, a little 
convex, widely separated ; antenns( ? ) short, scarcely passing the base of the prothorax, subclavate, very 
greatly widened outwardly, joints 3 and 4 comparatively short, subequal, 5-7 subtriangular, each much 
wider than the preceding, 8-10 subcyathiform, the width of 7, transverse, 9 and 10 very strongly so, 11 
much narrower but longer than 10, short ovate, 1-4 reddish-testaceous, 1 tinged with cyaneous, 5-10 dull 
piceous, 11 in greater part pale testaceous ; prothorax cylindrical, as long as broad, the sides almost straight, 
very slightly narrowing in front, the base a little sinuate and strongly margined, the apex straight, the 
anterior angles rounded, the hind angles rectangular, the basal fovee deep, the disc with a rounded 
impression on each side behind the middle and a little flattened before the base, the surface sparingly and 
coarsely punctured ; scutellum triangular, smooth; elytra very long, attenuate, gradually narrowing from 
the base, the apices a little produced and obliquely truncate, shallowly but somewhat coarsely striate- 
punctate, the punctures becoming almost obsolete at the apex, the interstices smooth and flat throughout, 
the disc a little flattened and with a row of three large shallow oblong impressions (the first some distance 
below the base), beyond which are one or two irregular (perhaps accidental) excavations, on either side 
near the suture; beneath greenish-zneous, the sides, the ventral segments at the base, and the coxa, 
suffused with reddish-brown, glabrous; legs rather long and slender, the femora smooth, eneous, the 
basal half of the femora and the tibiz in great part reddish, the tarsi bluish-black, the first joint of the 
posterior tarsi shorter than the apical joint. 
Length 103 millim.; breadth 24 millim. ( 2.) 
Hab. Nicaraaua, Chontales (Belt). 
A single example. This remarkable species bears a very close resemblance to a 
Languria, even to the truncate apices of the elytra and the clavate antenne. The 
elytra have a longitudinal series of large shallow depressions on each side of the 
suture. 
Elytra finely striate-punctate, foveolate-striate at the sides towards the base, the punctures 
almost obsolete at the apex; upper surface obscure greenish-eneous, the elytra 
cupreo-eneous, shining ; form cylindrical.

Unknown to me. Apparently an ally of the Brazilian S. aurichalceum (Germ.).
