364 . HETEROMERA. 
Elytra long or moderately long, more or less coarsely striate-punctate, the punctures 
often transverse and closely approximate ; upper surface greenish-eneous, violaceous, 
or cyaneous, the elytra rarely nigro-eneous, the latter (except in vars. of S. varians 
and §. misantle) more or less margined or striped with red, reddish-testaceous, or 
testaceous; size moderate or small. 
a. Elytra long, usually more or less cylindrical, the lateral margins and 
base reddish-testaceous or testaceous. 
+ Eyes small or moderate, more or less widely separated.

Strongylium cruentatum, Mik. Monogr. p. 227; Act. Soc. Fenn. vii. part 1, p. 335°. 
Hab. Mexico }, Cordova, Santecomapan (Sal/é). 
S. cruentatum differs from its allies in having the punctures of the elytral series fine 
and shallow on the disc, the punctures not transverse, the interstices flat on the disc 
and broad and shining; and also by the very stout antenne. 
40, Strongylium nitidiceps. (Tab. XV. fig. 20, 2 .) 
Elongate, subcylindrical, greenish-zeneous more or less suffused with cyaneous or violaceous, shining. Head broad, 
comparatively very smooth, the antennary orbits somewhat dilated and very prominent, very sparingly 
and finely punctured, longitudinally impressed between the eyes, very shining, the anterior half much 
suffused with golden, the oral organs (the mandibles excepted) testaceous; eyes comparatively small, 
rather convex, very widely separated in both sexes; antenne slender, rather short (not passing very far 
beyond the base of the elytra in either sex), very little longer in the male than in the female, gradually 
widening outwardly, joints 3 and 4 long, subequal, the penultimate joints much longer than broad, the 
apical joint rather longer than the tenth and ovate, the basal joint of a greenish-golden tint, the rest 
entirely testaceous; prothorax as long as or rather longer than broad, subcylindrical, the sides (at 
least in one example) very obsoletely margined behind though not visibly so from above, a little rounded 
about the middle, slightly sinuate behind, and gradually narrowing in front, the apex straight and feebly 
margined (the margin not grooved within), the base slightly sinuous, the basal foves deep, the anterior 
angles obtuse, the hind angles subrectangular, the disc broadly flattened in the middle behind and with a 
shallow (or deep) rounded fovea on each side about the middle, the surface finely or moderately finely, 
very sparingly, subequally punctured; scutellum triangular, smooth, greenish-eneous; elytra long, sub- 
parallel in their basal half, moderately convex, rather finely striate-punctate, the punctures transverse in 
shape, shallow, approximate, and gradually becoming almost or quite obsolete towards the apex, the 
interstices flat, feebly convex at the apex only, and very minutely and sparingly punctured, the apices a 
little produced, somewhat compressed laterally, the first or sutural stria deeply impressed behind, the 
surface duller and less shining than that of the prothorax, red or reddish-testaceous, with a very broad 
obscure bluish- or greenish-eneous sutural stripe extending from a little below the base to the apex; 
beneath greenish-sneous, very sparingly punctured, indistinctly pubescent; legs comparatively rather 
short, the femora almost smooth, violaceous, the tibie rather short, roughly punctured, greenish-sneous, 
the tarsi piceous, the first joint of the posterior tarsi rather longer than the apical one; the anterior 
tibiee in the male very short and but little curved, scarcely differing from those of the female. 
Length 11-13 millim.; breadth 33-4 millim. (¢ 9.)
