352 HETEROMERA. 
crowded at the sides; scutellum triangular, sparingly punctured; elytra rather short, somewhat depressed 
on the disc, widest at the base, the sides nearly straight to beyond the middle, the surface from the base 
to the apex with irregular and much interrupted rows of very coarse and deep excavations, the excavations 
punctiform at the extreme base and there arranged in more regular rows, the interstices strongly and 
irregularly raised towards the base and sides and here and there transversely or obliquely confluent, the 
third forming an elevated ridge near the base, smooth, the apices slightly pointed ; beneath distinctly 
pubescent, shining, golden-bronze, the sides here and there tinted with greenish, somewhat finely and 
sparingly punctured, the flanks of the prothorax exceedingly coarsely and the sides of the metasternum 
coarsely and confluently so; legs stout, rather short, the femora very coarsely, the tibiee roughly and more 
finely, punctured, brassy-cupreous, the basal half of the tibia more or less red, the tarsi golden-green, the 
first joint of the posterior tarsi much shorter than the apical joint. 
Length 113 millim.; breadth 4 milim. ( 2.) 
Hab. Panama, Volcan de Chiriqui (Champion). 
One example. This species closely resembles S. variicorne in the sculpture of the 
elytra; but is readily separated by the broader shape, much stouter legs, very coarsely 
punctured femora, broader and shorter thorax (the sides of which are much more 
rounded), the pointed elytral apices, and the pubescent, more coarsely punctured, and 
very differently coloured under surface. 
19. Strongylium variicorne. (Tab. XV. fig. 9, 2.) 
Moderately elongate, slightly convex, bright greenish-sneous, the head and thorax and the base of the elytra 
slightly tinted with cupreous. Head very coarsely and rugosely punctured, very shallowly longitudinally 
impressed between the eyes, the latter small, feebly convex, and rather widely separated ; antennee very 
slender, widening outwardly, comparatively rather short (Q), joints 3 and 4 long, subequal, 5-7 subtri- 
angular, 8-10 subparalle!, about equal in length and width, longer than broad, 11 oblong ovate, 1 sneous, 
2-4, the basal half of 5, the apical half of 10, and 11 testaceous, the rest cyaneous; prothorax transverse, 
convex, the sides immarginate, a little rounded, slightly narrowing in front, and armed with a very short 
indistinct tooth in the middle, the base slightly sinuate, the apex straight, both somewhat strongly 
margined, the anterior angles obtuse, the hind angles rectangular, the basal foves very deep, the disc 
shallowly canaliculate and with a very irregular shallow excavation on each side about the middle, the 
surface very uneven and very coarsely and irregularly punctured, the punctures here and there confluent ; 
scutellum triangular, nearly smooth, cupreous in tint ; elytra moderately elongate, somewhat depressed on 
the disc, subparallel in their basal half, the surface from the base to the apex with irregular and much 
interrupted rows of very coarse and deep excavations, the excavations scarcely finer at the apex and 
at the base with punctiform impressions within, the interstices (the third especially) more or less strongly 
raised and very irregularly costate at the base, and obliquely or transversely confluent on the disc, 
smooth ; beneath glabrous, very shining, bright metallic purplish-cyaneous, the sides greenish-eneous 
with golden tints, very minutely and very sparingly punctured, the flanks of the prothorax and the sides 
of the metasternum very coarsely so; legs slender, moderately long, the femora coarsely but sparingly, 
the tibiz roughly and closely, punctured, greenish-wneous or golden-green, the femora at or towards 
the base, and the basal half of the tibie red, the tarsi and the extreme apex of the tibie cyaneous, the 
first joint of the posterior tarsi very much shorter than the apical joint. 
Length 94-104 millim.; breadth 27-33 millim. ( 9.) 
Hab. Panama, Volcan de Chiriqui 3000 feet (Champion). 
Two examples, apparently both females. Of the species here enumerated, S. varii- 
corne most nearly resembles S. costaricense ; it differs in the head being much more 
rugosely punctured, the eyes smaller and more widely separated, the antenne more
