346 HETEROMERA. 
Elytra very coarsely foveolate-striate throughout. 
* Prothorax very coarsely rugosely punctured; eyes large and approximate in the 
male, smaller in the female; upper surface dull dark bronze, the elytra with 
a cupreous tint.

Serangodes excavatus, De}. Cat. 3rd edit. p. 229°. 
Strongylium cribrosum, Mannerh. in litt. 
Hab. Mexico 12, Oaxaca (coll. Mannerh.), Cordéva, Catemaco ( Sallé) ; GUATEMALA, 
Cubilguitz (Champion); Nicaragua, Chontales (Belt, Janson). 
** Prothorax coarsely and closely punctured ; eyes small ; upper surface 
more shining, greenish-bronze. 
10. Strongylium canaliculatum. (Tab. XV. fig. 3, 2.) 
Oblong ovate, rather convex, greenish-eneous, not very shining. Head very coarsely and rugosely punctured, 
very shallowly impressed between the eyes, the latter small, very feebly convex, and widely separated ; 
antenne (@) short, very distinctly widening outwardly, joints 3 and 4 long, subequal, 5-7 subtriangular, 
8 about as broad as long, 9 and 10 transverse, 11 longer than 10, short ovate, 1-6 testaceous, much suffused 
with greenish, the rest dull dark cyaneous ; prothorax rather convex, broader than long, the sides immargi- 
nate, rounded and narrowing in front, and almost straight or but little narrowed behind, the anterior angles 
rounded, the hind angles subrectangular, the dise very distinctly and somewhat deeply canaliculate, and 
with a deep impression on each side immediately above the deep basal fovez, the surface very coarsely and 
closely punctured ; scutellum subtriangular, sparingly punctured; elytra comparatively short, moderately 
convex, a little 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 punctiform 
at the base and there arranged in more regular rows, the interstices irregularly raised and obliquely or 
transversely confluent, smooth ; beneath more shining, greenish-zeneous, very slightly pubescent, sparingly 
but not very finely punctured, the fifth ventral segment and the other segments at the sides more coarsely 
and closely so, the metasternum at the sides and the flanks of the prothorax very coarsely punctured ; 
legs short, stout, very closely and coarsely punctured, seneous or greenish-sneous, the tarsi cyaneous, the 
first joint of the posterior tarsi much shorter than the apical joint, the anterior and intermediate tibic (in 
the female) short, curved, and somewhat dilated. 
Length 9-102 millim.; breadth 3-4 millim. ( 2.) 
Hab. Mexico (Sallé); Guaremata, Teleman (Champion). 
Three female examples. The stouter and shorter legs, the longer, more distinctly 
canaliculate, and much more finely punctured thorax, and the shorter and more parallel 
elytra separate this species from S. chiriqguense, which it otherwise closely resembles. 
From S. excavatum it is distinguished by its smaller size, the small and widely separated 
eyes, the punctures of the thorax separate one from another, the excavations of the 
elytra much more irregular and coarser, the elytra themselves shorter, the much shorter 
legs, &c. The single example from Mexico is larger, and has the elytral excavations 
still coarser and deeper and more irregular than in the two Guatemalan specimens ; 
one of the latter is figured.
