STRONG YLIUM.—OTOCERUS. 377 
Elytra shorter than in §. apicicorne, similarly sculptured ; eyes moderate ; prothorax 
coarsely rugose ; legs and antenne shorter ; upper surface obscure greenish-bronze ; 
size small. 
67. Strongylium fragile. (Tab. XVI. fig. 17, 3.) 
Elongate, moderately convex, brownish-bronze, with an neous or greenish-eneous tint, rather dull. Head 
very coarsely and rugosely punctured, scarcely impressed between the eyes, the latter rather large and 
somewhat narrowly separated ; antenne rather stout, widening outwardly, joints 3 and 4 about equal in 
length, 4 widening at the apex and wider than 3, the penultimate joints slightly longer than broad, the 
apical joint ovate in the female, oblong-ovate in the male, piceous, tinged with eneous towards the base, 
the apical two joints usually testaceous or ferruginous ; prothorax transverse, convex, the sides immar- 
ginate, rounded, narrowing very little more in front than behind, and armed with a very short indistinct 
blunt tooth in the middle, the base a little sinuous, the apex straight, both strongly margined, the anterior 
angles obtuse, the hind angles subrectangular, the dise shallowly longitudinally impressed in the middle, 
the basal fovere deep, the surface uneven and exceedingly coarsely and rugosely punctured, the interspaces 
here and there forming very irregular smooth raised prominences ; scutellum subtriangular, finely punc- 
tured; elytra moderately long and convex, subparallel to beyond the middle, from the base to the apex 
with closely packed rows of deep coarse transverse or oblong excavations, the excavations frequently 
longitudinally confluent and at the extreme base punctiform, the interstices smooth, much raised, and 
more or less transversely confluent ; beneath reddish-brown, suffused with greenish-zneous, moderately 
shining, almost glabrous, closely and comparatively coarsely punctured; legs moderately long, sparingly 
but rather coarsely punctured, reddish-brown, suffused with greenish-sneous, the tarsi piceous, the first 
joint of the posterior tarsi shorter than the apical joint ; the fifth ventral segment with a shallow rounded 
impression in the middle behind in the male. 
Length 6-8 millim.; breadth 2-23 millim. (¢ 2 ) 
Hab. Panama, Bugaba, Volcan de Chiriqui (Champion). 
Numerous examples. In the elytral sculpture this species resembles S. apicicorne ; 
it differs, however, from that species in its less elongate shape, much smaller size, 
shorter and stouter legs and antenne, smoother legs, exceedingly rugose thorax, &c. 
The somewhat regularly reticulate interstices and the closely-packed rows of excavations 
on the elytra separate it at once from S. varticorne, &c.

ee species of this genus have been described, all from Tropical America, and 
numerous others exist in collections; the Brazilian O. longipes (Lucas) is here referred 
to Pseudotocerus. None have hitherto been recorded from our region, whence we 
have now to notice seven species. Otocerus is chiefly separated from Strongyliwm by 
the comparatively very short third joint of the antenne; in the more typical species,
