92 HETEROMERA. 
emarginate in front (the ocular canthus extending more than halfway across), narrowly separated in the 
male, more distant in the female; antenne moderately long, joints 2 and 3 in the male very short, equal 
in length, and together not nearly so long as 4, joint 3 in the female half as long again as 2; prothorax 
transverse, narrowing from the base, the sides much rounded in front, the hind angles acutely rectangular, 
the basal fovese shallow, the disc sometimes obsoletely canaliculate, the base feebly bisinuate and almost 
straight, the surface coarsely, closely, and roughly punctured ; scutellum coarsely punctured ; elytra widest 
a little before the middle and narrowing thence to the apex, closely and moderately coarsely punctured ; 
beneath finely and sparsely punctured, the metasternum coarsely so at the sides and smooth in the 
middle; anterior and intermediate tarsi distinctly, the posterior tarsi very narrowly and indistinctly, 
lobed beneath. 
Length (with the head extended) 32-44 millim. (d 2.) 
Hab. Guatemata, San Gerénimo 3000 feet (Champion); Panama, Volcan de Chiriqui 
3000 feet (Champion). 
Seven examples from Guatemala and two from the State of Panama. Smaller and 
more narrowed behind than C. speciosa; the antenne shorter and more slender; the 
eyes more deeply emarginate; the thorax with shallow basal fovee and the base more 
truncate; and the penultimate joint of the hind tarsi indistinctly lobed. The last 
ventral segment in the male has very long, curved, and greatly-developed lateral lobes. 
8. Canifa circumdata. (Tab. IV. fig. 22, ¢.) 
Moderately elongate, pallid testaceous, the sides and apex of the elytra, and the sides of the prothorax less 
distinctly, piceous brown, sparsely pubescent, slightly shining. Head closely and coarsely punctured ; 
eyes (¢) black, very deeply emarginate, narrowly separated; antenne ( ¢') pallid testaceous, rather stout, 
joints 2 and 3 very short and equal, together about half the length of 4; prothorax strongly transverse, 
about twice as broad as long, convex, narrowing from the base, the sides much rounded, the hind angles 
rectangular, the basal fovee minute, transverse, and placed just within the margin, the disc shallowly 
impressed in the middle towards the base, the surface closely, moderately coarsely, and rather roughly 
punctured; scutellum similarly punctured; elytra widest about the middle, rather obtuse behind, more 
sparsely and much more coarsely punctured than the prothorax; beneath testaceous, the venter stained 
with piceous ; legs pallid testaceous; the penultimate joint of all the tarsi (that of the posterior pair less 
distinctly) lobed beneath. 
Length (with the head extended) 3 millim. (<¢.) 
Hab. Gvatemata, El Tumbador 2500 feet (Champion). 
One male example, captured on the Pacific slope of Guatemala. This small species 
may be readily identified by its system of coloration. The thorax is comparatively 
very short and has very minute basal fovee ; the elytra are comparatively more coarsely 
punctured than in the two preceding species, the punctuation being considerably 
coarser than that of the thorax. 
EVALCES. 
Last joint of the maxillary palpi elongate, subtriangular, its apical side much shorter than the outer side and 
somewhat rounded ; last joint of the labial palpi broad ovate, its apex truncate; mentum about as long as 
broad, sinuate at the sides, broadest behind; lobes of the maxille long, the inner one very narrow ; 
mandibles simply unidentate; head vertical, comparatively narrow, rather long, a little rounded behind, 
suddenly constricted into a neck as in Scraptia; eyes small, similar in both sexes, deeply emarginate in
