CONOMORPHUS. 99 
footnote on p. 100); and Calophthalmus tenuicornis, Fairm., from Minas Geraes, 
doubtless belongs to the same genus. As in Stilpnonotus, a short space on either side 
of the suture of the elytra near the apex is usually darker in colour, and the suture at 
this part longitudinally impressed on each side. C. pilosus (from which the description 
of the mouth-parts is taken) may be considered as the type of the genus. ‘The sexes do 
not exhibit any external distinguishing characters. 
Our specimens of C. pilosus and C. hrevicornis were beaten from the withered branches 
of fallen trees. 
1. Conomorphus pilosus. (Tab. V. figg. 2; 2a, labium; 26, maxilla and 
maxillary palpus.) 
Subcylindrical, narrowing anteriorly, piceo-castaneous, sometimes with a slight seneous lustre, moderately shining, 
somewhat thickly clothed with rather long appressed hairs. Head very closely and rather coarsely punc- 
tured; eyes black, widely separated; antenne slender, extending to a little beyond the base of the 
prothorax, varying in colour from piceous to ferruginous, joints 4-10 subtriangular, decreasing in length 
and increasing in width, but all much longer than broad, 11 ovate, and much longer than 10; prothorax 
subquadrate, as long as broad, the sides immarginate, the disc a little depressed, more or less distinctly 
canaliculate (more deeply so behind), and sometimes with a shallow oblique impression on each side 
towards the base, the basal fovese deep, extending obliquely upwards for a short distance, and usually 
connected by a shallow groove, the surface densely, subrugulosely, and somewhat coarsely punctured ; 
scutellum flat, densely punctured; elytra gradually widening to about the middle and thence to the apex 
converging, slightly depressed on each side within the humeri, the disc shallowly transversely impressed 
some distance below the base, the suture for a short distance longitudinally impressed on each side near 
the apex, a narrow space external to this more or less piceous in colour, the surface rather more finely 
and much more sparsely punctured than the prothorax, more closely so towards the base, the posterior 
half often with traces of very shallow longitudinal grooves; beneath shining, the ventral surface and 
metasternum closely and finely punctured, the rest coarsely and densely so; legs more or less piceous, the 
base of the femora and the basal half and the apex of the tibize often reddish. 
Length 7-114 millim. 
Hab. GuateMata, Cerro Zunil 4000 feet (Champion). 
Six examples. This species is no doubt allied to Calophthalmus tenuicornis, Fairm. 
2. Conomorphus brevicornis. (Tab. V. fig. 3.) 
Subconical, fulvo-testaceous, the head and prothorax of a more ferruginous colour, the latter with the sides 
broadly, and the elytra with a sinuous sublateral stripe, extending from the shoulder to about the middle 
and there turning abruptly inwards and then again outwards, enclosing a triangular lateral patch (this 
being flavous in colour in one example), and sometimes a common sutural patch just before the apex, 
piceous or black, slightly shining, the surface clothed with short appressed pubescence. Head very closely 
and finely punctured ; eyes black, rather widely separated; antenne yellow, short, scarcely reaching the 
base of the prothorax, slender, widening outwardly, joints 4-10 gradually becoming more triangular in 
shape, 7-10 very distinctly so, 9 and 10 as broad as long, 11 much longer than 10 and ovate; prothorax 
cylindrical, subquadrate, as broad as long, the sides very feebly rounded or almost straight, and very 
obsoletely margined behind, the disc longitudinally impressed in the middle behind and a little flattened, 
the base with a well-defined groove connecting the short basal foves, the surface very densely and finely 
punctured and subopaque ; elytra gradually widening to the middle and thence to the apex converging, 
very closely and finely punctured throughout, the suture slightly depressed just before the apex; beneath 
very closely punctured ; legs flavous or ferruginous. 
Length 4-53 millim.
