CANIFA. 91 
The species of this and of the following genus are found about the branches of 
felled or decaying trees. 
1. Canifa speciosa. (Tab. IV. figg. 21,3; 21a, labium; 210, maxilla and 
maxillary palpus; 21 ¢, mandible.) 
Elongate, subparallel, flavo-testaceous or testaceous, the elytra sometimes with a brownish or piceous ill- 
defined sublateral stripe, sparsely pubescent, moderately shining. Head very coarsely and closely punc- 
tured; eyes black—in the male very large and subapproximate, in the female smaller and much more 
distant; antenne testaceous—in the male very long, fully reaching to the middle of the elytra, with 
joints 2 and 3 very short and equal, 4 three or four times as long as 3, and 4-11 very elongate and sub- 
equal—in the female shorter and more slender, and with joint 3 considerably longer than 2 and about half 
the length of 4; prothorax transverse, the sides much rounded anteriorly and straight behind, gradually 
narrowing from the base in some examples, the hind angles rectangular or subrectangular, the basal 
foveee large and very deep, the disc usually more or less distinctly canaliculate, the base trisinuate, the 
surface coarsely, closely, and roughly punctured; scutellum coarsely punctured; elytra long and sub- 
parallel, closely and moderately coarsely punctured; beneath finely and rather sparsely, the sides of the 
pro-, meso-, and metasternum densely, punctured; legs hairy, testaceous; the penultimate joint of all the 
tarsi lobed beneath, that of the two front pairs broadly so; anterior tibie slightly, the intermediate tibie 
more or less distinctly, sinuate in the male, the anterior pair in some examples slightly dilated on the 
inner side near the base. 
Length (with the head extended) 5-83 millim. (¢ 2.) 
Hab. Mexico, Real del Monte in Hidalgo, Jalapa (Hédge); GuatemaLa, Coban 
(Conradt), San Joaquin, Cerro Zunil 4000 feet (Champion). 
Var. Prothorax not so coarsely or roughly punctured; the eyes less approximate and the anterior tibie 
triangularly dilated on the inner side before the middle in the male. 
Hab. Mexico, Omilteme 8000 feet, Xucumanatlan, Amula, and Chilpancingo in 
Guerrero (H. H. Smith). 
This species is not uncommon in Mexico and Guatemala, whence we have about 
forty specimens. C. speciosa varies greatly, not only in size but in sculpture and in the 
development of the male characters. In the examples from each of the localities 
slight differences are to be found, though not of sufficient importance to be regarded 
as specific. The antennee of the male are stouter than those of the female. In the 
single male of. the variety the anterior tibie are triangularly dilated within and the 
middle tibie are more sinuous; intermediate examples, however, occur. Some of 
our specimens are of a piceo-testaceous colour, but this is probably due to discoloration. 
The apical point of the labial palpi (as in Scraptia &c.) is transversely securiform and 
exceedingly broad, its apical side very much longer than the outer side. A male from 
Cerro Zunil (where examples of both sexes of the insect were captured in numbers) is 
shown on our Plate. 
2. Canifa oculata. 
Elongate, narrowing posteriorly, above and beneath (the eyes excepted), antennz, and legs flavo-testaceous, 
sparsely pubescent, slightly shining. Head very coarsely and closely punctured; eyes black, very deeply
