90 HETEROMERA. 
7. Symphora elongata. 
Elongate, convex, moderately narrowed posteriorly, brownish-black, the head (the eyes excepted) reddish- 
testaceous, sparsely pubescent, slightly shining. Head finely and very closely punctured, the eyes moderately 
large, the palpi fusco-testaceous; antenne long, the joints elongate, 1-6 testaceous, the rest piceous ; 
prothorax convex, strongly transverse, the sides slightly rounded and narrowing from a little before the 
base, the surface densely and rugulosely punctured and without impressions ; elytra narrowing from about 
the middle, very closely and rather coarsely punctured; beneath (the head excepted) brownish-black, 
closely and coarsely punctured, the ventral surface much more finely so; legs fusco-testaceous, the femora 
and coxe flavo-testaceous. 
Length 3 millim. (<¢.) 
Hab. Guatemata, Capetillo (Champion). 
One specimen. This species is closely allied to S. convexa, but differs from it in its 
less arcuate shape (viewed laterally and longitudinally), much longer antenne, more 
closely punctured head, and paler legs, and, more particularly, in the elytra being more 
parallel and less narrowed behind. 
Group SCRAPTIIDES. 
CANIFA. 
Canifa, Leconte, New species Col. p. 14-4 (1866) ; Leconte and Horn, Class. Col. N. Am. p. 399 
(1883). 
Leconte has separated the North-American Seraptie into three genera, Scraptia, 
Allopoda, and Canifa, basing these chiefly upon differences in the shape of the apical 
joint of the maxillary palpi and upon the lobing or not of the penultimate joint of the 
tarsi. ‘Three species from Central America agree very well with Canifa in having the 
apical joint of the maxillary palpi rather long and subcultritorm, the third joint of the 
antennee very short in the male, the penultimate joint of all the tarsi lobed beneath, 
and the first joint of the hind tarsi about twice as long as the following joints united ; 
they are accordingly referred to that genus. For the other allied forms from our 
region a new genus has been required. Four species of Canifa have been recorded, all 
from the United States. In those from Central America here described the sexes show 
a very marked disparity in the size of the eyes (at least in C. speciosa) and in the form 
of the antenne *, the latter, as in certain species of Cistela, having the second and third 
joints in the male very short and equal in length and together only about, or not much 
more than, half as long as the fourth joint. Cteniacantha marginata, Qued., from Puerto 
Rico, to judge from the description and figure (cf. Berl. ent. Zeitschr. 1886, pp. 119- 
121), is, no doubt, very closely allied to the species here referred to Canifa; but these 
latter have the mandibles strongly bifid (at least in C. speciosa), the apical joint of the 
maxillary palpi only moderately elongate, and the tibial spurs not or scarcely pectinate, 
characters not agreeing with Quedenfeldt’s description. 
* This is not mentioned by Leconte.
