p. 1 (1899) °. 
Moderately elongate, rather slender, smooth, shining; head and pronotum sordid white, the latter sometimes 
black with the anterior portion whitish and the cariniform elevations rufescent; the scutellum black or 
fuscous, with the apex more or less pale; the elytra varying in tint according to the predominance 
of the black or testaceous colour beneath, sometimes with several red spots at the humeral angles, 
appearing entirely whitish in pale specimens ; the under surface more or less testaceous, the venter black, 
with the median carina, the terminal segment, and some spots on the connexivum flavescent; antennze 
and legs testaceous, the four anterior tibie externally, and the posterior tibiee beneath, each with a more 
or less distinct darker streak down the middle, the hind tibie and tarsi with blackish hairs. Head (with 
the eyes) nearly as wide as the pronotum in the male, a little narrower in the female; interocular space 
narrow, becoming very narrow behind and here sometimes obsoletely carinate in the male, shallowly 
sulcate on the vertex. Pronotum short, about as long as the scutellum in the male, shorter in the 
female; the disc in the male with two deep elongate depressions towards the middle and a very large, 
deep, subtriangular depression on each side, these Jattcr almost enclosing an oblique oval elevation behind, 
the spaces between the depressions appearing raised and forming three longitudinal ridges. Legs rather 
slender; the anterior tibia in the male angularly dilated on the lower edge at the base, and also 
considerably widened. 
Length 44-6, breadth 13-2 millim. (¢ @.)

This is the commonest Anisops within our limits, and it has been found in plenty 
in the Pearl Islands by myself and by Mr. Gaumer in Yucatan. The specimens from 
Bugaba vary a good deal in size, and they are also blacker than the others; some of 
the females, too, from David (found with the ordinary males) have the pronotum very 
short, but all seem to belong to one variable species. The red spots at the humeral 
angles of the elytra, and those on the disc of the pronotum of the male, are evanescent. 
The pronotal structure separates it from all the other Central-American species, except 
A. carinatus, which is a larger and much more robust insect, and has the eyes less 
approximate. The male has larger eyes and deeper lateral depressions on the pronotum 
than the same sex of A. aldidus. One of the types, a male, of A. platycnemis, Fieb., 
belonging to the Berlin Museum, has been examined, and there seems to be no reason 
for treating this as distinct from the Antillean A. pallipes (Fabr.). A. elegans, Fieb., 
from “ America,” to judge from a drawing of the type, and its small size, probably 
belongs to the same species.

Elongate, narrow, rather slender, smooth, shining ; sordid white, the scutellum more or less rufo-testaceous, 
the legs, antennae, and under surface pale testaceous; the abdomen above testaceous, with transverse 
black bands, beneath black, with the median carina and some marks on the connexival segments pale 
testaceous. Head (with the eyes) narrower than the pronotum in both sexes; interocular space about
