3. Rather short and broad, comparatively robust, shining ; pale testaceous, the eyes black, the pronotum 
with 7—9 transverse black lines, which are narrower than the pale interspaces ; the elytra nigro-fuscous, 
the clavus, corium, and membrane closely marked with short, irregular, undulate, transverse, pale lines, 
these becoming wider and quite straight on the basal portion of the clavus, the marginal area testaceous, 
in some specimens black below the base, beyond the middle, and at the apex ; the meso- and metanotum, 
and the dorsal segments of the abdomen, sometimes partly black ; the legs entirely pale. Head with two 
rows of punctures on the vertex and some punctures near the eyes; the frontal depression very large, 
oval, deep. Pronotum obsoletely rastrate, not carinate. Elytra with the clavus very sparsely, obsoletely 
rastrate, the corium very minutely punctulate. Anterior femora stout, subangularly dilated on the lower 
side at about the middle; anterior tibiw broadly dilated, triangular, acutely produced at the outer apical 
angle; pale broad, strongly rounded on their outer edge, blunt at the tip, with numerous long hairs on 
the inner edge. Intermediate tibice about one-half longer than the tarsi, the tarsi a little shorter than the 
claws. Ventral segments asymmetric on the left side. Strigil absent. 
Q. Head without frontal depression ; anterior tibiw not dilated; pale much narrower. 
Length 63-63 millim.

Several specimens of both sexes. Recognizable by the acutely triangularly dilated 
anterior tibiz in the male, and the absence of a strigil in this sex. ‘The elytra are 
closely and irregularly vermiculate with pale lines, these, however, becoming straight 
towards the base of the clavus. C. cube, according to Guérin’s figure, has the anterior 
tibiz not so acutely produced at the apex, and the pale more curved, in the male. 
4, Corixa guatemalensis, n. sp. (Tab. XXII. figg. 19, 194, 4, 3.) 
do. Rather short, comparatively broad, shining; the head flavous, the eyes black; the pronotum with about 
seven black and seven obscure testaceous transverse lines, of almost equal width; the mesonotum black ; 
the elytra nigro-fuscous, the clavus and corium only with obscure paler transverse lines, the marginal 
area black, the membrane immaculate; the body beneath pale testaceous, the abdomen in great part 
black ; the legs flavo-testaceous, the long hairs on the hind tarsi black. Head with two interrupted 
rows of punctures on the vertex, and some other punctures near the eyes, and with a long, oval, 
moderately broad, frontal depression. Pronotum obsoletely rastrate, not carinate. Elytra with the 
clavus and the base of the corium finely rastrate. Anterior tibie broad, subtriangular ; pale moderately 
broad, subparallel at the base, rounded on their outer edge towards the apex, the latter somewhat pointed. 
Intermediate tibia much longer than the tarsi, the tarsi and claws subequal in length. Ventral segments 
very asymmetric on the right side. Strigil on the left side, broader than long, with five rows of teeth. 
9. Head without frontal depression ; anterior tibiz not dilated ; pale a little narrower. 
Length 53-53 millim. 
Hab. GuaTemata, near the city (Champion). 
Six specimens. A small obscurely-coloured species, chiefly distinguishable by the 
triangularly dilated anterior tibiz in the male, and the finely rastrate clavus. It is 
smaller than C. kollari, the clavus is more distinctly rastrate, and the indistinct elytral 
markings are much more regular.
