MORDELLISTENA, d41 
56. Mordellistena basimacula. (Tab. XV. fig. 13.) 
Elongate, subparallel, above and beneath, the oral organs, antenne, and legs flavo-testaceous, the scutellum 
and elytra black, the latter with a broad longitudinal flavo-testaceous stripe extending from the shoulders 
to nearly one third from the base, the pubescence partaking of the ground-colour. Head broad, the 
eyes moderately large ; last joint of the maxillary palpi rather stout, elongate, subsecuriform ; antenn 
filiform, slender, comparatively short, joints 3 and 4 short, subequal, together. as long as 5, 5-11 about 
twice as long as broad, subequal ; prothorax as long as broad; elytra elongate, subparallel in their basal 
half ; (pygidium broken off); the hind tibiee with three oblique ridges—the first extending across the outer 
face of the tibia to near the base, the others short; the first joint of the hind tarsi with three, the second 
joint with two, oblique ridges. 
‘Length to end of the elytra 4, breadth 1}, millim. 
Hab. GuatTEMa.a, Sinanja in Vera Paz (Champion). 
One example, probably a female. Broader than MV. Juteola; the eyes much smaller ; 
the elytra black, with a large, broad, flavo-testaceous humeral stripe. 
_ 57. Mordellistena occidentalis. 
Moderately elongate, narrow, subparallel, black, the head (the eyes excepted) and prothorax flavo- or reddish- 
testaceous, the base of the pygidium sometimes reddish; the pubescence on the elytra brownish or 
brownish-cinereous, for the rest partaking of the ground-colour. Head moderately large; maxillary palpi 
testaceous, darker at the tip, the last joint elongate-triangular and with its outer side slightly concave ; 
antenne very slender, filiform, moderately long in the male, shorter in the female, black or pitchy-brown, 
the basal four joints more or less testaceous, joints 3 and 4 short in both sexes, equal, 5 twice as long as 
4, 5-10 elongate, subequal, about twice as long as broad in the male, shorter in the female; prothorax 
not much broader than long; elytra moderately long, subparallel in their basal half; beneath, the head 
and prothorax excepted, varying in colour from black to reddish-testaceous; pygidium very elongate in 
the male, shorter in the female; the anterior and middle legs testaceous, the hind pair varying in colour 
from obscure reddish-testaceous to piceous; the hind tibiw with three ridges—the first extending obliquely 
across the outer face of the tibia to near the base, the second short, the third (subapical) very short; the 
first joint of the hind tarsi with three, the second joint with two, short, oblique ridges. 
Length to end of the elytra 23-33, to tip of the pygidium 3-33, millim. (¢ 9.) 
Hab. Muxtco, Chilpancingo in Guerrero 4600 feet (1. H. Smith). 
Numerous examples. Easily separable from all the allied forms, the following three 
species excepted, by the position of the carine on the hind tibie: of these the first 
extends completely across the outer face of the tibia. In the form of the antenne and 
the colour of the pubescence J. occidentalis is very similar to MM. azteca. 
58. Mordellistena oculata. 
Elongate, narrow, subparallel, pitchy-black, the head (the eyes excepted) reddish-testaceous ; the pubescence 
coarse, brownish. Head moderately convex, the eyes very large ; palpi testaceous, the last joint of the 
maxillary pair elongate-triangular; antenne testaceous with the apices of the outer joints infuscate, 
long and slender, filiform, joints 3 and 4 very short, equal, 5 more than twice as long as 4, 5-10 equal in 
length, 11 a little longer than 10; prothorax not much broader than long; elytra elongate, subparallel in 
their basal half; beneath piceous, the apex of each ventral segment testaceous ; pys gidium very elongate, 
two and a half times the length of the hypopygium ; legs piceous, the anterior pair almost entirely, the 
middle femora, and the hind tibial spurs testaceous; the hind tibiee with three well-defined ridges—the
