288 HETEROMERA. 
(the former not nearly, the latter almost or quite, reaching the suture, the posterior one usually widening 
inwardly and with its upper and lower edges concave, the anterior one sometimes extending upwards to the 
shoulder), these markings golden-pubescent, the rest of the surface with dense brownish- or purplish-black 
pubescence. Palpi pitchy-brown, the last joint of the maxillary pair subtriangular, moderately broad ; 
antenne slender, testaceous, the outer joints sometimes darker, joints 3 and 4 short, not much longer than 
broad, 4 subtriangular, slightly wider than 3, 5-11 broader than 4, longer than wide, 5-10 scarcely serrate, 
subequal, 11 a little longer but not wider than 10; elytra scarcely narrower at the base than the pro- 
thorax, moderately long; beneath black, the ventral segments cinereo-pubescent at the base, for the rest 
clothed with dark brownish pubescence ; pygidium long and slender, considerably more than twice the 
length of the hypopygium in both sexes; legs piceous, the anterior and middle knees, tibie, and tarsi 
(except the tips), the hind tarsi in great part, and the base of the hind tibie and their spurs testaceous, 
the anterior and intermediate tibie slightly sinuous within in the male. 
Length to end of the elytra 3-32, to tip of the pygidium 4-43, millim.; breadth 13-13 millim. (¢ 92.) 
Hab. Mexico, Cordova (Sallé), Teapa in Tabasco (H. H. Smith); Guarema.a, San 
Gerdnimo, Capetillo (Champion). 
Seven specimens. ‘This species has, unlike most of the members of the genus, the 
pubescent markings of the elytra accompanied by a corresponding difference in the 
ground-colour, the pubescence in fact partaking of the colour of the surface from 
which it arises. The prothorax at the base is scarcely broader than the base of the 
elytra. The antenne have their joints 5—11 so feebly subserrate as to be almost filiform. 
M. flavofasciata cannot be confounded with any of the other species of Mordella here 
described, but it seems to come near the Brazilian MZ. fulvonotata, I. quadripustulata, 
and WM. decorata, Mak). 
32. Mordella flavonotata. (Tab. XII. fig. 19.) 
Moderately elongate, rather shining ; the head testaceous, with a piceous patch in the middle (this patch in 
one specimen much extended, so that only the sides and front of the head remain testaceous), the eyes 
black ; the prothorax flavo-testaceous, with a black median vitta extending from the base to the apex; 
the scutellum black ; the elytra black, with two flavo-testaceous transverse fasciw—one before and the 
other beyond the middle, the anterior one interrupted at the suture; the pygidium flavo-testaceous; the 
pubescence sparse and partaking of the ground-colour. Head regularly convex ; palpi testaceous, the last 
joint of the maxillary pair rather narrow, its apical side very much shorter than the inner or outer sides ; 
antenne testaceous, slender, moderately long, joints 3 and 4 short, small, subequal, 5-11 a little widened, 
longer than broad, 5 and 7 the widest; elytra convex, rather short; beneath with the metasternum 
(except in the middle), the sides of the posterior coxw in front, and the sides of the first three ventral 
segments black, for the rest flavo-testaceous ; pygidium exceedingly long (more than half the length of 
the elytra), slender, and acuminate, more than twice the length of the hypopygium; legs flavo-testaceous, 
the extreme apex of the hind tibie and of each hind tarsal joint piceous, the hind tibial spurs very 
elongate. 
Length to end of the elytra 23, to tip of the pygidium 34, millim.; breadth 1 millim. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith). 
Two examples. Resembling I. flavofasciata in the elytral markings ; but differing 
from it by the much longer pygidium, and by the head, thorax, and under surface 
being partly yellow. The upper surface is sparsely pubescent and rather shining. 
Evidently a close ally of the Brazilian MU. amena, Makl., but not altogether agreeing 
with the description of that insect, MM. flaviventris, Smith, from Texas and Florida,
