278 HETEROMERA. 
large humeral patch, a broad median fascia (divided at the suture by a very narrow line of cinereous 
pubescence), and the apex, rather broadly, black, for the rest densely cinereo-pubescent ; the pygidium 
cinereo-pubescent at the base, for the rest black. Last joint of the maxillary palpi moderately stout, 
triangular, its inner side shorter than the outer or apical sides; antenne black with the four basal joints 
testaceous, joints 3 and 4 slender, 5-11 moderately dilated and serrate, 5 triangular, twice as broad as 4, 
9 and 10 transverse ; elytra moderately long ; beneath cinereo-pubescent, the ventral segments marked 
with black at the sides, the last three with the apices also black; pygidium moderately long, rather 
stout, truncate at the tip, about twice as long as the hypopygium ; legs, including the tibial spurs, black. 
Length to end of the elytra 44, to tip of the pygidium 53, millim.; breadth 1? millim. 
Hab. Mexico, Tehuantepec (Salié). 
One example. In the markings of the upper surface this insect differs considerably 
from all the other Mordellw here described. It is, however, closely allied to several 
of the following species. The light pubescence is of an ashy-white colour. 
14. Mordella albopicta. 
Elongate, narrow, black; the head cinereo-pubescent; the prothorax (apparently) with a broad median black 
vitta (not reaching the base or apex and widened behind) and a large black spot on either side of it at 
the middle, for the rest cinereo-pubescent ; the scutellum cinereo-pubescent; the elytra with the suture 
at the base, a short curved stripe on the disc in front (widened behind so as to partly enclose a black spot 
and in one specimen extending narrowly along the base to the suture), a short oblique stripe or two spots 
below this externally, an oblong spot close to the suture before the middie (connected in one specimen 
with the sutural mark at the base), and a rather narrow fascia at one-third from the apex (not reaching 
the suture or lateral margin and deeply excised on its anterior edge) cinereo-pubescent, the rest of the 
pubescence black ; the pygidium cinereo-pubescent at the base, black beyond. Last joint of the maxillary 
palpi as in M, sellata; antenne piceous with the basal four joints fusco-testaceous, short, joints 3 and 4 
slender, 5-11 moderately dilated, subserrate, 5 triangular, twice as broad as 4, 6-8 about as broad as 
long, 9 and 10 transverse; elytra moderately long; beneath cinereo-pubescent, the sides in part black; 
pygidium rather short, moderately stout, blunt at the tip, about twice as long as the hypopygium ; legs, 
including the tibial spurs, black, the anterior and intermediate femora and tibiee fusco-testaceous in one 
specimen (<¢ ). 
Length to end of the elytra 4, to tip of the pygidium 43, millim.; breadth 13 millim. (¢.) 
Hab. Mexico, Cordova (Sallé). 
Two worn specimens only, one of which is a male. Allied to Jf. sellata, but with 
very different cinereo-pubescent markings. The light pubescence is almost white in 
one example. Labelled MU. albopicta, Chevr., in the Sallé collection. 
15. Mordella tetraspilota. (Tab. XII. fig. 4.) 
Elongate, rather narrow, the female broader, black; the head cinereous- or brownish-pubescent ; the pro- 
thorax with three broad black or blackish-brown vittee (the median one widened behind, the lateral ones 
oblique, the median sometimes divided before the middle by a fine transverse line of cinereous 
pubescence), the rest of the pubescence cinereous; the scutellum cinereo-pubescent ; the elytra each 
with an elongate oblique spot on the middle of the disc a little below the base, and a subquadrate 
transverse spot (not reaching the suture or lateral margin, and sometimes excised on its anterior or 
posterior edge) on the disc beyond the middle whitish- or cinereo-pubescent, the rest of the pubescence 
blackish-brown ; the pygidium cinereo-pubescent at the base laterally, for the rest black. Last joint of 
the maxillary palpi moderately stout, triangular, the inner side much shorter than either the outer or 
apical sides; antenne black, the basal three or four joints testaceous, joints 3 and 4 slender, 5-11
