MORDELLA. 293 
M. pustulosa, and in the elytral markings M. septemnotata ; the cinereous pubescence 
on the thorax and elytra, however, occupies a much larger portion of the surface than 
it does in M. septemnotata. The black apical fascia is partly interrupted in front, 
owing to the cinereous pubescence being extended a short distance downwards along 
the suture. The antenne are longer and more slender than in I. septemnotata, and 
have the basal joints testaceous. 
40. Mordella cata. 
Moderately elongate, black; the head, prothorax, and scutellum yellowish-cinereous-pubescent, the prothorax 
with an ill-defined black median vitta (not reaching the base or apex) and a large oblong black patch on 
either side of it; the elytra obscure castaneous at the shoulders, with an oblique stripe extending from 
the humeri towards the suture, a small spot below it on the lateral margin, an oblique spot extending 
outwards from the suture a little below the middle, the suture very narrowly from this spot to the base, 
and the base itself, narrowly, yellowish-cinereous-pubescent, for the rest clothed with black pubescence ; 
the pygidium blackish-pubescent. Palpi testaceous, the last joint of the maxillary pair a little darker at 
the tip, very broadly triangular, its apical and outer sides about equal in length, each a little longer than 
the inner side; antenne testaceous with the apical four joints pitchy-brown, long and rather slender, joint 
3 short, as long as but more slender than 2, 4~11 moderately widened, much longer than broad, 4 nearly 
twice as long as and very much broader than 3, 5-7 the widest, 11 oblong-ovate, the width and length 
of 10; elytra moderately long, rather convex ; beneath cinereo-pubescent, the ventral segments cinereo- 
pubescent at the base only, for the rest clothed with dark brownish pubescence ; pygidium long and 
rather slender, broad at the base, not quite twice the length of the hypopygium; the intermediate and 
posterior tibiee and tarsi in great part and the anterior legs entirely testaceous, the four hinder femora 
piceous. 
Length to end of the elytra 44, to tip of the pygidium 53, millim.; breadth 13 millim. 
Hab. Mexico, Cordova (Sallé). 
One example, probably a male. Somewhat resembling J/. arcwata in the arrange- 
ment of the cinereous pubescence of the elytra (in M. arcuata, however, the suture is 
not cinereo-pubescent); but much smaller than that insect, the apical joint of the 
maxillary palpi broadly triangular, the antenne more filiform and with the fourth joint 
stouter, the pygidium more slender and almost pointed, and the post-median fascia of the 
elytra reduced to an oblique mark on either side of the suture. The yellowish-cinereous- 
pubescent markings on the basal portion of each elytron almost enclose a large blackish- 
pubescent spot. 
41. Mordella leucogramma. (Tab. XIII. fig. 1, 2.) 
Elongate, rather narrow, black ; the head cinereo-pubescent ; the prothorax with a black median vitta (slightly 
widened behind and not quite reaching the base or apex) and a very large black triangular patch on either 
side of it, the rest of the pubescence cinereous ; the scutellum cinereo-pubescent; the elytra each with an 
oblique curved stripe extending from the shoulders downwards towards the suture and widened behind 
into a rather large patch (so as to partly enclose a large black basal spot), a curved oblique stripe below this 
externally (more or less divided into two spots—one on the disc and one some distance below the shoulder), 
a rather broad fascia beyond the middle (excised on its lower edge, curving a little downwards towards 
the suture, and sometimes not reaching the suture or lateral margin), and the base behind the scutellum 
einereo- or whitish-pubescent, the rest of the pubescence black ; the pygidium cinereo-pubescent to about 
the middle, black beyond. Palpi testaceous, the last joint of the maxillary pair darker, the latter very 
large, stout, and subequilaterally triangular in the male, smaller and subcultriform in the female; antenne
