290: HETEROMERA. 
maxillary palpi is broadly securiform ; the antennz long and slender. M. lineatipyga 
is not at all closely allied to any other species here described. © 
85. Mordella univittata. (Tab. XII. fig. 22.) © 
Elongate, convex, black, very densely punctured ; the head, prothorax, and scutellum densely clothed with 
yellowish-cinereous or golden pubescence, the prothorax with a faint median blackish-brown-pubescent 
vitta and a large similarly coloured oblong spot on either side of it (the former much narrowed in front, 
extending to the apex and almost: to the base, the latter placed nearer to the base than to the apex); the 
elytra each with a broad oblique stripe on the disc extending from the shoulder to the apex and the suture 
narrowly from the base downwards yellowish-cinereous- or golden-pubescent, for the rest clothed with 
blackish-brown pubescence ; the pygidium yellowish-cinereous-pubescent to about the middle, darker 
beyond. Head very convex; palpi testaceous, the last joint of the maxillary pair stout, broadly trian- 
gular; antenne pitchy-brown with the two basal joints testaceous, long and slender, joints 3 and 4 thin, 
subequal, 5-11 moderately widened, much longer than broad, 5-10 subserrate, almost equal in length, 5-7 
rather wider than the following joints, 11 a little longer than 10 ; elytra moderately long; beneath densely 
and uniformly clothed with yellowish-cinereous pubescence, without darker markings; pygidium rather 
slender, elongate, pointed at the tip, more than twice the length of the hypopygium ; legs black, the anterior 
and intermediate coxe, femora, and tibie (the apical half of the latter excepted), and the hind tibial spurs, 
testaceous. 
Length to end of the elytra 33-4, to tip of the pygidium 43-53, millim.; breadth 13-13 millim. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith); Panama, Bugaba (Champion). 
Two examples, agreeing perfectly with each other; the one from Bugaba is a female, 
the other possibly a male. In this species the head is very convex, much as in Tomoazia 
interrupta and T. fulviceps. It may be recognized from the other Mordelle here 
described by the broad uninterrupted oblique stripe of yellowish-cinereous pubescence 
on each elytron, this stripe extending from the shoulder to the apex and there connected 
with the very narrow sutural one. ‘The antenne are long and comparatively slender, 
the last joint of the maxillary palpi is broadly triangular, and the pygidium is elongate 
and rather narrow. 
36. Mordella atricolor. 
Elongate, rather broad, entirely black, the pubescence above and beneath black, the elytra in one example 
with a few scattered intermixed single cinereous hairs. Labrum, mandibles, and palpi black, the last 
joint of the maxillary palpi stout, triangular; antenna biack, long, joints 4-11 moderately widened, 4 
much wider and longer than 3, 5 broader than 4, 6-10 obliquely subquadrate, about as broad as long, and 
decreasing slightly in width, 11 longer and rather narrower than 10; prothorax with the median basal 
lobe broadly rounded ; elytra comparatively long and convex; pygidium conical, moderately long, about 
twice the length of the hypopygium ; legs entirely black, comparatively stout. 
Length to end of the elytra 54, to tip of the pygidium 6%, millim.; breadth 23 millim. 
Hab. Mexico, Hacienda de la Imagen 4000 feet, Acaguizotla 3500 feet, both in 
Guerrero (H. H. Sinith). 
Two examples. Exceedingly like the European WM. aculeata, Linn., but differing 
from it by its larger size, stouter build, broader apical joint of the maxillary palpi, and 
black mouth-parts, and also by the form of the antenne—in WV. aéricolor joints 6-10
