MORDELLA. 297 
Hab. Guatemata, Cahabon (Chanvpion). 
One example only of this peculiarly coloured species was obtained. 
46. Mordella teapensis. (Tab. XIII. fig. 7.) 
Moderately elongate; the head testaceous, with a large rounded piceous patch in the middle; the prothorax 
flavo-testaceous, with a rather broad median vitta and the sides anteriorly black ; the scutellum black ; 
the elytra black, each with a broad flavo-testaceous discoidal stripe extending from the base nearly to 
the apex and reaching the suture behind ; the pygidium flavo-testaceous; the pubescence partaking of 
the ground-colour. Head convex ; palpi testaceous, the last joint of the maxillary pair elongate-trian- 
gular, rather narrow, its apical side much shorter than the inner or outer sides ; antennee long and slender, 
pitchy-brown, the three basal joints testaceous, joint 3 short, 4-11 moderately widened, much longer than 
broad, 4 much longer and wider than 3 but narrower than 5, 7-10 slightly decreasing in width; elytra 
convex, a little more than three times as long as the prothorax; beneath with the metasternum (except 
in the middle) and the sides of the ventral segments 1-4 black, for the rest flavous ; pygidium very slender 
and compressed, moderately long ; legs entirely flavo-testaceous ; hind tibie with traces of a faint dorsal 
carina. 
Length to end of the elytra 3, to tip of the pygidium 33, millim.; breadth 1 millim. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith). 
One specimen. Near WW. erythrocephala, but differing by its less elongate shape, the 
much more slender antenne, and the longer and narrower apical joint of the maxillary 
palpi, as well as in colour. The discoidal vitta on each elytron is broader and placed 
nearer the suture than in UW. erythrocephala. ‘The posterior cox are entirely flavous, 
as well as the ventral segments in the middle and the centre of the metasternum. 
47. Mordella flavifrons. (Tab. XIII. fig. 8.) 
Short, broad, thickly and uniformly clothed with cinereous or yellowish-cinereous pubescence, the pubescence 
paler on the light-coloured parts and a little more obscure on the dark parts but not forming spots or 
markings ; the head reddish- or flavo-testaceous, with the vertex black, the black colour sometimes more 
extended and reaching to the occiput, the eyes also black ; the prothorax more or less reddish or reddish- 
testaceous on either side of the middle anteriorly, this colour sometimes more extended so as to leave 
only a broad median vitta and a large patch on either side of the base laterally black or piceous; the 
scutellum and elytra black, the apex of the latter narrowly testaceous or yellow; the pygidium reddish- 
testaceous, darker towards the tip. Palpi testaceous, the last joint of the maxillary pair very broad and 
securiform in both sexes; antenne testaceous, long and very slender in both sexes, joints 3 and 4 thin, 
subequal, 5-11 a little widened, 5-10 very much longer than broad, feebly subserrate, 8-10 subequal, 11 
a little longer than 10; elytra short, not two and a half times the length of the prothorax ; beneath, 
the prothorax excepted, black, the ventral segments at the apex or in great part reddish-testaceous, 
densely and finely punctured, each ventral segment with a row of coarse punctures on the hind margin 
extending completely across, each of these punctures bearing a long coarse golden hair, the rest of the 
under surface cinereo-pubescent ; pygidium moderately long, rather slender, very little shorter in the 
female, more than twice the length of the hypopygium ; legs comparatively slender, the two anterior pairs 
(the apical half of the middle tibiee excepted) testaceous, the hind pair (the base of the tibie and the tips 
of the tarsal joints excepted) piceous, the tibial spurs testaceous; penultimate joint of the anterior and 
middle tarsi produced into a Jong broad lobe beneath the apical joint and extending to two-thirds of its 
length, the lobe excavate above for the reception of the last joint. 
Length to end of the elytra 3-37, to tip of the pygidium 34-4, millim. ; breadth 14-1} millim. (¢ 2.)
