MORDELLA. 303 
5-11 equal in width), longer legs, longer pygidium, and different thoracic and elytral 
markings. The peculiarly shaped dark markings on the centre of the thorax are very 
sharply defined from the dense pale pubescence ; the elytra have, as in M. varicornis 
&c., numerous punctiform subserially arranged spots in addition to the larger markings, 
these latter being more extended on the basal portion than they are in MV. sticticoptera 
and WW. seriata. The legs are very elongate, especially the intermediate pair. 
56. Mordella tenuipes. (Tab. XIII. fig. 17.) 
Moderately elongate, rather broad, brownish-black; the head and prothorax clothed with yellowish-cinereous 
pubescence, the latter with a broad median brownish-black-pubescent vitta and an oblique similarly- 
coloured stripe on either side of it (the former narrowing anteriorly and interrupted in front by a trans- 
verse line of light pubescence, the two latter widening posteriorly, these markings not quite extending to 
the base or apex); the scutellum brownish-black-pubescent; the elytra with numerous small yellowish- 
cinereous-pubescent spots scattered all over the surface, these spots coalescing here and there and at one 
third from the apex forming a rather broad irregular fascia and at the base laterally a short stripe, the 
rest of the pubescence brownish-black; the pygidium yellowish-cinereous-pubescent at the base, brown 
towards the tip. Palpi testaceous, the last joint of the maxillary pair darker, the latter slender, oblong- 
ovate; antenne long and very slender, thickening a little outwardly, obscure testaceous, the apical four 
joints piceous, joints 3 and 4 very elongate and thin, subequal, 5 considerably longer than 4, widening 
outwardly, 6—10 slightly wider, about equal in width but gradually decreasing in length, all much longer 
than broad and scarcely subserrate, 1] stouter and one half longer than 10; elytra moderately long; 
beneath blackish-brown, the venter paler, yellowish-cinereous-pubescent ; pygidium short and stout, almost 
‘pointed at the tip, not twice the length of the hypopygium ; legs long and slender (the hind pair excepted), 
in great part obscure testaceous, the hind femora piceous, the anterior and intermediate tibiee and tarsi 
very long and thin, the intermediate tarsi distinctly longer than the tibiee of the same pair of legs, the 
penultimate joint of the four anterior tarsi filiform. 
Length to end of the elytra 3, to tip of the pygidium 4, millim.; breadth 14 millim.

One example only. MV. tenuipes is not at all closely allied to any of the other species 
here described, but (though much smaller) perhaps comes nearest to M/. pretiosa. The 
four anterior legs are exceedingly slender and elongate; the antenne are subfiliform, 
long, and very slender, but a little thickened outwardly; the apical joint of the maxil- 
lary palpi is quite slender, oblong ovate in shape; the pygidium is short and stout, 
but pointed at the tip. The antenne, legs, and palpi are still more slender than in 
M. pretiosa; the elytra (but not the head and thorax) are marked somewhat as in 
that species. — 
57. Mordella tantilla. 
Short, cuneiform, black, the mouth-parts (the tips of the mandibles excepted) testaceous, above and beneath 
uniformly clothed with brownish-cinereous pubescence. Last joint of the maxillary palpi piceous, stout, 
subtriangular, its apical and inner sides about equal in length, and both much shorter than the outer side ; 
antenne piceous with the basal four joints testaceous, very short, joints 3 and 4 narrow, equal in length, 5- 
11 alittle widened, 5-10 serrate, decreasing in length but increasing in width, 9 and 10 transverse, 11 a little 
longer than 10, blunt at the tip; elytra short, convex; pygidium very long and almost pointed, more than 
twice the length of the hypopygium ; legs (the hind pair excepted) long and slender, black, the anterior
