NOSODERMA. 45 
elytra, hind angles almost rectangular, finely and equally granulated, with a distinct shallow central 
channel from base to apex; elytra subtruncate at base, humeral angles rounded and not prominent, sides 
almost straight to behind the middle, finely and equally granulated without any appearance of raised lines 
or tubercles, with four or five indistinct rows of shallow impressions towards the base, apices a little 
produced, equally rounded, and not separate at the suture. Legs black; antenne pitchy, submoniliform, 
the apical joint enclosed by the tenth, which is very large and truncate at apex; last joints of palpi red. 
Length 20 millim. 
Hab. Mexico, Parada (Saidé). 
One example. This species has quite a different facies from any of the Vosodermata 
known to me. 
2. Nosoderma asperatum. (Tab. II. fig. 9.) 
Elongate, rather convex, black, densely clothed with dull brown scales. Head almost impunctate; prothorax 
coarsely crenulate at the sides, longer than broad, base produced into a broad lohe, between which and 
the obtuse hind angles strongly emarginate, anterior angles rounded and prominent, the disc with a 
prominent sinuous ridge on each side, the ridges sharply defined outwardly by a deep excavation, with 
scattered, shining black granules; elytra with irregular rows of very prominent scattered elevations, 
which are conical in form towards the apex, and in the form of short ridges towards the base, the margins 
and spaces between the elevations with scattered rounded tubercles, the margins much interrupted and 
with the tubercles angular towards the apex, shoulders obliquely truncate, apices divergent, and each with 
a prominent tubercle. Beneath with scattered granules or elevations. Antenne with intermediate joints 
submoniliform. 
Length 12-14 millim. 
Hab. Muxico (Sallé, coll. F. Bates). 
Four examples. Allied to V. scabrosum, but shorter in form, a little more convex, 
the lateral margins of the thorax scarcely sinuous and very coarsely crenulate, the elytral 
tubercles more conical; the spaces between the larger elevations with scattered, small 
rounded tubercles.

Hab. Mexico}. 
I cannot satisfactorily identify this species amongst the very large number of Mexican 
Nosodermata contained in the Sallé and other collections; it is probable that one of the 
species here described will prove eventually to be identical with it. 
5. Nosoderma venustum. (Tab. II. fig. 7.) 
Elongate, dull black, the dense scaly clothing above dull brown with darker brown spots or markings. Head 
with the lateral margins swollen and raised ; prothorax much longer than broad, narrowed towards the
