rows; a large irregularly subcordate black central spot (larger than that of 
the thorax) occupies the sutural part, placed under the seutellum ; its pos¬ 
terior point is elongated as far as beyond the middle of the elytra. 
Pygidium oblique, subtrigonal, convex, punctate-rugulose; black, with 
the basal third part covered with a light brown pile, and in the middle of the 
base an oblong-ovate spot, formed with very dense whitish hair of the finest 
texture: the two apical third parts have only a very short, thin and distant 
gray pile, which exposes the black ground; also a minute oblong-punctiform 
white spot is placed behind the basal one, and occupies exactly the centre 
of the pygidium. 
Body beneath:— Pectus densely punctulate, and between the punc¬ 
tures larger, deeper and remoter punctures are observable. Disc of 
the metasternum covered with a short thin ashy pile, external densely 
clothed with fine subochreous-yellow hair. Pectoral lamince densely and 
rather deeply punctulate, black, shining. Abdomen densely and finely 
punctulate, black, covered with a short, thin, ashy, subsericeous pile, con¬ 
densed into five marginal whitish spots, placed on each ring ; the first very 
large, subnebulous ; the others minute, punctiform, well circumscribed. 
Legs :—Anterior slender (first pair smaller than the second), pale fer¬ 
ruginous, shaded with a very thin whitish gray pile. Posterior long: thighs 
very strong and clavate, extending a third of their length beyond the apex 
of the elytra, almost reaching the tip of the pygidium; having beneath, 
near the apex, three or four very thin and short spines inside, and outside 
two others, one very long, the furthest from the tip, the other not far from 
it, but not so near as the last of the inner row. Tibiae curved, one-third 
shorter than the thighs, flat underneath, convex above, with an angular 
ridge near the inner side, which is also ridged and terminated with a long 
spine; the apex truncate, with two other very short and indistinct spines 
at the outer angle. Thighs and tibiae pitchy, scattered over with a very 
thin gray pile; external part of the former ferruginous, with two nebulous 
whitish fasciae. Tarsi sublinear,, nearly as long as the tibiae, dull ferrugi¬ 
nous; first joint nearly half the total length, slightly curved.
