ASIDA. 53 
1. Asida mexicana. 
Pelecyphorus mexicanus, Sol. Ann. Soc. Ent. Fr. 1836, p. 469, t. 11. f. 11-16"; Dupont, Dej. Cat. 
ord ed. p. 207. 
Pelecyphorus pistrinarius, Chev. Dej. Cat. 3rd ed. p. 207. 
Hab. Mexico! (coll. F. Bates), Tehuacan (Sailé, Hoge). 
Apparently a common species, and sent by Hoge in large numbers. 
2. Asida rugosissima. (Tab. III. fig. 1.) 
Broad, convex, black, the depressions of the surface usually filled with earthy matter. Head dull, finely but 
not very closely punctured; prothorax very coarsely and closely punctured, rugulose, strongly transverse, 
rounded at the sides, a little broader behind than in front, base bisinuate, hind angles broad and promi- 
nent and a little produced behind; elytra short, dilated, strongly rounded at the sides, widest about the 
middle, narrowed suddenly and emarginate at the shoulders just before the base, the sharply toothed 
humeral angles hidden beneath the thorax, with two very prominent transversely wrinkled dorsal ridges 
confluent behind before the apex, a sharp marginal ridge and a row of flattened transverse elevations 
along the suture, the intervals very coarsely and transversely wrinkled; antenne with intermediate joints 
scarcely longer than broad; the outer apical angle of the anterior tibiz with a short, blunt tooth. 
Beneath dull, closely and finely punctured. 
Length 15-20 millim. 
Hab. Mexico, Hacienda de San Miguelito, Saltillo in Coahuila (Dr. Palmer). 
Four examples. Allied to Asida sordida, Lec., from New Mexico, but broader and 
shorter, the elytra more coarsely wrinkled, &c. 
3. Asida interrupta. 
Broad, convex, a little flattened above, black, the depressions usually filled with earthy matter. Prothorax 
rugulose, transverse, sides rounded, a little wider at the base than at the apex, hind angles acute and pro- 
duced behind, base bisinuate ; elytra short, rounded at the sides, widening a little from the base to about the 
middle, emarginate at the shoulders, humeral angles acutely toothed and hidden beneath the base of the 
thorax, with two transversely wrinkled dorsal ridges confluent before the apex, a sharp marginal ridge, 
and the suture a little raised and wrinkled, the intervals strongly wrinkled transversely; anterior tibiz 
with the outer apical angle produced into a blunt tooth. Beneath finely but not very closely punctured. 
Length 17 millim. 
Hab. Mexico, Ciudad in Durango 8100 feet (Forrer). 
One example. Allied to A. rugosissima, but smoother and flatter, the elytra less 
narrowed towards the base, the hind angles of the thorax produced and more acute, 
&c.: shorter and flatter than A. sordida and its varieties.

4, Asida funesta. 
Oblong oval, convex, a little depressed above, black, slightly shining. Head transversely impressed in front; 
prothorax coarsely and closely punctured, rugulose, transversely rugulose along the lateral margins, 
rounded at the sides, narrowed in front, the anterior angles produced, narrowed and sinuate behind, the 
hind angles produced and prominent, though not acute, and slightly overlapping the elytra, base bisinuate ; 
elytra somewhat dilated, widened from the base to beyond the middle, rather suddenly narrowed behind, 
and the apex a little produced, humeral angles rounded, with a very prominent dorsal ridge starting from
