56 HETEROMERA. 
tudinal impressions towards the suture and fine transverse wrinkles towards the margins, the entire 
surface sometimes with a few scattered indistinct punctures, the suture 1s depressed and flattened through- 
out its entire length; outer apical angle of the anterior tibie with a short blunt tooth. Beneath shining, 
with fine widely scattered punctures, the punctures a little coarser and closer along the sides and on the 
last ventral segments. 
Length 13-15 millim. (¢ 9.) 
Hab. Mexico (coll. F. Bates, Sallé), Oaxaca, Almolonga (Hége). 
Nine examples. 
12. Asida longipennis. (Tab. III. fig. 5, ¢ -) 
Elongate, rather convex, black, sparsely clothed with brown scales, Head impressed in front, and with an 
indistinct impression between the eyes; prothorax scarcely broader than long, closely and coarsely punc- 
tured, rugulose, rounded at the sides, the lateral margins slightly reflexed, slightly narrowed and sinuate 
behind before the rectangular hind angles, narrowed in front, the anterior angles prominent and slightly 
pointed, with a smooth central line, the disc with two rounded impressions on each side—one near the 
middle and another a little behind and nearer the lateral margin, base feebly bisinuate almost truncate ; 
elytra long, somewhat parallel, a little widened from the base to beyond the middle, narrowed rather 
suddenly behind with the apex a little produced, a little wider at the base than the thorax, with three 
well-defined smooth dorsal ridges (the outer short, not reaching the base) confluent behind the middle, a 
marginal ridge nearly reaching the apex and connected behind by a spur from the first dorsal ridge, the 
suture raised for its entire length, the interstices with scattered punctures ; antenne thin, intermediate 
joints long and obovate; outer apical angle of the anterior tibia with a long sharp spine, femora and 
tibie coarsely punctured. Beneath densely but not coarsely punctured. 
Length 13-15 millim. (¢ @.) 
Hab. Mexico, San Antonio de Arriba, San Andres (Salé). 
Two examples. Labelled Pelecyphorus longipennis, Chev., in the Sallé collection. 
13. Asida induta. (Tab. III. fig. 6.) 
Oblong oval, dull black, clothed with ferruginous scale-like hairs. Head with a rounded impression between 
the eyes, transversely impressed in front, finely and somewhat closely punctured ; prothorax transverse, 
rounded at the sides, closely and rather finely punctured, margins a little raised and expanded, narrowed 
and sinuate behind, the hind angles almost rectangular and not produced, narrowed and feebly sinuate in 
front, the anterior angles produced and pointed, the base almost truncate; elytra rounded at the sides, 
the humeral angles rounded, a little broader at the base than the thorax, widest about the middle, with 
three not very prominent dorsal ridges—the first distinct only at the base, obsolete behind, the second 
confluent before the apex with a marginal ridge and enclosing the shorter third dorsal ridge, interstices 
with a few scattered shallow punctures, the entire surface densely clothed with scales; outer apical angle 
of anterior tibia with a sharp tooth; femora and tibis coarsely punctured. Beneath coarsely and densely 
punctured. 
Length 12 millim. 
Hab. Mexico (coll. F. Bates). 
One example. I know of no near ally to this species. 
14. Asida guanajuatensis. 
Oblong oval, rather convex, somewhat densely clothed with light brown or ferruginous scale-like hairs. Pro- 
thorax a little broader than long, closely and coarsely punctured, rugulose, the disc with two rounded
