HETEROMERA. 
the base and obsolete before the apex, and a sharply defined marginal ridge, midway between the marginal 
and dorsal ridges there is [in some specimens] another ridge not reaching the base, the suture is indistinctly 
raised and slightly punctured, the ridges are connected by raised, prominent, transverse, sinuous wrinkles, 
the wrinkles finer and more numerous along the margin; outer apical angle of anterior tibiz with a sharp 
tooth. Beneath with scattered, coarse punctures and short longitudinal wrinkles; epipleurse with coarse, 
scattered punctures, vertical. 
Length 15-19 millim. 
Hab. Mexico (coll. F. Bates), Puebla (Sadié). 
Six examples. 
5. Asida clathrata. (Tab. III. fig. 2.) 
Pelecyphorus clathratus, Sallé in litt. 
Oblong oval, convex, depressed above, black with an wneous tinge, rather shining. Head transversely impressed 
in front; prothorax coarsely rugulose, the disc with a more or less smooth sinuous ridge on each side, and 
two rounded impressions near the centre, the ridges defined externally by an impression not reaching the 
base, rounded at the sides, a little broader than long, narrowed and sinuate behind, hind angles produced 
and prominent, though not acute, and overlapping the base of the elytra, narrowed in front with the angles 
produced and prominent, base bisinuate; elytra flattened, dilated, widened from the base to beyond the 
middle, with two flattened interrupted dorsal ridges, obsolete before the apex, and the outer of which 
often indistinct and not reaching the base, a marginal ridge sharply defined and slightly reflexed, the suture 
a little raised, flattened, and finely transversely strigose, the marginal and dorsal ridges and the suture 
are connected by transverse wrinkles, leaving each interstice with a series of oblong impressions, the 
whole surface with fine scattered punctures, humeral angles rounded; epipleure vertical, with scattered 
punctures ; a sharp spine at outer apical angle of the anterior tibia. Beneath with widely scattered fine 
punctures. 
Length 14-17 millim. (2 9.) 
Hab. Mexico (coll. F. Bates), Oaxaca (Hoge), Tehuacan, Cuernavaca (Sallé). 
This fine species is not. very closely allied to any other known to me. 
6. Asida morbillosa.

7. Asida asidoides. 
Pelecyphorus asidoides, Sol. Ann. Ent. Soc. Fr. 1836, p. 471, t. 11. f. 177. 
Asida asidoides, Lac. Gen. Col. v. p. 161, nota. 
Hab. Mexico (ex coll. Sturm).—? Cutt 1. 
Three examples. This species is labelled Asida asidoides in the Sallé collection, and 
agrees fairly well with Solier’s description. The locality given, Chili, is probably a 
mistake.
