ASIDA. 61 
impunctate, short, broad, a little narrowed at the base, rounded at the sides, widest a little behind the 
middle, humeral angles obtuse, with a crenulate marginal ridge starting from the shoulder and obsolete 
before the apex, base emarginate and raised on each side of the large triangular scutellum, concave in the 
middle; anterior tibie with a blunt tooth at outer apical angle. Beneath dull, the ventral segments 
exceedingly finely transversely strigose and with a few scattered punctures along the sides and on the last 
segment. 
Length 15 millim. 
Hab. Mexico, Puebla (Sallé), Tehuacan (Hége). 
This species, which belongs to the Huschides group, has no near ally, so far as I 
am aware. 
25. Asida subpilosa. 
Stenomorpha subpilosa, Sol. Ann. Ent. Soc. Fr. 1836, p. 490, t. 12. f. 10, 13°. 
Hab. Mexico !, Puebla (Sal/é), Tehuacan (/6ge). 
This fine large species was sent in plenty by Hoge. 
26. Asida pubescens. 
Closely allied to A. sudpilosa, and differing from it as follows:—The prothorax is a little more finely punc- 
tured, the elytra, instead of being clothed with long erect fulvous hairs, are almost imperceptibly 
pubescent; the femora and tibie coarsely rugulose, shining, and with scattered short fulvous hairs ; 
narrower and more parallel, and the upper surface almost glabrous. 
Length 25 millim. 
Hab. Muxico (Saillé). 
One example. This and the two following species (A. difficilis and A. thoracica) are 
closely allied, and till we obtain more material it is difficult to say whether they are 
really distinct. 
27. Asida difficilis. (Tab. III. fig. 11.) 
Oblong ovate, reddish black, shining. Head with scattered coarse punctures and an impression on each 
side in front; prothorax longer than broad, the sides rounded, equally narrowed in front and behind, 
anterior angles pointed, acute, and outwardly directed, hind angles rounded and almost obsolete, the 
base slightly rounded, feebly emarginate, and with a rather broad triangular impression in front of the 
scutellum, lateral margins crenulate, slightly reflexed and coarsely rugulose within, the disc with scattered 
fine punctures, the sides with coarse scattered impressions ; elytra long, rounded at the sides, a little 
narrowed towards the base, widest a little beyond the middle, base about as wide as the thorax, slightly 
rounded emarginate, and the margin a little raised, humeral angles obtuse, with widely scattered fine 
punctures, some very indistinct transverse scratches, and traces of two or three ridges, the usual marginal 
ridge quite obsolete; legs reddish brown, the outer apical angle of anterior tibise with a sharp tooth. 
Beneath shining; the ventral segments with scattered fine short transverse scratches, and a few small 
punctures towards the apex. 
Length 24-25 millim. 
Hab. Mzxico, San Luis Potosi, Hacienda de San Miguelito (Dr. Palmer). 
Var. Similar but with the thorax shorter, more convex, more rounded at the sides, and the hind angles 
obsolete; the elytra widened behind, &e. 
Hab. Mexico (Sail/é).
