506 SUPPLEMENT 
Ologlyptus graciliformis (p. 68). | 
To the Mexican localities given, add :—Mexico city, Tula and Pachuca in Hidalgo 
(Hoge). 
2(a). Ologlyptus hebes. (Tab. XXII. fig. 23.) 
Very robust, broad, dull black, thickly covered with a brownish, agglutinated, earthy coating, and with short, 
scattered, coarse scaly hairs. Head coarsely punctate; antenne short and stout, clothed with very 
coarse, short hairs, the eighth and ninth joints transverse ; prothorax broader than long, not wider at the 
base than at the apex, the sides rounded at the middle, converging in front and behind, and sinuous 
before the base, the latter subtruncate, the apex deeply emarginate, the anterior angles prominent but 
obtuse, the hind angles prominent, rectangular, the disc feebly convex, the lateral margins raised and 
somewhat expanded, the entire surface very densely, coarsely punctate, each puncture bearing a coarse, 
decumbent, scaly hair ; elytra flattened on the disc, widest a little behind the middle, slightly rounded 
at the sides, considerably narrowed in front, and produced at the apex, with a stout marginal carina 
extending from the obtuse humeri nearly to the apex, a similar carina on the middle of the disc, the two 
almost connected posteriorly, and a short carina midway between them, the rest of the surface (and 
epipleure) with scattered granular elevations, each elevation bearing a short, semi-erect, scaly hair ; 
beneath thickly punctured, each puncture bearing a coarse, decumbent, scaly hair ; prosternum depressed 
in the middle between the coxz, declivous behind; middle coxe with a small, but distinct, trochantin ; 
legs exceedingly stout, clothed with very coarse, scaly hairs; anterior tibie with a short tooth at 
the apex. 
Length 19-24, breadth 10-114 millim. 
Hab. Mexico, Villa Lerdo in Durango (Hége). 
Nine examples. This species is perhaps nearest allied to O. graciliformis, from 
which it differs in its large size, robust form, and very stout limbs. The middle coxal 
cavities are not closed externally and they have a small but distinct trochantin. 
Ologlyptus canus (p. 68). 
To the locality Mexico, add :—near the city (Hége). 
Four examples. 
Ologlyptus bicarinatus (p. 69). 
This species, which is still unique, would be better placed in Asida, the trochantin 
of the middle coxe being moderately prominent. 
Ologlyptus planatus (p. 69). 
In the description of this insect I have omitted to mention * that the ninth joint of 
the antenne is widened and strongly transverse, and very little narrower than the 
tenth, the apical three joints forming a sort of club. 
* The antenne are incorrectly drawn by our artist, Tab. II. fig. 16.
