TRIGONOSCUTA Motschulsky. 
A genus known by a single species only, from California. The fossil 
species which I place here can hardly have found its proper home, though it 
would seem to be not far removed from it. The stoutness of the rostrum 
and want of obliquity of the antennal scrobes, with its more compact form 
and the greater transverseness of the thorax, would seem to separate it, 
while the form of the femora, the relation of the cox, the breadth and 
convexity of the intercoxal process of the hind legs, the form and size of the 
second abdominal segment, and the course of the suture separating this from 
the first segment are points of particular resemblance.

Play hig. 3: 
Body stout, compact, a little more than half as long again as broad. 
Head small, finely punctate; eyes large, transversely broad-oval; antennal 
scrobes scarcely oblique; rostrum shorter than the head, rather stout as 
seen laterally, sparsely and not very finely punctate. Prothorax apparently 
fully twice as broad as long, densely and rather finely punctate; in front, 
finely and transversely striate. Elytra coarsely punctato-striate, the inter- 
spaces with a single row of finer circular puncta, separated from each 
other in the same row by half their diameter Anterior coxe attingent; 
middle. pair separated by a very narrow space, less than one-fourth the 
diameter of the coxal cavity; hind pair very widely distant, nearly twice 
the diameter of the coxal cavity. Femora large, long, clavate, punctate. 
Tibize moderately slender, not flexed. First and second abdominal seg- 
ments long, separated by a sinuous suture; whole under surface densely, 
uniformly, and rather coarsely punctate. 
The specimen shows at the same time dorsal and ventral aspects, but
