Explanation of Names
Pachybrachis brevicornis Fall 1915
Identification
Robust, yellow, with more or less heavy fuscous standard markings; eyes moderately distant, front with ocular lines; antennae unusually short; elytra strongly striate; front claws of male not appreciably enlarged. (Fall 1915)
Elytra diffusely punctate in a not very large basal-sutural triangle, elsewhere with distinct striae which are rather strongly impressed laterally, the fifth and sixth more or less broken or irregular at middle, the eighth with a subbasal dislocation; marginal interspace impunctate; shield conspicuous, elongate triangular.
The color may be described as yellow with more or less heavy confluent standard spots which vary from brown to nearly black; or as brown or blackish with the basal margin, some short spurs extending backward from it, two short interrupted lateral transverse fasciae, the shield, and the apex, yellow. (Fall 1915)
