less attenuate posteriorly. The form with the broader tarsal claws, from Arizona and 

 Mexico, therefore requires a new specific name ; it will probably have to be removed 

 from Gerceus. The single male seen has moderately long prosternal spines.

6 (a). Pseudopentarthrum caudatum, sp. n. (Tab. XX. fig. 34.) 



Narrow, conico-cylindric, convex, shining ; nigro-piceous or black, the antennae, tibiae, tarsi, and the explanate 

 apical margin of the elytra, more or less ferruginous. Head unimpressed, very sparsely punctate ; rostrum 

 i extremely short, broad, sparsely punctate, transversely depressed at the apex. Prothorax slightly broader 

 than long, constricted and much narrowed anteriorly, closely punctate. Elytra very little broader than 

 the prothorax, perceptibly widening posteriorly, the outer margin with a blunt tooth -like projection 

 towards the apex, and the apical margin obliquely explanate from a little beyond this to the slightly 

 dehiscent sutural angle (the margins of the elytra thus appearing narrowly excised before the tip) ; 

 rather coarsely punctate-striate, the interstices flat, finely uniseriate-punctate.
