under sides) with a dense pubescence : from the centre of the third 

 proceeds the base of the ultimate joint, which is long, attenuated, 

 slightly inflected, and gradually dilated into a globular inflation com- 

 pletely concealing from above the apical claw ; this claw is bifid, being 

 armed at the base of its inner surface with a small tooth-like projection. 



This genus approaches, in the form of its thorax, to Tetragonotes 

 and Octogonotes : from the latter it is separated at once by the elongated 

 form of its palpi ; from the former it abundantly differs in its trans- 

 verse and more distinctly hexagonal form of thorax. 



The parallel and depressed form ofPhcedromus abundantly separates 

 it from all other allied genera.

Oblong-ovate, depressed, parallel, impubescent, black, shining. 

 Head transverse, very slightly produced, and depressed almost at 

 right angles to the plane of the thorax ; immediately above the base 

 of the antennae is a Y-shaped carination, extending obliquely towards 

 the inner margin of the eyes, and containing within it (when viewed 

 under a high magnifying power) a minute longitudinal fovea, which 

 connects it with a broad transverse and tolerably distinct depression 

 extending between the upper margins of the eyes ; eyes large and 

 prominent, extending laterally beyond the anterior angle of the 

 thorax ; the surface finely punctate, glabrous, black. Thorax broader 

 than the head, transverse, the anterior angles obsolete, but subacute ; 

 the sides (which are submarginate) are produced laterally into a 

 distinct and prominent angle ; behind this angle, which is antemedial, 

 the lateral margins slightly approach one another towards the base ; 

 at the base is a broad but very shallow transverse depression, which 

 extends obliquely upwards towards the anterior angles ; the surface 

 is impunctate and glabrous, of a flavous colour. Scutellum small, 

 fuscous-black. Elytra slightly broader than the thorax, depressed, 

 parallel, and rounded at the apex, punctate-striate, the striae being 

 subobsolete ; at the shoulders (between the fifth and seventh striae) 

 is a longitudinal depression; at the apex both the striae and the 

 punctures are obsolete. Antennce robust, subincrassated near the
