APHODIID/E. PSAMMODIUS. 211 



Cylindric, black, shining : clypeus somewhat emarginate, finely punctured, with 

 the anterior margin pale : thorax rather coarsely punctate, with two oblique 

 sulci on each side, one arising at the anterior angle, the other behind the 

 middle, and an abbreviated longitudinal one behind : elytra elongate, rather 

 deeply punctate- striate: abdomen black ; legs piceous. 



From Ps. porcatus this species may be known by its more elongate cylindric 

 form, and by the oblique abbreviated sulci on the lateral margins of the 

 thorax. 



A rare species, at least towards the eastern parts of Britain ; in 

 the western it appears to be more abundant. " Near Bristol and 

 Pentire Point, Cornwall. ,1 — Dr. Leach. 



B. With the thorax sulcated transversely.

Oblong, dull fuscous-black: clypeus angulated, deeply emarginated, convex, 

 the margins ferruginous, the vertex obliquely sulcated : thorax short, convex, 

 ciliated laterally and behind, with four transverse elevated coste, the two 

 posterior of which are sinuated and interrupted in the middle: elytra linear- 

 elongate, punctate-striate, the interstices thickly granulated : body piceous ; 

 antennae and legs somewhat ferruginous. 



The granulated interstices between the strise on the elytra at once separate this 

 species from the following. 



Also a local species ; found in the west of England : my speci- 

 mens were captured " Near Bristol." — Dr. Leach.

 vi. pi. 258. 



Ovate, '.black, shining : clypeus emarginated, rugose, rufo-piceous anteriorly : 

 thorax with five transverse ridges, the furrows between slightly crenated, the 

 posterior ones interrupted by a longitudinal fovea : elytra very convex, con- 

 siderably dilated behind, deeply crenate-striate, with the interstices flat and 

 smooth : body and legs rufo-piceous. 



Variable in colour : some examples being of a piceous or castaneous hue, de- 

 pending upon the state of maturity. 



Taken not unfrequently near Swansea in the summer, and 

 probably also in Suffolk. " On Crwmlyn Burrows ; — and towards
