ENGID^. — RHYZOPHAGUS. 99 



which latter are ovate : legs moderate ; femora slightly elongate, subclavate ; 

 tibice simple ; tarsi distinctly four-jointed. 



It appears to me far more natural to place this genus near 

 Cerylon than amongst the Bostricidae, to which family it has 

 hitherto been referred ; the structure of its antennae, &c, and the 

 form of its body, with its general habit, being more intimately allied 

 to the genus above alluded to than to any of the Bostricidae. From 

 the other species of Engidae with the club of the antennae uniarti- 

 culate, Cicones may be readily known by the terminal (or tenth) 

 joint wanting a pointed appendage. 



fSp. 1. Carpini. Castaneo-niger, subpubescens, punctatus, elytris maculis aliquot 

 obscure aurantiacis, pedibus ferrugineis, antennis ochraceis. (Long. corp.

" Castaneous-black, sparingly covered with stiff yellow bristles : head minutely 

 and thickly punctured : thorax with two obtuse elevations near the middle, 

 behind rugosely punctured : elytra very convex, with three elevated longi- 

 tudinal lines and a punctured stria on each, more castaneous than the thorax, 

 having an oblique spot near the anterior angle, three near the middle, a 

 transverse lunulated mark, and another near the apex, dull orange: an- 

 tennae ochraceous : legs pilose, ferruginous." — Curtis, I. c. 



Taken beneath the bark of the hornbeam in Epping Forest, in 

 March, 1826. 



Genus CLIX. — Rhyzophagus, Herbst. 



Antenna much shorter than the thorax, the basal joint large, clavate; the second 

 much less, truncate; the third obconic, with the base narrower; the six fol- 

 lowing very short, coarctate, rather thickening exteriorly ; the tenth very large, 

 rounded, pilose, with an obscure rudiment of another joint at the tip. Palpi 

 very short, filiform : head exserted, suddenly contracted before the insertion 

 of the antennae : eyes small, globose : thorax subquadrate, its lateral margins 

 entire : body linear-elongate : elytra truncate : legs rather short ; tibiae broad 

 at the apex : tarsi, four anterior apparently pentamerous, the two posterior 

 tetramerous. 



Rhyzophagus is distinguished from Monotoma by having the 

 lateral margins of the thorax entire, as well as by less evident 

 characters, and from Cerylon and Synchita by the distinctly ab- 

 breviated, truncate, elytra ; the filiform palpi ; elongate-linear body, 

 the dissimilarity in the form of the head, &c. : — the species are found
