126 MANDIBULATA. COLEOPTERA. 



The extremely prominent eyes of the insects of this genus 

 distinguish them from all the allied genera, except Philopedon, 

 from which they differ by having the third joint of the antennae 

 longer than the second, as well as by the less globose form of body, 

 general habit and manner: — they form a portion of the genus 

 Thylacites, as originally proposed, but from the type of that genus 

 being widely dissimilar, Billberg's name is liere employed. 



A. With the thorax truncate at the base. 

 a. Rostrum divided, as it were, from the head by a transverse striga. 

 Sp. 1. Coryli. Niger, squamulis densis fuscis cinereisque variegatus, suturd 

 basi nigra, antennis pedibusque, rufo-ferrugineis, Jronfe rostroque sulcato- 

 rugosis. (Long. corp. 2 — 3 lin.) 

 Cu. Coryli. Fabricius — Martyn, C. pi. 19./. 20. — Str. Coryli. Steph. CataL 

 175. Nc. 1783. 



Black, variegated with fuscous and cinereous scales : rostrum black at the apex, 

 unequal, rugose and canaliculated : head short, and considerably wrinkled 

 longitudinally, with a deeper impression in the middle : eyes very prominent : 

 thorax thickly rugose-punctate, with three obscure fuscescent dorsal lines: 

 elytra pubescent, more or less variegated with fuscous and cinereous, and a 

 few whitish scales, luith the basal half of the suture black, rather deeply punc- 

 tate-striate, the interstices convex, and nearly smooth : body beneath piceous, 

 with white scales : legs stout, rufo-ferruginous : antennae the same. 



Extremely abundant on the nut-tree in June within the metro- 

 politan district, and I believe equally common throughout the south 

 of England. "Swansea." — L.W.DUlwyn,Esq. "Netley." — Rev.

Sp. 2. rufipes. Niger, squamulis densis fuscis cinereisque variegatis, antennis 

 piceis, pedibus rufis,fronte haud sulcata, puncto impresso. (Long. corp. 1^ 

 lin.) 



St. rufipes. Steph. Catal. 175. No. 1784. 



Black, densely squamose : head rather deeply puntate-rugose : rostrum with a 

 deep impressed fovea, not sulcate : thorax finely and not very thickly punc- 

 tured : elytra rather deeply Ytunctate-striated, the interstices flat, densely 

 clothed with fuscescent scales, more or less variegated or tessellated with cine- 

 reous; the suture concolorous : antennae piceous : legs rufous. 



Found in woods in the vicinity of the metropolis, not very common. 



Sp. 3. Asperifoliarum. Niger, dense cinereo squamosus, thorace lineis tribus 

 fuscis ; elytris striatis albido fuscoque marmoratis, antennis piceis, pedibus 

 rufescentibus. (Long. corp. 2— 2g lin.)
