£72 MANDIBULATA. COLEOPTERA. 



Sp. 2. ochropterus. Niger, subnitidus, elytris striatis subtestaceis, pedibus 

 nigro-piceis. (Long. corp. 4 lin.) 



N. G. ochropterus. Steph. Catal. 127. No. 1290. 



Head and thorax black immaculate, the posterior angles of the latter acute: 

 elytra striated, the interstices obsoletely punctured, pale testaceous: body 

 beneath black : legs pitchy-black, with the tibiae sometimes paler, or some- 

 what testaceous : antennas black. 



Known from the preceding, which it greatly resembles, by its dusky legs and 

 larger size. 



I have three specimens, which were found in South Wales. 



Sp. 3. rufipes. Oblongus, niger, nitidus, thorace lasvissimo immarginato medio 



latiori, elytris depressis punctato-striatis, pedibus rufis. (Long. corp. 3| — 4 

 lin.) 



El. rufipes. Fabricius. — N. G. rufipes. Steph. Catal. 127. No. 1291. 



Oblong glossy-black, slightly pubescent ; thorax shining, immarginate, broadest 

 in the middle, subpunctate: elytra scarcely broader than the thorax, with 

 the apex rounded, above a little depressed, punctate-striate, with the inter- 

 stices very obsoletely punctate : legs dull rufous, with the tarsi fuscescent. 



Rare ; especially near London : it is also found in the west of 

 England. " Woodland, Devon." — Dr. Leach. 



Sp. 4. Quercus. Oblongus-niger, elytris fusco-virentibus, thorace elongato pos- 

 tice Icevi, fronte prqfunde punctato, "pedibus fusco-testaceis, tibiis pallidis.

El. Quercus. Olivier, ii. 31. pi. 6. f. 60.— El. pallipes. Paykul, F. iii. 14. — 

 N. G. tibialis. Steph. Catal. 127. No. 1292. 



Oblong-black : forehead deeply rugose-punctate, slightly foveolate : thorax elon- 

 gate, finely punctured anteriorly, smooth posteriorly : elytra slightly acumi- 

 nated, moderately convex, of an opaque greenish fuscous, clothed with a fine 

 cinereous down, obsoletely striated, the interstices finely granulated; the 

 inflexed margin obscurely rufescent: legs fusco-testaceous, with the tibia? 

 pale : antennae black, with the basal joint piceous. 



The elongate thorax, dark legs, with pale tibiae, distinguish this from the 

 preceding insect. 



Found occasionally in woods near London ; the only localities I 

 know being those of Darenth and Birch-wood. 



Genus CCXXX. — Ctenonychus* mihl. 

 Antenna short? simple, pilose ; the basal joint elongate, slightly robust; second
