40 MANDIBULATA. — COLEOPTERA. 



apex : head intlexed, narrower than the thorax, narrowed anteriorly : ei/es 

 lunate: ^//orrt.r somewhat semicircular, truncate in front: bodi/ slender-ovate, 

 flat on the back : scutcUuvi distinct : legs moderate ; Ubicc slender with short 

 spurs at the apex; iarsi with entire johits. 



The integrity of the joints of the tarsi forms a prominent dis- 

 tinction of tlic insects of this genus ; to which may be added the 

 nearly filiform palpi, the terminal joint of the maxillary ones being 

 nearly cylindric, and slightly acuminate ; the mandibles are bifid at 

 the apex, &c. 



fSp. 1. fuscus. Fusco-piceus pubescens, evidenfiiis 'rugoso-piinctatus,ore,anten-' 

 nis, pedibus ehitroi'umque limbo testaceis. (Long. corp. 1 — 2 lin.) 



Ha. fuscus. G;iUenhal, F. S- iv. 518. — Curtis. i Guide. — Ha. bipunctatus, var. 

 Pa2/!c. F. S. ii. 180. 



Pitchy-brown, pubescent, distinctly rugose-punctate : mouth and palpi pale 

 testaceous : thorax short, with a deep fovea on each side at the base: elytra 

 with the anterior limb broadly, and the lateral one narrowly and obscurely 

 testaceous : legs elongate, entirely pale testaceous ; the femora compressed; 

 antennse also pale testaceous. 



I believe a specimen of the above species was taken flying, in the 

 New Road, near the Regent's Park, many years since. 



Genus CCCCLIV. — Orchesia, Latreille. 



Antenna; with the eight basal joints short, obconic-cylindric, a little broadest 

 at the apex, the third longer than the foUowhig, the seventh and eighth 

 rather stouter than the preceding, the three terminal ones abruptly larger, 

 forming an oval, acute, club. Palpi unequal ; maxillary large, the second 

 and third joints produced within, the apical one much larger, elongate- 

 obtrigonal ; labial filiform : mandibles short, notched internally : head 

 inflexed : ei/es elongate : thorax somewhat semicircular, with the posterior 

 angles acute : elytra rigid, elongate, narrow: back flat: legs slender, poste- 

 rior saltatorial ; tibice simple, posterior short, with very long spurs at the 

 apex, serrated externally ; tarsi elongate, the four anterior with the penul- 

 timate joint subcordate, emarginate above. 



The elongate-serrated spurs with which the apex of the short pos- 

 terior tibiae of the insects of this genus is armed, combined with the 

 abruptly clavate antennae, subsecuriform maxillary palpi, their salta- 

 torial habits, &c., are sufficient to point out the peculiarities of this 

 genus from its aUies. The species reside in fungi, boleti, &c., and 

 evidently lead the way to the insects of the next family.
