HKLOl'ICE. — ERYX MYCETOCHARUS. SJ: 



Genus CCCCXLI. — Eryx mihi. 



AntennoE rather longer than the thorax^ the second joint minute subglobose, 

 the remainder obconic^ the third being rather the longest^ and the apical one 

 shortest^ more slender^ and subovate, with the apex acuminate. Palpi 

 unequal, maxillary with the terminal joint very large, obliquely truncate, 

 and securiform ; mandibles bifid at the apex ; mentum entire : head small, 

 deflexed: thorax transverse, semicircular, the base a little waved: body 

 ovate : elytra convex : wings ample : legs moderate ; tihice simple, with 

 spurs; tarsi heteromerous, the joints simple, with the apex of the terminal 

 slightly emarginate ; claws denticulated. 



Latreille arranges this genus with Helops, but from those insects 

 the totally dissimilar (and comparatively depressed) form of body, 

 combined with other discrepancies in the structure of the antennae 

 and palpi, as well as the denticulated claws, sufficiently remove it ; 

 as do its habit and economy, and also the bifid apex of the mandi- 

 bles, abbreviated antennae, &c., from Cistela, with which genus it has 

 been associated. 



Sp. 1. nigra. Niger suhnitidus, ore antennis pedibusque piceis, elytris obsolete 



itriatis. (Long. corp. 5 — 7 lin.) 

 Pyr. nigra. Degeer. — G. N. ater. — Steph. Catal. 245. No. 2442. 



Black, slightly shining ; clothed with a very short black pubescence, thickly 

 but rather obsoletely punctured : the elytra faintly punctate-striate, with 

 the interstices thickly but finely punctured: legs, antennsB, and mouth, 

 pitchy-black. 



Far from common in the vicinity of London, where it occasionally 

 is found beneath the bark of trees; about Walthamstow and at 

 Coombe-wood I have taken specimens. " Near Cambridge."" — Bev.

Genus CCCCXLII. — Mycetochauus, Latreille. 



Antenna; longer than the thorax, rather stout, pubescent, three basal joints 

 rather slender, the second abbreviated, the third elongate, the remainder 

 obconic, with the terminal one somewhat orbicular. Palpi unequal, the 

 7naa?i7/ar?/ with the terminal joint securiform ; the labial clavate, truncate: 

 mandibles with the apex bifid: jacntum entire : head short, small, rounded : 

 thorax transverse, subquadrate, broadest behind : body linear-elongate, 

 rather convex, pubescent : wings ample : legs moderate ; femora rather 

 stout ; tibia an4 tarsi elongate ; the latter heteromerous and simple : claws 

 denticulated.
