and another in Epping Forest ; it has also occurred in the New 

 Forest, and in Norfolk. " Heniault Forest." — Messrs. Chant and

Genus CXLVIIL — Mycetophagus, Fahriclus. 



Antenna; scarcely as long as the thorax, gradually incrassated to the apex, the 

 five last joints forming an indistinct perfoliated club, the four basal joints of 

 which are cup-shaped, the last more or less elongate-ovate. Palpi with the 

 last joint rather incrassated, subtruncate: head small, triangular: eyes slightly 

 prominent : thorax transverse, rather convex, broadest posteriorly, and closely 

 applied to the base of the elytra, which are subovate : body ovate, slightly 

 convex : tarsi filiform, simple, four-jointed ; the males with the anterior three- 

 jointed only. 



The pretty genus Mycetophagus may be known by having the 

 capitulum of the antennse rather indistinct, and composed of five 

 joints ; the body oval, with the thorax as broad posteriorly as the 

 base of the elytra to which it is closely applied : — the species are 

 found in fungi during the spring and summer months, and occa- 

 sionally in the autumn ; most of them are local.

 4-punctulatus. Steph. Catal. 87. No. 943. 



Ferruginous : with the antennas black in the middle, the apex testaceous : head 

 with a deep impressed striga between the antennas : eyes blackish-brown : 

 thorax black, narrow anteriorly, the base broad, the angles acuminated ; the 

 disc convex, finely punctured, with a deep rounded fovea on each side to- 

 wards the base; elytra closely applied to the base of the thorax, as in the 

 genus Amara ; slightly convex, black, or piceous, rather obsoletely punctate- 

 striated, each elytron with two testaceous-yellow spots, one large irregular at 

 the base, and a small truncate one towards the apex: legs pale testaceous. 



It varies a little : in some examples, the apical spot on the elytra is obliterated, and 

 in others the two spots are more or less united by a longitudinal flavescent 

 streak. 



Common in many places throughout the metropolitan district, fre- 

 quenting rotten trees, fungi, &c, in the beginning of summer.
