6 MANDIBIJLATA. COLEOPTKIIA. 



crenulated ; the disc longitudinally elevated and Ibveolated : elytra very 

 convex, each with three elevated lines, and nine striae composed of 

 punctures, each carina being separated by two stria : legs, and two basal 

 joints of antennie, dull black ; rest of antennte deep velvety black. 



Rare near London; frequenting sandy places: I liave taken 

 specimens on Hampstead-heatli in April, where it has subsequently 

 been captured by Mr. Ingpen : it has also occurred near Norwich 

 and Burnham, in Norfolk ; near Liverpool, and on Blackheath.

Genus CCCCXXIV. — Hvpophl^us, Fabricius. 



Antennw 11-jointed, short, compressed, gradually thickening from the third 

 joint, the fifth joint to the tenth perfoliate, compressed, seraiglobose, with 

 the apical angles acutely prominent, producing a serrated appearance ; the 

 terminal joint short, ovate. P«//ii 4, unequal ; the maxillary with the ter- 

 minal joint large, ovate, acuminate : mentum short : body linear, glabrous : 

 head prominent, large : eyes reniform : thorax elongate, quadrate, margined : 

 legs short, stout ; tibiae distinctly increasing from the base to the apex, 

 which is simple ; tarsi heteromerous. 



The short, 11-jointed, compressed antennae of this genus, which 

 are inserted on the lateral margins of the head, and are distinctly 

 serrated on each side, with the elongate linear or cylindric body, 

 elongate, or subquadrate, thorax, exclusively of other less evident 

 characters, readily point out the distinctions of this genus, of which 

 the species are found beneath the bark of trees. 



tSp. 1. castaneus. Brunneo-castaneus nitidus, crebre punctatus, ihorace elongate , 



elytris subtiliter punctato-striatis. (Long. corp. 2 — 2h lin.) 

 Hy. castaneus. Fabricius. — Steph. Catal. 241. No. 2412. 



Chestnut-brown, shining: head obscure castaneous, thickly punctured; 

 mouth pale : eyes black : thorax elongate, linear, deep shining chestnut, and 

 very thickly punctured : elytra pale shining castaneous, rather faintly 

 punctate-striate, with fainter punctures in rows between the striae: legs pale 

 rufo-testaceous : antennae dull chestnut. 



The only examples I have seen of this species were captured 

 " beneath the bark of an elm near Plymouth."" — Dr. Leach, who also 

 obtained a specimen for Mr. Bydder.
