BOSTRICHIDJE. — TRYPODENDRON. 353 



posed in striae : legs rufo-piceous, tibiae and tarsi paler ; club of the antenna? 

 rufescent. 

 This singular insect agrees with the Apate substriata of Paykul, excepting in 

 not having the puncta on the elytra disposed in striae, and in being less 

 pubescent. 



I have a pair of this species from the New-fores t. 



Genus CCLXI V. — Trypodendron * mihi. 



Antennae rather slender; the basal joint very long, slightly bent, clavate; the 

 second robust, obconic ; the third to the eighth very short, coarctate ; the re- 

 mainder forming an ovate compressed, triarticulate, obliquely acuminated 

 club. Palpi very short : mandibles acute, dentate : head small, deflexed : eyes 

 sublunate: thorax very large, gibbous, wide anteriorly: body short, sub- 

 cylindric : tibiae expanded at the apex and denticulated ; tarsi very long, 

 slender, simple, pentamerous. 



The solid capitulum of the antennae distinguishes this from the 

 preceding genera, as does its acute termination from the following, 

 excepting Hylesinus, from which it differs in having the tarsi 

 simple : — the species are exceedingly destructive to trees, per- 

 forating deeply into the solid wood, but fortunately they are rare in 

 Britain. 



Sp. 1 . dispar. Nigro-piceum, longiiis pubescens, antennis tibiis tarsisque testa- 

 ceis, elytris brunneis, punctato-striatis, apice dilutioribus. (Long. corp. l| — 2 

 lin.) 



Bo. dispar. Illiger.—Steph. Catal. 144. No. 1454. 



Pitchy-black, clothed with a long griseous pubescence: thorax large, sub- 

 orbiculate, very convex in the female, anteriorly tuberculate: elytra brunneous, 

 distinctly punctate-striate, the disc convex, sloping from the middle to the 

 apex : femora piceous, with the apex testaceous : tibiae and tarsi of the latter 

 colour : antennae pale testaceous. Female much larger than the male, with 

 the thorax subglobose, the legs comparatively shorter, and the antennae more 

 slender. 



My specimens of this insect I obtained from Mr. Bydder, who 

 found them in the New-forest, near Lyndhurst.
