BOSTRICHID.E.-T-APATE. 35 L 



tennae, as well as the retuse, more or less dentate or eroded posterior 

 portion of the elytra, subquadrate thorax, the denticulated tibia?, &c. 

 distinguish this genus. A. muricatum being the typical species of 

 the genus Apate, as originally established by Fabricius in his 

 Systema Entomologise, it becomes necessary to employ his name for 

 the present genus. 



Sp. 2. sinuata. ? Plate xix. f. 6. — Nigro-picea, thorace muricato, elytrisfuscis 



postice retusis dentatis. (Long. corp. 3 lin.) 

 Ap. sinuata. Fabricius'? — Ap. muricatus. Steph. Catal. 144. No. 1452; ex- 



cluso synonymis. 



Pitchy-black : head very pilose : thorax anteriorly gibbous, with elevated muri- 

 cate tubercles, the hinder portion very smooth, slightly depressed on each^side 

 at the base : elytra irregularly and coarsely punctate, retuse behind, with one 

 small and two large tubercles on the disc of each, and the inner angle of the 

 suture behind slightly tubercular : legs piceo-testaceous : antennae rusty- 

 ochraceous. 



The only specimen I have seen of this insect was taken beneath 

 the bark of a tree in Epping-forest, and is in my collection. 



Sp. 1. muricata. Nigra, elytris reticulatis, postice retusis dentatis, thorace mu- 

 ricato gibbo. (Long. corp. 8 lin.) 



Ap. muricata. Fabricius, E. ii. 378. — Bo. terebraus. Olivier, E. 77. pi. \. f. 4. 

 — De. muricatus. Linne. ii. 562.?? 



Deep shining black: mouth with a dense fulvous pile : thorax somewhat opaque 

 gibbous, retuse in front, the sides muricate anteriorly, with several hooked 

 teeth : elytra deeply reticulated, each with three obscure lines, becoming ele- 

 vated posteriorly, and forming dentations towards the apex : abdomen clothed 

 with a fulvous pile: club of the antennae ferruginous. 



I possess a specimen of this insect — which at first sight resembles a large 

 Sinodendron cylindricum — taken about ten years since, at the foot of a poplar, in 

 the Isle of Dogs : — it is decidedly an imported species, being a native of the 

 West Indies and South America, and subsisting, as Pallas informs us, upon 

 the sugar-cane. Had Mr. Curtis taken the pains to examine the descriptions of 

 Linnaeus, Fabricius, &c. both of Apate and Sinodendron, he would scarcely have 

 given the confused account he has of the localities of this insect and Sinoxylon 

 bispinosum, which he has rendered still more inaccurate by copying De Jean's 

 reference to Olivier, as synonymous with the insect last mentioned : — the 

 Linnaean insect can scarcely be the same as he says, the size of Dermestes (Ne- 

 crobia) violacea.
