minent teeth, which are curved upwards ; there is a hollow 

 between these, and the margin is semicircular; behind the 

 thoracic truncature there are about four rows of small teeth 

 running across from side to side; the posterior part of the 

 thorax is finely granulose or papillose. Scutellum small and 

 triangular. Elytra twice and a half the length of the thorax, 

 punctate in lines, many of which are irregular. There are the 

 faint traces of three costse ; the apex declines rapidly, and is 

 rounded at the margin ; the sutural line and the margin are 

 both raised at the apex, so that on each elytron they include a 

 slightly depressed, coarsely punctate space, although scarcely so 

 decided as to be called a truncature. The underside is not 

 quite so dark as the upper. 

 A single specimen. 



SiNOXYLON, Guer. 

 1 . Sinoxylon pubescens. 



Piceo-fuscura, pubescens ; elytris sexdentatis, sutura sine dente ; 



subtus dilutius, pedibus piceo-testaceis. 

 Long. 3^ lin., lat. li lin. 



Of the type of S. sexdentatum, but nearly a third larger. 

 Piceous brown, clothed with a short, pale griseous pubescence 

 close and thickly applied on the sides and back part of the 

 thoi-ax and on the underside ; fine and woolly hairs sparingly 

 scattered over the elytra. Antennae and parts of the mouth 

 testaceous. Head black and finely granulose ; there is a narrow 

 ridge or edging along the part that lies next the thorax; a 

 transverse slightly curved line runs from the anterior inner 

 angle of each eye, separating the epistome from the rest of 

 the head ; the labrum is covered with fulvous pile. The thorax 

 is widest at about a third from the base, the truncature of 

 which is pear-shaped with the apex in front, and truncate 

 with the anterior angles slightly produced, covered with tuber- 

 cles, which are largest at the sides ; the sides and back part 

 nearly smooth, covered closely with pale griseous pubescence, 

 among which appear a few scattered, very minute, but distinct 

 papillae. Scutellum small, subquadrate. Elytra with the apical 

 truncature very slightly oblique, almost vertical and even, as 

 if a part of the body had been cut ofi"; irregularly punctate, 

 faintly at the base, and gradually more deeply towards the 

 apex, where the punctuation is very deep, coarse, and rugose; 

 there are traces of the usual three costse on each elytron, which 

 respectively terminate at the apical truncature in well-developed 

 teeth ; the sutural margin and the external margin of the trun-
