With Descriptions of the New Species. 185 



the rains in 1886 and which he has kindly given to me, 

 I refer, with but slight hesitation, to this species; it 

 agrees fairly well with Westwood's description and figure 

 (Thesaurus Entom., p. 44, pi. 13, fig. 10) except that the 

 colour is piceous black, the thorax rather broader behind 

 and more finely punctured, the abdomen very deeply and 

 broadly impressed, the anterior tibiae, show no indication 

 whatever of a third tooth and the posterior tibiae are 

 strongly dilated on the inner side from the middle to the 

 apex, the dilatation commencing abruptly and forming an 

 acute angle, and very similar to that shown in Westwood's 

 figure (1. c. fig. 3) of C. Irunneus. As the chief of these 

 points of difference are evident male characters I infer 

 that Schaum's original type specimen, from which West- 

 wood's description and figure are taken, is a female 

 example, and that the male sex was unknown to either 

 of them. 



26. C(ENOCHILUS PYGIDIAL1S, n. sp. 



Elongatus, nigro-piceus, sub-nitidus ; subtus rufo-piceus ; capite 

 rugoso-punctato ; thorace sub-rotundato, postice truncate, crebre 

 punctate; elytris tri-sulcatis, cribrissime aciculatis, lateribus punc- 

 tatis ; pygidio transverse carinato ; tibiis anticis dilatatis, obtuse 

 dentatis. 



Long. 16 millim. 



Elongate, piceous black, slightly shining, the pygidium, underside 

 and legs reddish piceous and more shining. Head closely covered 

 with coarse confluent punctures and with a rather strong transverse 

 basal ridge, clypeus widened in front, with the angles rounded and 

 the apical margin slightly emarginate and reddish. Thorax strongly 

 rounded at the sides, widest just behind the middle, where it is a 

 little broader than long, basal margin straight, with the lateral 

 angles strongly rounded, very closely punctured and with an im- 

 pressed median line extending from near the base to a little beyond 

 the middle, a deep transverse fovea on each side at the base. 

 Scutellum convex, closely punctured and very acute at the apex. 

 Elytra very densely and irregularly aciculate and punctured, the 

 base and sides more distinctly punctured, strongly trisulcate on 

 the disk and with a deeply impressed line above the lateral sinus, 

 rounded at the apex with the sutural angles obtuse. Pygidium 

 divided by a very strong transverse ridge in the middle, the upper 

 portion very closely and finely aciculate and with a small fovea on 

 each side at the base, the lower portion irregularly but not very
