to the ninth more or less transverse, the tenth forming a round com- 

 pressed club. Labrum small, entire. Palpi rather short, filifomi, the 

 last joint subcylindric. Mentum very transverse. Prothorax elon- 

 gate, with nearly parallel, slightly margined sides, constricted a little 

 at the base, produced anteriorly into a broad lobe overhanging the 

 head. Elytra lengthened, parallel, very convex. Legs short ; posterior 

 coxae distant; femora strongly grooved beneath for the reception of 

 the tibiae ; tibiae enlarged at their extremity, without spurs, ciliated 

 on their external margin; tarsi slender, the three basal joints very 

 short. Prosternum produced. The first two abdominal segments larger 

 than the others. 



Although the second abdominal segment is fully as large as the 

 first, yet, as they exceed the remainder, this genus cannot be placed 

 in any group in which the segments are equal ; otherwise, as its 

 posterior coxas are not contiguous, it might be associated with 

 Pycnomerus, Apeistus, &c. In its scaly pubescence it differs from 

 Bothrideres, Sosylus, and all the genera of that group (and the cha- 

 racter, as well as the absence of vestiture, like the sculpture, appear 

 to me to be of importance in this family). The antennae, described 

 as ten-jointed, may probably have eleven, the club being composed 

 of two, soldered together. In the figure eleven joints are given, 

 but the third should be united with the second. 



Asprotera inculta. (PI. VI. fig. 3.) 



A. elongata, cylindrica, fusca, supra albido-squamulosa ; elytris seriatim 

 punctatis, interstitiis squamulosis. 



Hah. Natal. 



Elongate, cylindrical, dull brown, furnished above with stiff whitish 

 scale-like setae ; head coarsely punctured, with few scales ; prothorax 

 strongly and thickly punctured, with numerous scales between them, 

 the anterior margin on each side obliquely grooved; scutellum very 

 small; elytra very coarsely seriato-punctate, the alternate interstices 

 with a more closely set row of scales than the intermediate ones ; an- 

 tennae not longer than the breadth of the head, reddish-brown ; legs 

 reddish-brown ; body beneath dark brown, coarsely punctured. Length 

 31 lines. 



Penthelispa [Colydiidae]. 



Head small, slightly dilated below the eyes. Antennae short, stout, 

 eleven-jointed, the last two forming a short ovate club. Eyes round. 

 Mandibles bidentate at the apex. Maxillary palpi robust, the terminal 

 joint broadly ovate, the labial smaller. Maxillary lobes short, ciliated, 

 somewhat falcate, the inner narrower. Labium very transverse, 

 rounded anteriorly, and finely ciliated. Mentum subquadrate, its an- 

 terior angles rounded. Prothorax subquadrate, scarcely emarginate in
