290 Appendix to the Proceedings 



third striae nearly as far as on the fourth, only sloping very 

 slightly towards the suture, while in N. Championi the fourth 

 goes a good deal beyond the third. The posterior markings 

 are the same as in N. Championi, but are narrower, and conse- 

 quently appear almost interrupted where they advance at the 

 third stria and retreat at the fifth. They both have the elytra 

 very finely transversely aciculated, but the aciculations are finer 

 on intermedia than Championi, the power of lens which shows 

 them in the latter scarcely showing them in the former. In 

 other respects they correspond. 



There is yet another species which I have no doubt belongs 

 to this section, and which I would name quadrimaculata ; but, as 

 yet, I have only received a broken specimen, wanting both head 

 and thorax, and am therefore unable to describe it. It has two 

 large yellow patches on each elytron, the basal nearly round, 

 and the apical transversely oblong, both with very slight traces 

 of jagged edges. 



2nd Subgenus. Belonognatha, De Chaud. 



As mentioned under the last genus, I have slightly relaxed 

 Chaudoir's characters to give admission to the following species. 

 He describes the labrum as " very long, canaliculated at its ex- 

 tremity, strongly rounded and emarginate in the middle." I 

 retrench the latter half of these characters. In my species the 

 labrum is " very long and canaliculated at its extremity," but it 

 is not " strongly rounded and emarginate in the middle." The 

 only other character in which mine differs is, that while in his 

 the anterior tibiae are furnished with a single terminal spine, 

 the intermediate and the posterior with the two usual spines, 

 and the third and fourth joints of the anterior tarsi subcordi- 

 form, in mine the external spine of the anterior tibiae is small, 

 but still not wanting, and the joints of the anterior tarsi are 

 not subcordiform. In other respects the characters agree. 



1. B. rugiceps, mihi. 



Parum convexa, nitida, picea; capite creberrime rugoso; tho- 

 race late marginato, marginibus reflexis et testaceis; elytris 

 piceo-virescentibus, striato-punctatis, interstitiis convexis, 

 apice oblique-truncato, fortiter sinuato, marginibus testaceis, 

 singulis macula basali irregulari, et fascia interrupta apicali 

 testaceis ornatis ; antennis, ore, pedibusque testaceis. 



Long. 4 lin., lat. If lin. 



In coloration and general appearance very similar to Nycteis 

 Championi; slightly convex, piceous; the elytra pitchy black,
