444 Mr. A. Murray on Coleoptera from Old Calabar. 



Subgenus 2. [Belonognatha), 



Elytra polished and shining, without aciculation or reticula- 

 tion. Body convex, and mandibles usually prominent and acute. 



This subgenus contains the species I have already described 

 under the names of Belonognatha rugiceps, obesa, and quadri- 

 notata, besides, doubtless, Chaudoir's species, B. pustulata, and 

 possibly King's Beleopterus cyanipennis. 



The characters of the new species lately received are as follow : 



2. N. intermedia J mihi. 



Valde affinis N, Championi, sed parum minor, labro magis elou- 

 gato et ad apicem canaliculato ; mandibulis acutioribus ; tho- 

 race minus transverso et postice angustiore; elytris apice 

 emarginatis sed non dentatis, angulis posterioribus rotundatis, 

 cum maculis anticis grandioribus et maculis posticis minus 

 continuis. 



Long. 3 lin., lat. IJ lin. 



Has very much the appearance of N. Championi, but, on com- 

 parison, is readily distingui^ed by the characters mentioned in 

 the above diagnosis. The insect is smaller, and the coloration 

 is the same, only a little darker. The labrum is longer, and 

 narrowed towards the point, where it is canaliculated. The 

 mandibles are more slender, more acute, less rounded on the 

 exterior, and narrower at the base. The head is narrower, and 

 is marked by a number of minute longitudinal wrinkles. The 

 thorax is not so transverse and is narrower behind, and the re- 

 flexed margin is not quite so broad. The elytra are rounded at 

 the posterior angles instead of being toothed, and the testaceous 

 markings on them are slightly different ; the anterior marking 

 is confined to the same striae, but is rather larger from the colour 

 running further on some of them ; it runs up on the second and 

 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
