thorace tenuissime granuloso, rnargine antico deflexo, vix 

 emarginato, pone oculos spina obtusa armato ; prothorace 

 capite latiori, angulis posticis obliquis ; elytris prothorace an- 

 gustioribus, sublente minute punctulatis; pedibus, mandibulis, 

 antennisque nigris ; tibiis antieis irregulariter crenulatis, inter- 

 mediis unidentatis, posticis tuberculo minimo instructis. 



Long. Corp. una. 1, lin. 5 ; mandib. lin. 5. 



Hab. Port Natal. 



Allied to C.faher, Thomson, but is at once distinguished by 

 its larger size and less glabrous character ; it differs further in 

 having the mandibles somewhat less curved, the sides of the pro- 

 thorax straighter, and the absence of the small spine at the pos- 

 terior angle. It belongs to that section of the African species of 

 Cladngnathus remarkable for the falcate form of the mandibles 

 (which in fully-developed males are only armed at the apex), and 

 in having the head furnished behind the eyes with a small obtuse 

 tooth. 



The female, as is frequently the case in other allied species of 

 this genus, is more polished than the male, and has considerable 

 affinity to the ? of C. qiiadridens, Hope, Cat. p. 14. 



With the exception of a small species of Dorciis, D. adspersus, 

 Boheman, recently described and figured by Professor Westwood 

 (Trans. Ent. Soc, 3rd Ser., i. 435, pi, xvi. fig. 6), this is the 

 only species of Lucanoid Coleoptera received in the numerous 

 collections that have of late been transmitted to us from that 

 rich entomological district of Africa, Port Natal. It appears in !-^^^]^3^ 

 some of the continental cabinets under the manuscript name of 

 C. Vescoi.

The above insect, unique in the Hopeian Cabinet, was captured 

 with other interesting species by W. Griffith, Esq., F.L.S., in the 

 Assam district, and placed by the Rev. F. W. Hope in his Cata- 

 logue together with Lucanus bulbosus (also described in Tr. Linn. 

 Soc. xviii. 589), in the sub-genus Macrognathus, immediately 

 preceding the sub-genus Platyprosopus, both of which sub-genera 

 appertain to the family Dorcidce, and are respectively identical 

 with the genera Hemisodorcus and Eurytrachelus of Mr. Thomson's 

 " Catalogue of the Lucanidae." L. bulbosus, Hope, a not very
