thorace tenuissime granuloso, margine 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 anticis irregulariter crenulatis, inter-

Long. corp. unc. 1, lin. 5; mandib, lin, 5. 
Hab. Port Natal. 
Allied to C. faber, 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 
Cladognathus 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. quadridens, Hope, Cat. p. 14. 
With the exception of a small species of Dorcus, D. adspersus, 
Boheman, recently described and figured by Professor Westwood 
(Trans. Ent. Soc., 3rd Ser., i. 435, pl. 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 
some of the continental cabinets under the manuscript name of 
C. Vescoi.

Macrognathus Spencii, Hope, Cat., p. 6. 
bulbosus 8, var. min., Hope. 
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 Dorcid@, and are respectively identical 
with the genera Hemisodorcus and Eurytrachelus of Mr. Thomson’s 
“Catalogue of the Lucanide.” JL. bulbosus, Hope, a not very
