Cladognathus Senegalensis, Klug. 

 Lucanus Senegalensis $, Klug, Erm. Reis. Atl. 38, 103. 



Dr. Burmeister in his Handbuch der Entoniologie, v. 371, 

 gives this insect as synonymous with Lucanus Jniilopus $ , 

 Swederus (Act. Holm. 1787, iii. 18G, tab. viii. fig. 3); in this 

 I do not feel disposed to agree, since Swederus describes the 

 prothorax of his species as " lateribus subrotundatis," and figures 

 the four posterior tibiae as being unarmed — characters quite at 

 variance with the true Lucanus Senegalensis of Dr. Klug, a spe- 

 cimen of which from my own collection I have recently compared 

 with the typical insect in the Berlin Museum. This species is 

 readily distinguished in having the posterior angle of the pro- 

 thorax strongly emarginate, as well as the anterior angle of this 

 emargination being armed with a small acute spine ; hence Mons. 

 Gory applied the specific epithet of blsphwsus to the female 

 (according to a specimen so ticketed in the Oxford Museum). 

 The mandibles are nearly straight in all their different developments, 

 and the four posterior tibiae are armed each with a single spine. 

 As regards the veritable Z, Antilopus of Swederus, I am inclined, 

 from the description as well as from the figure, to refer it to 

 Lucanus quadridens, Hope (var. minor), with which it agrees in 

 the form of the mandibles (representing evidently those of an 

 undeveloped male, and characterized as such by the description 

 ** mandibulis capite vix longioribus"), in the posterior angles of 

 the thorax being rounded, and in the absence of the spines from 

 the four posterior tibiae ; although I must remark that in fully 

 developed individuals a minute tubercle is occasionally seen on 

 the intermediate tibiae. These spines or tubercles on the tii)iae, 

 however, are, as I have already had occasion to state, most 

 capricious, depending considerably, as to their size, and even for 

 their very existence, on the maturity of growth the insect may 

 arrive at, and can in no way be relied upon either specifically or 

 generically. 



In respect to the L. Antilopus, Burm., Hand, der Ent. v. 371, 

 this insect may possibly be identical with L. Senegalensis, Klug, 

 but as no mention is made of the posterior angles of the prothorax 

 being rounded or emarginate, or of the existence or non-existence 

 of the spine alluded to by Dr. Klug, it is dilHcult to fix exactly 

 the species to which it ought to be referred. If identical with 

 Senegalensis, Khig, it certainly is not the Antilopus of Swederus; 

 and should it be a more fully developed specimen of Antilopus, Swed., 

 (as the mandibles are described as being as long as the head and
