Obs. — Dr. Burmeister, probably in consequence of Mr. Mac 

 Leay having observed under the description of his /Egus chclifer, 

 " Lucanum Cancroidem, Fabricii, baud examinavi, at generi Dorco 

 potius pertinere videtur," has given this insect as identical with the 

 ^g. chelifer, Handb. d. Ent, v. p. 403. Not only, however, does 

 the specific name as well as Its position as the first species in the 

 genus prove that its mandibles agree with the generic description, 

 *' porrectse falcatae inermes," but the figure given by Mac Leay of 

 the maxillae oi /Egus chelifer, pi. 1, fig. 7, e, is destitute of a cor- 

 neous hook, I have not had an opportunity, it is true, of dissect- 

 ing the typical unique specimen of Cancroides in the Banksian 

 Collection, and can only therefore, from its close analogy with the 

 following species, conjecture that the mando of the maxilla of the 

 male is uncinated. 



Tlie Australian /Egus chelifer of Mac Leay is doubtless more 

 nearly allied to /Egus acuminatus and lunatus, Weber. This latter 

 species from Sumatra is considered by Dr. Burmeister (1. c.) as 

 identical with my /Eg. falciger (not fulviger) described in the 

 Ann. d. Sci. Nat. Sec. Ser. i. 118.
