En 1870, dans son Revised Catalogue of the Lucanoid 

 Coleoptera; with Remarks oit the N ' omenclature, and J>. 

 criptions of New Species, le major Parry compléta en ces 

 termes les renseignements qu'il avait recueillis sur le 



D or eus (?) derelictus; il figure 

 l'insecte à la Planche II, fig. 3, 

 des Transactions de la Société 

 entomologique de Londres 

 (fig. 1), et il exprime des 

 doutes relativement à la légiti- 

 mité de son attribution à la 

 tribu des Dorcinae. 



(( Since the publication of my 

 description of tins singular 

 insect, of which the sex ap- 

 peared to me doubtful, I hâve 

 been enable by dissection to 

 ascertain beyond doubt that it 

 is a female. The strongly bi- 

 tuberculate head induced me formerly (with some hésitation) 

 to place it with the Dorcilœ, but I am now inclined, on 

 account of its uniform glossy and comparativolv impunctate 

 surface, coupled with the "form and slender character of its 

 legs, and its unarmed posterior tibias, to consider that this 

 species is perhaps more closely al lied to the C.ladognathinœ, 

 or to the Odontolabïnœ, the latter having the posterior tibia? 

 in both sexes unarmed. The singular anomaly of having the 

 posterior tibia?, unarmed in this sex of the Clado gnathinœ, 

 has fallen under my notice only in two species, Prosopocoilus 

 cavifrons and P. approximatus; nervertheless as a knowledge 

 of the maie sex can alone déclare its'true position, I prefer for 

 the présent to locate it temporarily in the fourth section of the 

 genus Dorcus, together with two other insects, the maies of 

 which are at présent unknown. »
