Dll. F. LEUTIINER ON THE ODONTOLABINI. 423 



2 



Major Parry confused two species under the name of ^. cingulatus. One occurs in 

 Malacca and the other in Siam (Laos). The former agrees perfectly well with his 

 fig. 3, and the latter with part of his description : — " Xigro-castaneus, nitidus, sub- 

 parallelus, elytris singulis vitta obliqua flava ab humero ad apicem notatis." 



The original, from which the above-mentioned figure was taken, was admirably 

 painted by Migneaux, rather above the natural size, and came into possession of Major 

 Parry through the agency of the late Count Mniszech, who did so much for the study 

 of the Lucanidae. It agrees perfectly with the type from the collection of Count de 

 Castelnau, which was kindly lent me for examination by its present owner, Herr van 

 Lansberge, and thus enabled me to clear up all doubts relating to this species, and to 

 make a careful description of it. Unfortunately the specimen remains unique, and the 

 male is still unknown ; but it appears to be most nearly allied to Gestro's Neolucanus 

 muntjac, from Borneo. 



The other species from Siam, which I propose to call N. parryi, is allied to N. casta- 

 nopterus, Hope, and N. swinhoii. Parry.
