 oak) ; by Dr. H. L. Cliaudiiiiri and myself from the Darjiiiufr Di.strict (Senehal, ca. 8,000 ft., 

 and I'ashok 5,500 ft.) ; by ."\lr. S. \V. Kemp from the Kha.si Hills (Shillong 6,400 ft., and 

 MatloiiL'. 5,900 ft.) ; and by .\I. Vitalis de Salvaza from Tonkin (Lao Kay). 



One .specimen labelled • Darjeeling "' in the Van de PoIJ collecticm is only 28-:; mm. 

 hmg. All the remaining Himalayan .s])ecimens are 30 nxm. long or over. The .Manipur 

 specimen is 30 mm. long ; all the remaining .specimens found ea.st of the Darjiling Di.strict 

 are 29 mm. long or under. Although, therefore, occasional .specimens may transgress the 

 normal limits of the race characteri.stic of their locality, the validity of difference in size as 

 a distinction between (). canton, s. str., and its sub-.species convexijrons is confirmed. The 

 form of mentum, on the other hand, described as distinctive of the sub-species dunsiriensis, 

 does not a])])ear to be a good character, and although .specimens from the Dunsiri valley 

 range from 28 to as much as 31 mm. in length I think that they can best be regarded as 

 belonging to the sub-species converifrons.

One specimen from Laos, and two from Mt. Marapok, Dent Province, British Xorth 

 Borneo. Length 30-5-32-2 mm. 



In fresh specimens the anterior lower teeth each have their apices produced into a 

 sharp and slender point. The left outer tubercle is distinctly thicker at the base than in 

 the preceding species, but may point more deiinitely inwards than in the tvpe .specimen.

 One specimen from Singapore and a number from Borneo (Mts. Kinabalu and Marapok). 

 Length 33-5-38-0 mm. 



The anterior lower tooth on each side is much broader than the lowest terminal. Both 

 are snmll on the right mandible, but are perfectly distinct in fre.sh specimens.

A number of sjiecimens from .Mt. .Marapok. Dent Provijue, British Xorth Borneo; 

 and one from Mt. Kinabalu. l^ength 23-27 mm. 



The punctures in the lateral grooves of the elytra are variable, and 1 no longer think it 

 at all likely that oroleiiis. Smitli, will have to be recognized as a distinct variety.
