Garoet Preanger, 4,000-5.000 ft. ; G. Tji Salimar, W. Preanger, ca. 3,000 ft. ; Boeloe 

 Lawang Res. Pasoeroean. Length 27-32 mm. 



This species appears to be very common in Java, where it probably replaces the 

 preceding one. It seems to be rare in Sumatra and Borneo. It has not been recorded 

 from the Malay Peninsula. 



Aceraius perakensis, Kuweit. 



Aceraius perakensis, Kuwert, 1898, p. 308. 



Aceraius perakensis-hlaevimargo, Gravely, 1914c, pp. 229 and 235. 



A number of specimens from Mt. Kinabalu. M. Guy Babault has presented a 

 specimen from near Dolok-Baros, Médan, Sumatra. Length 34-40 mm. 



A. laevimargo, Zang, appears to be identical with the species which I previously 

 separated as A. perakensis. 



Aceraius tricornis, Zang. 



Aceraius tricornis + kuwerti, Zang, 1903a, p. 339. 



Aceraius tricornis + kuwerti, Gravely, 1914c, p. 235, text-rig. 4 B, pi. xi, fig. 31. 



Two specimens from Mt. Maropok, and a number from Mt. Kinabalu. Length 46-0- 

 52*5 mm. 



The characters by which A. tricornis is separated from A. kuwerti prove to be variable, 

 and the second name must fall. 



Aceraius laniger, Zang. 



Aceraius laniger, Zang, 1905«, pp. 191-192. 

 Aceraius laniger, Gravely, 1914c, p. 234. 



Three specimens from Borneo, two being from Mt. Kinabalu. Length 54 - o-56 - 5 mm. 

 The characters distinguishing this species from the last, small though they are, do not 

 appear to vary. 



Aceraius mbschleri, Kuweit. 



Aceraius möschleri, Kuwert, 1898, p. 344. 



Aceraius möschleri, Gravely, 1914c, pp. 229-230, pi. xii, fig. 33.

Aceraius illegalis, Kuwert, 1898, p. 345.

 (Bedagei Interior, ca. 600 ft. ; Tandjong-Djati, Ranau, Palembang, ca. 2,000 ft. ; S. E. 

 Serdang, E. Coast, ca. 1,000 ft.) ; N. Nias (Hili Madjedja and G. Madjeja) ; Middle Nias
