380 Longicornia Malayana. 



iium and third and fourth segments, except in the middle, white; 

 legs and antennae black. 



Length 6 lines. 



This species, described by M. Thomson from individuals from 

 Japan, agrees exactly with my Malacca specimens, and also with 

 another from India. Glenea Can'td'ia from Bombay, and G. Mou- 

 liotii from Laos, are probably varieties, at least there are interme- 

 diate forms in the British Museum, one of which, from Siam, has 

 the elytra almost entirely black.

Hah. — Sarawak. 



Front of the head and cheeks whitish, vertex and anterior por- 

 tion of the prothorax jet-black, the posterior portion, rather more 

 than half, opake-white or with a slightly ochraceous tinge ; scutel- 

 lum and elytra olive-brown, a narrow stripe along the suture, 

 and another extending from the shoulder to near the apex, pale 

 greyish ; body beneath whitish, with three luteous stripes on 

 the metasternum and abdomen ; femora and bases of the tibiae 

 luteous, the rest and tarsi brownish with a whitish pile ; antennae 

 black. 



Length 7 lines. 



M. Thomson proposes to alter the specific name to Donovani, 

 Donovan having previously described a Saperda under the name 

 of cdllaris. If such a rule were absolute it would be necessary to 

 change the name of every species in the family of which the 

 specific name had been reproduced.
