A NEW MALAYAN ANT OF THE GENUS 
PRODISCOTHYREA. 
By Witi1am Morton WHEELER, 
Bussey Institution, Harvard University. 
Prodiscothyrea bryanti sp. nov. 
Worker: Length, 2 mm. Very similar to the genotype P. vel- 
utina, which I recently described from Queensland, Australia 
(Trans. Royal Soc. South Australia, 40, 1916, pp. 33-37, Pl. 4), 
but differing in the following characters: The head is proportion- 
ally smaller and much less convex above, especially behind the 
frontal carine, the eyes are much smaller and the cheeks have a 
more prominent blunt tooth in front of the eyes. The antennal 
scapes are less abruptly narrowed at the base and the funicular 
joints, with the exception of the last are even more transverse, so 
that the whole funiculus is shorter, being scarcely longer than the 
scape. Thorax shorter, not 15 times as long as broad, less convex 
in front, with less angular humeri and with more distinct epinotal 
teeth and more nearly vertical epinotal declivity. Petiole much 
smaller and broader, nearly four times as broad as long and with a 
more pronounced, compressed, translucent tooth on its ventral sur- 
face. Postpetiole alsoshorter, less decidedly narrowed in front and 
less depressed above in front than in velutina. Sculpture, pubes- 
cence and color very similar to those of velutina but the dark median 
dorsal line on the postpetiole and first gastric segment is lacking.

Straits Settlements by Mr. G. E. Bryant and sent me by Mr.
