Szépligeti from Java, is certainly misplaced. It properly be- 
longs in the genus Syrites Tosquinet, where it is very closely 
related to the Philippine (Astomaspis) Syrites metathoracica 
(Ashmead). None of the other four species is available for 
study, but the two new species, one from Singapore and one 
from the Philippine Islands, described below, are apparently 
distinct from either, as indicated by the following key which 
includes all six species: 
Key to the Oriental and the Australian species of Hemigaster.

Hemigaster malayensis sp, Nov. 
Female.—Length, 9 millimeters ; antenne, 8.5; front wing, 7.5. 
Vertex laterally with large, rather sparse punctures, which 
merge anteriorly into the irregular rugosity of the sides of 
frons; interocellar space opaque, without distinct sculpture; 
margined only at sides, the carinee merging into the general 
sculpture above; median horn thick and canaliculate on dorsal 
edge, bilobed at apex; face and clypeus reticulate-rugose, more 
coarsely so at sides, elevated in middle; clypeus without a me- 
dian apical tooth; cheek and lower temple transversely rugose, 
this fading out to fine, rather dense punctuation at the middle 
of the eye. Pronotum rather finely punctate above, coarsely 
foveolate in ventral angle and along anterior and posterior mar- 
gins; mesoscutum rather finely, very densely punctate, notauli 
distinct to middle, prescutum with a median groove anteriorly; 
scutellum sculptured like the mesoscutum, tapering to the very 
narrow apex, and with strong lateral carinz extending to the 
apex ; mesopleurum densely rugulose with an oblique, transversely 
striate area in the middle; anterior and posterior furrows fo- 
veolate ; prepectal carina approaching anterior margin gradually ;
