outer faces strongly excavated. Spurs minute, bristle-like. 
Tarsi robust; first, second, and third segment sub-globose, 
slightly dilated on inner side; fourth segment more cylin- 
drical, a little longer than any of others; each of four basal 
segments with an internal tuft of bristles; fifth tarsal 
segment thinner than others, cylindrical, narrower at apex, 
a little longer than third plus fourth. Claws similar to 
those of forelegs. 
Hind legs: Coxae (fig. 10) long, transversely placed. 
Trochanters more triangular than middle ones, with some 
bristles. Femora much longer than middle ones ; under 
surface smooth ; one keel on anterior margin ; posterior 
face excavated. Tibiae much shorter than femora, less 
dilated towards apex than middle tibiae but more strongly 
arched. Spurs bristle-like. Tarsi similar to those of fore — 
and middle legs. 
The present species can be distinguished from Harold- 
ius globosus by the following table: 
11 . philippinensis n. sp. 
Larger (3.5-4.0 mm.) 
Black with brownish overtones on 
front of clypeiis, elytra, under parts, 
and legs 
Elytia pubescent, with striae visible 
on anterior half and effaced pos- 
teriorly 
//. globosus Boucomont 1925 
Smaller (2.0 mm.) 
Metallic green with a slighi 
purplish sheen 
Elytra glabrous, with striae ef- 
faced on disc 
Type-locality: Dingalan Bay, East Luzon, Philippine 
Islands. 
Type-material: Type and 3 paratypes in the Museum 
of (^Comparative Zoology at Harvard College; 2 paratypes 
(one dissected and mounted on slides) in the Departamento 
de Zoologia, Sao Paulo. All collected by P. J. Darlington 
(VII-VIII, 1945) at the type-locality, in a nest of ants of 
the genus Diacamma (group vagans F. Smith, Ponerini). 
This genus is scarce in collections. The biology of the 
species is poorly known. Some of them have been found in 
ant nests {H. heimi with Pheidole latinoda, the present 
species with Diacamma ) . H. perroti has been collected with 
numerous specimens of Bacanius (Coleop., Histeridae) by 
sifting dead leaves.
