The lac was obtained by Mr. R. S. Troup from Bisbanpur in the 
Saharanpur District, and a number of trees of Butea frondosa were in¬ 
fected with it. The experiments were carried out at Ranipur in the 
Siwalik Forest Division. Samples of the lac were sent from time to 
time by Mr. Troup to the Forest Zoologist at Dehra Dun who reared the 
parasites described in this paper. 
CHALCID1D/E. 
Chalcidinse. 
Centrochalcis , gen. nov. 
Antennae, 11-jointed, placed opposite the end of the eyes, slender, of 
uniform thickness, the scape narrow, reaching to the ocelli. Eyes bare ; 
the malar space not quite so long as them. Apex of scutellum rounded. 
Metanotum with the sides broadly rounded, without projections—abdomen 
sessile, the basal segment as long as the following 3 united—about one- 
third shorter than the others united; the ovipositor broad, nearly as long 
as the abdomen. Hind femora with about 10 short, blunt, clearly sepa¬ 
rated teeth, which are almost hidden by the dense hair. Apical nervures 
thick; the stigmal curved, as long as the post-stigma, which is gradually 
narrowed towards the apex. The abdomen in the ? ends in a stout, 
broad stylus, which almost, or quite, equals it in length. Head, thorax 
and legs and the apices of the abdominal segments densely covered with 
silvery pubescence. There is only one ring joint in the antennae; it is 
bare; the flagellar joints are elongate. Malar space half the length of 
the eyes. Base of abdomen rounded. 
The antennae are not placed quite so high up on the face as in some 
species of the group, but the genus can hardly be placed in the Haiti - 
chellini. In the arrangement of Ashmead [Mem. Cairn. Mus ., i, 248) 
it would run near to Trigonura and Thaumatella , both neotropical genera, 
with which it cannot be confounded. 
Centrochalcis rnjicandis , sp. nov. 
Black, densely covered with longish glistening white pubescence, the 
ablominal segments fringed with longish white hair; a band on the apex
