by egg parasites and lack of food. The work of Perkins in Hawaii has 
shown that one species at least is attacked by a variety of parasites and 
one of the Indian species is also the host of several parasites. (See 
Dryinidce, page 170.) These parasites presumably check the increase 
of these insects and some Fossorial wasps store their nests with 
Fulgorids, which is another check upon their increase. 
The classification of Fulgoridce cannot yet be said to have arrived 
near to definiteness from the extremely little really known of this 
large family. Distant, following 
Stai, makes twelve sub-families, 
the key to which is in the volume 
of the Fauna. We are not in a 
position to enter into this here, 
so small a portion of our plains 
species having been worked out 
and the student of this family 
should consult the original 
volume which we follow. We may Fig. 498 -Pyrops chennelli. x l|. 
remark that we hope that a revi¬ 
sion of the family, and its division into more natural groups will follow 
from increased knowledge of tropical forms, little known as yet. It is 
unfortunate that only the smaller and less known species occur in the 
plains and that these have been so little studied. The giants of the family 
are wholly hill insects and must be omitted here. Records are extremely 
scanty in this family so far as plains species are concerned and of the 330 
species mentioned by Distant, barely a dozen are mentioned by him as 
common in the plains or as occurring in localities at low elevations. This 
is due, not to the small number of plains species, so much as to the fact 
that collectors have gone to the hills and no collections have been made 
in the plains. We are dependent upon the Pusa collections in this case 
and the species mentioned are those we have found. 
Fulgorince .—Anal area of wings reticulate, ridge separating frons 
and gena continued on to clypeus. This sub-family includes the large, 
beautifully coloured hill forms in which the prolongation of the head 
takes such curious forms. (Fig. 498.) Unfortunately only one (Pyrops 
chennelli) appears to be a common plains form and the recorded species 
are wholly forest and jungle hill species.
