NEW AND LITTLE KNOWN INDIAN BOMBYLIIDAi. 
By Lieut.-Colonel C. G. Nurse. 
{Continued from page 641 of this volume.) 
Part II. 
When I began my studies of this family, I hoped to deal with the Lidian repre- 
sentatives of all the genera as fully as I have dealt with those belonging to the two 
genera, Litorrhynchus and Exoprosopa, included in my former paper. But un- 
foreseen circumstances have necessitated my removal from London, and I have 
no longer the opportunity of consulting the library at the British Museum, or of 
access to the specimens in the national collection. In the present paper, 
therefore, I confine myself to material I had prepared before leaving London, 
but as it brings forward representatives of several genera not previously 
recorded from Indian limits, it may probably be useful to dipterists studying 
the fauiia of Lidia. 
Some changes of nomenc ature are unfortunately necessary, as Pro- 
fessor Bezzi has pointed out that the genus hitherto known as Argyramotha 
should be known as Anthrax, while he has, very properly I consider, 
split up the old genus Anthrax. Such changes are very puzzling to students 
of insects who do not happen to be specialists, but as Professor Bezzi 
has been followed by Becker in his “ Genera Bombyliidarum,” which is 
perhaps the most up-to-date study of the family as a whole, I have conse- 
quently followed them in this paper. 
The genus Exprosopa has, as I anticipated when dealing with its Indian repre- 
sentatives, now been split up by Professor Bezzi (Ann. S. African Museum, Vol. 
XVIII, p. 138) into several new genera. 
Anthrax Scop. {Argyramoeba, olim). 
Before dealing with the Indian representatives of this genus, I should state 
that m 1908 Professor Bezzi erected a genus Petrorossia for the species which 
had, up to that time, been known as Argyramoeba hesperus, Rossi. He has since 
described in Trans. Ent. Soc., 1911, pp. 615-17, several new species of Peb'orossta 
from Africa. As representatives of this genus occur in India, it will be necessary 
to differentiate Petrorossia (which Becker places in a different sub-family) from 
Anthrax. The two genera may be tabulated as follows : — 
Prtefurca long ; 2nd longitudinal vein arising from the 3rd 
opposite or nearly opposite the anterior cross-vein . . Anthrax. 
Preefurca short ; 2nd longitudinal vem issuing from the 
3rd further from the anterior cross-vein than the length 
of the cross-vein itself . . . . . . . . . , Petrorossia. 
Anthrax indicata, n. sp. 
Head ; frons at vertex less than -J- the breadth of head, at level of antennae 
about f ; frons and face blackish brown, covered with short stiff black hairs, mix- 
ed with a few grey ones near upper mouth edge ; a little white tomentum near 
eye margins ; antennae dull black, 3rd joint onion-shaped, its base with a little 
grey shimmer, style bisected at about f its length, its apex with the usual pencil 
of hairs ; proboscis short, blackish brown ; occiput dull black, deeply indented 
at vertex, with a little white tomentum along eye margins ; occipital fringe dark 
brown. Thorax black, covered above with black hairs, mixed with some greyer 
ones especially about the pronotal collar ; on the disc, especially about the 
wing bases, there are some very fine short yellowish grey scales ; below the pube- 
scence is rather long, entirely grey ; scutellum concolorus with thorax, and 
similarly clothed ; the marginal hairs, which are too fine to be called bristles, 
long and black.
