NEW AND LITTLE KNOWN INDIAN BOMBYLIIDE. 
887 
rather long black bristles and a few grey scales ; halteres brownish, pale yellow 
at tip. 
9 Similar ; vertex and abdomen much broader ; the abdominal bands of 
greyish white scales rather broader than in the d . 
L. 18 mm. 
Described from 2 d d and 1 9 in good condition obtained at Quetta in April 
and May. 
CallistoDM may be recognised from other Anthracince by the long proboscis, 
narrow abdomen, and radial vein diverging from the praefurca well before the 
discal cross-vein. The 1st posterior cell is closed and long stalked. The present 
species is much larger than any previously described in this genus, none of which 
exceed about 12mm. in length. The 4th posterior cell is twice as wide at base 
as at apex, whereas in C. fascipennis it is only 1^ times as wide. The 1st post- 
erior cell is closed nearer to the wing margin in my two ^ ^ than in the 9 > but 
this may be only an individual variation. 
The larva of the European species (C. /ascipew?u’s) is reported (Tr. Ent. Soc., 
1881, XIV) to be parasitic on the egg cases of locusts. The genus appears to 
be confined to Eastern Europe and Western Asia. 
Mariobezzia griseohirta, n. sp. 
d Head ; eyes separated at vertex by about f the breadth of head, frons and 
face gradually widening towards mouth edge ; vertex narrowly black, the colour 
extending over the occiput ; frons and face whitish, the raised portion between 
the base of antennae and mouth edge reddish brown, with a darker line down the 
middle ; antennae black, 3rd joint three or four times as long as the first two 
together, style very short ; the facets on the lower third of the eyes are much 
smaller than those on the upper two-thirds ; the cheeks from the lower portion 
of eyes to the mouth edge, and the proboscis dark brown ; face, frons, and occi- 
put covered with greyish pubescence. 
Thorax and scutellum entirely black, with rather long grey pubescence. Ab- 
domen black, the apical margins of segment 1 — -3 with narrow white transverse 
bands, 4th segment at apex narrowly testaceous ; venter black, with apical mar- 
gins of first foTir segments more or less pale ; the whole abdomen covered with 
grey pubescence. 
Legs ; coxae and femora, except the extreme apex of the latter, black with 
grey pubescence ; tibiae pale at base, darkening towards apex ; tarsi dark brown. 
Wings hyaline, with a suffused patch or band from anterior margin towards 
discal cell, blackish on margin, becoming gradually less dark, and hardly notice 
able beyond discal cell ; nervures pale, tegulae dark, halteres creamy white. 
L. 6 mm. 
Described from one specimen obtained at Quetta in May. 
This species is much darker and more pubescent than either lichlwasdti. 
Beck or zarudnyi Beck, both of which are bare, and have the thorax mainly 
yellow. As regards neuration and the shape of the face it exactly agrees 
with Becker’s description of the genus in Genera .Bombyliidarum, p. 470. 
Heterotropus itidicus, n. sp. 
^Head ; pale green, eyes touching for a space rather shorter than the vertical 
triangle, which is distinctly raised, and on which there are a few pale hairs ; 
antennae with the first joint pale green, the 2nd similar but rather darker above, 
3rd joint pale yellow, the latter, excluding style,nearly twice as long as the other, 
two taken together ; style pale red, about as long as 3rd antennal joint ; 
proboscis and palpi yellow, the former dark brown at apex ; eyes with the lower 
third divided from the upper portion by a fine line, the facets on the lower part 
very fine ; above this line the facets are much larger about the middle of the 
eyes, decreasing in size on the upper third ; occiput with fine soft pubescence.
