436 MAJOR E. E. AUSTEN, 



Head : Subcallus drab, front, face and jowls greyish-olive pollinose, face and 

 jowls clothed with line dark-brown or blackish-brown hair, occiput pale smoke-grey 

 pollinose, clothed with fine hair of similar colour, occipital margins fringed posteriorly 

 with short, glistening yellowish hair, except behind vertex, where the somewhat 

 longer hairs are blackish ; front in $ narrow, somewhat wider above than below, 

 clothed with minute, appressed, glistening yellowish hairs, vertex also bearing short 

 blackish hairs, in typical specimen with a median, dark, somewhat shining, elongate 

 mark, but showing no trace of an ocellar tubercle; frontal callus, blackish-brown, 

 longitudinally elliptical in outhne, and continuous above with a median rib-like 

 extension of same colour, which, in case of typical specimen, reaches a point well 

 above midway between lower end of front and hind margin of vertex ; eyes bare, 

 without recognisable bands in dried condition ; palpi, drab, proximal segment clothed 

 with fine dark brown or blackish-brown hair, distal segment in $ elongate, bluntly 

 pointed at distal extremity, and clothed on outer surface with minute, appressed, 

 black hairs, among which, especially at base above, a number of minute, glistening 

 yellowish hairs is visible ; first and second segments of antennae cinnamon-buff 

 (pinkish-buff when viewed from above), clothed with minute black hairs, first segment 

 partly embracing second, its upper distal angle being prominent, upper distal angle 

 of second segment considerably produced, third segment cinnamon (infuscated at 

 extreme tip in case of type), fairh^ deep at base, with a prominent though not elongate 

 angle on upper border, after which expanded portion is somewhat elongate, the part 

 of expanded portion beyond the angle being about twice the length of the part from 

 base to angle inclusive, total length of annulate portion of third segment about half 

 that of expanded portion. Thorax : Dorsum (except anterior border, humeral calli, 

 and scutellum, with exception of its black base) clothed with black hair, which is 

 thus present on base of scutellum also ; humeral calli clothed with gi-eyish- white 

 hair, upper portion of anterior border of dorsum sparsely clothed with minute 

 appressed, glistening yellowish hairs, a few similar hairs also present among the 

 adjacent black hair ; pleurae clothed partly with black, partly with brownish hair ; 

 anterior surface of thorax, next to occiput, olive-grey pollinose ; pleurae and pectus 

 dark brownish olive-grey pollinose, a thin coating of similar character and colour 

 also present on dorsum of scutum, at least anteriorly, although, at any rate in a 

 partially rubbed specimen, dorsum appears somewhat shining. Abdomen : Dorsum 

 somewhat shining ; whitish hairs forming lateral patches on dorsum fine and some- 

 what thinly set, lateral patches on first (visible) segment confined to the actual 

 posterior angles, on following segments corresponding patches are much larger, each 

 patch occupying on lateral margin at least posterior half of the segment, diminishing 

 in depth towards middle line while remaining in contact with hind margin of tergite, 

 and extending over about one-fourth (on fifth tergite about one-third) of the width 

 of the segment ; sixth tergite with a few scattered whitish hairs near each lateral 

 extremity ; dorsum, except as stated, clothed with short, appressed black hair ; 

 venter brownish-black, moderately shining, clothed with short, appressed black hair, 

 among which on hind borders of second and two following sternites, and also scat- 

 tered over surface of fourth sternite, are short or minute, glistening whitish hairs. 

 Wings : Veins mainly dark brown, second longitudinal vein partly, third longitudinal 

 at base, and anterior transverse vein tawny-olive ; anterior branch of third vein 

 (at least in type) with a small appendix (in case of type, more noticeable in right wing 

 than in left) ; stigma, tawny-olive, elongate and inconspicvious ; first basal cell faintly 

 tinged with sepia ; mummy-brown transverse band wider on costa than towards 

 hind margin, and dying away before reaching latter, but extending into fourth 

 posterior cell ; on costa, band extends from a point about half-way along lower 

 margin of stigma to end of first submarginal cell ; thence, distal margin of band 

 runs obliquely backwards, showing a more or less pronounced indentation in second 

 submarginal cell ; proximal margin of band straighter, running across wing practi- 

 cally at right angles to longitudinal axis of latter, and including distal extremity
