of scutcllum ; liind margin of latter olive- grey, olive-brown 

 area on disk sometimes divided; pectus and pjeune drab- 

 grey. Abdumen clothed for the most part with minute 

 oehraceous hairs, darker parts of dorsum with brownish 

 hair; venter yellowish grey, unieolorous. Wings brownish, 

 pale markings clearly defined throughout, from base of bas;il 

 cells to end of fork of third longitudinal vein, but coarse and 

 much broken up, especially in apical portion ; siiyma russet 

 or piile oehraceous, elongate, and well defined ; pale loop at 

 distal end of stigma rather narrow; first submarginal cell 

 crossed by pale marks at subequal intervals, and sometimes 

 with a relatively rather large pale blotch at its distal extre- 

 mity, in angle formed by up})er branch of third vein with 

 costa ; second submarginal cell crossed by three pale streaks, 

 and in addition usually with a pale mark immediately below 

 tip of upper branch of third vein ; posterior cells with a 

 distal series of oblique detached pale marks, running at an 

 angle of about 45° to hind margin, and sometimes also with 

 a series of pale marks along hind margin itself, in the proximal 

 angles formed by the veins ; rosettes round distal extremities 

 of diseal and basal cells more oi less distinct; discal cell 

 with two pale marks across central portion and usually a 

 third pale mark in distal extremity ; markings in basal, anal, 

 and axillary cells normal, an almost complete loop at base of 

 axillary cell, in angle formed by sixth longitudinal vein. 

 HaUtrts light mummy-brown, stalk cream-coloure;!. Leys: 

 nnddle and hind tarsi brown, except basal three-fourths of 

 first joints, front tarsi as usual darker.

In the abdominal markings, at any rate. Hamatopota 

 brcvicurnis, like H. pallidipenuis, presents a certain resem- 

 blance to H. bruniiescens, Kicardo, alluded to above ; but, 

 apart from its usually smaller size, it may be distinguished, 

 iitlir alia, by the shortness of the terminal aunuli of the 

 third autennal joint and by tliL; coarseness of the pale 

 markings of the wings.
