 minute, appressed, black hairs ; antenna ochraceous or 

 tawny, tip of third joint (last four annuli) clove-brown or 

 black, first two joints clothed with minute black hairs, 

 upper angle of second joint much produced, third joint 

 1*8 mm. in length, its upper branch 1 mm. in length, very 

 slender at its distal extremity, which is curved downwards. 

 Thorax : extreme front margin of dorsum showing vestiges 

 of two paler, elongate, admedian flecks, dorsum clothed with 

 brownish, pleurae with buff-yellow or maize-yellow hair. 

 Abdomen : black longitudinal stripes on dorsum commencing 

 on first segment, and, if extending to distal extremity, some- 

 times more or less confluent on fifth and sixth segments ; in 

 other specimens stripes are interrupted on front half of 

 fourth segment, commencing again more or less indistiuctly 

 towards hind margin of same, and thence being continued to 

 tip of abdomen, although by no means so sharply defined as 

 on first three segments ; inner margins of stripes more or 

 less excavated on each segment after first and consequently 

 irregular; though widely separated from lateral margins on 

 first two segments, stripes are more or less connected there-

 clothed with minute orange-buff hairs, more or less inter- 

 mixed with minute black hairs, with which alone the black

 sharply on posterior branch of third longitudinal vein, and 

 so wide as to occupy distal three-fourths of second sub- 

 marginal cell; distal margin of transverse band commencing 

 on (occasionally just above) second longitudinal vein, at a 

 point about two-thirds of distance between distal extremity 

 of stigma and apical blotch ; proximal margin of transverse 

 band commencing a little beyond level of proximal end of 

 stigma, indented in discal cell, and again, and more deeply, 

 in fifth posterior cell ; first basal cell with a minute, elongate, 

 hyaline streak or spot in extreme base, next upper margin ; 

 fourth longitudinal vein passing through an elongate, hyaline 

 streak just before meeting anterior basal transverse vein.
