IBS 



especially on the upper side ; ta.Si with tiny black bristles, but with 

 orange ones on the soles of the posterior pairs. Pulvilli yellowish 

 brown ; claws blackish. 



Abdomen longer than the head and thorax (including the 

 scutellum) together, somewhat parallel-sided but gradually narrowed 

 towards the rounded apex. Dorsum brownish orange with a more or 

 less broad (about one-third the width of the abdomen) blackish dorsal 

 stripe, and with the tip blackish, but with all the actual sidemargins 

 orange ; this dorsal strip begins on the whole breadth of the basal 

 segment and contracts to about the middle third (or fourth) of the 

 hindmargin of that segment, and then gradually widens to the end of 

 the third segment, the fourth and subsequent segments being almost 

 entirely blackish, though the orange hue may extend somewhat down 

 the sides of the dorsal stripe on the fourth segment, and the blackish 

 sides of the fourth segment may extend faintly upwards near the sides 

 of the third segment, and there may be a small round isolated blackish 

 spot near each side of the second segment right in the middle of the 

 orange part. Pubescence all over composed of moderately dense 

 depressed glistening deep orange yellow hairs, amongst which abundant 

 though inconspicuous more bristly black hairs occur, which are some- 

 times somewhat conspicuous on the lateral margins of the broad 

 dorsal stripe so that there are two narrow blackish dorsal stripes, and 

 which are longer and when viewed sideways conspicuous and erect on 

 the basal part of the middle part of the disc of the second segment and very 

 few (or sometimes wanting) on the basal segment, and also which almost 

 always disappear about the brownish orange basal markings except on 

 the isolated blackish spot on the second segment and about the middle 

 of the orange part of the basal segment ; side marginal pubescence all 

 orange except for a slight blackish tuft at each side of the basal 

 segment ; the dense orange pubescence and dust sometimes obscure 

 the black dorsal stripe and tip. Ventre greyish black but thickly 

 covered with a brownish yellow tomentum and with the hindmargins
