Thorax olive, clothed thickly with fine white hairs, which are 

 longer at the anterior edge of the dorsum. Dorsal carina yellow, with 

 a broad brown stripe on each -side covering half the distance to the 

 humeral suture ; this stripe is somewhat obscure, though distinct, and 

 sends off a narrow acute process at its upper end to the humeral 

 suture. Sides of thorax olive, an elongated yellow spot on the lower 

 half of the first lateral suture, a triangular spot above below the fore 

 wings and a quadrangular spot at the front edge of the hind wings, 

 both yellow. Above with yellow spots at the bases of all wings. Legs 

 olive, the carinas yellow, these markings, however, not very distinct. 

 Spines of the legs and tips of the tarsal claws brown. 



Abdomen : segments one and two and basal half of three olive, 

 two with a latero-inferior basal yellow spot, three with a very narrow 

 yellow nasal ring. The remaining segments are obscure brown, though 

 there are indications of lateral yellow oblong spots on segments three 

 to nine. Appendages as long as nine plus ten, yellow at the basal 

 third, then obscure brown. Vulvar lamina very short, hardly one- 

 tenth the length of nine, rectangularly excised, lateral lobes broadly 

 rounded. 



Wings hyaline, the venation brown, yellow near the costa. At 

 the extreme base the wings are blackish in the costal, subcostal and 

 median space. Four basal subcostal antecubitals with a small brown 

 spot surrounding each, the spots not larger than one-sixth of the 

 space between the cross-veins; fifth and sixth antecubitals (subcostal) 

 very narrowly margined with brown. Nodal spot very small, consist- 

 ing of a narrow internal subcostal streak and a similar narrow post- 

 nodal streak. Hind wings similarly marked, with the spots one-third 

 larger. Stigma of all wings brown, membranules white, black at the 

 spical third. Venation :
