 Plate ix, fig. 7a, Wing of ? ; 7b, Dorsum of thorax ; 7c, Hind tarsus. 



2 . — Wing with the black costa white at the apex and at 

 absolute base, with three yellow interruptions large enough to 

 catch the eye, the innermost of which i^ subdivided by a minute 

 black dot, in addition to which, the generally pale basal fifth of 

 the costa shows three more black dots. Aux. and I. par- 

 ticipate in the formation of these spots, but their light portions 

 are further subdivided by additional black dots. The remaining 

 long veins are yellow, minutely beaded with fairly regularly 

 placed black dots. The internal fringe has fairly distinct 

 yellowish interruptions at all but the last longitudinal junction. 

 All the tarsal joints are apically banded, very indistinctly on the 

 hind legs, but quite prominently so on the two anterior pairs, in 

 addition to which the femora and tibiae are elaborately yellow- 

 speckled. Thorax with two short sub-median brown lines, which 

 with two deep lateral dots and certain other patches give the 

 mesonotum a quaint resemblance to an owl's face. 



Head black, with mixed white and black forked scales and a fairly 

 robust frontal tuft. Antennae clothed with white scales up to the last 

 two joints. Palpi with their apical third white, tinged yellow at the tip, 

 interrupted by two small black bands ; the generally black basal two- 

 thirds with three small white rings. Thoracic decoration due to patches 

 of black and white scales. Halteres entirely white. Abdomen sooty, 

 nude, except for some brown hairs. First hind tarsal joint with three 

 pale patches on its distal half. Length. — 3*5 to 4 mm. 



Habitat. — Taiphing, Straits Settlements (May).
