344 MONOGRAPH OF THE GENUS SYNTHEMIS, 



above, paler beneath, especially around the coxse. Legs of 

 medium thickness, rather short; lengths of femur, tibia, and 

 tarsus respectively are — -foreleg 3-0-1-7 mm.; middle leg 5-4-5-2 

 mm.; hindleg 6-5-5-3 mm.; coxse pale, femora dark brown, some- 

 what hairy, tibiae dark brown, with longer and tiner hairs, tarsi 

 3-jointed, with a few small hairs, ending in two rather small 

 weak hooks. Wing-cases flat, hairy, strongly diverging from 

 bases, so that their tips reach the level of the middle of the sixth 

 abdominal segment, and rest, projecting very slightly from each 

 side of alidomen; fore wing-case placed so completely under that 

 of hindwing that only a small portion along the costa is visible. 

 Abdomen elongate-oval, well rounded above, fairly rounded 

 beneath; broadest at segment 6, tiien tapering rapidly to end, 

 which appears somewhat pointed; no colour-pattern, but the 

 trai.sverse sutures between the segments are rather deeply set 

 under a raised apical ridge of large and conspicuous hairs, giving 

 the body an exceedingly villous appearance, and causing the mud 

 to adhere to it in great quantities: caudal appendages, superior 

 1-6 mm., sharply pointed, curving slightly downwards; two 

 inferior 1 "8 mm, straight, pointed; two smaller laterals, 0-8 ram.; 

 all rather hairy. 



Types: Coll. Tillyard(Leura, Blue Mountains).
