 the basal half: femora bright yellow, hind pair black on the basal 

 two-thirds except at the extreme base; anterior tibiae yellow with 

 the extreme tips dark brown, the middle pair slightly darker on 

 the basal half, the hind pair with basal half black except the 

 extreme base ; on the apical half the bright golden yellow hair is 

 very thick; tarsi blackish brown. The legs throughout are closely

 Type 9 and cotype & & in my collection ; cotype 9 from Dar-

N.B. — Normally Ptychoptera should have i6-jointed anten- 

 nae, but the 3rd joint in this species is as long as the next two 

 together, and occasionally it appears as if two joints were present, 

 but a careful examination convinces me that it is single. In most 

 of the specimens the whole antennae are certainly present and 

 undamaged. The species, however, cannot possibly be removed 

 from this genus, it being in every character a true Ptychoptera. 



Ptychoptera atritarsis, mihi, sp. nov. 



$ . N. Bengal. Long. 8 mm. (without ovipositor). 



Head. — Whole upper part from the vertex down to the 

 antennae, black, bare, shining ; face below antennae, proboscis, 

 palpi (except black tips) wholly orange-yellow. Antennae black, 

 but microscopically covered with hoary dust ; scapal joints orange- 

 yellow, a few hairs on all the joints. Eyes black, the orbit at the 

 sides brownish yellow, with a set of black hairs, orbit disappear- 

 ing at the vertex. Neck yellow. 



Thorax orange-yellow, piactically bare, dorsum slightly ferru- 

 ginous. A black stripe on the front of the prothorax, which 

 is carried downwards as far as the fore coxae ; two small black 

 spots on the dorsum behind the upper end of this stripe. A black 

 stripe begins widely on each humerus, extending narrowingly 

 backwards to the middle of the metanotum, spreading inwards 

 shghtly at the base of the wings, and narrowly interrupted im- 

 mediately behind their insertion. Under side of thorax shining 

 coal-black, but the sides of the mesothorax are orange- yellow, and 

 a thick scaly process issues from the base of the wings, proceeds 

 widely downwards nearly to the middle coxae, and then bends
