Length nearly lYi mm. 



Most nearly related to A . inacrophadna ; but it is smaller^ 

 the colour of the legs is yellow, not reddish or reddish- 

 testaceous ; the wings are shorter, the radial cellule is 

 shorter and narrower. In the $ the curvature in joints 

 4 and 5 is better marked, and the third joint is longer. 



It is a larger species than A. bnsimacula ; the antennae 

 are of a paler and clearer yellow, not dark fuscous, and much 

 stouter and with the fourth and fifth joints thicker and 

 more curved ; the legs are clear yellow, not reddish tes- 

 taceous ; the abdomen is longer compared to the thorax 

 and the radial cellule is wider.

Allotria perplexa sp. nov. 



Black ; joints i — 5 of the antennae and legs testaceous, 

 the femora broadly black or infuscated in the middle ; 

 wings hyaline, the nervures pale fuscous. Antennae as 

 long as the body, distinctly thickened towards the apex ; 

 the third joint one-fourth longer than the fourth ; the 

 last one-half longer than the penultimate. Radial cellule 

 moderate in length, broad ; the first abscissa of radius half 

 the length of the second, which is a little more than twice 

 the length of the third, the third slightly curved. The hair 

 on base of abdomen and metathorax very dense. The $ 

 has the antennae filiform, longer than the body, the third 

 joint longer than the body, curved. 



Length \y^ mm. 



There are two species described which have the femora 

 darkened and with the tibiae and tarsi testaceous as in 

 perplexa and crassa, namely A. aperta, Htg., and A. fuscipesy 

 Thomson ; but both differ from perplexa and crassa in having- 

 the antennae shorter ; fiiscipes having them scarcely longer,, 

 and aperta almost shorter than the thorax.
