of discoidal cell opposite the middle of the areolet, the

 middle, legs, the 2nd and 3rd segments of abdomen, red ; 

 the latter brown in the middle ; stigma and nervures 

 brown ; base of wing pale. ? . Length, 3*5 mm. 



Var. 1. 3rd segment of abdomen red only at the base ; 

 hind femora brownish to the middle ; apical joint of all

This insect has the antennae of Phygadeuon, but the 

 legs and wings of Hemiteles. I have taken one specimen 

 at Brundall ; Dr. Capron has taken one at Shere ; and 

 another, the var. 1, was taken at Tunbridge Wells early 

 in September, 1881, by Jonkheer J. W. May. 



Hemiteles riijicaudatus, n. s.

Head, thorax, and abdomen smooth and shining, with 

 very fine rather dense pubescence ; head above trans- 

 verse, scarcely slanting behind the eyes ; antennae two- 

 thirds the length of the insect ; 1st joint of flagellum 

 about four times as long as wide, remainder gradually 

 decreasing in length ; apical joints quadrate. Thorax a 

 little longer than high ; mesothorax trilobed in front, 

 lines distinctly impressed ; metathorax short, the upper 

 part shorter than the back part ; areae distinct, supero- 

 medial transverse, postero-medial area defined ; this 

 again divided by a central longitudinal line ; the thorax 

 scarcely wider than the head. Abdomen fusiform ; 1st 

 segment elongate, with scarcely projecting spiracles, 

 gradually tapering from base to apex, which is about 

 twice the width of the base, more than three times as 

 long as the width of the apex; post-petiole with a 

 central groove, this sometimes extending on to the 

 petiole ; 2nd segment nearly as long as the width of the 

 apex, which is the widest part ; remainder transverse ; 

 aculeus one-fourth the length of the abdomen. Legs 

 slender. Wings, exterior nervure of areolet wanting, or 

 almost so ; transverse anal divided one-third from the 

 bottom.
