Plate 70, figs. 5, 6. 



Described from a type male collected at Woking, Surrey, England, 

 April 24, 1900, by G. C. Champion, and two paratype males col- 

 lected April 5, 1912, and April 23, 1912, at Woking by H. G. Cham- 

 pion. 



Length 3.5 mm. Velvety black, with appendages and wing veins 

 piceous black, tarsal pads creamy yellow, ninth abdominal segment 

 and oedeagus, yellowish, tenth segment black. Wings milky. 



Eyes stalked with many ommatidia, very narrowly separated. 

 Head triangularly produced. Antennae six-jointed; first joint 

 longer and broader than second, which is ring like ; third, ring like 

 with long, broad, flattened flabellum, reaching about to middle of 

 sixth; fourth, broad, flattened, as long as the next two together, 

 which are subequal. Mandibles small, transparent yellowish, acute, 

 ensiform, barely as long as the first joint of the maxillae. Maxillae 

 two-jointed, the first longer than the second, broad, flabellate, longi- 

 tudinally curved, with the depression beneath ; first joint longer than 

 second, the two equalling the third and fourth antennal joints. Head 

 with small circular emargination behind. 



Prothorax and mesothorax simple. Metathorax with keystone 

 shaped praescutum, scutum two-lobed, separated by scutellum, which 

 is narrowly pedunculate in front. Scuti carinate from wings almost 

 to scutellum, thus indicating partial separation of parascutellum. 

 Postlumbium black subchitinous, bisinuate at base, elongate rounded 

 behind, as broad as long. Postscutellum longer than anterior por- 

 tions of metathorax. Concave for reception of abdomen. 



Wing venation consists of the basal costa, strong marginal sub- 

 costa; the approximate radius with the area between darkened, a 

 short detached vein arising near the apex of radius ; the usual medius 

 with a faint detached vein in front of it and a short approximate 

 detached vein behind it near apex; cubitus and three anal, the last 

 rather short. A strong fold occurs between medius and cubitus. 



The hypoepimeron (femoralium) practically incloses the posterior 

 coxae. 



The color of the anal regions is unusual.
