liind tarsal segment not a (luaitcr as lonj^ as the tibia and 

 scai'cclv as lon*;^ as tlio two following .sognients togetlicr. 

 The tibiie show no trace ol' apical spurs. The articulations 

 (jf tlie tarsal segments are oblique, and there is a ratlier 

 extensive membrane between most of the segments. The 

 fifth tarsal segment on all the legs is somewhat enlarged 

 apically, and bears a very Jarge, nearly circular, liairy 

 enipodium. There is a single rather long and slender, 

 simple, straight, and pointed claw, the second claw being 

 apparently represented by a minute blunt prominence*. 



JVinf/s extremely large for the size of the insect, very 

 broad, with a conspicuous anal lobe. There are no macro- 

 trichia on any part of the surface, not even on the costal 

 margin, bnt there is a rather long and delicate fringe round 

 the anal lobe, and the whole membrane is covered with short 

 microtrichia. The costal margin is only slightly thickened, 

 and not any darker than the rest of the wing. There are 

 also very slight thickenings of the membrane faintly indi- 

 cating some of the veins, the most distinct being Sc and jRi, the 

 former of these apparently terminating in the latter at about 

 the middle of the length of the wing. More distinct than 

 tliese vestiges of the true veins is the "secondary venation.'^ 

 This is quite obvious when the wing is in formalin, and on 

 a wing being removed and mounted dry it became so con- 

 spicuous as to appear like a true venation. Were it actually 

 so, the insect could hardly be included among the Diptera f. 

 Close examination, h(jwever, shows that practically all the 

 lines are produced merely by creases in the wing, there being 

 very little trace of true veins. When a wing is mounted in 

 balsam, the '' secondary venation " abnost entirely disappears 

 and the traces of true veins referred to above become more 

 apparent. The two photographs given will indicate the 

 arrangement of the vein-vestiges and of the secondary folds. 

 The latter are arranged in a fan-like manner, somewhat 

 suggestive of the hind wing of an earwig. Besides the 

 radiating folds there are three concentric lines across the 

 field of the wing, Ijesides two short transverse lines in the 



* It is just possible that the organ regarded as an empodium represents 

 tlio secoud claw. Compare tlie JJlepharocerid genus Hupalothnx, in 

 ■which both claws are large and piilvilliforiu. 



t The only insects which have a venation even faintly resembling this 

 are Maytiies of the genus Ccenis and allied forms, which also, like our 

 insect, have no mouth-parts or hind wings and even a somewhat 

 similarly shaped head. A cursory examination, however, soon shows 

 that these are the only resemblances between the two groups — the Mav- 

 iWv^, for eifimple, having very differently constructed thorax and legs and 

 no halteres.
