and legs also distinguislies it from all the genera except Gymno- 

 pJiora, which, however, is of the usual arched PAor«-shape and 

 has the cubital vein forked, costa bare, &c. 



Platyphora LuBBOCKii. Nigra, nitida ; abdomine triangulari, seg- 

 mento tertio parvo ; femoribus posticis basi flavidis ; aUs apice latis, 

 flavido-hyalinis, costa ad basin subciliata, vena cubitali ad medium 

 costEe extensa subcostah parallela, venulis undulatis. Long, f lin. 

 Broad, flat, shining ; frons very broad, the eyes scarcely occupying each 

 one sixth the width of the head ; it is moderately shining, gently arched, 

 and pretty densely clothed with minute bristles ; the three ocelli 

 visible slightly luteous ; antennae with the third joint rather large, 

 somewhat rounded; thorax broad, flat, rather broader than the head, 

 angles tolerably rounded, disk shining (in appearance suggesting a 

 small Spharocera), beset with very minute bristles, which become 

 rather scarcer towards the hinder part : scutellum rather dull, mar- 

 gined, nearly four times as broad as long : abdomen black, narrower 

 and shorter than the thorax (again suggestive of Sphcsrocera) ; each 

 segment after the second successively narrower, the last one being 

 almost triangular ; the third segment is very short, contracted under 

 the second; the hind margins form a curve convex towards the thorax, 

 the first segment being slightly emarginate in the middle ; the sixth 

 (last) is much the longest. Legs stoutish, blackish, basal two thirds 

 of hind femora yellowish; middle tibiae with two small spines at the 

 tip. Wings considerably overlapping the abdomen, yellowish hya- 

 line, dai-ker about the basal half of the costa, blunt at the tip, cubital 

 vein extending about half the length of the wing, and the costa slightly 

 ciliate up to its end, subcostal vein running parallel to it and ending 

 just before it ; both veins a little thickened at their ends ; first veinlet 

 curved S-like, considerably at its base, slightly at its end, vanishing 

 distinctly before the tip of the wing ; second veinlet also S-like, di- 

 verging at its end from the first, and ending distinctly below the -tip 

 of the wing ; third veinlet slightly undulated, ending very wide from 

 the second; fourth faint, not reaching the end of the wing. 

 This description having been made from a specimen gummed 

 down on card, though in very good condition, I am unable to 

 decide on the sex, or to examine the face, palpi, base of antennae, 

 or coxgB.
