T. D. A. COCKERELL. 205 



marginal cell narrowly obliquely truncate ; second s. m. broad, receiv- 

 ing first r. n. a little before middle; second r. n. joining third s. m. 

 near end ; legs dark rufopiceous ; scopa of hind tibiae fuscous seen 

 from above, but beneath with very long curled white hair, strongly 

 plumose at ends ; abdomen broad, with varied bluish and green tints, 

 very little punctured, the second segment nearly impunctate except 

 for a row of scattered punctures just before the marginal area ; no 

 hair-bands ; apex with dark fuscous hair ; ventral segments fringed 

 with long glittering white hair, only a little stained with fuscous on 

 the fifth ; apical plate rounded, not keeled ; hind spur with five long 

 spine-like teeth. 



Closely related to P. carinattis Smith, but larger, with the 

 clypeus black and the fringe on fourth ventral segment white.

Paracolletes melbournensis sp. nov. 



9 . Length about 11 mm. ; olive-green, the clypeus and supra - 

 clypeal area strongly punctured, black, with crimson and golden tints 

 at sides and in the vicinity of the suture between them ; flagellum 

 ferruginous beneath only at apex ; hair of head and thorax ferruginous 

 above, white below, but dark fuscous on vertex, middle of scutellum, 

 and intermixed on disc of mesothorax ; face very broad ; mesothorax 

 dullish, well punctured, a purplish-black nearly impunctate discal 

 patch ; area of metathorax transversely grooved, and with an evident 

 though variable transverse keel ; tegulae shining piceous ; wing hyaline, 

 nervures and stigma rather dark reddish; b. n. meeting t. m. ; first 

 r. n. joining second s. m. in middle; second r. n. joining third s. m. 

 almost at apex ; legs black (not at all red); scopa of hind tibiae black 

 on upper outer side, otherwise white; hind basitarsus broadened ; hind 

 spur with long spines ; abdomen entirely olive-green, with a dullish 

 sericeous surface ; apical fimbria black ; ventral segments 2 to 4 with 

 pure white fringes, fifth with a yellowish fringe. 



Superficially just like P. cupreus semipurpureus , var. a, but 

 considerably larger. From cupreus proper it is known by 

 the black legs and pure green abdomen. It is also related 

 to P. amabilis, but larger, and with the legs differently 

 colored. All these insects form a group of closely related 

 forms, and with the material at present available it is uncer- 

 tain how many valid species are represented. 



Hab. — Melbourne, Victoria (Rolle; Berlin Museum). 

 Another specimen, in poor condition, is from Victoria (C. F. ; 

 Turner collection). British Museum.
