200 HYMENOPTERA. 



very large punctures, and an imperfect smooth median band ; sides of 

 front dull and rugose ; face on each side of clypeus covered with ap- 

 pressed white hair ; flagellum obscurely brownish ; fourth and fifth 

 antennal joints very short, broader than long ; mesothorax and scu- 

 tellum densely punctured ; postscutellum with a stout median spine or 

 tooth, which emits a few long curled black hairs ; pleura with large 

 irregularly placed punctures ; area of metathorax triangular, dullish, 

 its upper part transversely striate ; hair of thorax mostly white, black 

 on scutellum and disc of mesothorax, also black just beneath wings ; 

 tubercles densely fringed with white hair, making them appear as 

 white spots ; tegulse shining piceous ; wings dusky, especially dark in 

 upper part of marginal cell and on apical margin ; b. n. meeting t. m. , 

 the latter oblique; first s. m. very long; second small, receiving first 

 r. n. at its basal corner; second r. n. received about beginning of last 

 third of third s. m. ; legs reddish-black, obscurely submetallic, the 

 hind ones distinctly metallic, their hair white, that on the inner side 

 of hind basitarsus fuscous ; abdomen with a fine sculpture, running 

 into delicate transverse striae, which have a wavy appearance ; seg- 

 ments covered with a very fine white tomentum, shining in favorable 

 lights ; apex with black hair ; venter with white hair ; fifth ventral seg- 

 ment green. 



By the armed postscutellum this is allied to P. vigilans, 

 but it differs in color, venation, sculpture and the character 

 of the postscutellar process.

Paracolletes plumosns (Smith). 



Victoria (C. F., Turner collection). On the right side the 

 first r. n. enters middle of second s. m., but on the left it 

 enters at the end of the first third. This variation increases 

 the probability that P. plumosellus Ckll. is the male of plu- 

 mosns, but nevertheless I believe it is distinct, as I have 

 before me another male which must surely be veritable 

 plnmosus. This insect is like plumosellus, but larger (expanse 

 18^ mm.), with the head and thorax a yellower green (essenti- 

 ally as in plnmosus), the vertex and much of scutellum 

 and hind part of mesothorax with dark fuscous hair, the 

 anterior tibiae bright red in front, and the other tibiae and 

 tarsi partly red. The tongue is colletiform. This male 

 plumosus is from Melbourne, Victoria (Rolle; Berlin Mu- 

 seum).
