202 HYMENOPTERA. 



front very minutely rugosopunctate (with distinct strong punctures on 

 a shining ground in flavomaculatus) ; flagellum ferruginous beneath 

 at base ; hair of front and vertex pale yellowish ; mesothorax dullish, 

 finely punctured all over, very densely at sides ; mesopleura dull and 

 densely rugosopunctate (shining, with sparse strong punctures va. flavo- 

 maculatus); area of metathorax with fine longitudinal rugae ; lower 

 section of basal nervure very strongly arched ; first r. n. meeting 

 second t. c. ; hind tibiae with a moderate, largely pale scopa (nothing 

 like the broad strongly plumose scopa of flavomaculatus) ; abdomen 

 less shining, minutely punctured all over. 



Known from other Australian Halictihy the thoracic patch, 

 the dusky wings, and the black abdomen without hair-bands 

 or spots. The hind spur is finely serrate or denticulate, with 

 numerous little teeth. The posterior truncation of meta- 

 thorax is well defined, its lateral margins sharp. 



Hab. — Mackay, Queensland, March, 1900 {Turner 461). 

 Three females. 



Paracolletes fimbriatmus sp. nov. 



<? . Length about 10 mm. ; head and thorax black, covered with 

 bright fox-red hair, that over clypeus dense and shining golden ; ab- 

 domen rather small, bright ferruginous red, strongly punctured, with 

 a rather marked constriction between first and second segments ; face 

 rather broad ; mandibles bidentate, black with a reddish spot ; tongue 

 colletiform as usual ; antennae ordinary, third and fourth joints about 

 equal, flagellum red beneath ; mesothorax and scutellum shining, 

 strongly punctured ; area of metathorax triangular, with a strong 

 transverse keel ; tegulae shining clear amber-color ; wings clear, faintly 

 dusky at apex ; stigma ferruginous, fairly well developed ; nervures 

 ferruginous, the outer ones darker; marginal cell flattened, almost 

 truncate, at end; b. n. meeting t. m. ; first r. n. joining second s. m. 

 before the middle; legs mainly red, with reddish hair, but femora 

 blackish except apically, and middle and hind tibiae with a large black- 

 ish cloud ; hair of abdomen mostly pale reddish, but short fuscous 

 hair on the more or less darkened hind margins of the segments ; apex 

 darkened ; third to fifth ventrals with broad even fringes of yellowish 

 hair. 



Var. a. — Hair of head and thorax pale ochreous. 



This species is very near to P. fimbriates, which is known 

 only in the female. The color of the teguhe and the better 

 developed stigma seem to indicate that Hmbriatinus is not 

 the male of fimbriatus. 



Hab. — Victoria (C. F. ; Turner collection). British Mu- 

 seum). Two males.
