204 HYMENOPTERA. 



but the pubescence is colored more as in P. versicolor. There 

 can be little doubt, I think, that it is properly referred to P. 

 providus, and even the apparent varietal differences may be 

 due to the brevity of Smith's description. The male is evi- 

 dently the insect referred to by me (Ann. Mag. Nat. Hist., 

 Nov., 1905, p. 484) at the end of the description of P. provi- 

 dellus. The head and thorax are wholly without dark hair 

 above. The hind margins of the abdominal segments are 

 very distinctly reddened.

A species with much bright fulvous hair ; apical plate of 

 abdomen pointed. 

 Paracolletes argeiitifrons (Smith), var. a. 



A male collected by Preiss in Western Australia (Berlin 

 Museum, 2562), accords excellently with Smith's description 

 and my notes on Smith's type, except that the second r. n. 

 enters third s. m. some distance from its end, and the third 

 and fourth ventral segments of abdomen have a fringe of 

 fuscous hair. The abdomen is distinctly and finely punctured.

Agrees with type in nearly all respects, but hair of vertex 

 black, apical margin of second abdominal segment with short 

 black hair, abdomen brilliant purple-blue, slightly greenish 

 toward the apex. This may represent a distinct local race. 



Paracolletes nigroclypeatus sp. nov. 



9 . Length 12 mm. ; blue-green, the broad strongly punctured 

 clypeus black, contrasting ; mandibles dark ; face very broad, with 

 much white hair at sides ; hair of vertex largely fuscous, of cheeks 

 white ; flagellum bright ferruginous beneath ; mesothorax strongly 

 punctured, the punctures running in subconfluent rows ; middle of 

 disc purplish, nearly impunctate ; anterior part of mesothorax with 

 some yellowish-green tints ; area of metathorax with a transverse keel ; 

 hair of thorax dull white, with some fuscous on mesothorax, scutellum 

 and anterior part of mesopleura ; tegulse reddish ; wings brownish- 

 hyaline, stigma and nervures reddish-brown ; b. n. meeting t. m. ;
