A male in the National Museum from Buffalo Mountains, Vic- 

 toria, differs from Miss Ricardo's description in having bright 

 red hair at sides of thorax above wing roots. In a specimen 

 from Stradbroke Island, Queensland (collected by H. Hacker, 

 kindly given me by G. F. Hill) these hair tufts are bright golden 

 yellow. The thorax in the Victorian specimen is also browner 

 in colour. In both specimens there is a narrow. grey line on each 

 side of median area of thorax, in anterior half only in the Vic- 

 torian specimen, in the Queensland specimen extending to 

 posterior border, but widening out and becoming less distinct pos- 

 teriorly. 



Pelecorrhynchus fulvus, Ricardo.

Two pairs agreeing with Miss Ricardo's description have re- 

 cently been given me by Mr. H. W. Davey, from Bright, Vic- 

 toria. 



One of the females differs from the other in the deeper reddish 

 tint of the russet colouring of thorax and abdomen, and in having 

 the first abdominal segment dark reddish brown instead of uni- 

 colorous with the rest of the abdomen. The differences are hardly 

 specific. The two males agree with the other female, though both 

 are smaller. As the mal_e does not appear to have been described 

 1 append a short description. 



cf Long: — 12.5 mm. 



Face, black with black hairs, cheeks with long white hairs. 

 Eyes widely separated, the forehead as wide as in female. Thorax 

 and scutellum as in female. Abdomen shining black, first seg- 

 ment with long grey pubescence, the remainder with depressed 

 black pubescence, sides of segments with fringe of white hair 

 tufts. Legs and wings as in female. 



In one of the males there are a very few reddish hairs inter- 

 mingled with the black pubescence.

Two females under examination appear to belong to this 

 species. The front, however, is not narrowed to .vertex, .the
