profound ; face longer than broad, the central sulcation and trans- 
verse carinations, profound; rostrum about reaching the posterior 
trochanters ; tegmina with the ulnar areas about half as long again 
as the apical areas; wings with six apical areas. 
Long. excl. tegm. 2 60 mm. Exp. tegm. 74 mm. 
Hab. New South Wales; Hay (W. W. Froggatt). 
Mr. Froggatt informs me that this species was taken at Hay, 
“one of our Western districts on the great plains,” found on 
‘the red gum and box timber that fringe the River Murrum- 
bidgerie, and taken in our tent at the experiment station.” 
NEW AND LITTLE-KNOWN BEES. 
By "TD. Ay CockEREnn. 
Ceratina dupla, Say. 
A series of four ¢ and four 2 from Garrison, N.Y. (Hleth 
Cattell) is puzzlingly variable. One very small male has entirely 
dark tubercles, and belongs to the form named calcarata by 
Robertson. Two females are without light face-marks, and are 
regarded as females of calcarata. One female has only a longi- 
tudinal white band on clypeus, and falls close to C. dupla 
halophila, Ckll., differing, however, by being smaller, olive-green 
instead of blue-green, and having a fulvous spot on tegule. The 
other female and three males are true C. dupla. I believe that 
all are forms of a single species; but the matter should be 
further investigated.
