AUSTEALIAN BEES IN THE QUEENSLAND MUSEUM.— COCKEEELL. 265 



Gnathoprosopis simpliciventris n. sp. (? hackeri var.). 

 Male. Agrees with G. hackeri, except that the under side of the abdomen 

 has a pair of low inconspicuous elevations instead of large dentiform processes. 



Brisbane, 6-10-14 (Hacker). This was taken on the same day as a male hackeri, 

 and it seems nearly certain that it is a form of that species, in spite of the great 

 difference and the prominences of the abdominal venter. A final decision can only 

 be reached by observations in the field. 



Gnathoprosopis amiculina n. sp. 

 Female (Type). Resembles G. amicula, but is somewhat less robust, with 

 the anterior and middle tibiae entirely black, and the hind ones narrowly cream- 

 colour at base. The second submarginal cell is shorter, the scape is entirely black 

 (though the flagellum is ferruginous beneath), and the lateral face-marks are more 

 pointed above. 



Male. Described as male of amicula, Mem. Queensl. Mus., V, p. 198. 



The type is from Brisbane, 17-10-16 [Hacker). This is the Brisbane so-called 

 amicula ; renewed study, Avith more material, convinces me that it must be separated. 



Gnathoprosopis hackeri Cockerell. 

 Female. Length about 7 mm., robust, considerably larger than amicula or 

 amiculina ; lemon-yellow lateral face-marks and swollen orange collar and tubercles 

 as in amicula, but the orange of the prothorax is broadly interrupted in middle, and 

 the lateral face-marks are distinctly narrower, obliquely truncate above. Scape black, 

 flagellum ferruginous beneath ; mandibles as usual in the genus ; mesothorax and 

 scutellum finely punctured, but the punctures are distinctly visible under a lens ; 

 anterior tibite rufous on inner face ; hind tibiae with only a small basal cream- 

 coloured spot ; tegulae black ; second submarginal cell large and broad, first recurrent 

 nervure meeting the intercubitus ; abdomen with excessively fine punctures, the 

 basal segment shining. 



Brisbane, 8-10-18 (Hacker). I give a description, as no adequate account of 

 this sex has appeared. 



PROSOPIS Fabricius. 

 Frosopis cyaneomicans nigrescens Cockerell. 

 Bribie Island (Hacker). 



Prosopis eburniella Cockerell. 

 Female. Brisbane, 24-9-18 (Hacker).
