AUSTBALIAN BEES.—COCEEEELL. ■ 85 



Female. Looks just the same, seen from above, but the legs, scape, mandibles, 

 and labrum are entirely black, the flagellum also is black, while the light area on face 

 is bright orange, and is confined to a hat-like supraclypeal mark, and a broad 

 P3rriform area on clypeus, including its whole uppsr end, narrowing below, and 

 ending very obtusely just above clypeal margin. 



National Park, Queensland, Dec, 1919, four of each sex (Hacker). I thought 

 this might be a meroglossa, but the second segment of the female abdomen has 

 not the meroglossa base, and the male has not the pointed meroglossa tongue, but is a 

 pollen-eater, as a microscopic preparation shows. The female Palceorhiza, and doubt- 

 less also meroglossa, feed on pollen, but the male must be a nectar-feeder. Thus 

 the differences in the tongue are apparently adaptive. 



The female P. sculptifrons runs in my table of Australian Prosopis (Ami. Mag. 

 Nat. Hist. Feb. 1910) to P.-morosa Smith, to which it is closely allied, differing by 

 the flagellum not being fulvous beneath, and the apical margins of the abdominal 

 segments not discoloured. P. morosa is a Southern species from Victoria. Its male 

 is unknown. 



Prosopis certa n. sp. 

 Male (Type). Length about 8 mm. ; black, robust, with the whole face below 

 antennse, and lateral face-marks ending a short distance above (on orbits, at an angle 

 of about 50 degrees), large spot on labrum, tubercles, scutellum, and postscutellum, 

 all very bright lemon-yellow ; face broad ; mandibles black ; tongue very broad 

 and emarginate ; cheeks with white hair ; scape ordinary, black, punctured ; flagellum 

 long, submoniliform, red beneath ; face dull and pitted ; mesothorax dull and 

 coarsely punctured ; tegulae piceous with a small pale-yellow spot ; wings hyaline ; 

 b.n. falling short of t.m., first r.n. meeting first t.c, second s.m. long ; anterior tibiae 

 broadly, and middle ones narrowly, fulvous in front ; all the basitarsi white ; under 

 side of thorax hoary with white hair ; abdomen shining but rough, with punctures 

 of two sizes ; a strong constriction at junction of first and second segments ; apical 

 margin of first ventral segment slightly elevated in middle. 



Female. Similar, differing thus : — Labrum entirely black ; face-marks confined 

 to broad lateral marks, their upper ends very broad and rounded, a short distance 

 above level of antennse ; legs black, with anterior tibiae fulvous in front ; first r.n. 

 joining first s.m. a little before its end ; end of abdomen with black hair. The second 

 abdominal segment is irregularly punctured, the punctures of different sizes. 



Brisbane (Hacker). Type male 10-10-16 ; female 12-2-18. In my table, 

 the male runs to 51, and falls with P. elongata Sm., from which it is easily separated 

 by the sculpture. The female runs out at 53, disagreeing in the form of the lateral 

 face-marks. 



Prosopis daveyi n. sp. 

 Female. Length about 9 mm. ; black, robust, with large lateral face- marks, 

 tubercles and very large areas on scutellum and postscutellum very brilliant orange ; 

 flagellum ferruginous beneath. The lateral face-marks fill the space between the high
