June, 19 lo] CoCKERELL : AUSTRALIAN BeES IN BERLIN MuSEUM. 103 



tibiae, and anterior and middle basitarsi ; hind legs entirely black, the spurs 

 white ; flagellum dull reddish beneath ; tegulae piceous with a small yellow 

 spot ; wings very faintly dusky, nervures and stigma dark ; first r. n. entering 

 basal corner of second s. m. ; mesothorax dullish, rather closely punctured; 

 abdomen strongly and closely punctured. 



In the table of Prosopis this runs to P. clongata, from which it is 

 easily known by the ordinary (not constricted) abdomen, and the 

 markings of the mandibles and legs. The following insect seems to 

 be its female : 



Female. — Length 9 mm. ; mandibles, labrum, tegulse and legs without 

 yellow ; clypeus black ; lateral face-marks semilunar, ending in a moderately 

 acute angle on orbital margin. In the table this runs to P. simillima Smith, 

 which has a quite different male. 



Habitat. — Type (male) from Melbourne, Victoria (Rolle). Fe- 

 male from Australia, Berlin Museum, 1748. Type also in Berlin 

 Museum. 



Prosopis indicator, new species. 



Male. — Length about 10 mm. ; black marked with red and bright chrome 

 yellow ; the legs, except the trochanters and the infuscated hind tarsi, wholly 

 bright chestnut red ; labrum, mandibles, lower and lateral edges of clypeus, 

 and lower half of cheeks dull red ; antennae red, not very long, flagellum 

 darkened above ; clypeus, except the red margins, a narrow triangular supra- 

 clypeal mark, and lateral marks, all bright yellow ; the lateral marks end con- 

 siderably above the level of the antennae in a rounded lobe, from the orbital 

 side of which comes a linear upward projection, the whole simulating a closed 

 hand, with a short index finger pointed ; projecting upper edge of prothorax 

 broadly, tubercles, squarish patch behind, subpyriform patch above tubercles, 

 spot on the ferruginous tegulje, axillae, scutellum and postscutellum, all bright 

 yellow ; abdomen pointed, the first two segments red, the others black ; second 

 segment clouded with blackish ; first segment gibbous above, base of second 

 depressed ; wings perfectly clear, nervures and stigma dark brown ; first r. n. 

 meeting first t. c. ; mesothorax dull, with feeble punctures, abdomen roughened, 

 with punctures of different sizes. 



Female. — -About the same size and general appearance, noticeable for the 

 pointed abdomen ; the red is reduced to a chestnut-red suffusion on labrum 

 and mandibles, a dark red suffusion over antennae, apical half of anterior 

 femora, practically all of middle femora except above, anterior and middle 

 tibiae in front, anterior tarsi, small joints of middle tarsi, and first two seg- 

 ments of abdomen except the broad black apical margins ; the yellow is 

 reduced to broad lateral face-marks (obtuse above, and notched by antennal 

 sockets), tubercles, scutellum except anterior margin, and postscutellum except 

 sides. The front in both sexes is coarsely rugosopunctate.
