In the table, the male runs to P. elcgans Smith, from which it 

 differs by its larger size, the quite different face-marks, the red legs, 

 etc. The female also runs nearest to elegans, but differs at once by 

 the black clypeus. 



Habitat. — Mallee, Victoria (Rollc), one of each sex (the male is 

 the type); Adelaide {Schomburgk) , one female, No. 19387. All in 

 Berlin Museum. 

 Prosopis dromedarius, new species. 



Male. — Length a little over 8 mm. ; black, red and yellow ; head and 

 thorax coarsely punctured ; face up to level of antennae entirely bright chrome 

 yellow, the lateral marks extending a little above, ending at an angle of about 

 45° on orbital margin ; labrum largely yellow ; mandibles and malar space 

 dark reddish; mouth-parts normal for Prosopis; palpal joints with lateral 

 apical points ; antennae long, entirely clear ferruginous, apical joint sulcate 

 above ; upper edge of prothorax very narrowly yellow ; tubercles and tegulse 

 red ; scutellum and postscutellum each with a transverse orange patch, that 

 on scutellum much the largest, bar-like ; punctures of mesothorax and scu- 

 tellum very strong ; legs clear red, the trochanters dark ; abdomen roughened, 

 the first two segments red, except hind margin of second, the rest black ; first 

 two segments dorsally strongly gibbous, especially the second, presenting two 

 humps in lateral view ; wings perfectly clear, stigma and nervures testaceous, 

 first r. n. joining first t. c. 



A very distinct and peculiar species, running in the table to P. 

 elegans, but differing greatly in many ways.
