Prosopis extensa sp. n. 



9 . Length about 4 mm. ; slender, with long metathorax and 

 subclavate abdomen, looking like some small Pemphredomd wasp; 

 black, the front with an extremely obscure greenish tint; the thorax 

 dull, with the prothorax, pleura and posterior face of metathorax 

 shining; abdomen shining; head not far from round in front view; 

 mandibles, labrum, linear lateral face marks ending about level of 

 antenna?, lower margin and greater part of disc of clypeus yellowish- 

 ferruginous, the pale color on clypeus ending suffusedly above; 

 labial palpi with the second joint remarkably short and stout, almost 

 globose, the third and fourth cylindrical, the third twice as wide as 

 the fourth; maxillary palpi with the basal part stout, the second 

 joint longest, the sixth tapering at end; antennae rather slender; 

 scape yellow in front, flagellum pale ferruginous beneath; front 

 minutely punctured; vertex elevated, rounded; narrow (ridge-like) 

 upper border of prothorax and the tubercles white; mesothorax 

 densely sculptured with minute punctures and strise; area of meta- 

 thorax very large and long, minutely cancellate; legs black, the 

 anterior tibiae pale ferruginous in front; tegulae piceous; wings 

 hyaline, nervures and the large stigma piceous; b. n. falling far 

 short of t. m. ; first r. n. reaching first s. m. a considerable distance 

 from its apex; second s. m. very small, quadrate; abdomen with 

 microscopic transverse lineolation. 



Hab. — Mt. Yule, Healesville, Victoria, on Eucalyptus calophylla 

 rosea, Feb. 20, 1915 (R. Kelly; Brit. Museum). A very peculiar 

 little insect, with Euryglossina venation. It is perhaps most like 

 P. scintilliformis Ckll., from which it is known at once by the venation. 

 It is by no means a typical Prosopis. 

 Prosopis aralis sp. n. 



9 . Like P. perhumilis (which was collected on the same plant 

 at same time and place), but the white face-marks are extended, the 

 broad clypeal band having below (on apical margin of clypeus) a 

 transverse narrow band extending on each side at right angles, while 

 the supraclypeal area has a broadly triangular light mark, the 

 clypeal marking thus resembling an altar with pedestal at base, the 

 offering represented by the supraclypeal mark; hind tibiae with more 

 than basal third pale; all the basitarsi cream-color. The basal 

 nervure nearly reaches t. m. 



Hab. — Mt. Yule, Healesville, Victoria, on Eucalyptus calophylla 

 rosea, Feb. 20, 1915 (R. Kelly; Brit. Museum) 2 9 . Possibly a 

 variety of P. perhumilis, but apparently distinct. In the coloration 

 of the legs it resembles P. accipitris Ckll., from Tasmania.
