reaching sides of front), broad short mandibles, the thick flattened 

 scape and second antennal joint in front, all pale yellow; upper 

 border of prothorax, tubercles, anterior and middle femora, apices 

 of hind femora, and all the tibiae and tarsi, bright lemon-yellow; 

 scutellum entirely black; face rather narrow, entirely pale up to 

 level of antennae, Supraclypeal area oval with a truncate base, 

 lateral face-marks ending above in an oblique-sided lobe, the tip 

 of which is on orbital margin about the level of middle of front; 

 front and thoracic dorsum dull, extremely minutely punctured; 

 tegulse with a light spot; wings clear, stigma and nervures dark 

 brown; first r.n. entering apical corner of first s.m. or meeting first 

 t.c. (these alternatives represented by the opposite wings of the 

 type); abdomen short and broad, dullish, very finely punctured, 

 wholly without ventral tubercles; flagellum pale ferruginous beneath. 



Habitat. — Purnong, vS. Australia (S. W. Fulton; Nat. Mus. Vict., 

 197). In my table of Australian Prosopis (Ann. Mag. Nat. Hist., 

 Feb., 1910) this runs to P. primulipida Ckll., but differs from that 

 by the much narrower and paler face, wholly yellow hind tibiae, etc. 

 From other species it is known by the small size, yellow legs and 

 non-tuberculate abdomen. According to the character of the 

 mandibles and scape, P. asineUa falls in the genus Gnathoprosopis 

 Perkins. 

 Prosopis minuscula n. sp. 



cJ". Length about 4f mm., very slender, especially the abdomen, 

 which has the dorsal suture between the first and second segments 

 constricted; black, with the following parts yellow (reddened by 

 cyanide in type), mandibles, labrum, the long clypeus, lateral face- 

 marks shaped like feet on tiptoe (convex and extremely shiny), 

 tubercles, small marks on upper margin of prothorax, apical part 

 of coxae, trochanters, knees, stripe on anterior femora behind and 

 short one in front, anterior and middle tibiae (latter with a blackish 

 spot behind) and less than basal half of hind tibiae; the supraclypeal 

 area, scutella, etc., are black, and the combination of black femora 

 with yellow trochanters is very peculiar; scape yellow in front, not 

 swollen; flagellum long, light fulvous beneath; wings clear, nervures 

 and the large stigma dark brown; first r.n. meeting first t.c; second 

 s.m. about as high as long; abdomen subclavate, broadest near the 

 end. The abdomen is rather coarsely transversely lineolate. 



Habitat.— Croydon, Victoria (S. W. Fulton; Nat. Mus. Vict. 195). 

 Runs in my table nearest to P. primulipicta, which has a much 

 broader face, dark trochanters, etc.
