thorax with thin pale hair; tegulse black in front, dark red-brown 

 behind; wings rather small, clear; b.n. very strongly arched, not 

 nearly meeting t.m.; first r.n. entering first s.m. some distance 

 before its end; second s.m. very narrow, greatly produced above, 

 to an acute angle; legs piceous, slightly metallic, the anterior femora 

 quite blue; anterior knees, tibiae, and tarsi, and all the other tarsi, 

 bright ferruginous red; abdomen feebly sculptured; pygidial plate 

 very narrow. 



Habitat.— Croydon, Australia, 2 9 (S. W. Fulton; Nat. Mus. Vict. 

 236). Quite unique by the uniform dark blue color of the bod3^ 

 Pachyprosopis atromicans n. sp. 



9 . Length about 5 mm.; shining black, with very little hair; 

 tibiae and tarsi bright ferruginous, as also are the knees, extending 

 into a more or less defined stripe on the middle and hind femora; 

 abdomen broad, the lateral hind margins of the segments (especially 

 the second and third) more or less broadly reddish ; mandililes with a 

 ferruginous subapical band; clypeus brilliantly shining, with sparse 

 distinct punctures; scape shining black; flagellum short and thick, 

 clear ferruginous beneath; head not enlarged; mesothorax brilliantly 

 shining, sparsely punctured; scutellum shining and punctured, but 

 postscutellum granular and dull; area of metathorax shining, 

 except at extreme base; tegulse rufous; wings hyaline, stigma dilute 

 sepia, nervures paler, basal nervure yellow; second s.m. broad, 

 but the outer upper angle produced as in Pachyprosopis; recurrent 

 nervures entering second s.m. near base and apex, the first sometimes 

 meeting the t.c, but the second always away from extreme apex 

 of cell; claws with an inner tooth far from tip; hind spur with long 

 spines; abdomen microscopically transversely lineolate. 



cf. Length about 4| mm.; like the female, but the thick flagel- 

 lum is elongated; face whoUj^ black, with thin but conspicuous 

 white hair; red on femora more extended; last two abdominal seg- 

 ments clear red. 



//a6?7fl/.— Purnong, near Murray R., S. Australia, 2 9,16^ (S. W. 

 Fulton; Nat. Mus. Vict. 232, 220, 226); Croydon, Australia, 19 

 (S. W. Fulton; Nat. Mus. Vict. 193). The type is a female from 

 Purnong. Intermediate between Euryglossa and Pachyprosopis; 

 resembling in many ways Euryglossa neglectula Ckll., but especially 

 related to Pachyprosopis nitidiceps Ckll., from which it is known 

 by the shining mesothorax, red tibiae, etc.
