Pachyprosopis saturnina Ckll. 



Perth, Australia, Feb. 1-7, 1914. (R. E. Turner; Brit. Museum). 

 The markings vary; the yellow at anterior corners of mesothorax 

 may be extended, curving round to make two bands on anterior 

 part of disc; there may be a large yellow extension of lateral face- 

 marks mesad of lower end of facial fovea? ; the scutellum in the Perth 

 form is practically all yellow. 



Euryglossina hypochroma sp. n. 



9. Length about 3.75 mm.; robust, head and thorax shining 

 black; abdomen dark, faintly purplish, above, but clear reddish- 

 yellow below; legs clear yellowish-ferruginous, the anterior femora 

 sometimes mainly black on outer side; mandibles chestnut red, 

 dark at tip; a large yellowish spot on cheeks just above base of 

 mandibles; clypeus and supraclypeal band fulvotestaceous (perhaps 

 yellower in life) ; a very slender fulvous line running up inner orbits 

 as far as facial fovese; scape with a light stripe; flagellum thick, clear 

 fulvous beneath; head large, subquadrate, front convex, shining; 

 tubercles clear yellow; mesothorax shining, with extremely minute 

 and sparse punctures, the disc microscopically cancellate; tegulae 

 testaceous; wings hyaline, nervures and the large stigma sepia; b. n. 

 strongly arched; first r. n. joining first s. m.; second s. m. sub- 

 quadrate; extreme apex of abdomen ferruginous. 



Hob.— Perth, W. Australia, Feb. 1-7, 1914 (R. E. Turner; Brit. 

 Museum.) 2 9 Allied to E. perpusilla (Ckll.), but larger and more 

 robust, with fulvous clypeus, etc. It resembles Pachyprosopis 

 atromicans Ckll., but is easily separated by the color of the femora, 

 much smaller second s. m., etc. 



Euryglossina flaviventris sp. n. 



9. (Type). Length about 3.75 mm.; head and thorax black; 

 abdomen black with a faint purplish tint above, the venter clear 

 yellow, the extreme lateral margins and the apex rather broadly 

 (the light color more extensive than in E. hypochroma) also yellow; 

 legs bright yellow, anterior femora sometimes marked with black, 

 hind tibiae and tarsi dark brown on outer side; mandibles fulvous; 

 a small fulvous spot on cheeks next to base of mandibles; linear 

 lateral face-marks as in E. hypochroma; upper half of clypeus, and a 

 supraclypeal band yellow; antennae fulvous beneath; front shining; 

 mesothorax microscopically tessellate; tubercles yellow. 



c? . Clypeus, supraclypeal area and comparatively broad lateral 

 face-marks yellow, the pattern essentially as in E. perpusilla; the
