222 THE ENTOMOLOGIST. 



marked E. Saunders, 93, 49, and 317. The males are marked 

 as follows : (1.) 91. 16, Hy. 316 ; (2.) 91. 16, 317 ; (3.) E. Saun- 

 ders, 93. 49, 317 ; (4.) same as 3 ; (5.) F. P. Dodd, 1902. 319 ; 

 Townsville, 22. 10. 01. 



The Adelaide form of this insect is to be considered the type ; 

 Smith himself remarked on the geographical variation of this 

 species. The Queensland race is readily distinguished in the 

 female by the wholly dark clypeus and the entire hair-band on 

 the second abdominal segment. 



Nomia flavoviridis, n. sp. 

 (? . Length about 7i mm. ; head and thorax dull yellowish green ; 

 abdomen blue-green (largely blue on first segment), with the hind 

 margins of the second and following segments broadly yellow-green, 

 or the yellow-green colour may suffuse the segments broadly ; vertex 

 and mesothorax granulo-punctate ; face and cheeks covered with snow- 

 white hair, that on vertex dull pale yellowish grey ; antennae long, 

 fiagellum dull brown beneath ; anterior part of clypeus pale yellowish 

 hyaline, the edge ferruginous ; apical half of mandibles dark ferru- 

 ginous ; tongue dagger-shaped ; ■ hair of mesothorax and scutellum 

 yellowish fuscous, not conspicuous, hind edge of mesothorax with two 

 patches of white tomeutum ; post-scutellum covered with white tomen- 

 tum ; a large patch of white hair on each side of metathorax, and hair 

 of pleura white ; area of metathorax rather large, covered with ridges, 

 the posterior margin at middle with two slight excavations (as in 

 N. hypodunta, but less marked); tegulfe rufo-fulvous, the inner hind 

 angle pointed ; wings clear, stigma sepia brown, nervures dark brown ; 

 second submarginal cell nearly square, first recurrent nervure meeting 

 second transverse-cubital ; legs with white pubescence ; femora metallic 

 green, the knees ferruginous ; tibite ferruginous with more or less green 

 suffusion ; tarsi entirely ferruginous ; spurs white ; hind femora 

 swollen ; hind tibire broadened, long-triangular, the inner edge sharply 

 keeled ; hind margins of abdominal segments with white marginal 

 bands, that on first represented only by a patch on each extreme side ; 

 venter not dentate. 



Hah. Queensland, 91. 16 ; two specimens, both numbered 

 434. Distinguished from N. (cnea, Sm , by its strongly metallic 

 colours, the stouter femora, and the pure white abdominal hair- 

 bands. 



Nomia flavoviridis var. doddii, n. var. 



(? . Length about 7 mm. ; dark blue, with the third and following 

 abdominal segments olive-green ; legs coloured as in iV. flavoviridis, 

 the tarsi variable, sometimes dark, sometimes quite bright ferruginous ; 

 tongue dagger-like ; second submarginal cell square, the first recurrent 

 nervure meeting second transverse-cubital. 



? . Length about 7^ mm. ; head, thorax, and abdomen entirely 

 dark blue ; apex of abdomen fringed with pale chocolate hair ; anterior 

 half of clypeus black ; legs very dark rufo-fuscous ; mesothorax with 

 minute punctures, and scattered larger ones, in the manner of N. 

 austral tea.
