 \oiiiia nana Sm. 9 (T.). 



Adelaide, Australia. N. ruficornis Sm. (a small black species 

 with red flagellum ; abdomen with light hair-bands) was described 

 from the $ , and is, I feel sure, the mate of N. nana. Consequently 

 the name N. smithella Giboda, proposed because ruficornis is a 

 homonym, is needless. 



The variety of form and color in the genus Nomia (sens, lat.) is 

 remarkable. The following summary of the principal types will be 

 of interest to those who have only seen our American species : 



(1.) Species of the subgenus Paranomia Friese, like our N. foxi. with the hind 

 margins of the abdominal segments brightly colored. 

 Nomia formosa Sm. % , from Celebes, has five green abdominal bands shaded 



with purple; abdomen very coarsely punctured. 

 N. elegans Sm. 9 , from Celebes, has four yellow-green abdominal bands shot 



with Vermillion ; second s. m. almost square. 

 A third species from Celebes ( J ) bears a manuscript name which is preoccu- 

 pied ; it has only three abdominal bands (margin of first segment 

 black), which are light emerald green with pinkish tints. The punc- 

 tures of the abdomen are large and well separated. Length about 

 12 mm. 

 Nomia opulent a Sm., from Morty Island, J, has four abdominal bands, these 

 green, shot with vermillion ; abdomen only moderately coarsely punc- 

 tured ; postscutellum densely covered with ochrey-whitish hair; teg- 

 ulse ferruginous; second, submarginal cell very narrow (it is not so 

 narrow in N. formosa). 



(2.) N. australica Sm. 9- Australia. Abdomen dark bluish or greenish, with 

 two broad bright ferruginous bauds of appressed hair on hind margins 

 of segments 3 and 4. 



(3.) Head and thorax black, abdomen red ; as the African N. rubella Sm. and the 

 much smaller N. serratula Sin. from Natal. 



(4.) Abdomen red and black, with ochreous hair-bands (style of our N. nevaden- 

 sis, etc.). N. floralis Sm. from Hong Kong. 



(5.) N. producta Sm. % (T.). Natal. Abdomen claviform, narrowed basally; 

 second s. m. very broad ; first r. n. joining second t. c. ; b. n. strongly 

 bent, falling short oft. m. ; clypeus greatly produced ; hind tibia with 

 a great white lamina, which bears the spurs. 



(6.) N. nilotica Sm. (T.). White Nile. A smallish red and black species, with 

 enormous milky-white tegulse, reaching from tubercles to corners of 

 metathorax ; metathorax, pleura and most of first two abd. s. red ; face 

 and anterior margin of thorax densely covered with white tomentum ; 

 first r. n. meeting second t. c. ; third s. m. considerably longer than 

 the first. 



(7.) N. nubecula Sm. (T.). Sierra Leone. Eemarkable for having the apical cor- 

 ner of the wing broadly dark fuliginous, sharply contrasting with rest 

 of wing, which is hyaline; wings hairy; face narrow.
