﻿BEES OF THE GENUS NOMIA FROM AUSTRALIA. 121 



pleura and sides of metathorax thin and white ; tongue elongate dagger- 

 shaped ; lower half of clypeus, and mandibles except at base, honey- 

 colour ; vertex and cheeks very narrow ; antennae long, the flagellum 

 entirely ferruginous, but darker above ; mesothorax shining between 

 the close small punctures ; basal transverse channel of metathorax 

 shining, crossed by numerous strong ridges ; apical triangle of en- 

 closure small, smooth ; tegulge rather large, apricot colour, the margin 

 paler; wings hyaline, faintly dusky; nervures and stigma ferruginous, 

 first r. n. joining apical corner of second s. m. ; legs with coarse white 

 hair ; knees and tarsi clear ferruginous, tibiae ferruginous at each end, 

 as also anterior pair in front, and hind ones largely behind ; hind 

 femora swollen, shining ; hind tibige swollen, trigonal, but wholly 

 without the median tooth or tubercle found in N. smithella, Gribodo.; 

 abdomen finely but very distinctly punctured, with very broad pale 

 orange hair-bands on the hind margins of the segments except the 

 first, which has only an elongate patch on each side ; venter without 

 teeth or tubercles, hind margin of fourth ventral segment concave. 



2 . Length about 9h or 10 mm. ; similar to the male except for 

 the usual sexual differences ; hair on last two abdominal segments 

 pale purplish-sooty, but the orange bands on the other segments as 

 in the male ; mesothorax with very minute punctures, and scattered 

 large ones ; mandibles dark ; flagellum dark above, clear furruginous 

 beneath ; hair on inner side of basitarsi fulvous. 



Hab. Type (male) from Rutherglen, Victoria, 1909 (French) ; 

 Froggatt collection, 84. Female from Mittagong, New South 

 Wales, January 10th, 1902 (Froggatt, 73). This species re- 

 sembles N. australka, Smith, from which it is easily known by 

 the smaller size and black colour. The first abdominal segment 

 of the female is closely and finely punctured on the disc as in 

 typical australica from New South Wales. 



Noinia kurandina, Ckll. 



I have a male from Kuranda, Cairns, March, 1902 (Turner), 

 and two females from Mackay, Queensland, November, 1891, and 

 May, 1900 (Turner, 1078). The female, not before known, is 

 exactly hke the male except for the usual sexual differences, and 

 the more dilute dark apices of the wings. The clypeus and 

 supraclypeal area show a strong median ridge. The meso- 

 thorax has very fine punctures, with scattered larger ones. 



Nomia semiaurea, Ckll. 



Mr. Turner collected females in Queensland, at Mackay, 

 March, 1900, and at Cairns (Kuranda), April, 1902. At 

 Kuranda, February, 1902, he collected a male N. rufocognita, 

 Ckll. When describing N. semiaurea I suggested that it might 

 possibly be the female of rufocognita, and I am now of the 

 opinion that this is really the case, though actual proof is 

 wanting.
