﻿BEES OF THE GENUS NOMIA FROM AUSTRALIA. 119 



cerning their history is contained in the following passage from 

 Stephens : — " This species appears to be very rare in this 

 country. I have hitherto seen, so far as I remember, two 

 examples only, which are in my own collection, and were found 

 in the vicinity of the Metropolis in the autumn, I believe at 

 Hampstead " (lUus. Brit. Ent. Mandib. vi. p. 13, 1835). 



In 1850, J. C. Dale presented to the British Museum, 

 among other insects, a pair of Metrioptera from Parley Heath, 

 Hants, which were believed to be " Acrida hrcvipennis,'' Charp. 

 ( = M. rocselii, Hagenb.), and were referred to under that 

 specific name in Walker's Cat. Derm. Salt, in B. M., part ii., 

 p. 256 (1869). In the Museum collection, however, the speci- 

 mens stand over the name hrachiiptera, Linn., and Dr. Burr has 

 kindly informed me that they are correctly placed. 



Assuming that Mr. Waterhouse's specimens were taken in 

 July, it follows that the ascertained seasonal range of roeselii in 

 this country extends from the latter part of that month to 

 September 13th, the date noted by myself. Judging by analogy 

 with allied species, however, our insect might be expected to 

 survive until about October.

SOME BEES OF THE GENUS NOMIA FKOM 

 AUSTRALIA. 



By T. D. a. Cockerell. 



Nomia flavoviridis, Cockerell. 



I HAve before me a series of eight males and seventeen females 

 collected by Turner at Mackay, Queensland ; some of the females 

 from flowers of Cassia and Xanthorrhoea. I have also eight 

 males from Cooktown, October, 1902 (Turner), four males from 

 Townsville (Dodd), and a female collected at Cheltenham, Vic- 

 toria, by French (Froggatt collection, 96). The abdominal 

 bands vary in colour from pale yellowish to white in the males, 

 and in the females are frequently orange. Both sexes are 

 occasionally only rather feebly metallic. So far as can be 

 gathered from Smith's brief account of male N. ceiiea from Port 

 Essington, the only conspicuous and constant difference between 

 that species and N. flavoviridis is found in the hind femora, 

 which in cenea are more slender than in male flavoviridis, and 

 have the apical part much more narrowed and elongated. 



The great variability of N. flavoviridis makes the classification 

 of the varieties difficult. None of the specimens now before me 

 are var. adelaidella, Ckll. The typical flavoviridis is represented 

 only by two males and a female from Mackay, characterised by
