GENUS MEGACEILE AND SOME BABE INSECTS.— HACKEE. 139 



mesothorax, and scutellum with black hair ; there is a small patch of white hair 

 on each side at base of tegula?. Antenna? black, short ; scape about one third the 

 length of flagellum. Anterior wings with apical half pale brown as in male, but 

 the first recurrent nervure enters second submarginal cell nearer to the first 

 transverso-cubital nervure than in the male. Legs black, stout, clothed with 

 black hair; posterior legs very long and stout; hind tibia? and first joint of tarsi 

 densely clothed with black hair on inner side; hind spurs black. Abdomen 

 black, elongate, parallel-sided, with a thin white fringe at apex of each segment, 

 widest at sides ; thick black hair at sides and apex of abdomen ; ventral scopa 

 black. 



The female differs from the male in its larger size, darker clothing, 

 position of first recurrent nervure, and the long posterior legs, which are larger 

 in proportion to the size of the insect than in any other Megachile with which 

 I am acquainted. Described from four females. 



9. M. stiff usipennis, Ckll.— Males, females, Brisbane, September, October, 

 December, January; on flowers of Daviesia ulicina. The male, which has not 

 been previously described, is smaller than the female. Its length is 11 mm. 

 The chief difference between the sexes is that in the male the face is densely 

 clothed with long golden hair ; which on the clypeus is directed downwards, on 

 the front, upwards ; while on the facial fovea? it is directed outwards towards the 

 eyes. Other markings and colours are exactly as in the female. Antenna? black, 

 a little longer than in the female. 



10. M. macularis, D.T. — Males, females, Brisbane, November, January, 

 March; on flowers of Bursaria spi/nosa. 



11. M. abdominalis, Sm. — Males, females, Sunnybank, September, 

 October; on flowers of Jacksonia scoparia. 



12. M. ferox, Sm. — -Males, Brisbane, September, October; on flowers of 

 Daviesia ulicina. 



13. M. heliophila, Ckll. — Males, Sunnybank, September; Kelvin Grove, 

 September; on flowers of Daviesia ulicina. 



14. M. quinquelineata, Ckll. — Females, Kelvin Grove, October, Novem- 

 ber, February, March; on flowers of Daviesia ulicina. 



15. M. simplex, Sm. — Males, females, Kelvin Grove and Sunnybank, 

 September, October, November; on flowers of Daviesia tilicina. 



It will be noticed that a large number of species were taken at flowers of 

 Daviesia ulicina. This plant is a great resort for bees in this district belonging 

 to the genus Megacliile, as it flowers more or less all the summer. I have noticed 

 that they occasionally leave it for some of the Euealypts, but usually return 

 when the Eucalpytus flowers are over. 



16. M. serricauda, Ckll. — Males, Brisbane, February; on flowers of 

 3fesembryanthemum.
