(as described by Smith) is represented by a male from Ararat, 

 Victoria (Rollc). In this the second joint of anterior tarsi is pro- 

 duced into a great ferruginous lobe, and the first joint has a smaller 

 apical ferruginous lobe. The other joints are creamy-white. In 

 both species the anterior femora are striped with black on inner side 

 at base, and there is a patch of red hair on anterior coxae. A female 

 M. chrysopyga is from Sydney {Darnel). Another is from Port 

 Philip (Coulon). It differs by the pale yellowish (instead of deep 

 ferruginous) hair of the face, and may possibly be the female of 

 phenacopyga, though it seems otherwise to be a chrysopyga. 

 Megachile vestitor, new species. 



Male. — Length about 14 mm., parallel-sided, black, resembling M. 

 lucidiventris Smith in size, form, and the arrangement of the pubescence, but 

 very distinct by the wings, which are clear hyaline except the apical field of 

 the anterior ones, beginning about the end of the first s. m., which is occupied 

 by a rufo-fuscous cloud, dilute below, but dark above, in and beyond the 

 marginal cell; the venation also differs from that of lucidiventris, the b. n. 

 falling considerably short of the t. m., and the second s. m. being very much 

 shorter, with the first r. n. joining it as near to the base as the second to the 

 apex : in consequence of the difference in the length of the second s. m., the 

 marginal cell projects much more beyond it than in lucidiventris. The 

 abdomen is shining, with strong well separated punctures ; in lucidiventris it is 

 dullish and very densely rugoso-punctate. Head large, round seen from in 

 front ; eyes dark greenish ; inner orbits parallel ; face densely covered with 

 brownish-white hair ; vertex with black hair ; flagellum ferruginous beneath ; 

 last antennal joint subtruncate, with a shining apical disc ; mesothorax 

 strongly and densely punctured, with greyish-white hair mixed with black ; 

 hair of scutellum and metathorax dense and greyish-white ; tegulje shining 

 piceous, hairy ; legs black with mostly pale hair, anterior femora with long 

 black hair at base, hidden by pale ; anterior tibise reddish, ferruginous on inner 

 side ; anterior tarsi dark brown, but broadly flattened, the first joint with a 

 large shallow canoe-shaped lobe ; second and third joints with black spots 

 within ; hind margin of tarsi with the usual long fringe, fuscous within ; middle 

 tarsi with very long hair posteriorly; abdomen with pale hair on first two 

 segments ; following two with short black hair, but some glittering white at 

 extreme sides ; fifth and sixth segments with long black hair ; venter with 

 white hair ; sixth segment strongly longitudinally keeled, the apical margin 

 broadly rounded, with a strong central tooth or spine ; no teeth below. 



By the structure of the abdomen, this is related to M. fabricator 

 Smith, but that species is smaller, and seems to be different, judging 

 from Smith's too short description.
