June, igio.l COCKERELL : AUSTRALIAN BeES IN BERLIN MuSEUM. 113 



incomplete hair-bands, most noticeable as lateral patches ; last segment not far 

 from vertical, but curved outward a little apically ; ventral scopa entirely white. 



Related to M. fiilvomarginata Ckll., but smaller, with the cheeks 

 much more densely punctured (more or less grooved), the median 

 process of clypeus larger, and hind spurs yellowish-white. 



Male. — Length about 8-8.5 mm- : the white hair of head, thorax, legs and 

 under side of abdomen abundant and quite long ; flagellum clear ferruginous 

 beneath ; tegulas dark reddish ; wings clear, nervures and stigma ferruginous ; 

 last two segments of abdomen with pale orange hair, and scattered very long 

 white ones ; sixth segment with a broad emargination, the angles bordering the 

 emargination sharp and dentiform, there is also a very small median denticle ; 

 no apical ventral teeth. 



This may be compared with M. tomentella Ckll., but differs by 

 the anterior coxae having well-developed though short spines, the 

 flagellum red beneath, the ferruginous nervures, etc.

 females, 3 males. The species is based on the female ; the associated 

 males appear to belong to it. The insect is superficially very similar 

 to M. preissi. 

 Megachile pictiventris Smith. 



Mackay, Queensland (Rolle). 

 Megachile lucidiventris Smith. 



Liverpool Plains {Mclly). 

 Megachile quinquelineata Ckll. 



Melbourne, A^ictoria (Rollc) ; Eastern Australia (Preiss). 

 Megachile macularis Dalla Torre. 



Port Phillip (Coulon). This is the insect I have always deter- 

 mined as macularis, as it agrees with the description. A specimen 

 from F. Smith's collection, obtained at Sydney, is smaller and has 

 white hind spurs. This must be distinct, and not a true representa- 

 tive of the species. 

 Megachile latipes Smith, 



Sydney (Daniel); Adelaide (Bchr). 

 Megachile henrici Ckll. 



Adelaide (Schomburgk) ; Sydney (Daniel) ; eastern Australia 

 (Preiss). The females are very variable in size; length 12.5 to 

 17 mm.
