sixth segment) broadly rounded, slightly crenulate, weakly 

 emarginate in middle, with a depression or pit just in front 

 of the emargination ; no ventral spine. 



Hab. Cairns, Queensland* " Kur. 1. 02 " {Turner). British 

 Museum. Mr. Turner took M. ustulata, Sm., ? , and M. 

 mystacea (Fabr.), £ , also at Kuranda. 



I do not think M. ustulatiformis can be the male of ustulata, 

 because the female ustulata, agreeing perfectly with Smith's 

 description and my notes from Smith's type, has the shining 

 vertex with large widely scattered punctures. It also has 

 the wings darker, the second a.m. longer and the marginal 

 cell deeper than in ustulatiformis. 



Megachile micreryihrura, sp. n. 



$ . — Length 7 mm. 



Not so robust as M. abdominalis ; head and thorax black, 

 abdomen red, the colour tegumentary ; hair of head and 

 thorax scanty, white, a little yellowish on vertex ; mandibles 

 black, tridentate, not veiy broad; clypeus and supraclypeal 

 area shining but closely punctured; the disc of the broad 

 short clypeus with a pair of low mammiform protuberances; 

 flagellum dark reddish beneath ; vertex, mesothorax, and 

 scutellum very densely rather coarsely punctured ; tegulte 

 very dark reddish. Wings clear, nervures and stigma 

 reddish brown ; legs black, with light hair, small joints 

 of tarsi bright ferruginous ; abdomen well punctured, with 

 scanty short yellowish hair, not forming bands or spots; 

 ventral scopa entirely creamy white. 



Allied to M. abdominalis, but smaller and narrower, with 

 proportionately longer e} r es, and other differences. In size 

 and shape it resembles M. semicandens, Ckll. 



^ . — Looks like the female ; face covered with shining 

 white hair; anterior tarsi simple; anterior coxa? not spined; 

 middle and hind tarsi and small joints of anterior ones red ; 

 thorax above with six white hair-spots, one at each corner of 

 mesothorax, and two in scutello-mesothoracic suture ; abdo- 

 men red, with the lower border of basin of first segment 

 broadly black ; apex (sixth segment) broadly emarginate or 

 very obtusely bilobed (in semicandens it is bidentate) ; no 

 ventral spine. 



Hab. Port Darwin, Nov. and Dec. 1902, 1 ?,2^ (Tur- 

 ner). British Museum. 



The cheeks in the female are narrower than the eyes and 

 rough ; in abdominalis they are broader and shining. Super- 

 ficially this species looks just like Ostnia semirubra.
