AUSTRALIAN BEES.—COCKERELL. 89 



not at all expanded at apex (a character separating the species from the related 

 M. ferox Sm.) ; vertex and disc of thorax, including anterior part of scutellum, 

 with dark chocolate hair ; hair of occiput, cheeks, thorax anteriorly and posteriorly 

 and at sides, white ; mesothorax finely and densely punctured ; legs with white 

 hair, fulvous on inner side of hind tarsi ; spurs black ; anterior tarsi moderately 

 expanded, with a large white area in the middle posteriorly, presenting on the under 

 side a large elongate black mark broadly surrounded by white : third joint also with 

 an elongated lateral lobe ; anterior trochanters pointed beneath ; anterior coxae 

 densely covered with white hair in front, not spinecl ; tegulse black, closely punctured ; 

 wings dusky translucent ; abdomen parallel-sided, closely punctured ; first segment 

 with long white hair ; second and third A\-ith white hair- bands, broadly interrupted 

 in middle ; fourth with a bright ferruginous hair- band, failing at sides ; fifth densely 

 covered with bright-red hair, except at extreme sides ; sixth mthout red hair, its 

 transverse keel with two broad rounded lobes, the margins of which are more or 

 less irregular or nodulose. 



Female. Face Mith white hair, but some red hair at apex of clypeus and on 

 mandibles subapically ; mandibles tridentate, the outer face strongly grooved ; 

 clypeus simple and ordinary, very densely punctured ; flagellum obscurely reddish 

 beneath ; conspicuous tufts of wliite hair next to the four corners of mesothorax, 

 and pale hair along its posterior border ; wings very smoky ; legs entirely black ; 

 abdominal segments 1 to 3 mth narrow (linear) white hair- bands, expanding into 

 triangular patches at sides of first segment ; fifth and sixth segments covered with 

 deep coppery-red hair except at sides ; ventral scopa entirely white. 



Swan River, W. Australia, one of each sex {J. Clark). Near to 31. ferox but 

 easily separated by the male antennae, which are like those of 31. erythropyga Sm., 

 a species having entirely different male tarsi. The female resembles M. heliophila 

 CklL, but differs by the colour of the hair at end of abdomen, the entirely opaque 

 mesothorax, the much more finely punctured clypeus, and the minutely and very 

 densely punctured supraclypeal area. The male carries numerous mites on the 

 posterior part of thorax. 



Megachile ciliatipes n. sp. 

 Male. Length about 9 mm. ; extremely near 31. hurandensis Ckll., but 

 differing thus : — No evident spot of pale hair in front of axillae ; no red or fulvous 

 hair on disc of fifth abdominal segment ; anterior tarsi incrassate, especially the 

 basitarsus, and with a fringe of stiff white hair behind ; middle tarsi (which in 

 hurandensis have black hair on outer side and red on inner, with no white) with 

 silky white hair on outer side, and a very long white fringe behind ; hind tarsi with 

 long white hair on each side. The anterior coxae are spined ; face and front densely 

 covered with golden hair ; cheeks with pure white hair, tinged with yellow on upper 

 part ; vertex and discs of mesothorax and scutellum with black hair ; a conspicuous 

 band of pale hair between mesothorax and scutellum ; tegulae black ; wings dusky ; 

 abdomen with narrow pale fulvous hair-bands, disc of sixth segment above densely 

 covered with fulvous hair.
