June, tgio ] CoCKERELL : AUSTRALIAN BEES IN BERLIN MuSEUM. 109 



beneath ; mesothorax and scutellum densely rugosopunctate ; anterior part of 

 mesothorax with a pair of ill-defined short bands of pubescence probably better 

 defined in fresher specimens ; area of metathorax dull, concave in the middle ; 

 tegulae clear rufotestaceous ; wings slightly dusky, stigma ferruginous, nervures 

 fuscous; legs black with pale hair, anterior tibiae in front and small joints of 

 tarsi, rufescent ; anterior tarsi simple ; anterior coxa hairy, with short spines ; 

 abdomen broadly excavated at base ; sixth segment swollen in the middle 

 toward base, its margin truncate, with a rather large rounded black tooth at 

 each corner of the truncation ; seventh without spines. 



Superficially very like M. cygnoruni Ckll., but distinguished by the 

 simple anterior tarsi. There is a strong general resemblance to the 

 European M. apicalis, but the Australian insect is larger, and the 

 apical structure of the abdomen is different. 



Habitat. — Adelaide (Schomburgk). Berlin Museum, 20640. 



Megachile semicandens, new species. 



Male. — Length about 7 mm. ; black, with the abdomen beyond the second 

 segment entirely bright apricot color ; the second segment has the hind margin 

 red, and three suffused spots, one in the middle, and one on each side, 

 confluent with the red of the margin ; antennae long and slender, the 

 flagellum dull reddish beneath ; tibias and tarsi reddish-brown, the anterior 

 tibiae ferruginous in front ; head longer than broad, broad-oval ; eyes purplish ; 

 face densely covered with white hair ; hair of head and thorax above thin, 

 dull whitish ; cheeks and vertex rather large ; tegulae fuscous ; wings nearly 

 clear, the stigma and nervures ferruginous ; anterior tarsi simple ; anterior 

 coxae without spines ; sixth abdominal segment vertical, its margin with two 

 widely separated teeth ; seventh without spines. 



Resembles M. abdominalis Smith, but distinguished by the color 

 and structure of the abdomen. There is a strong superficial resem- 

 blance to certain forms of Osmia, as O. andrcnoidcs, but there are 

 no pulvilli. 



Habitat. — Adelaide (ScJiombitrgk). Berlin Museum, 19407. 



Megachile phenacopyga, new species. 



Male. — Length 1 1 mm., the abdomen short ; exactly like M. chrysopyga 

 Smith, except as follows : face broader, the dense hair covering it pale yellow- 

 ish, shining white on clypeus ; apex of anterior femora and outer side of tibiae 

 not black, but with a little blackish stain ; anterior tarsi cream-color, broadly 

 dilated, the first joint fringed on inner side with fuscous hairs, the others with 

 ferruginous, the long white hair of the hind margin tipped with black or 

 fuscous ; apical tooth of mandible longer. 



Habitat. — Eastern Australia (Prciss). Berlin Museum, 1004.
