Megachile abluta, sp. n. 



? . — Length 9i— 10^ mm. 



Size, colour, and appearance exactly as in M. rixator, but 

 readily separable by the folloMdng characters : hair of last 

 ventral segment black ; hair of vertex fuscous ; clypcus 

 densely punctured, Avithout any median smooth line ; fiagel- 

 lum not red beneath ; hair on inner side of tarsi very pale ; 

 ventral scopa usually paler, the basal half white ; otherwise 

 the two are essentially the same, 



^ . — Length 7-9 mm. 



Face densely covered with pale ochreous hair ; flagellura 

 black ; anterior coxae with short black spines ; anterior tibiae 

 and tarsi simple, the tarsi red at apex ; sixth abdominal 

 segment bilobed, the lobes rounded, the dorsal surface with 

 a large kidney-shaped dense patch of pale hair; no subapical 

 ventral teeth. 



This male looks just like the Australian M. sequior, Ckll., 

 except that it lacks the thoracic hair-spots conspicuous iu 

 sequior. It is even more like the European M. npicalis, 

 which is without the hair-spots, but M. abluta has a fairly 

 evident pallid band in the scutello-mesothoracic suture, 

 wanting in apicalis. In apicalis the margin of the sixth 

 abdominal segment is denticulate, which is not at all the case 

 in abluta. The kidney-shaped patch of hair is more extensive 

 in apicalis, almost entirely covering the dorsal surface of the 

 sixth segment. 



Hab. Formosa (Sauter). 31 females and 34 males in 

 Berlin Museum. The type is a female from Takao, Aug, 23, 

 1907. All the females come from Takao, July to October. 

 The males bear the following data : Takao, May 3_, and July 

 to October ; Taihanroku, June and July ; Koroton, Sept. 8; 

 Kagi, Aug. 29. 



Megachile subusta, sp. n. 



c?.— Length 11-12 mm. 



In nearly all respects exactly like the male of M. rufo- 

 vittata, but with the hair of the vertex and thoracic dorsum 

 entirely ferruginous, without any fuscous or black. On the 

 disc of the mesothorax the punctures are close, yet the 

 shining surface is clearly visible between them, whereas in 

 rujuvittata this is not the case. The abdomen is much less 

 closely punctured than in rvfovittata ; thus the disc of the 

 fourth segment is closely punctured in rvfoviftata, sparsely
