arc perhaps (Icnudcd ; the hair ol' the vertex is very sliort 

 and ochraccoiis. 



Hub. Males from Brcwarrina, N.S.W., 1914. (Fror/galt, 

 20G cr=tvpe), and \Voodend, \ ictoria (French ; Frof^gatt eoll. 

 IGU), the hitter with green eyes, and hair of face, top of 

 head and dorsum of mesuthorax strongly yellowish. Female 

 from lirewarriiia {broycjutl, 210 c). The dense band of hair 

 across sixth abdominal segment readily separates the female 

 from M. cetera, CklJ. 



Another male M. captionis, marked " Yarrawin " (Froy- 

 ^r//^, 207 c), looks long and narrow, having the abdominal 

 sicgnients extended : it has no spot on the outer side of ante- 

 rior tarsus, and there is a slight projection in the middle of 

 the interval between the dentiform projections of the sixth 

 abdominal segment. The flagellum is rich chestnut-red 

 beneath. According to the list accompanying the specimens, 

 the "Yarrawin'' material is from Brewarrina, whicli is on 

 the Barwon II., over 360 miles from the coast and about 

 GO miles from the Queensland border.

 black, densely punctured ; abdomen clear Ijriglit ferruginous, 

 tlic first t-egment with the basin (except upper part) and

 at each corner of mesothorax, the posterior ones con- 

 spicuous) ; sixth abdominal segment bidentate, the short 

 tubercle- like teeth wide apart. The head is large, broader 

 than the thorax. Flagellum slender, dull red beneath.
