-LGQ Mr. T. D. A. Cockerell — Descriptions and 



Meyachile cygnorum, Cockerell. 



I am now satisfied that I have at different times confused 

 three species under this name, the males of Avhich are 

 readily separable as follows : — 



Fifth abdominal segment with light hair, except 



at extreme base M. captionis, sp. n. 



Fifth abdominal segment with conspicuous erect 



black hair 1. 



1. Lenjith about 11 mm.; anterior tibije with a 



broad black band covering at least half of 



outer surface longitudinally M, 77iacularis, D. T. 



Smaller ; anterior tibise with a black patch on 



basal half outside 31. cygnorum, Ckll. 



The M. macularis is Turner's 623 from Mackay ; it cer- 

 tainly must belong with the female from the same locality. 

 The original macularis was from Western Australia, but 

 Smith's description appears to point to the species I have 

 identified from Queensland. 



Meyachile captionis, sp. n. 



(^ . — Very close to M. macularis and M. cyynorum, but 

 with the following special characters : — Small, length about 

 9 mm. ; anterior tibise bright ferruginous^ with a large basal 

 black spot anteriorly, not nearly covering half the surface ; 

 second joint of anterior tarsi with a more or kss evident 

 black spot visible from without (as in M. darunniana) ; outer 

 half of tegulae [)ale reddish ; fifth dorsal abdominal segment 

 with erect white or yellowish-white hair. The vertex has 

 the hair entirely pale, not mainly black as in dariviniana. 

 The anterior coxse have an oblique flattened tooth and a 

 patch of red hair. 



? . — Length about 10 mm. 



General appearance of M. quinguelineata, the ventral 

 scopa (white, black on last segment and extreme sides of 

 penultimate) and light abdominal bands practically the same, 

 but the mesothorax much more finely punctured and the 

 sixth abdominal segment with a broad band of dense white 

 tomentum. jNiandibles quadridentate ; clypeus extremely 

 densely punctured, with a minute median apical tubercle; 

 eyes lilac ; flagellum red beneath ; wings hyaline, short ; 

 spurs of hind legs black, but of middle ones red. There are 

 two white hair-spots in the scutello-mcsothoracic suture; 

 the mesothorax and scutellum are almost without hair, but
