22 Mr. T. D. A. Cockerell — Descriptions and 



Meroglossa haxidinensls (Ckll,). 



Tlie tongue of Prosopis haudinena'is lias not been examined, 

 l)ut from ils evident affinities the insect must be a Meroglossa. 

 A new localify is Port Danvin, Dec. 1902 {Turner). 



Meroglossa reginarum (Ckll.). 



The male closely resembles the female, but the face is 

 narrower. The wings are quite conspicuously dusky and 

 the tubercles are with or without a small light spot. 



Taken by Mr. Turner at Mackay, April 1900, at flowers of 

 Xanthorrhopa. (No. 621.) 



Meroglossa perviridis cassicefloris^ subsp. n. 



$ . — Length a little over 10 mm. ; expanse about 18. 



Agrees with perviridis in nearly all respects, but- larger, 

 with all the light markings creamy white and the flagellum 

 dark, faintly brownish beneath. It is very like M. reginarum^ 

 but averaging a little larger and more robust, and easily 

 separated by its green colour and perfectly clear wings. 



Hah. Mackay, Dec. 1899, at flowers of Cassia {Turner, 

 270). Also two collected May 1900. British Museum. 



The original type oi reginarum was numbered 270, but ia 

 the present collection reginarum is 621. 



Meroglossa luxuriosa, sp. n. 



9 . — Length about 12 mm. ; expanse 18^. 



Biilliant green, at first sight similar to Ji./7eryinV/s coss/ce- 

 foris, but easily separated as follows : — Face broader ; 

 creamy white face-maikiiigs reduced to a narrow band along 

 each eye and a spot between antenna ; no light stripe along 

 posterior orbits ; mesothorax dullish, densely punctured ; 

 ecutellum much more closely punctured; middle of area of 

 metathorax rugose. Legs without light markings. Wings 

 distinctly dusky, especially in apical field. 



This is in reality nearest to M. varicolovy from which it 

 diff'ers by being larger, without the varied rose-purple tints 

 (the face is often flushed with purple), while the border of 

 the prothorax is wholly green. The thorax is entirely 

 without light markings. 



(J. — Similar to the female, but smaller and more slender; 

 yellower green ; face narrower, with a cream-coloured triangle 

 on apical part of clypeus ; mandibles with a cream-coloured 

 stripe and labrum with a small spot ; scape with a minute
