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



Am Isl., &c. It ranges soutli into Australia, and I have a 

 specimen from Cliina which I cannot distinguish from the 

 Australian examples. Nevertheless, in the moist tropical 

 islands of the Malay Archipelago it has developed several 

 distinct forms, which are probably constant and for the most 

 part confined to particular islands. Material for the satis- 

 factory presentation of the matter is wanting, but the following 

 specimens are in the British Museum : — 



(1) A. zonata ichifeheadi, subsp. n., ? . Cape Engano, 



Luzon, Philippine Islands (Whitehead). — Expanse 

 about 20 mm.: abdominal bands pure deep purple, 

 without any trace of gieen ; hair on outer side of hind 

 tibia? creamy white, witli a dark fuscous basal patch ; 

 thorax unusually small. 



(2) A. zonata borneensis, subsp. n., J. N.W. Borneo; 



" Spitang R." (95-226). — Expanse 21 mm.: abdo- 

 minal bands blue, tinged with green, strongly metallic ; 

 hair on outer side of hind tibia? mostly black anteriorly 

 ■ and white posteriorly, without any yellowish or fulvous; 

 last ventral segment keeled. 



(3) A. zonata andrewsi, subsp. n., £ . Tjigombong, Java 



(C. W. Andrews). — Expanse about 20 mm. : abdo- 

 minal bands metallic yellowish green, witli coppery 

 tints; hair on outer side of hind tibia? light fulvous, 

 with a white apical brush. The hair on head and 

 thorax above is bright fulvous mixed with black, 

 whereas in borneensis it is dull and rather greenish 

 mixed with black, giving a general blackish effect. 

 The tegula? in borneensis are very dark, with a 

 slight coppery lustre ; in xohitehtadi they are dull 

 but not daik ferruginous ; in andrewsi they are as 

 in lohiteheadi. 



Two females of andrewsi come from N.W. Borneo 

 (95-226). One of these, labelled Spitang R., April 

 1895, has expanse nearly 24 mm., and colours 

 exactly as in andrewsi ; the hind tibiae have light 

 fulvous hair on the outside, with a basal black streak. 

 The other, from Kina Balu, is rather smaller, and the 

 abdominal bands are a more brilliant, distinctly 

 peacock-green. There is, however, no important 

 difference. All these insects have the wings strongly 

 dusky. 



The occurrence of andrewsi in Java and Borneo, 

 and of both andrewsi and borneensis on the Spitang 

 River, is contrary to expectation, and may indicate
