Description of a new Species of the Homopterous Genus 

 Aphdznufrom Sumatra. By ARTHUR G. BUTLER, F.L.S., 

 F.Z.S., &c. 



THE species which I here describe was obtained last year by 

 purchase, and it struck me at once as a very beautiful and new 

 Homopteron allied to Aphcena submaculata ; but upon showing 

 it to my friend Mr. W. L. Distant, I found that he was ^ in- 

 clined to regard it as a very fine and highly coloured variety 

 of that species, though without careful comparison of the 

 structural details of the two insects he was not prepared to 

 declare absolutely that they were not distinct. This, after a 

 minute examination of our specimens, I am fully convinced 

 to be the case, and therefore I do not hesitate to describe the 

 species.

General form of A. submaculata) but the tegmina relatively 

 broader across the middle, owing to the greater arch of the 

 costal margin* the outer margin is also very decidedly 

 longer, forming an oblique straight edge instead of an arch 

 continuous with that of the apical portion ; the apex, there- 

 fore, is more prominent than in A . submaculata. The thorax, 



* This I have proved by careful measurement, the difference in width 

 between the middle and the widest part in these wings being exactly 

 2 inillirn. both in the larger and the smaller insect : to an artistic eye 

 the different outline is most marked.
