1863.] FROM MADAGASCAR. 65 



ACRiEA OBEIRA, HewitSOD. 



Alis diaphanis ; anticis basi rufo, apice fusco ; posticis dimidio 

 basalt rufo, maculis quindecim nigris, marejine exteriore fusco. 



Upperside transparent, glossy. Anterior wing with the base 

 rufous, the apex brown. Posterior wing rufous from the base to 

 beyond the middle, marked with fifteen black spots ; five at the base, 

 two before the middle, followed at the middle by a curved band of 

 eight larger spots, two of which in the middle of the band touch each 

 other, the outer margin brown. 



Underside as above, except that the margins are much paler and 

 the rufous portion of the posterior wing nearly white. 



I have adopted the name by which Dr. Boisduval has proposed to 

 call this species.

Diadema dexithea, Hewitson. (PI. XI.) 



Alis dentatis, lunuUs margi7ialibus albis ; anticis nigris, in tnedto 

 fascia obliqua lata maculisque quatuor apicalibus albis ; posti- 

 cis dimidio basali albo ; pone medium fascia transversali 

 rubra; margine exteriore nigra. 



Upperside black : the wings dentated, the outer margins with 

 lunules and lines of grey-white. Anterior wing crossed obliquely at 

 the middle by a broad equal band of white, with between it and the 

 anal angle two spots (one minute touching the band) of the same 

 colour ; a band of four small white spots near the apex. Posterior 

 wing with the basal half cream-colour, bordered below with a band of 

 brick-red ; the base, the costal, and outer margins black. 1 



Underside as above, except in colour ; the black of the upperside is 

 below brick-red. The anterior wing has the inner margin broadly 

 black. The costal margin of the posterior wing is interrupted by a 

 white spot. 



In its general appearance this species most nearly resembles the 

 female of D. lasinassa ; in the arrangement of the uervures it agrees 

 with D. dubia and D. anthedon. The cell of the anterior wing is 

 open ; the cell of the posterior wing is closed. 



For the great pleasure of possessing and making known this most 

 valuable and remarkable addition to the diurnal Lepidoptera I am 

 indebted to the kindness of Dr. Sclater. The rich collection of Dr. 

 Boisduval contains the only other example which has, I believe, yet 

 reached Europe.
