272 LEPIDOPTEBA FROM EAST AFRICAN ISLANDS— HOLLAND, vol. xviii. 



Genus ACH/EA, Hubner. 

 ACHiEA SEYCHELLARUM, new species. 



(Plate VIII, fig. 10.) 



Mfde. — Palpi, front, patagia, and upper side of tliorax fawn color. 

 The upper side of the abdomen is slightly paler fawn. The under side 

 of the thorax and the abdomen is pale fawn, with the anterior legs 

 outwardly darker brown. The fore wings on the upper side are fawn, 

 marked by an incomplete basal black line succeeded by a heavy zigzag- 

 basal transverse line, beyond which in the cell is a small black spot, 

 and at the end of the cell a moderately large ocelliform spot. Beyond 

 the cell, the wing is crossed by a broad black band curviug outwardly 

 opi)Osite the end of the cell, and interrupted more or less on the nerv- 

 ules by narrow, pale lines. Beyond this broad band, there are some 

 submarginal cloudings in a double series, succeeded by minute pale 

 marginal spots. The fringes are white. The hind wings on the upper 

 side are pale gray, with the outer half broadly black. Tlie basal area 

 is separated from the black outer area by an obscurely defined trans- 

 verse whitish line. On the outer margin near the outer angle, at the 

 middle, and Just before the anal angle, are conspicuous white spots, of 

 which that on the middle is the largest. On the under side both wings 

 are pale gray. The primaries have the inner margin broadly shining 

 stramineous. There is a conspicuous black spot at the end of the cell, 

 followed by a curved black ban<l running from the costa to vein 2, 

 and succeeded outwardly near its lower end by a broad black shade. 

 The apical area is slightly darker than the rest of the wing. The (niter 

 margin is very pale gray. The secondaries have a minute spot at the 

 end of the cell, followed toward the outer margin by three obscure and 

 incomplete curved transverse bands of brown, which are lost in a pale 

 brown clouding, which is most conspicuous near the outer and the anal 

 angles. 



Expanse of wings, 55 mm.

ACH/EA SEYCHELLARUM, var. IMMUNDA, new variety. 



This variety only ditters from the type in the total absence, on the 

 upper side, of the primaries, of all the transverse dark markings, and 

 the somewhat paler tint of the under side, and the effacement of most 

 of the less conspicuous markings of the under surface. 



It is well known that in this genus there is great diversity in the 

 markings upon the upper side of the wings, and I have no hesitafion 

 in referring the two forms before me to the same species. There are 

 three specimens of the typical form before me in the collection, all 

 males, and all labeled as coming from Aldabra. There are four speci- 

 mens ot the variety, three males and one damaged female, from the 

 same locality.
