being that it does not mine a large blotch, but mines at first 

 mysteriously down the mid-rib and up again, and only making a 

 blotch of sufficient size to furnish the materials for its case. 



The genus Antispila, besides the two well-known PJeifferella 

 and Treilschkiella, contains the still latent Maltese Rivillei, to 

 which I have previously called attention.* 



1. Antispila Pfeifferella, Hubner. 



In the golden brown anterior wings, with a golden fascia 

 before, and golden opposite spots, beyond the middle, this has an 

 extreme resemblance with A. 2'reitschkiella, being mainly dis- 

 tinguished by its larger size. And it is not a little singular that 

 two species so similar should both feed on the same plant ; the 

 larvae are, however, very different, and can readily be distinguished 

 whilst still within the mine. 



Expansion of the wings 4| lines ; head, face and palpi golden 

 brown ; antennae fuscous ; anterior wings glossy golden brown, 

 towards the hind margin rather coppery ; before the middle is a 

 slender angulated bright golden fascia, broadest on the inner 

 margin, where it is nearest the base of the wing ; beyond the 

 middle are two triangular golden spots, one on the inner margin, 

 the other posterior to it on the costa ; cilia rather coppery, the 

 tips pale grey ; posterior wings greyish purple, with paler cilia. 



The larva, which mines the leaves of the dogwood in June and 

 July, is very pale greyish green, the dorsal vessel greener ; the 

 head is pale brown, and the second segment of the same colour, 

 only a little darker at the sides ; there are no black spots on the 

 under side. 



When the larvsa are full-fed they cut out a flat oval case, formed 

 of the two skins of the leaf, which they fortify with silk and 

 descend to the ground ; the following May the perfect insect 

 appears, and delights to fly round the twigs of the dogwood in the 

 bright sunshine. 



2. Antispila Treilschkiella, Fischer. 



Very like the preceding, only much smaller ; the anterior wings 

 rather darker, the apex less coppery, and the fascia less angulated. 

 The larva is well distinguished by the black head and the row of
