aberrant Species in the Genus Elackista. 269 



black spots beneath. Both larva and perfect insect appear rather 

 later in the season than those of A. Pfeifferella. 



Expansion of the wings 3 lines ; head, face and palpi golden 

 brown ; antennae fuscous, with whitish annulations ; anterior wings 

 dark golden brown, with a faint purple tinge towards the hind 

 margin ; before the middle is a slender, oblique, hardly angulated 

 pale golden fascia, nearest the base of the wing on the inner 

 margin, but not expanded there; beyond the middle two tri- 

 angular pale golden spots, one on the inner margin, and the other 

 rather posterior to it on the costa ; cilia purplish golden brown, at 

 the tips grey ; posterior wings brownish grey, with paler cilia. 



The larva, which mines the leaves of the dogwood in August 

 and September, is greyish white ;* the head and the second segment 

 are black ; all the other segments, except the penultimate, have a 

 black spot beneath. 



The habit of the larva is precisely similar to that of A. Pfeiffer- 

 ella, but the mine and case are rather smaller, as might have been 

 anticipated from the smaller size of the insect. The perfect insect 

 appears in June. 



3. Antispila Rivillei, Stainton. 



" The ground-colour of the wings is a beautiful black ; each is 

 adorned with four triangular silver spots, of which two are on the 

 inner margin, two on the costa." Naturforscher, iv. 21. Hence 

 this insect should be readily distinguished from its congeners by 

 the black (not brown) anterior wings, by the fascia being in- 

 terrupted and by the markings being silvery (not golden). 



The larva mines the leaves of the vine in July, forming large 

 blotches, in which it cuts out a flat oval case, which it suspends 

 to the leaves or stems of the vine. The perfect insects make 

 their appearance in the following month. 



This insect was observed in the island of Malta prior to 1750, 

 and has not been seen since, though M. Millifere, of Lyon, 

 believes that he has seen vine leaves blotched and with holes 

 cut in them (as though by a larva of this genus) ; since, how- 

 ever, M. Milliere's attention has been called to the subject 

 he has not been able to meet with any indications of it. 



Stephensia, n. g. 



This genus is far more nearly allied to Elachista, but the palpi 

 are short and drooping, and the outline of the anterior wings is
