by the larvae through openings made in the mine at irregular dis- 

 tances from one another. Hence the mine appears quite white, 

 and the larva moves in it with considerable liveliness. When 

 young the larva is almost transparent, and only betrays its position 

 in the mine by its shining black head and black plate, divided by 

 a very slender central line, on the second segment, and by the 

 dark anal plate ; these characters also remain with the adult larva, 

 but with increasing age the body assumes a distinct sulphur-colour. 

 The segments are rather deeply incised, the dorsal vessel is dark 

 green, the anterif>r legs are of the colour of tlie body, but with the 

 tips darker. The larva seems to quit its abode very readily, and 

 easily forms a new one. When full grown it spins a loose, whitish, 

 elongate cocoon amongst the dead stems and leaves of grass." 



Now we have no evidence yet of the fact that this larva is really 

 that of Cosmopteryx Onclialcea; but we need have no hesitation, 

 from the similarity of its habits to those of the larva found by 

 Herr Hofmann in the leaves of the Hierochloe Australis at Ratisbon, 

 in pronouncing it a Cosmopteryx ; and the probability seems very 

 considerable of its being the larva of that species of Cosmopteryx 

 which had been found in that precise locality, namely, C. Orichalcea. 



The two specimens of C Lienigiella which Dr. Schleich met 

 with were in a different locality. 



I will now glance at the sum total of our present knowledge of 

 the European species of the genus Cosmoj^teryx. 



We have six species, viz. : — 



One with ochreous anterior wings (^Lienigiella) , of which the 

 larva is unknown and unsuspected : 



One with brown anterior wings (Scnba'iella), of which the larva 

 is unknown and unsuspected : both these species have slender, 

 longitudinal, silvery streaks in the basal portion of the wing ; 

 in Lienigiella the margins of the central fascia, which is little 

 yellower than the ochreous ground colour, are silvery ; in 

 Scriba'iella — which has the central fascia dark yellow, inclining 

 to orange, not the rich reddish-orange colour we see in the 

 black species — the margins are pale golden, but the exterior 

 margin is ruptured a little above the middle of the wing, and 

 the orange-yellow colour protrudes through it : and we have 



Four species with black anterior wings, namely —£a;i»u'a, with 

 the base of the wing black, and the apical streak interrupted, 

 of which the pretty red marbled larva mines the leaves of the 

 hop ; Schrnidiella, with the base of the wing black, and the 

 apical streak uninterrupted, of which the pretty red marbled
