clxx Remarks on certain Species 



Cavpinicolella, Sta. Anterior wings shining, pale tawny, with a 

 basal streak, four costal streaks and three dorsal streaks white, 

 and an apical black streak; posterior tarsi spotted; basal streak 

 very slender, with no dark margin at all, first costal streak not 

 dark-margined towards the base, and extended along the costa 

 towards the base of the wing. 



On hornbeam, in May (and August?). 



I have observed the larva of a Lithocolletis upon the leaves of the 

 hornbeam, which is probably this species ; it mines the upper surface 

 of the leaf in white patches, just as L. coryli mines the hazel-leaves. 



Faginella, Mann. Anterior wings shining pale tawny with a slight 

 grayish tinge, with a basal streak, four costal streaks and three 

 dorsal streaks white, and an apical black streak ; posterior tarsi 

 pure white, rarely with faint fuscous markings ; basal streak 

 with no decided dark margin, first pair of spots with broad 

 and distinct dark margins on the sides towards the base. 



On beech in May and end of July and August. I have bred it from 

 the pupae collected in December and January in beech-leaves. 



Pomonella (defiexella). Anterior wings golden yellow more or less 

 irrorated with fuscous, the basal streak is extremely attenuated, 

 runs along the fold for a third of the length of the wing and is 

 then deflexed inio the first inner marginal streak, the dark mar- 

 gin of which towards the base is interrupted by the prolonga- 

 tion of the basal streak : the first dorsal spot is sometimes pro- 

 longed till it meets the first costal spot, at other times its apex 

 is carried on till it joins the second dorsal spot ; hinder tarsi 

 white, unspotted. Specimens occur in which the prolongation 

 of the basal streak does not take place, but in those cases there 

 is generally an elbow or projection on the first dorsal streak at 

 that place where the connexion would have taken place had the 

 basal streak been prolonged ; in these specimens the first dor- 

 sal streak is likewise sometimes prolonged into the second dorsal 

 streak, sometimes into the first costal streak. 



On blackthorn (Prunus spinosa) in May : not scarce. 



Pomonella {spinicolella). Anterior wings pale golden yellow, with 

 a basal streak, four costal steaks, and three dorsal streaks white. 

 In many specimens none of these marks have dark margins, or 

 at most they are only faintly indicated on the inner sides of the 

 2nd and 3rd pair of opposite spots. The basal streak is long, 

 and reaches fully one third of the length of the wing, its apex 

 frequently rather turns up towards the costa : in some few spe-
