NEPTICULA RUBlVORA. 31$ 



towards the end of April. Nolcken says that he has no doubt there is 

 a summer brood, but has never obtained it. On the other hand, the 

 autumn larvae, from which the spring imagines come, are exceedingly 

 abundant, 30 mines sometimes occurring in a leaf. They always 

 appear in little colonies, and seem to dislike very shady spots.

Original description. — The larvae collected by Herr Hoffmann, at 

 Batisbon, on Agrimonia eupatoria, changed to pupae inside the mines 

 (see, Ent. W. Intell., iii., p. 59), and from these I have now bred eight 

 specimens of a new and totally distinct species, which comes next to 

 N. angulijasciella, but is rather larger and more beautiful, the head of 

 a darker red, and the fascia more shining. For this species I propose 

 the name of N. agrimoniae (Frey, Ent. Weekly Intelligencer, vol. iv., pp. 

 43-44). 



Imago. — Head of $ rusty yellowish, of $ , dark brown. Anterior 

 wings 5 mm. ; coarsely scaled, black or blackish-grey in colour, with 

 a central silvery or slightly golden transverse fascia, sometimes angu- 

 lated centrally, at other times broken into two opposite equal-sized 

 spots ; the cilial line forms a curve round apex, and runs to anal 

 angle, the cilia grey with black tips. Posterior wings and cilia pale 

 grey. 



Sexual dimorphism. — The male has the anterior wings more grey 

 than black, and the female has a more decided golden lustre to the 

 otherwise silvery transverse fascia. The frontal tuft in the male is 

 generally rusty yellow, at the neck brownish, whilst in the female 

 this is generally dark brown, yet males do occur with brown, and 

 females with ferruginous, heads (Heinemann). 



Comparison of N. agrimoniae with its allies. — Frey notes N. 

 agrimoniae as being larger, more beautiful, the head darker red, 

 and the fascia more shining than in N. angulijasciella. Herrich-Schaffer 

 notes that N. agrimoniae differs from N. arcuatella and iV. anguli- 

 fasciella by the silvery fascia being quite vertical and parallel to the 

 margin. From N. fregella it is distinguished by its larger size, the 

 head being less black, and the base of the anterior wings less glossy. 

 Heinemann observes that the anterior wings of N. agrimoniae are of
