The publication of Prof. Rebel's figure of hedemanni prevented 

 me from desci-ibing a very closely allied species, found at Tangier 

 in 1901. I have now a considerable series of each, and am 

 acquainted with their larvae. Both feed on species of Malvaceae, 

 making conspicuous blotches on the upper sides of the leaves, and 

 in both instances the larvae assume, before pupating, the beau- 

 tiful transverse bands of scarlet, or rich carmine, so well known in 

 Acrocercops hrongniardellum F. 



The Tenerife species is exceedingly common, feeding on Malva 

 parviflora everywhere, and on Lavatera arhorea in gardens, at 

 Orotava and elsewhere. I have received hedemanni also from 

 Funchal, Madeira {Rev. A. E. Eaton); there is no diflerence 

 between the Tenerife and Madeira sj)ecimens.

When recording Gh'acilaria hedemanni from Morocco [Ent. Mo. Mag. XXXIX. 

 181 (1903)], I was somewhat misled by the absence of a pale basal patch in Rebel's 

 figure. Sucli a patch is distinctly present in hedemanni, but barely traceable or 

 entirely absent from the Tangier insect ; moreover the dorsal spot beyond the central 

 fascia is also absent from what I may now call Acrocercops raalvacea, sp. n. 

 There is also a slight difference in the larvae: in malvacea the scarlet transverse 

 bands are shorter, extending less far laterally, and the head is brown — not blackish 

 as in hedemamii. 1 recorded the food-plant as Lavatera olbia (Ent. Mo._ Mag. 

 XXXIX. 181), but I am unable now to verify this by reference to preserved specimens, 

 which is to be regetted, as I had previously [Ent. Mo. Mag. XXXVII. 236 (1901)] 

 thought the plant "a very large mallow". It was a t&W Malvaceous plant, some- 

 times seven or eight feet high, with broad rounded leaves and white, or lilac, 

 flowers.
