342 Dr. Franz Low on a new 
Family Tortricide. 
Genus ATTERIA. 
Atteria rivularis, n. sp. 
Nearly allied to A. voleanica; rather more golden in colour- 
ing, the black costal area of primaries broader, and the ex- 
ternal border narrower ; the transverse creamy-white streaks 
of costal area longer, and not united to one another at their 
lower extremities ; the branching apical external streaks more 
transverse ; five black spots within the lower half of the cell, 
one or two on the disk near the external margin, and some- 
times several along the inner margin; secondaries with three 
disconnected marginal black spots at apex, and five along the 
external margin: below as above. 
Expanse of wings 1 inch 3 lines. 
Hab. Veragua (Salvin). Two specimens, B.M. 
This species evidently takes the place of the New-Granadan 
A, volcanica at Veragua ; it is a very beautiful insect. 
Amongst the other Lepidoptera presented to the collection 
by Mr. Salvin, I may mention the very beautiful Charidea 
arrogans of Walker, Flavinia leta, and Simena luctifera, of 
which we previously only possessed the types (of C. arrogans 
four examples, and of the other two species a good series) ; 
also two examples of Tostomorpha longivitta, Felder, which 
was not previously in the collection, but only differs in its 
superior size from Walker’s Josia penetrata. 
XLV.—Tylenchus millefolii, x. sp., a new Gall-preducing 
Anguillulide. By Dr. Franz Low *. 
On the lowest leaves of the common milfoil (Achillea mille- 
folium, Linn.), which usually form a small tarf, from spring 
to autumn we find small gall-like inflations, 3-4 millims. in 
length, which are generally seated upon the midrib, less fre- 
quently at the base of the pinne, but always in the neigh- 
bourhood of the apex of the leaf. These inflations, which 
show no means of entrance or exit any where, are covered 
externally by the epidermis of the leaf, and are at first just 
as green as the rest of the leaf and equally hairy. ‘The walls
