dark Irish varieties. Of two females taken, one is also dark, but the 

 other a singular pale variety, the nsual irregular transverse central 

 line or shade being absent, the middle of the wings is occupied by a 

 broad band of oblong pale yellow blotches. It is, therefore, a very 

 liandsome aberration, but apparently rather a freak of nature than a 

 cliinatal variation. 



Lasiommatn uSSqeria. — Blacker and more velvety than usnal, and 

 in the female with smaller pale yellow spots in the fore-wing. This 

 is especially noticeable in lanes near the sea. 



Sntijrus Titlionus. — Also apparently affected by the neighbour- 

 hood of the sea. In this species the male is the variable sex, the dots 

 on the under-side of the fore- wings being reproduced on the upper- 

 side. In the typical form only one of these spots, near the anal angle 

 of the hind-wing, is visible as a white-centered black spot on the upper- 

 side. Here I have taken specimens having respectively two, three, 

 and four of these dots on the upper-side, and in one or two instances 

 all are white-centered. One of them has also two additional spots on 

 the upper-side of the yore-wing ; another has two on one side and one 

 on the other ; and another male has no dots at all on the upper-side 

 of either fore or hind-wings, and the apical round black spot has but 

 one faint white pupil. In fact, of a dozen specimens, no two are quite 

 alike, but they are picked out fi*om among numbers of the ordinary 

 type. In the female I find no variation beyond an occasional second 

 dot on the hind-wing. 



Lycccna Arc/iolus. — One female specimen has a very hroad 

 dark border. 



On the other hand, Sntyrus Hyperanthus and Janb'a, Lyccena 

 Alexis (Icarus) and pkloeas, all of which present curious aberrations 

 in various parts of the South and East of England, although very 

 abundant in this district, appear to be restricted to their normal forms; 

 and L. Medon, which is common on the sand-hills, shows no tendency 

 towards its northern variation. 



Of the very few Bomhyces and Gcometrce occurring here, scarcely 

 any present any striking variation. I recorded last year a specimen 

 of Odonestis Rotatoria, of a rich dark chocolate-brown. Those reai'ed 

 this year are nothing like so dark, but resemble the well-marked forms 

 found in the Norfolk and Cambridgeshire fens. 



Abraxas grossulariata is not at all remarkable. Of a hundred 

 reared as an experiment, two or three proved to be dusted over with 

 black atoms so as to look smoky, and the majority had the spots
