and a J from coll. Capron. Probably it is the zonula of Cam. {nee Kl.). The 

 true zonula, Klug, is common in Switzerland and South Europe, but I cannot 

 certify it as British. It is very like distinguendus, but {inter alia) differs by 

 having the hind femora almost entirely yellow, only their actual apices being 

 black in either sex. 



A. amcenus, Gravenh. (= einguluni, KL, Cam., Andre, &.C.). Seems to be 

 commoner than distinguendus, but still decidedly rare. It occurs in Surrey and 

 Sussex (Capron, Bloomfield, &c.). A J in coll. Capron has the 5th abdominal 

 segment as well as the 4th entirely yellow. 



T. maculata, Geoffr. The yellow in this species is very apt to become dis- 

 coloured (brown) soon after death. The same is the case with the somewhat 

 similar continental form, T. flava, L. (with yellow antennte!). The latter 

 beautiful species is, I fear, not British ; though it is recorded as such by 

 Stephens, and there is a specimen of it in his collection — probably one of 

 Dr. Leach's Italian captures ! 



T. mandibularis, Pz. Taken by Lt.-Col. Nurse last year in Essex. 



T. fagi, Pz. The antennffi in this species, though long, are distinctly in- 

 crassate before the apex. It is described by Cameron under the name solitaria. 

 Scop. But according to Konow and Enslin the true solitaria = coryli, Pz. — a 

 quite difFerent species. I have many continental specimens of the latter, but 

 do not believe it is British, thoiigh Cameron gives it as such (under the name 

 coryli), on the authority of Stephens. A g of /agi from Pelham Wood, Lincoln- 

 shire, June, 1909, was sent to me for determination by Mr. Claude Morley, (I 

 have taken a ? of it in Germany while visiting the late Pastor Konow.) 



T. colon, Kl. I have seen two ? ? from Yorkshire sent me for identifica- 

 tion in September, 1909, and I think Mr. Bloomfield has also taken it. 



T. velox, F. My British specimens are all from Scotland (Eannoch, Donis- 

 thoi'pe). It is a common Alpine insect.

AGRIADES GRAVE SI, n. sp. : A NEW LYC^NID.

 - (Plates VII, VIII). 



At first glance tliis species resembles closely on the upperside 

 Polyommafus icarus ; on the underside the suggestion is Aricia medon. 

 It is, however, not a Polyommatus or an Aricia but an Agriades, and 

 is, indeed, nearest to A. escheri. It has, in some respects, much resem- 

 blance to A. actinides, of which, however, I have been unable to obtain 

 a male specimen for dissection. From actis it seems very distinct. 



The specimens available are three males and one female. One 

 male expands 27 mm., the other three specimens, 30 mm.
