1 have brought a specimen of Anthrocera anthyllidis taken 

 this summer at Gavarnie, with the left mesothoracic tarsus 

 triplicated. Such specimens have not unfrequently been 

 recorded in Coleoptera, but a considerable search in 1910 

 failed to find any such instance in Lepidoptera, so that speci- 

 mens are of extreme rarity. My explanation was then, and 

 remains so still, that the legs of Coleopterous specimens , all 

 pass under review, but those of Lepidoptera are rarely noticed. 

 In this specimen, the anterior of the three tarsi is practically 

 normal, the next two have a broad first joint in common, but 

 the following four joints are nearly normal. Notwithstanding 

 the first joint common to two of the tarsi, the rule of orienta- 

 tion in such specimen pointed out by Bateson seems to hold. 

 As the specimen is set the first and second tarsi are venter to 

 venter, the second and third dorsum to dorsum. I have 

 detected no other abnormality about the specimen. A 

 photograph of the tarsus is reproduced on Plate A. 



I show with it a specimen of A. exulans taken at Oberalp 

 some twenty years ago, Avhich has an abortive wing beneath 

 the left anterior wing, and not only this second but even a 

 trace of a third anterior wing beneath the second. 



Also a specimen of A. achilleae from Zermatt that has 

 symmetrical depressions of the costa of the same character 

 as those in the specimen of Pararge maera shown Oct. 7 by 

 Mr. Wheeler. 



The nervures are all present as in a normal specimen. I 

 had ranged this specimen as of congenital causation and not 

 as a result of any injury. 



Variation in Dianthoecia barrettii and Boarmia 

 REPANDATA. — Mr. L. W. Newman exhibited a long and varied 

 series of Dianthoecia barrettii, bred from wild larvae collected 

 in Co. Cork, and dug pupae from S. Devon. In the Irish form 

 melanic specimens were rare, but in the Devon they were 

 more abundant. A striking point was that the Devon dug 

 pupae had produced, as a series, smaller specimens than the 

 Irish. In the Devon series were three specimens showing 

 an ochreous colour, this form not appearing in the Irish 

 specimens. 



Also a series of Boarmia repandata, all bred from wild
