II.— PAETHENOaENESIS IN ERIOCAMPA ANNULIPES. 



During the past summer aud autumn the larva) of Eriocampa 

 annulipes Lave been excessively abundant on some of the beech and 

 i hawthorn hedges round Sale ; and have proved very destructive to 

 them by eating the epidermis of the leaves. In one place in particular 

 the leaves have had almost every particle of epidermis taken off, thus 

 causing them to become curled up, and useless so far as being able to 

 afford nourishment to the plant. Being so common, I thought that I 

 would experiment to see if the species was parthenogeuetic, like jEJ. 

 ovafa, &c. I find that it is so, having bred males from virgin females. 



Eriocampa annulipes has a wider range of food plants than any 

 of the other species. It feeds on willows, birch, oak, lime, beech, and 

 hawthorn. 



III.— NOTE ON THE EYMENOPTERA OP THE HAWAIIAN ISLANDS. 



I regret that, owing to my copy of De Saussure's " Etudes sur 1. 

 fam. d. Vespides " wanting some leaves (a fact I have only recently 

 discovered), I have omitted in the paper by Mr. Blackburn and myself 

 ("Memoirs of the Lit. and Phil. Soc. of Manchester," 1886) reference 

 to two species of Odynems described in that work (vol. iii, p. 289), 

 namely, 0. nautarum and O. sandwicliensis. The former, I think, is 

 identical with 0. insulicola ; the latter certainly = O. ruhritinctus, 

 Smith. The species described by De Saussure are in the British 

 Museum. 



I wish also to point out that Tapinoma melanocephalum is found 

 in Australia, as well as in South America, /. c. p. 231.

LEPIDOPTERA ON CANNOCK CHASE. 

 BY CHAS. G. BAEEETT, F.K.S. 



I had the good fortune this year to spend the month of June in 

 Staffordshire, and as my evenings were at my own disposal, it will 

 readily be supposed that the fine wild district of Cannock Chase was 

 not neglected. 



For three weeks the wind was almost constantly cold, and some- 

 times very strong, and this appeared to be a great hardship, but in 

 reality was almost an advantage, for although moths emerged slowly, 

 they were hardy species, and did emerge, and w^ere compelled to
