364 Field Notes. 



Rhododendron ferrugineum, finding the galls of a midge (Perrisia 

 rhododendroni KiefT.), of a mite (Eriophyes alpestris Nal.) and a 

 fungus (E xobasidhim rhododendri) , all of which are well enough 

 known on the Continent, and are of interest to us as following 

 the plant into garden cultivation. I do not know of previous 

 British records. 



Perrisia rhododendroni causes a bud-like gall at the ex- 

 tremity of a twig or branch. I only saw two larvae. 



Eriophyes alpestris (with another species, Phyllocoptes 

 thomasi) exhibits signs of its presence in the longitudinal 

 marginal rolling of the leaves. It also causes double flowers. 



The fungus, Exobasidium rhododendri, causes most re- 

 markable hypertrophies in the shape of cherry-like structures 

 upon the leaves, sometimes attaining the size of a large walnut, 

 pale at first, becoming reddish and shining. It appears in 

 July, is known as the ' Alpine Rose Apple,' and is sweet to 

 the taste. It seldom deforms the leaf and seems to follow the 

 mite-gall. — R. S. Bagnall, F.L.S.

 LEPIDOPTERA. 

 Lepidoptera at Louth. — Convolvulus Hawk Moths have 

 been fairly common this season in Louth and district. The 

 first I saw was brought to me on September 1st, caught in Louth. 

 The Peacock butterfly, which is usually somewhat rare here, 

 has been fairly common, as also has the Red Admiral. — 

 C. S. Cartek, Louth. 



Chserocampa celerio at Scarborough. — On Sept. 13th 

 a neighbour brought me a living Hawk Moth taken at rest on 

 his garden gate. It was a stranger to me, but turned out to be 

 Chcerocampa celerio $. I wrote Mr. H. W. Head, of Burniston, 

 as to the possibility of its being an escape from his ' butterfly 

 farm,' but he replies that he has never once bred this insect. 

 I have the specimen. — D. W. Bevan, Scarborough.

 HYMENOPTERA. 

 Qonatopus pedestris Dalm. , in Cumberland. — The 



interesting note and figure of this insect in The Naturalist 

 (antea p. 276) reminded me that I had captured something like 

 it. I have since had my specimen verified in London as 

 G. pedestris Dalm. I beat it from Elder flowers in July last, 

 on the ' Fell Road,' between Wath Brow and Egremont, in 

 Cumberland. It was very active, running on my beating 

 sheet like a Pezomachus. I should think its habits are pre- 

 darious, its large eyes (occupying the whole of the sides of the 

 head), the muscular anterior femora and peculiar arrangement 

 and form of the tarsal claws suggesting this. Its prey may be
