known form of tamarisciata, but much rather with fraxinata, and 

 that for the present I would not venture to locate the imagines ; 

 of course they belong to this group (or species, if Staudinger is 

 right). 



Eegarding the question of food-plants and larval habits of 

 the " pugs," I have had further interesting notes from Mr. Percy 

 C. Eeid. He has discovered that in his district hawthorn — 

 which I gave as a quite exceptional food-plant for the species 

 (Entom. xl. 822) — is regularly favoured by the larvae of Cldoro- 

 clystis coronata, and that in both broods. Mr. Eeid has made a 

 Ijartial reference to this in some recent notes on the season 1907 

 (Ent. Eec. xx. 13), but I think it worth while to quote from a 

 letter which he sent me while my former papers were in the 

 press. He writes {in lift., 27th July, 1907): "In May last 

 I bred some specimens of this insect" [C. coronata] "in a 

 cage containing a number of pupse, beaten as larvae from 

 hawthorn in the preceding August. As hawthorn is not 

 mentioned as a food -plant in any work of reference in my 

 possession, I concluded that by some accident these coronata 

 had found their way as larvas or pupae into this cage, and 

 thought no more of it. But in June last (on the 21st, I 

 think*) I beat a number of Eupitheciid larvae from hawthorn, 

 and wondering what they could be I made a note of the fact. 

 Now they are beginning to emerge as E. coronata.'" To this 

 should be added — from the article in the ' Entomologists' Eecord ' 

 already alluded to — that these were succeeded by a further brood 

 of larvae at the end of August on bramble, one of which produced 

 the imago on September 29th, a member of the very partial third 

 brood which this species occasionally throws. I can also amplify, 

 from the information he has supplied me in correspondence, Mr. 

 Eeid's note on the occurrence on Pastinaca of the larvae of 

 Eupithecia pimpinellata and trisignaria. He writes (iti litt., 

 21st September, 1907) : " It does not do to generalise from one 

 observation, but I noticed that the lyimpinellata occurred on the 

 smaller and more scattered plants on the open down, while the 

 trisignaria were on the larger and more rampant plants along 

 the edges of and just inside a copse. 



I had hoped, ere now, to be in a position to say something 

 about the differentiation, or otherwise, of Eupithecia innotata and 

 fraxinata by the genitalia, but the illness of my friend Mr. Pierce 

 has hindered work in this direction, and if any definite result be 

 arrived at, it must be published in a separate note. 



■■• Mr. Keid has now fixed the exact date as June 20th.
