CHEIMATOBIA MYEICABIA, mihi. 

 A Geometer new to Science. 

 By Nicholas Cookk. 



On the 27th January last I received from Mr. James 

 Edmondson, of Keswick, three Hving pairs of a Chcimatohia 

 which he informed me had just emerged from pupae, and that he 

 found the larvae last summer, spun up in the leaves of sweet gale 

 {Mijrica gale). 



The species is so much like C. hrnmata that I entertained 

 some doubt about it being a distinct species ; but he yesterday 

 visited the spot where he found the larvae, and captured five 

 males (two just emerged) and one female on grass and posts near 

 the sweet gale. I think this conclusively proves that the moth is 

 quite distinct from C. hrnmata, as that species must have been 

 quite over for a full month. I suggested that the warmth of the 

 room in which the pupae had been kept (there having been a fire 

 in it most days since last August) had delayed their appearance, 

 if they were C. hrnmata, as it was possible they had been waiting 

 for cold weather ; but he tells me he bred C. brumata in the same 

 room, and that they emerged on the 5th November. 



Dr. Staudinger gives only two species in the genus, so that it 

 must be new to Science. I therefore propose the name Cheima- 

 tohia myricaria. The following is a description of — 



Cheimatohia myricaria, mihi. 



Expanse of wings fifteen- sixteenths to one inch and one-eighth. 

 Fore wings brown, tending to purple, with several wavy darker 

 transverse lines, and a darker central band ; in some specimens 

 the ciliae are spotted with dark brown at the ends of the nervures. 

 No central spot. The nervure in the middle of the wing forms a 

 dark line where it passes through the dark band. Hind wings 

 pale, with darker ciliae. It is rougher looking than its nearest 

 ally, Cheimatohia hrnmata, and rather smaller. The diflerence 

 in colour between tlie two sjjecies is more striking on the under 

 side. The female has the rudimentary wings grey, shorter than 

 C. hrumata, and in some cases without the dark band ; its place 

 in others hidicated b}' a dark spot on each edge of the wing.
