316 THE entomologist's record. 



/3*. Much as English L. querci'is, with the yellowish-grey hairs on the back 

 slightly lighter. Subdorsal hairs fairly long, white. 



The first spun up on December 12th, 1897, all three were spun by 

 January 10th, 1898. A male emerged on April 20th, 1898. One 

 pupa got mixed with others and one remains apparently dead. 



This specimen is similar to my L. callunae, but the L. hieridionalin 

 strain has modified it in the following way. The epaulette is absent, 

 the colour a little redder (both ground colour and band) the space 

 beyond band little powdered with yellow, and the nervures less 

 conspicuous, so that, though the general facies, owing to the large 

 spot and general colour, is that of L. callunae, yet the honours are fairly 

 divided in the case of the imago if not slightly in favour of L. iiieri- 

 (lionalis. In the larva the contrary is the case. 



(2) L. viburni^ x L. qiwrcih (Dorset) J ( = 3<? x5 ?). — Mr. Bacot 

 obtained larvfe from ova (laid July 10th, 1897), but no imagines. 



(3) L. vibumi^xL. callunae 2 { = 2^ x8 2)- — The ? L. cal- 

 lunae was placed by Mr. Bacot with a ,3^ No 6{ = niendinnalis xviburni) 

 but did not lay, it was then paired as above and began to lay at once. 

 From these ova (laid July 20th, 1897) larvffi emerged of which none 

 survived. My only note referring to them is that they were " very 

 brown." 



(4) L. quercm (Dorset) <? x meridionalis ^ (^ = 5 ^ x 2$). — 

 Paired by Mr. Bacot (J. July 28th, 1897), Mr. Bacot reared 3 <? and 4 ? 

 imagines. My larvae, described when three inches long were similar to 

 "pure Dorset," the spiracles and dashes very white ; the face dull black 

 (as in English) or somewhat rusty (L. mcridionalis has a rusty-red 

 face). My imagines 4 J s and 8 $ s emerged April 20th- June 4th, 1898. 

 They are handsome moths. The males, which are larger than their 

 father (a very undersized specimen), are considerably browner (less 

 red) in colour than L. nieridionalis. The band is also more diflused 

 externally. Except that the band is less sharply curved than in the 

 father, they may be considered to follow his type almost exactly in 

 colour and markings. The females follow their mother except in two 

 points. They have the usual more variegated look of L. nieridionalis 



2 with the base of hindwings brown (in one specimen almost as 

 brown as the male parent) in fact they are several of them more 

 contrasted in colouring than the ? parent which was of the fairly 

 uniform reddish-brown type with lines and dots not prominent. 

 They range in colour from the ochre of the Dorset 5 type to the 

 one before mentioned, but they are all yellow in general effect, and 

 not reddish like the $ parent. The nervures are distinctly lighter than 

 the wing, and thus become in the darker ones conspicuous. This is 

 derived from the father's family as the mother has the nervures 

 practically unic^lorous. These females may, therefore, be considered 

 good intermediate forms. A peculiarity of this hybrid, which was 

 not noticed in any of the others, was that the ova, produced in the 

 only cases in which pairing was attempted, were sterile. These were 

 the following : — 



(1) L. {qnerciiti (Dorset) x nieridionalis) $ xL. {qttercns (Dorset) x 

 meridionalis) $ (= ^ (5 x 2) x ? (5 x 2)). 



*a and /3 with conspicuous white spiracles and dashes ; a is perhaps like typical 

 L. callunae. I do not know the larva. Mr. Bacot has since contirmed this opinion.
