only difference being in the form of the fore-wings, which may be a variation from 

 local reasons), that I should place it also as a form. If any one takes vorticella 

 freely, and would kindly allow me to inspect a series, I should thank him much and 

 return them uninjured. 



Nepticula betulicola. — Last year, when breeding Nepticula hetulicola, I thought 

 that another species was emerging with them from similar larvae, but on a more 

 extended trial this year, I found that the two sexes differ considerably, and thus my 

 doubts were solved. Betulicola males are rather smaller and browner ; frequently 

 the fascia does not extend quite to the costa, and the head is fuscous with white eye 

 caps. Hetulicola females are purplish from the base to the fascia, which extends 

 quite to the costa, and the head is yellow. This insect varies in intensity of colour 

 with the tempei'ature and climatic conditions of the season. Some years ago in a 

 hot summer I bred some as brilliant as alnetella. 



Nepticula regiella bred.—l had last autumn collected considerable quantities 

 of yellow larvae blotching whitethorn, in order to find out the larva of Nepticula 

 ignobilella, which I am at present unable to separate from that of gratiosella. The 

 result was that I bred this May plenty of gratiosella, none of ignohilella, and one 

 regiella, in the room. As I had larvae from Witherslack and Preston (viz. : from 

 limestone and sandstone), I am unable to determine the district from which it came, 

 but hope to do so this year. I have previously bred ignobilella from one of the 

 localities, and it is very curious that none turned up this year. The Nepticulce that 

 frequent hawthoi'n on limestone appear to be pygmceella, oxyacanthella, and atri- 

 collis. Those on sandstone pygmmella, oxyacanthella, gratiosella, and ignobilella. 



Species neio to the Witherslack list. — I took a single specimen of Retinia 

 duplana flying among fir trees this year; it is a very distinct species, and has only, 

 I believe, been before taken in Scotland in very small numbers. 



Depressaria Tiypericella has been bred this year from shoots of Hypericum, by 

 both Mr. Shuttleworth and Mr. Murray. It had not previously been noticed in the 

 district. 



Some time ago Mr. Sang took a specimen of (Ecophora minutella, and this year 

 I was fortunate in doing the same. It was flying, near dusk, aci'oss a road near 

 farm buildings. 



In August I first found larvse of ^s^eAwa terminella mining in the leaves of 

 Circasa lutetiana in dark places in the woods. 



In September, last year, I found and recognised mines of Nepticula prunetorum 

 in sloe. I had before seen this larva but had stupidly mistaken it for Nepticula 

 plagicolella. I now see that the latter is yellow and makes a clear whitish blotch 

 preceded by a slender gallery : the former is green and its mine is coiled like a watch 

 spring, afterwards extending round the edge of the leaf. The "frass" fills up the 

 gallery and makes it light brown. The imagos emerged very freely in June. 



About August, I found mines, which appeared strange to me, in wild strawberry, 

 these produced in June Nepticula arcuosella. The other mines found in wild 

 strawberry produced Nepticula aurella, at least, I cannot separate the two insects 

 at present. 



Amongst alder bushes in a swamp, in August, I came upon reddish mines
