176 DORSET LEPIDOPTBRA. 



lighter towards the anal plate, which resembles in colour the warts 

 in its neighbourhood. An inconspicuous brownish hair springs 

 from a minute black spot in the centre of each wart ; legs, dark 

 greyish brown ; edges of spiracles intensely black and solid looking 

 under a microscope, but hardly visible to the naked eye ; booklets 

 of claspers nearly black, claspers of the neighbouring ground colour.

Mrs. Richardson was fortunate in taking on July 10th the sixth 

 specimen of Epischnia bankesiella, which seems to occur regularly 

 at Portland, though we have never taken more than two in a 

 season viz., two in 1887, one in 1888, two in 1890, aud one in 

 1891. It does not appear to have yet been found in any other 

 part of the world. 



Of Tinea subtilella, which has not yet been recorded from any 

 other part of the British Isles, six specimens were this year taken 

 by ourselves and two by the Rev. C. R. Digby when at Portland 

 with me in August, making, with last year's captures, 16 specimens 

 in all. Had the weather been more propitious I think it probable 

 that this insect would have been taken in greater numbers. The 

 same remark applies to other species which the very bad weather 

 has made it difficult to obtain. 



Agrotis pyrophila was not seen at Portland at all this year, 

 though in 1890 it was taken more abundantly than has been the 

 case during my collecting there, which extends now over six 

 seasons. This has the character of being a scarce and uncertain 

 species in its appearance, and the numbers taken by me in the 

 years 1887-91 fully bear this out. They are roughly 1, 15, 1, 25, 

 for the five years. 



Two more moths I have to record new to the county ; one is 

 Psecadia decemguttella, of which I found the very pretty black, blue, 

 and yellow larva feeding on Lithospermum in a small copse near 

 Weymouth last September. 



Of the other, Stepliensia brunnichella, after considerable search I 

 found in the latter part of September, some pupa cases and mines of 

 the larvse which had fed during the summer in the leaves of
