drying up, until the pits are filled by the autumnal rains. It 

 has hitherto been a scarce species. 



Zimnephilus stigma, Curtis. This appears to be a very 

 local species; Mr. Wormald found it abundantly at Ruislip 

 Keservoir, Middlesex, and I also took it at the same place. 

 It is excessively variable : some examples have no markings 

 except the dark pterostigma, and thus resemble Curtis's and 

 Stephens's types (some of these even have no pterostigma, 

 but I have seen no recent specimens without it) ; in others 

 the fore-wings are almost entirely dark brown, owing to the 

 numerous dark spots becoming confluent, the pale fenestrated 

 spot and anastomosal space then appearing very conspicuous, 

 but the majority have the wings thickly speckled with brown, 

 darkest towards the inner margin. This form is the typical 

 6r. sti(jviaticus, Kolenati, and probably identical with 

 L. fulva and impura, Rarabur.

Limnephilus hirsulus, Pict. (nee Kolenati). Phryganea 

 hirsuta, Pictet, Recherch. p. 159, 29, pi. 11, fig. 10. This 

 species has not been hitherto definitively recorded as occurring 

 in this country. Dr. Hagen compared a specimen of No. 2, 

 Ent. Annual, 1862, p. 28, with Pictet's type, and found them 

 identical. 



Stenopliylax. My paper on this genus is published in 

 Part 3, Vol. I. of the Third Series of the Transactions of 

 the Entomological Society. The relationship of this genus 

 to Anaholia is very close ; the latter seems to differ chiefly in 

 the peculiar form of the anal appendages. 



Apaiania vestita, Kolenati. Mr. Piffard gave me several 

 specimens taken by him in the beginning of May near 

 Windermere : the app. intermediate are long, slightly curved, 

 needle-shaped ; the app. inf. very long, biarticulate ; the first
