Later at night we devoted ourselves to working for Lithosice at the 

 alder carr, griseola and stramineola being then common, but muscerda 

 rather scarce. Stray specimens of Celcena Haworthii and Hydrelia 

 unca also turned up. 



On a second visit on August 14th, many of the same species were 

 out ; the Lithosice not quite over ; of muscerda, even three specimens 

 occurred to Mr. De Grey's superior luck (I did not see one) ; and 

 Eupithecia tenuiata had become quite common among the sallows, 

 where also Depressuria conterminella, Yeatiana, &c, were not scarce. 



The two species of Hypenodes were occasionally to be disturbed 

 among the long grass, and usually had the wit to fly across the 

 water to inaccessible places, and Peronea Shepherdana and aspersana 

 turned out from among Spiraea ulmaria. Elachista cernssella and 

 paludum also occurred rarely among the herbage, and I had the good 

 fortune to turn out one specimen of Gdecliia muscosella, the novelty 

 discovered a few weeks before by Mr. De Grey, at "Wicken fen. 



A stramineola $ , fished out of a drain on this occasion, obligingly 

 laid a batch of eggs, which, under the fostering care of Mr. Hellins, 

 will, I hope, help to solve the vexed question of the distinctness of this 

 species from griseola, especially as Mr. De Grey had, I believe, the 

 good fortune to secure eggs of both species (or varieties). 



One curious and rather unexpected morsel of evidence has occurred 

 to me. Among the specimens of stramineola taken, were several varieties 

 having more or less of the ground colour of griseola in irregular patches, 

 and forming apparently regular connecting links, but these specimens 

 have all faded so much that already they hardly differ from normal 

 stramineola, while the typical griseola by their side are just as when 

 taken. 



I omitted to mention, that, on our first trip, a rough piece of 

 ground by the road side attracted our attention, and, alighting, we 

 proceeded to investigate it. Among the short heath Mr. De Grey very 

 soon secured Sophronia parenthesella, and we found Pterophorus teucrii 

 common among Teucrium scorodonia. 



On a second visit a few days after, I found this plume in great 

 abundance, though worn, and secured a few specimens of Ebulea 

 verbascalis and Sovhronia parenthesella. A thunder storm was im- 

 pending ; and the plumes, apparently delighted with the prospect, were 

 dancing over the Teucrium like Tipulcs.
