230 THE entomologist's record. 



much more common here than at Wicken, and the number of yellow 

 reeds I saw scattered all over the Fen gave evidence of the work of 

 the larvae in the roots below. The first species I met in the " Fen " 

 were Crambtis tristelliis with a few C. selasel/ns, Rivula sericealis, and 

 Leioptilus microdadyla. A plant of Verbascutn was eaten completely, 

 and large quantities of " frass " were on and about it ; but I could 

 find no larvae. Pieris ?iapi occurred abundantly everywhere in the 

 " Fen," and passing through a belt of trees Rivula sericealis began to 

 occur in considerable numbers. In the course of the day I took some 

 60 or 70 specimens of it, most of which were in fine condition. This 

 species I have taken in many marshy localities, but I have never seen 

 it really abundant before. The long grass and sedge were mixed with 

 Vicia cracca, and from this several Toxocampa pastinmn were disturbed. 

 Some of these were in fair condition, much better than others I had 

 observed a fortnight earlier in North Kent. The paths crossing the 

 Fen appear to have been made up, at no very remote period, 

 of Cretaceous rocks (gault, etc.), and on these, many species of 

 the "chalk" flora were established, and appeared sirange in the 

 " Fen " ; and here such species as Pyrausta purpi/ralis, Phytomet7-a 

 cenea, Lyccena icarus and Polyommatus phlceas were flying merrily in 

 the sunshine. Strangest to me, though, was the sight of numbers 

 of Epinephele hyperanthus flying freely all over the Fen. I turned 

 up one Bankia argefitula, the first I had seen alive. It was in 

 good condition, probably the offspring of an early ? of the 

 same summer. A made road, overgrown with flowers, produced, 

 besides lots of Rivula sericealis, — T. pastinuin, Stre?iia clathrata, 

 Afelanippe subtristata (second brood), Stigmonota orobaiia, Catoptria 

 scopohaJia, Nematois schiffermillerellus, Alimaseoptilus bipuuctidactyla, 

 Sciaphila chrysafitheniana, and in a field hard by, Crambus selasellus 

 (without C. tristellus) and Catoptria scopoliana were fairly abundant ; 

 and here also I took an odd specimen of Semasia rufillana. Besides 

 these, I noticed several Acidalia scutulata, also Eubolia mensuraria, and 

 other species equally common. I left at 6 o'clock and was well 

 satisfied (considering that I did not stay to take a single evening-flying 

 insect^ with some 160 specimens I had captured, and many observa- 

 tions made ; and I am sure the Fen, which can be easily worked 

 from Fordham, where there is plenty of accommodation, would give an 

 excellent result, especially to any one who could get there during the 

 latter part of June and the early part of July. I may add that Mr. 

 Houghton took a fine lot of Macroglossa bombyliformis larvce on Scabiosa 

 there this season. He found them when small on the undersides of 

 the leaves during June, the plants attacked showing conspicuous 

 evidences of the work of the larvre. — J. W. Tutt. August, 1892. 



Teivkesbury. — This has been, in this locality, one of the best seasons 

 we have had for Geometers for a long time. Sugar has varied much. 

 With the dry moonlight nights there has been very little ; then when 

 we have had a warm dull night, things have been fairly plentiful. One 

 thmg has struck me, how on some nights certain trees attracted freely, 

 and then on another night the same trees produced nothing, whilst the 

 trees barren before produced the moths. On the light nights, a tree 

 over a pond proved attractive, but Saturday night last was the best 

 night we have had ; the barometer was falling, night rather dull,
