210 THE ENTOMOLOGIST. 



E. hybiidellana, Hb. — Local and scarce ; more abundant in the 

 larva state. I have taken a very few not far from Pitsea, and found 

 the little pinkish larva in abundance, feeding in the seed-heads of 

 Helmmthia echioides, but I found it very difficult to breed. 



E. anr/ustana, Hb. — The small pale form sometimes swarming in 

 early August over Calluna vulgaris at Loughton, Warley, Tiptree, &c. 

 The much more handsome and earlier form (which feeds upon the 

 seed of Plantago lanceolata, and, I believe, other plants) is much less 

 common. Thames Haven, railway banks near Komford, also rough 

 fields near Upminster. I was at one time inclined to think we had 

 two species mixed up here. 



E. vectisana, Westw. — Very common in the salt marshes amongst 

 Triglochin maridmum, its food-plant. Mr. Machin met with a specimen 

 on Hackney Marshes, where it had probably fed on the allied T. ixilustre. 



E. afjinitana, Dougl. — Common in every salting where Aster tri- 

 poliiim grows. I have found the pupa in the spring in the upper part 

 of the previous season's flower-stalks. 



E. ndana, Gn. — Seldom seen on the wing, but the larva may be 

 found in most places in the stems of Alisma plantago, pupating therein. 

 The insects last over a considerable time ; this summer, for instance, 

 I bred one on June 11th, and the next specimen came out on July 12th ! 



E. notidana, Zell. — I have never bred this insect or met with the 

 imago in Essex ; but in 1886 I found, near Brentwood, in the early 

 autumn, several larvae in stems of Mentha aquatica, which were no 

 doubt this species, but I failed to rear any of them. 



E. rupicola, Curt. — Scarce and local. I have found the larva on 

 the banks of the Chelmer, near Chelmsford, in the old prostrate stems 

 of Eupatorium cannahinum, but this plant is by no means common in 

 the districts where I have collected. 



E. rnseana, Haw. — May generally, but not always, be found in the 

 larval state in heads of the common teazel. Harold Wood, Benfleet, 

 Pitsea, and Cauvey Island. From the last named locality I bred the 

 largest and most beautifully coloured specimens I have seen. 



E. ciliella, Hb. — Only met with at Ingatestone, where a few larvae 

 were found feeding in the seeds of the common cowslip. Primula veris. 



E. iinplicitana, H. S. — Not rare ; may be found among such plants 

 as Anthemis cotula, Matricaria inodora and chamomilla, in the seed of 

 which tlie larva feeds, often, but not always, pupating in the stems. 

 I have also bred it freely from flowers or seeds of golden rod from Kent. 



E. erigerana, Wlsm. — Very local in South Essex. I have only met 

 with it once on a piece of waste ground near Harold Wood. I found 

 it very abundantly near here (Croydon), and also bred it from flower- 

 heads of Erigeron acre a few weeks ago (August, 1901). 



Xanthosetia zoegana, L. — Not common, but very widely distributed. 

 I have taken the very striking xsn-.ferriigana, Haw., near Stratford, on 

 Ley ton Marshes. 



X. hamana, L. — Very common and variable amongst the various 

 species of thistle in every locality I have worked. The larva is said 

 to feed on thistles, but I have never met with it. 



Chrosis tesserana, Tr. — Common on rough, dry, waste grounds, and 

 in great variety, some of which are very beautiful, others nearly or 

 quite unicolorous. I once bred nearly forty from larvae obtained the
