ENTOMOLOGY IN OCTOBER. 15 



hatch, judging by the appearance of the bush on which they had 

 been feeding, several Eriocampa ovata, many broods of Hemichroa 

 rvfay ranging from freshly-hatched to nearly full-fed specimens, 

 and three unknown species (probably Nematiis) represented a 

 profitable day's work. Another treasure trove was a black larva 

 on Hsh, a strictly nocturnal feeder, burrowing just under the 

 surface of the earth by day. 



The following week, on my return to Lyndhurst, I was agree- 

 ably surprised to find a good hatch of Croesus varus, and another 

 of Hemichroa rufa, both of which I had vainly sought for four 

 years. It is very strange how one may go over the same piece of 

 ground year after year, and yet find new species. 



Altogether the autumn season has quite made up for the 

 disappointments of spring. The result of both together, as 

 regards new species taken in or near Lyndhurst, may be sum- 

 marised as follows : — April to August : Cladius padi. August 

 to October: Croesus varus, Hemichroa rufa, Nematus tibialis, 

 Poecilosoma luteolum ; also four unknown kinds. 



In or near Stafford, last week of August and first of September : 

 Nematus compressicornis and N. curtispina, Cladius rujipes (one 

 specimen), Croesus varus, Camponiscus luridiventris, Eriocampa 

 ovata, Hemichroa rufa, Emphytus ci^ictus, Taxonus equiseti, and 

 four unknown kinds. 



The following larvae, usually common round Lyndhurst, 

 were either entirely lacking, or much scarcer than usual : Nematus 

 abdominalis, N. ruficapillis, N. hetidce and N. lacteus ; Eriocampa 

 annulipes and E. varipes, Hylotoma gracilicornis, H. iistulata, and 

 H. rosea; Poecilosoma pulveratum, Dolerus ncematodis, Tenthre- 

 dopsis microcephala, and Tenthredo viridis. 



As common as usual were the following larvae : Nematus 

 pavidus, Croesus septentrionalis, and C latipes, Strongylog aster 

 cirigulatus, and Emphytus serotinus. T may mention here that 

 during five years in which I have endeavoured to rear the last 

 named larva, I have been unsuccessful in every instance. I have 

 tried young and full-fed larv£e, have given abundance of growing 

 food, and earth in which to pupate. The result has always been 

 the same. They are apparently healthy, feed well, go down with 

 alacrity, and never come up again. I have tried keeping the earth 

 moist and dry ; have given it them shallow and deep. Nothing is 

 of any use. I should be very glad to hear if these larvse are com- 

 monly considered delicate, and what is the best treatment for them. 

 Lyndhurst.
