the abdomen especially in the hindwings, but in var. callnnfe they 

 are directed towards the anal angle of both wings. I cling to this 

 as a real distinction, which can be readily seen, though I must 

 confess that there appear to be intermediate forms. It is asserted 

 that in L. querciis the antenna have 64 joints and in var. callima 

 84. This is not seen without a microscope, I offer no opinion upon 

 it. If it is true, it is a really valuable distinction. 



" Several other differences are suggested. I have found them all 

 indefinite. Though many are correct in the majority of cases. 

 Shortly, these are as follows : — 



" L. querciis, both males and females are paler in colour, show no 

 "white spot on the underside, have wing nervures of the same colour 

 as the transverse band, and no basal patch to forewings. 



Var. calluna, both males and females are darker in colour, 

 show a white spot on the underside, have wing nervures darker than 

 the transverse band, and have a basal patch to the forewings. 



"Even my own series show plenty of cases, where none of the 

 last-named distinctions hold good. I hope to hear many views 

 upon the distinction of the two forms." 



Mr. R. Adkm remarked on var. calhnm that he agreed that 

 there was evidence of two races running side by side just as had 

 been suggested in the case of Tephrosia biundulata and T. 

 crepuscularia. Possibly there was a species in the making. 



Mr. Brooks made some remarks upon the habits of Hyria 

 muricata (axiroraria) as observed by him at Wicken during his visit 

 in mid-June of this year and on other occasions. It was generally 

 stated that the species was obtainable in any numbers only at dawn, 

 which was believed to be its time of flight. He had found it very 

 common at mid-day during this period, and on the first day when 

 there was no wind and without disturbing the herbage, etc., it was 

 possible to take several with one sweep of the net. Ematurga 

 atomaria was flying at the same time, and both were about equally 

 common and easy to catch. There were, however, no females taken 

 by either himself or his companion. Two days later, when there 

 was considerable wind, he netted two specimens and commenced to 

 search for females by disturbing the growth beneath bushes from 

 whence he had observed males rise on the previous day, and was 

 successful in obtaining a good number of examples. The species 

 was apparently quite abundant there this year. 



Mr. Adkin said that the species was uncertain in its appearance 

 in the New Forest, and then generally in the evening and at dawn. 

 Other members had met with it in the day-time.
