years ago. I must confess I am somewhat puzzled to know 

 how a moth can prove itself to be another species, after a 

 lapse of several years, by laying nine eggs. However, as 

 regards ray own six specimens I must refer him to his very 

 intimate friend Mr. John Warrington, late of Tranmere Hall, 

 Cheshire, who not only saw me capture Compta (not var. of 

 Conspersa), but captured one himself. As regards others not 

 being able to find it, I may say Barrettii is not a Manx 

 species. 1 know Port Jack well, and have spent night after 

 night searching for D. cajsia, but never took Barrettii, 

 although I have caught sixteen specimens in a night on the 

 coast of Ireland. Again, with Sesia Philanthiformis, Mr. 

 Gregson tells us it is common at Howth, but I have failed to 

 find it, although I have worked the Hill of Howth yard by 

 yard; also the adjacent islands, viz., Ireland's Eye and 

 Lambay. Perhaps I may be more successful another 

 season. — E. G. Meek ; 56, Brompton Road, S. W., October

Larv(B of Xanthia gilvago and X. ferruginea. — On the 

 4th of last June I beat some larvae from the bunches of green 

 seeds on a wych-elm : they fed only on the seeds, and about 

 the middle of June went down in the soil. I supposed them 

 to be Xanthia gilvago, as they answered almost exactly to 

 your description, but to my disappointment Xanthia ferruginea 

 emerged from the pupae. In your 'British Moths' you do not 

 mention elm as the food of Ferruginea, but of Gilvago ; and 

 Mr. Greene also says Gilvago feeds on the seeds of the wych- 

 elm. I should be glad if you could tell me how to distinguish 

 between the larvae, for two or three years ago I bred Gilvago 

 from larvae off the same tree, and I cannot remember any 

 difference in their appearance. — Anne Steele Perkins; Ash-

On the Antennoe of Erislalis tenax. — The terminal joint 

 on each antenna is flat on the inner surface and gibbous on 

 the outer one, and both surfaces are thickly and evenly 

 covered with very minute hairs, just such as terminate the 

 dorsal surface of the antenna? of P. Capitis; but the second 

 joints of E. tenax are smooth and polished, with only a few
