122 THE entomologist's record. 



conspicuous species of eleven families beautifully mounted for 

 inspection. The exhibit of the latter was a most beautiful collection 

 of small cases illustrating the life-histories of many gall-flies and insects 

 with similar habits. Aphelotrix lucida, a species new to Britain, 

 feeding on poplar, was noted ; this might perhaps turn out to be 

 Geculomyia 'persicariae. Of botany and conchology, Messrs. S. J. Bell, 

 F. J. Hanbury and F. B. Jennings supplied material. Mr. Jennings' 

 series of Helix nemoralis var. libellnla, from the Lea Valley, showed the 

 band variation completely. Of Eeptilia, we noted a fine specimen of 

 Alligator sderops shown by Mr. Sauze. Flint implements were shown 

 by Mr. H. A. Fuller, while etchings, photographs, &c., were also on 

 view, and lent by several members. The etchings of British butter- 

 flies shown by Mr. H. H. May were excellent. Last, but by no means 

 least, a number of microscopes were lent by Messrs. A. Bacot, J. 

 Burton, S. Edwards, E. W. Lane, H. H. May, C. Nicholson and J. A. 

 Simes, and these gentlemen untiringly saw that the visitors should 

 have the full benefit of their instruments.

The remaining species all agree with M. crassiorella in wanting the 

 " cellula intrusa." They may be divided into three groups, according 

 to the length of the anterior tibial spurs. A group with spurs sub- 

 stantially the same in length as in 21. crassiorella, or slightly longer 

 •70--73, containing affinis, suhjiacella, and two or, possibly three 

 unnamed species. A second group consisting of the various forms 

 that we may include as one species under the name of F. casta, with 

 four or five varieties, not difficult to recognise, but far from easy to 

 separate conclusively from each other. These all have spurs of length 

 •77- "SI. A third group, with spurs -84- 'BG, containing only one 

 species, germanica. 



The crassiorella group possesses certain species that may or may 

 not be distinct from crassiorella itself : 



(1) M. affinis. — According to Hofmann this possesses five antennal 

 joints more than F. casta [nitidella), therefore 23 or 24 joints. Hence 

 a specimen I have from Staudinger is probably truly that species, 

 agreeing otherwise with the description. It has a spur very slightly 

 longer than M. crassiorella, viz., -70, probably really the same, 24 

 antennal joints, and precisely the same colouring and wing form as 

 M. crassiorella; it is slightly smaller, 12mm. -13mm., and seems to be 

 more densely scaled, the basal half of the cilia of hind margin of fore- 

 wing looking especially dense. The greater measured length of the 

 antennal pectinations may or may not be a good character. I am not 

 prepared from this one specimen to say positively it is only a var. of 

 M. crassiorella, I should be even less disposed to assert it to be a good 

 species or more than a local race of M. crassiorella (anterior tibia, pi. 

 iv., fig. 35). 



(2) ill. mitfordella. — We have here certainly a species distinct from 

 any other named form I can find any account of. The specimens it is
