NOTES ON THE FtTMEIDS. 125 



joints, intermediella, 19-20, though I am prepared to grant that this may be so, 

 and that the variations in size are such as to make them overlap in this feature. 

 We found, however, in crassiorella a considerable variation ii:i the number of 

 antennal joints, which it seemed impossible to use as a means of dividing that 

 species. In nitidella and intermediella the antennae present indications of being in 

 process of altering the number of joints in the manner I have described in speaking 

 of the antenna (anterior tibia, pi. iv., fig. 44). 



5. var. bowerella. — This is a very definite form in one special respect. I have 

 met with it only in a certain number of specimens bred by Mr. B. A. Bower from 

 Kentish localities. Its general facies is much that of nitidella, if anything rather 

 smaller, 11mm. in expanse, spurs -77. The difference is in the antenna ; instead 

 of having 18 joints it has only 16 or 17. The antennal pectinations are the same 

 length as in so many other species, viz., -SOmm., but they are relatively to the 

 antennal joints very short, i.e., the antennal joints are long, viz., •240mm., a very 

 constant group of nitidella having them only ■202mm. in length, another specimen 

 •210mm., and the longest I have found in any other specimen was -227 in a large 

 intermediella (anterior tibia, pi. iv., fig. 48). 



Fumea scotica (?var. e). — This is a very large form, and of very robust 

 appearance, so that it is very difficult to resist the conclusion that it 

 is a distinct species. It agrees with F. casta in having 19-20 antennal 

 joints and a spur length of '18, but in size it rivals M. crassiorella, being 

 13mm. -15mm., and in apparent solidity and robustness it exceeds it. 

 This form comes from Eannoch and Sutherlandshire. One cannot 

 avoid wondering here if this is not the same as norvegica, Heyl., a 

 Norwegian species which Dr. Heylaerts finds to be identical with a 

 south French form. Dr. Heylaerts is, however, very definite that not 

 only the French form, but the Norwegian one also, possesses the 

 " cellula intrusa." This, of course, places nori-egica in the reticulatella 

 group and widely apart from the specimens with which Ave are here 

 dealing (anterior tibia, pi. iv., figs. 43, 45). 



Fumea [lernianica, n. sp. — There remains the species Avith spurs 

 of -84 to -86. This I propose to name F. (jcrmanica, as the speci- 

 mens were sent me by Herr VoelschoAV, some as intermediella, some as 

 ajfinis. They agree, however, perfectly, and are all one species. It 

 may be that this is generally known in Germany as affinis. It is very 

 different, hoAvever, from the M. affinis sent me by Staudinger, and 

 described by Hofmann, Avhich I have already dealt Avith as closely 

 allied to, if distinct from, M. crassiorella. We may describe it as 

 follows : 



Fumea geriiianica, n. sp., does not appear to be distinguishable in 

 general appearance from F. casta var. nitidella, its expanse is 12mm., 

 it has 19-20 joints to the antennse, and a length of tibial spur AA'hich is 

 far in excess of any other species I have examined, and obvious to 

 the unassisted eye AA'hen compared Avith F. casta, viz., -84 to -86. 

 Other intermediella sent me by Herr VoelschoAV are referable to F. 

 casta (anterior tibia, pi. iv., fig. 49). 



For the opportunity of making this examination of the Fumeid 

 species I am indebted to a number of English entomologists, who have 

 entrusted me Avith many specimens belonging to the forms and varieties 

 I have noted. Among them I may mention Messrs. A. Bacot, E. E. 

 Bankes, C. G. Barrett, B. A. Bower, Briggs, the Kev. C. E. N. 

 BurroAvs, Messrs. J. A. Clark, C. W. Dale, W. H. B. Fletcher, A. H. 

 Hamm, Dr. Mason, Messrs. Montgomery, L. B. Prout, N. Eichardson, 

 S. Stevens, J. W. Tutt, F. G. Whittle, to all of whom my best thanks 

 are due.
