" A POSER," STAINTON. 247 



There is at least one example of this species (labelled Coniopteii/.r 

 hi/aliniis, Steph.) in the Daleian collection. 



5. Coniopten/.r tineifonnis, Curtis. 



1834, JJrif. Ent., pit. 528; 1886, Steph., ///., x., 116. 



Not uncommon in summer, especially in fir trees (McLachlan). 



Probably a widely distributed insect. Quite common on oak and 

 sallow in the Cleveland district (J. W. H. Harrison) ; on oak, Gibside, 

 county Durham (R.S.B.). 



A large number of the examples in the Daleian collection fall into 

 Cnniopteri/.r, spp., but I am not able to deal with the bulk of them. 



6. Si'hiidali^ ali'iimdifoDiiis, Steph. 



1836, Steph., III., x., 116. 



Probably equally common witk the last {C. tineiforwh), but I 

 cannot say that I have personally noticed it (McLachlan). 



Apparently rare. The following are recent northern records : — 

 Cleveland district, Yorkshire, one exanaple from honeysuckle (J. W. H. 

 Harrison) ; Felton, Northumberland, one from oak, 1915. (R.S.B.) 



The only two examples in the Daleian collection that I can identify 

 as this species with any degree of certainty are labelled (and have been 

 wrongly identified as) (\ parvnliis, Vill., —tineiformis. Other examples 

 standing under that name are true Conioptery.v, spp. 



7. Semidalis ciirtisiana, Enderlein. 



1906, Zonl. Ja/nh., xxiii., Abt. f. Syst., p. 212, figs. 18, 62. 



Recognised chiefly by the position of cross-veins (nervules) in both 

 fore- and hindwings, and the relative lengths of the joints of the hind 

 tarsus. 



There are two undoubted examples in the Daleian collection 

 labelled " Conioptenj.r aleurodiforwiii, Steph.," 124 67 and 125/67.

 {Continued from page 199). 



I have now made an examination of the series of tni.r-liiniiiera in 

 the British Museum. There is first a set of the luninera, British, from 

 the Leech collection. They are all of the well-known form only 

 varying within the usual limits, orbicular and claviforui staring in 

 both males and females, reniform well marked, the usual soft grey 

 surface in the males and the delicate surface of the darker females, 

 hindwings strongly pearly in the males, etc. Next follows a series of 

 thirty-six specimen of what is called tntr. It is a series made up 

 from various sources and is presumably a very good exponent of what 

 many well-known authorities and collectors have recognised as tru.r 

 within the last fifty years. There are six from the Zeller collection, 

 six from the Frey collection, and fourteen from the Leech collection 

 including two of Staudinger's and one of Gerhard's. 



The first impression, which becomes still more dominant on closer 

 examination, is that the series called tru.r is a very distinct species 

 from the linu'r/era of Britain. It is a bigger, bolder species and 

 practically every character contrasts strongly with the delicate general
