white, which bound the middle area, are likewise suffused with 

 clear brownish-gray, thus they are not so distinct, while the middle 

 spot is smaller and more like a line ; and the broad network, 

 which in our venosata is very conspicuous on the front margin, is 

 much finer and less dark in the Shetland form ; so that, on the 

 whole, a greater uniformity in markings and colour is brought 

 about. This form is figured in the Entomologist 1880, plate 4,. 

 fig. 7. It flies in June.

I received 6 specimens of this curious form, which were all 

 alike. Dr. Staudinger, to whom I sent a pair, writes, " A form of 

 Eupithecia new to me, perhaps only a dark nanata" This form 

 certainly comes nearest to the nanata aberr. obscurata Stgr. ; but 

 it differs from this in so many important points, that it cannot be 

 united with it. The insect is larger, stronger, and somewhat 

 broader-winged than nanata ; the fringes are very long, especially 

 at the inner angles of the wings ; the colouring is a deep-brown 

 gray, with a somewhat reddish tinge. The wing-scales are coarser 

 and the whole marking more faded ; so that the white cross-lines 

 do not stand out so clearly. The wavy line is very distinct, and 

 has, as in Nanata in cell 1, b., a distinct, white, wider part ; on the 

 other hand, the white oblique line at the point of the wings is 

 wanting, as in hyperboreata Stgr. The bands, which enclose the 

 middle area, are very marked and run straighter, and the outer 

 one does not meet the margin so abruptly. In my opinion, this 

 Shetland form deserves a special name. Whether it should be re- 

 garded as a peculiar species, or should be referred to nanata as a 

 variety, I do not dare to decide. It flies in June. 



44. Scoparia Ambigualis Tr. Frey Alp. ; Stdfs. SiL Mont. ; 

 H. Here. Mont. 



Ordinary Form. June and July. 



45. Scoparia Alpina Stt. 



Figured in the Entomologist 1880, plate 4, figs. 1 and 2. It 

 flies in June. 



46. Scoparia Orataegella Hb. var. ; Stdfs. Sil. Mont. 



A small dark specimen, determined by Dr. Staudinger as be- 

 longing to this species. Probably caught along with ambigualis, 

 as I received the specimen under this name.
