LEPIDOPTERA OF ASSYNT DISTRICT OF SUTHERLANDSHIRE. 55 



Agrotis stiigula. — Common amongst heather at dusk. 

 Noctua augur. — At sugar. 



N. brminea. — Common at sugar ; a beautiful reddish form, == 

 -var. rufa, Tutt.. 



N. c-nigrum. — At Lochinver ; Mr. Whittle. 

 N. primulae, Esp., = /estiva, Hb.— Common at sugar. The 

 specimens were reddish-brown unicolorous forms showing little 

 variation. 



N. rubi. — Common at sugar. . 



N. xanthographa. — One dark example at sugar, July 14th — 

 a very early date. 



N. plecta. — Common at sugar ; the examples have the costal 

 streak darker than is the case in southern specimens. 



Triphaena comes. — Two examples only at sugar, one a bright 

 pale red = var. rufescens, Tutt, the other = var. ochrea, Hum. 



T. pronuba. — Common at sugar. Various forms ; particulars 

 not noted. 



Mamestra pisi. — One example only at sugar, = var. pallida, 

 Tutt. 



Eumichtis adusta. — At sugar ; = the type form. 

 Bombycia viminalis. — Larvae not uncommon on sallows at 

 Lochinver ; the resultant imagines are very beautiful and highly 

 variegated forms perhaps near intermedia, Tutt, but I have never 

 seen similar specimens. 



Hyppa rectilinea. — Scarce at sugar ; very beautiful dark 

 examples of var. virgata, Tutt. 



Miana fasciuncula. — Scarce at sugar ; the red form = type, 

 and var. cana, Stgr., and intermediates. 



Xylophasia rurea. — This, the most interesting Noctua met 

 with, was common at sugar ; a very variable series was taken, 

 consisting of the greyish-white type, and the following aberra- 

 tions : ochrea, Tutt ; Jlavo-rufa, Tutt ; alopecurus, Esp. ; and 

 nigro-rubida, Tutt. Of this form Tutt writes (' British Noct. 

 and their Varieties,' vol. i, p. 81) : "I have only seen this 

 variety from the Island of Lewis." 



X. lithoxylea. — One example at rest on a post in the daytime, 

 Lochinver. 



X. monoglypha. — This variable species was abundant at sugar, 

 but the forms were not so dark on the whole as one expects to be 

 the case in examples from Northern Scotland. I saw, perhaps, 

 half a dozen black specimens, and the great bulk were the light 

 southern form = the type ; there was a considerable number of 

 ab. brunnea, Tutt. I brought away two examples which do not 

 agree with anything described by Tutt, or that I have seen 

 elsewhere. They are very handsome, extremely dark variegated 

 forms, but the ground-colour is a rich intensely dark brown. 

 Very similar to that of Crymodes exulis, var. assimilis, but even 

 more intense and brilliant than obtains in that form.
