100 THE ENTOMOLOGIST. 



common in one place. C. testata, rare last year. Scoparia ambigualis, 

 S. atomalis, very rare last year ; other seasons abundant. S. alpina, a 

 nice lot, but the forms not so good as those I obtained in 1879. 

 Herbula cespitalis, a few. Crambus pratellus, common. C. pascuellus, 

 C. perlellus, C. hortuelliis, rare last season. Sericoris littoralis, always 

 rare. S. lacunana, not common; a few each season. Mixodia schulz- 

 iana, two only ; some seasons in thousands. Cnephasia musculana, 

 common. SciapJiila colquhounana, fairly common. Bactra lanceolana, 

 common. Phoxopteryx unguicana, a few ; common some seasons. 

 Dicrorampha tanaceti, common in the larva state. Catoptria ulicetana, 

 common ; very small form. Symathis oxyacanthella, larva state only. 

 Eupoecilia thuliana, rare last season. Argyrolepia cnicana, common. 

 Blabophanes rusticella, a few. Plutella cruciferarum, two. Gelechia 

 plantaginella, fairly common. G. ericetella, rare last season. Endrosis 

 fenestrella, too common. . Glyphipteryx cladieUa, a few. — (McAbthxir). 



Of the majority of the species enumerated above there is little 

 now to say, as they have been fully dealt with in former papers 

 on the Lepidoptera of Shetland by Mr. J. Jenner Weir and the 

 late Mr. Howard Vaughan (Entom. xiii. pp. 249-251, 289—293, 

 plates 3 and 4 ; xvii. pp. 1 — 4, pi. 1). With regard to one or 

 two of them, however, I venture to make a few remarks. 



Hepialus humuli. — With one exception, all the males of this 

 species taken by Mr. McArthur on the cliffs in Unst, which face 

 the south-east and are drier than other parts of the island, were 

 more or less typical, and he informs me that he never remembers 

 to have taken a smoky or richly-marked specimen on the cliffs. 

 On the other hand, the majority of the specimens captured in 

 the boggy meadows and water- sodden " corn rigs " were of the 

 form known as var. hethlandica, Staudinger. By the way, 

 Newman's name thulensis (Entom. ii. 176) is earlier, and ought 

 perhaps to be adopted for this form. 



Crymodes exulis. — This was the best insect obtained in the 

 Shetlands last year. The specimens, between fifty and sixty in 

 number, exhibit considerable variation, and among them are 

 examples agreeing with typical exulis, whilst others are of the 

 groenlandica form. None of the specimens, however, were like the 

 Perthshire form assimilis ; neither do any of them agree with 

 any Iceland examples of the species that I have seen. 



The type of exulis, as described and figured by Lefebvre 

 (Ann. Soc. Ent. Fr. 1836, p. 392, pi. x. fig. 2), has the fore 

 wings variegated with grey and brown ; the central third of the 

 wing is reddish brown, limited by dentated black lines, which are 

 edged with yellowish grey; the stigmata are outlined in grey, 

 the orbicular placed obliquely, and the reniform is bordered out- 

 wardly with yellowish white ; submarginal line dentated, tawny, 

 and preceded by several cuneiform brownish marks. Fringes 

 reddish brown chequered with tawny. Hind wings tawny grey, 

 with yellowish white fringes. Under side of all the wings 

 yellowish sprinkled with grey, and with a brown arcuated line
