Bisulcia, Chpmn., ligustri, Fab. 



Vol. i., p. 12. Bisulcia ligustri ab. sundevalli, Lampa. This 

 variety is described by Lampa as : " Framvingarne sakaa hvita 

 flackar " (' Entotnologisk Tidskrift,' 1885, p. 50). This variety will 

 therefore fall before Haworth's var. coronula which is a very much 

 older name. 



Cuspidia, Chpmn., megacephala, Fab. 



Vol. i., p. 15, line 3 from bottom. For megacephalo read 

 megacephala. 



Cuspidia, Chpmn., strigosa, Fab. 



Vol. i., p. 16. Cuspidia strigosa var. bryophiloides, Hormuzaki. 

 This small dark variety was first described by Mons. C. v. Hormuzaki 

 of Czernowitz, and a comparison made with the type, as follows : 

 " On the 20th of June, 1884, I found here in Czernowitz, on a garden 

 plank, a freshly emerged specimen of Acronycta strigosa, which differed 

 so remarkably from the ordinary type, that it appeared to be worth 

 while to give this variety special consideration. The type is not par- 

 ticularly common with us. I frequently meet with them here in 

 gardens in June and the beginning of July, and in the mountains until 

 the end of July, settled on trunks of trees, planks, and similar objects. In 

 the evening they also fly to the lamplight. All my examples generally 

 agree pretty well with each other and with specimens from Germany ; 

 indeed, strigosa is one of those species which rarely vary in size, wing- 

 form, colour or markings, on which account I have made the following 

 description. 



Var. bryophiloides differs from the type, in the first place by its 

 small size. Those of my typical specimens before referred to, give an 

 average measurement of 2y mm., vory few examples reaching below 

 this (my smallest specimen measures 28-5 mm., the largest being 

 31 mm.), whilst var. bryophiloides scarcely reaches a wing measurement 

 of 25 mm. The fore wing is also strikingly narrower, measuring only 

 5 mm. in var. bryophiloidts. The inner edge of the hind wing is 

 darker, and this makes them appear longer. The head, antennae, 

 thorax etc. are of a dark brownish and ashy-grey coloration, the same 

 coloration in strigosa, which is only noticeable on the inner edge of the 

 front wing, around the arrow-like mark. These dark ground colours 

 spread out in the var. bryophiloides over the front wings, the inner 

 half of which is not at all a clear white mixture as one sees in stri- 

 gosa, also on the inner borders of the two transverse lines, and more 

 especially in that part of the wing between the elbowed line and the 

 reniform stigma as well as towards the outer margin. The orbicular 

 is also dark grey, whilst in strigosa it is pale, often with a dark centre. 

 There is also a darkening on the inner margin, at the base of the fore 

 wings, and also between the reniform and orbicular stigma. The 

 reniform and orbicular are much obliterated, one having only the con- 

 vex side of the reniform and represented by a fine black semi-circle, 

 with a slight yellow projection as in strigosa, but much darker and 

 less distinct. The elbowed line is represented by three small indistinct 

 black points, one of which is on the costal edge, the second in the 

 centre, the third in the second cell. These points are the only rem- 

 nants of the conspicuous, black, zigzag elbowed line, bordered internally
