triangular blotch at the base, and a broad 

 edian transverse bar, very dark brown (in 

 ent specimens in fine condition almost 

 ack) ; the space between these two con- 

 icuous marks, and also the space between 

 e bar and hind margin, are pale reddish 

 Town ; the margins of both the dark markings 

 are delicately bordered with white, and the 

 outer white border of the median bar expands 

 on the costa into a conspicuous white spot ; 

 the hind wings are pale dingy brown, with a 

 paler waved transverse line below the middle, 

 and a black spot above the middle. 



The MOTH appears on the wing at the end of 

 June and in July, and occurs in some abun- 

 dance in the lake districts of England and 

 Ireland, being particularly attached to the 

 holly. Mr. Eirchall and the late Mr. Bouchard 

 obtained it abundantly by beating holly trees 

 in the neighbourhood of Killarney ; but Mr. 

 Birchall thinks it resorts to the hollies for 

 concealment only, and not as a food-plant. It 

 is an extremely beautiful and distinct species. 

 (The scientific name is Emmelesia taniata.')

2-53. Haworth's Carpet (Emmelesia unifasciata]. 



253. HAWORTH'S CARPET. The antenna 

 are simple in both sexes ; the fore wings are 

 dull brown, with numerous transverse waved 

 lines, and a distinct double rivulet line just 

 beyond the middle ; the inner section of this 

 double rivulet line is white, the outer ferru- 

 ginous ; half way between this and the base, 

 is a second double rivulet line, much more 

 obscure ; between these two double lines the 

 area of the wing is darker than beyond them, 

 and there is a very evident, although not con- 

 spicuous, discoidal spot ; half way between the 

 exterior rivulet line and the hind margin is a 

 transverse series of pale spots, interrupted in 

 the middle ; and near the apex of the wing are 

 two short oblique black lines, or markings, 

 almost fused into one, and also a double, or 

 twin spot, as in Larentia didymata ; the 

 hind wings are pale, dingy brown, with a 



few waved darker lines, and a central darker 

 spot. 



The MOTH appears on the wing in July, but 

 is very rare ; the most copious capture I have 

 heard of is that of Mr. Hodgkinson, in 1865, 

 in the lake district of the north of England ; 

 Mr. Doubleday has taken it at Eppiug, and 

 Mr. M'Lachlan at Forest Hill. 



1st Ob*. 1 have adopted the name from 

 Doubleday's synonymic list and Guenee's 

 Species Genera/, but, without wishing to 

 imply that I agree with it : the insect before 

 me corresponds with the description of Phalcena 

 bifaciata of Haworth (p. 334), and figured by 

 instruction of the late Mr. Stephens, by Wood, 

 under that name (fig. 702) ; the figure of 

 unifasciata in Wood (701), also from the 

 same source, bears no resemblance whatever 

 to the insect I have described. Herrich- 

 Schaeffer's description of Aquilaria (Geo- 

 metry, p. 163, Xo. 151, and figured pi. 55, 

 fig. 336), is without doubt the insect under 

 consideration. Seeing that our three English 

 authors, Haworth, Stephens, and Wood, have 

 made two species out of one, and that all later 

 authors agree in combining them, and in drop- 

 ping the first name, bifaciata, I should have 

 preferred adopting Herrich-SchaefFer's name, 

 as combining the two others, and as admitting 

 of no doubt. 



2nd Obs. This pretty moth closely resem- 

 bles Coremtaferrugata, to be described further 

 on ; it appears quite out of place here. 



2-54. The Heath Rivulet (Emnielesia ericetata}. 



254. THE HEATH RIVULET. The antennae 

 are simple in both sexes ; the fore wings are 

 smoke colour, and are traveled by numerous 

 white bars ; the first of these is short, and 

 very near the base, and generally single, but 

 sometimes double; the second is nearer the 

 middle of the wing, nearly straight, and 

 always double ; the third is situated beyond 

 the middle of the wing, is bent and angled, 

 and always double. In some specimens the
