are short, broad, and rouuded at the tip ; they 

 are gray, with smoky-brown mat-kings, which 

 are numerous and conspicuous on the costal 

 margin ; the discoidal spot is intensely black, 

 but not very large; there are numerous closely 

 approximate transverse markings between the 

 costal and sub-costal wing-rays ; the con- 

 tinuity of this series is broken at two-thirds 

 of the distance between Che base and tip, by 

 two pale gray markings of similar shape ; the 

 disk of the wing is traversed by narrow 

 waved Hues, most of which originate in the 

 costal markings already noticed, but two differ 

 from the rest in originating on the inner 

 margin, and not reaching the costal margin, 

 but uniting before they reach the sub-costal 

 ray, from a loop which touches and encloses 

 the discoidal spot ; there is a pale zigzag line 

 parallel to the hind margin, and a slender 

 interrupted black line on the margin itself : 

 the hind wings are gray, with transverse 

 markings : the head, thorax, and body are 

 gray ; the last with the penultimate segment 

 darker, especially on the sides. 



The CATERPILLAR is thus described by Mr. 

 Crewe : 



" Short and stumpy ; the ground colour is 

 dirty yellowish green. The sides and centre 

 of back slightly tinged with rose-colour, down 

 the centre of the back is a row of very indis- 

 tinct dusky spots, becoming confluent in a 

 black line at the anal segment, and bordered 

 by an interrupted black line. On each side 

 is a row of slanting tubercular flesh-coloured 

 stripes ; the head and fore feet are black ; it 

 feeds on the crtkins of sallow in spring, and is 

 full-fed by the end of March and beginning of 

 April. In appearance it much resembles the 

 caterpillar of Eupithecia isogrammata. When 

 full fed, it comes out of the sallow catkins, and 

 spins a slight cocoon among earth, roots of 

 grass, and moss. The CHRYSALIS is pale golden 

 yellow ; the abdominal divisions dusky ; the 

 thorax and wing-cases have a slight greenish 

 tinge ; the eyes are prominent and blackish ; 

 the body short and curtailed." 



The MOTH appears on the wing in June, 

 and has been found both in the north and 

 vest of England, and by Mr. Birchall at 



Killarney, in Ireland. (The scientific nama 

 is Eupithecia tenuiata.) 



293. The Maple Pag (Eupithecia suboiUafa). 



293. THE MAPLE PUG. The antennae of 

 the male are very slightly pectinated, or 

 rather ciliated, in this respect differing from 

 all the other British species of the genus ; it 

 is a very small species, the wings scarcely 

 pointed, and the markings very indistinct; the 

 fore wings are pale grayish brown ; there is 

 an indistinct discoidal spot, and the other 

 mai'kings are transver.se., waved and inter- 

 rupted, and, with the exception of the slender 

 interrupted black marginal line, none of them 

 present characters to describe ; the area near 

 the hind margin is the darkest, end is tra- 

 verse ' by a pale zigzag line, which commences 

 on the costal margin, and descends to the 

 anal angle ; the hind wings are paler at the 

 base than the fore wings, but otherwise of the 

 same colour, and the markings, such as they 

 are, are rather more distinct than on the fore 

 wings. 



The MOTH appears on the wing at the end 

 of July, and was discovered by Mr. Double- 

 day, in Cambridgeshire, and subsequently by 

 Dr. Knaggs, among maple trees, at Saltwood, 

 near Hythe. (The scientific name is Eupi- 

 thecia subciliata.) 



Obs. Mr. Doubleday pays, he believes 

 this insect to be the DositJiea circuitaria of 

 Stainton's " Annual," but it bears no resem- 

 blance to the figures in Hubner'sand Herrich- 

 Schteffer's works. Mr. Stainton has an Eupi- 

 thecia subciliata also (Manual, vol. ii. p. 90), 

 but I am uncertain whether the present species 

 is intended ; and the reference in the Index 

 to E. subumbrata as a synonyme makes the 

 matter still more obscure. 



294. THE OAK-TREE PUG. The fore wings 

 are neither long and pointed, nor broad and 

 rounded ; they are of a pale gray colour, with 

 the slightest possible tint of olive ~r>en on
