called is really a distinct species from Uria troile. A variety it certainly is, but 
I think something more than the white line round the eye is necessary to constitute it 
a species. At some future time I may perhaps trouble you with a few remarks upon 
this subject.—J. Edmund Harting; Kingsbury, Middlesex, August 5, 1864. 
Description of the Eggs and Larve of Chortobius Davus—For the last three or 
four years I have felt very anxious to obtain larve of this species, and this season my 
efforts have been crowned with complete success. On the 12th of July I puta female 
of this species into a pill-box, and the next day she deposited eleven. eggs, which 
hatched on the 25th of the same month. The eggs are barrel-shaped and ribbed : when 
first laid they are of a beautiful green colour, but after a day or two they become 
marbled all over with brown. The larve, when first hatched, are of a dull flesh-colour, 
with five longitudinal reddish brown stripes, two on each side, and one down the back. 
When I found my larve crawling about in the pill-box I went down to Hatfield Moors 
for such plants as I could find in the haunts of this butterfly, although I always 
believed the beak rush (Rhyncospora alba) to be its food-plant, on which my lative are 
now feeding and doing well. I have since been to the Moors and found more larve 
feeding upon this plant, which seems to be their only food. They feed exposed by day. 
The larve are now about a quarter of an inch in length, of a dull green colour, with 
the five longitudinal stripes pale reddish brown. Head brown.— Samuel Hudson ;

Description of additional Varieties of the Larva of Eupithecia fraxinata of Crewe. 
During the past spring I was fortunate enough to get a small batch of fertile eggs of 
Eupithecia fraxinata from a pair of moths bred in confinement. Amongst the larve 
reared therefrom were some very beautiful varieties, the fullowing description of which 
may perhaps interest the readers of the ‘ Zoologist. I am happy to say that my friend 
Mr. Buckler has, with his usual skill, executed some most life-like coloured drawings. 
Var. 1.—Ground colour deep velvety green. Central dorsal line wanting. Sub- 
dorsal lines represented by a series of pale yellowish white spots. Spiracular line 
yellowish white. On the centre of each segment, between the subdorsa) spots and 
spiracular line, a rather large purple blotch. Belly whitish green; with a central dark 
green line. 
Var. 2.—Ground colour dull reddish purple. Central dorsal line deep dusky 
purple, enlarged into an arrow-shaped blotch at the segmental divisions. Subdorsal 
lines dull orange, much broken. Spiracular line bright yellow, orange in the centre, 
spotted with purple at the segmental divisions, and bordered broadly on the lower side 
with dull purple. Anal tip of central dorsal line reddish. Belly greenish or yellowish, 
with a central, narrow, purple line. 
Var. 3.—Ground colour pale yellowish olive. Belly paler than rest of the body. 
Central dorsal line deep purplish red, enlarged at the centre of the segmental divisions, 
much paler between, very dark on the capital and anal segments. 
dull yellow, purple at the centre of the segmental divisions. 
blotched with purple at the centre of the segmental divisions. 
Var. 4.— Uniform bright velvety green. Central dorsal and subdorsal lines purple, 
the former very faint, the latter only appearing in detached spots at the centre of the 
segmental divisions. Spiracular line pale yellow, blotched on the upper side with | 
Subdorsal lines
