have hoped for single-handed. From Michael Ward and 
Mark Kershaw I have received fresh larvae and fresh food, 
and to them special thanks are due. The first specimen 
appeared May 21st, 1873.— C. S. Gregson.

Description of the Larva of Depressaria rotundella .— 
Length two-eighths of an inch, slender, cylindrical, striate; 
colour light yellowish, with three parallel lines, the dorsal 
line rather narrower and less pronounced than the subdorsal 
lines. Head black, broad, divided; corslet light; behind 
the head, broader than the head, and forming full half a 
circle, and having a dark, distinctly-defined outer edging on 
the subdorsal region, are two dots, the first one uppermost, 
and on the spiracular region one well-defined dot; from 
these marks a single spine springs ; anal segment immaculate ; 
feet light. Feeds on the pinnae of wild carrot-leaves (Daucus 
Carota) in June, at Bowtb, Ireland; at Douglas, Isle of 
Man; and in South and North Lancashire. Full fed in 
July.— Id. 
Description of the Larva of Platyptilas gonodactylus .— 
Length fully half an inch, stout, attenuated towards both 
extremities, subtranslucent, slightly hairy; ground colour 
pink. Head small, shining, black; corslet dark, broad, 
rhomboidal, with two black dots below it placed longi¬ 
tudinally; 3rd and 4th segments dilated, and a ring of 
various-sized spots on each, the following segments having 
a ring of spots, and an additional spot on the hind subdorsal 
region ; anal plate small; dorsal line broad, pink oehreous- 
brown, darker and narrowed on the last segment; subdorsal 
the same colour as the dorsal line; subspiracular wavy; 
spiracles distinct, black; feet black. The larvae feed in the 
young flower-shoots of Petisites farfara in April, causing 
them to be stunted and droop; they leave these stems, and 
enter more advanced flower-stalks, towards the end of April, 
a little below the flower head, and live beneath the seeds, 
eating them from below, or they enter a well-grown flower 
before it is open, causing it to burst on one side, and take 
their place amongst the seeds as soon as they have eaten 
out a home to live in: they appear in the perfect state 
in May. I have gone fully into this description, because I
