gives the positions, and remarks on the variable number of the bristles 

 at the anal extremity of the pupa ; and says that the moth emerges in 

 a fortnight. 



In the same work is a monograph, if possible still more elaborate, 

 of another fir-destroying species, Tortrix murinnna, a mottlcd-browii 

 insect, which being also very abundant and destructive in Soutl 

 Germany (Lower Austria, Moravia and Silesia), may some day be 

 discovered in this country. 



The larva is described as rather flattened, thickest in the middle 

 light bistre-green with dark green dorsal vessel, sides and ventral regior 

 yellower, head and dorsal plate shining black with a whitish collar 

 spots dark and hairs yellowish. When full-fed it leaves the fir tree 

 and assumes the pupa state in or on the ground. This is from theendi' 

 of May to the end of June, and the moth emerges in a fortnight. } 



These two species furnish splendid examples of common namesl 

 murinana being called " White-fir-shoot-Tortrix,"* and rufimifrani 

 "Eed-headed-white-fir-shoot-Tortrix."

DESCEIPTION OP THE LARVA OF CR AMBUS PRATELLUS. 

 BY GEO. T. rORRITT, F.L.S. 



Several moths of this species I took here on June 30th last yeai 

 deposited eggs, and two batches of them I dropped among grasi 

 planted in a large flower pot, I do not know when they hatched, and 

 indeed, have no further notes on them until September 12th, when '.-i 

 found the larvae were about three-eighths of an inch in length, ane| 

 were living in silken galleries, spun at the bases of the grass-sterm 

 above the ground, and in some cases between grass-stems and thd 

 sides of their plant pot. Twelve days later, on the 24th, I examine<e 

 the pot again, to find the larvae had grown rapidly, had eaten nearW 

 all the growing grass, and were wandering about the sides of the pox 

 and on the gauze covering. I then described them as follows : lengtll 

 about five-eighths of an inch, of average bulk, and of the usuffl 

 Crambus-shape ; head slightly narrower than the second segment, i 

 has the lobes rounded, and is (as is also the frontal plate) highh 

 polished ; body cylindrical above, slightly flattened ventrally, of nearl; 

 uniform width, tapering only a little towards the anal segment ; seg)| 

 mental divisions well defined ; the tubercles all polished, large ami 

 prominent, the dorsal four oblong-oval in shape, and placed end oppoi 

 site end, giving the appearance of two transverse ridges on eacl'
