Mr. Doubleday, were full-fed on the 14th of June. — E. 

 New man. 



Descripfio)} of the Larva of Nonngria pudorina. — The 

 eggs are laid on Arundo Plivagmites (coninion reed) and seve- 

 ral grasses, on which the larva feeds. The full-grown larva 

 rests in a perfecdy straight position, and when disturbed falls 

 off and forms a lax ring, but almost immediately unfolds to 

 resume the straight position. Head porrected, of the same 

 width as tlie 2nd segment: body obese, cylindrical, tapering 

 towards the anterior extremity. Colour of head and body 

 pale wainscot-brown : head glabrous, with darker reticulated 

 markings, and having two approximate, longitudinal, dark 

 stripes on the face, which diverge at the clypeus ; body with 

 two closely approximate, but very narrow and very indistinct, 

 medio-dorsal black stripes, exterior to which are numerous 

 very delicate reticulated or rivulet markings, of a smoky black 

 colour; again, exterior to the somewhat wide space occupied 

 by these, is a distinct double stripe on each side, of a dark 

 smoke-colour, almost black ; this has the exterior margin 

 darker than the interior margin, and bounded by a narrow 

 lighter stripe, which makes it still more conspicuous ; exte- 

 rior to this are lour lateral stripes, each composed of multi- 

 tudinous delicate markings, the lowest on each side contain- 

 ing the perfectly black spiracles ; below the spiracles is a 

 broader pale stripe, and then a delicately reticulated surface 

 of rather a darker hue; each segment has two very small but 

 intensely black dots on its dorsal surface, equidistant from 

 the double medio-dorsal stripe and the next dark stripe ; and 

 ranged along each side is a series of black dots, one above 

 each spiracle, and another behind each spiracle ; and similar 

 black dots occur below the lowest lateral stripe ; ventral sur- 

 face, legs and claspers of the same pale wainscot-brown as 

 the general dorsal surface. I am indebted to Mr. Tliomas 

 Brown, of Cambridge, for this larva. — Edward Newman. 



Description of the Larva of Nonagria liitosa. — The egg is 

 laid in August, September, and even occasionally so late as 

 October, on the stems of Arundo Phragmites (reed) ; and the 

 young larva very shortly emerges, and eats into the stem, de- 

 scending towards the roots, on which it feeds below the sur- 

 face of the ground ; it feeds during the remainder of the 

 autumn, and probably also throughout the winter and spring,
