upper surface of those leaves winch projected far enough to catch it, heing covered with 

 honey-dew, and the ground, for a short distance from the foot of the tree, appeared 

 quite damp with the same suhstance, while the more distant part was dry. But the 

 funniest part of the affair was, that the rays of the sun were reflected from this falling 

 shower, so as to form the prettiest little rainbow (or rather dew-how) imaginable, exhi- 

 biting the prismatic colours, and being precisely similar, only on a smaller scale, to the 

 effect I have often produced by throwing a stream of water from a large garden-sy- 

 ringe against a dark-coloured wall opposite the sun, with sufficient force to break the 

 stream into very fine spray. — Geo. Luxford ; Ratcliff Highivay, July 13, 1841. 



41. Laphria nigra. The pupa of this insect inhabits decayed wood. The head, 

 thorax, rudiments of wings, and eight segments of the abdomen are distinctly formed 

 on the outside of the case. There are four large and as many small spines on the head, 

 and the same number occur close together on the tip of the abdomen. The back of 

 each segment of the abdomen is also armed with a transverse row of small spines. The 

 head and thorax are smooth, but on the sides of the abdomen there are a few bristles.

Anterior wings long and slender, somewhat rounded at the hinder margin, and di- 

 lated near the base of the inner edge ; brownish, or whitish-grey, slightly dusted with 

 brown, with a black-brown streak towards the costa, the inner edge reddish ; cilia 

 dirty-brown, paler in the 5 : posterior wings of the ^ whitish, of the J brownish- 

 grey : eyes black ; head and thorax brownish-grey : abdomen cylindrical, longer than 

 the wings ; of the 3^ brownish, of the $ whitish-grey : antennsB white, with brown ra- 

 dii, the latter in the ^ disappearing before the apex. The larva inhabits the stalks of 

 Arundo Phragmitis. The above description of this recent addition to our Fauna, made 

 by my friend H. Doubleday, Esq., I have attempted to draw up from Ochsenheimer, 

 accompanied by the collation of the figures of the insect, in my copies of Hiibner, Es- 

 per and Engramelle, trusting that it may suffice for recognizing it, by any person who 

 may be successful in capturing a specimen, the example found by Mr. Doubleday 

 being too much injured for description. The insect (excluding the antennje) closely 

 resembles a Leucania, so that it might readily be mistaken for one in the hurry of col- 

 lecting, and by twilight ; lepidopterists therefore would do well to search diligently in 

 places where the plant upon which it feeds abounds, for a chance of meeting with it, 

 amongst the insects of that genus, which frequently abound in marshy places. — /. F.
