brown with a white spot at each extremity, and each spiracle is 

 situated in an oblique patch of pinldsh purple, bordered especially 

 above with whitish green; these oblique markings have a different 

 direction to those of such normal Sphingidae as constitute the genera 

 Sphinx, Smerinthus, &c., their dorsal extremities tending forwards as 

 in some of the Notodontidae, a very noteworthy peculiarity, because it 

 breaks down one of the most obvious characters for distinguishing the 

 larvae of these two families ; the anterior spiracle has no such orna- 

 mentation ; ventral surface, including the claspers and legs, dull 

 pinkish purple. 



Maceoglossa Fuciformis. 

 Feeds on the leaves of Lonicera periclymenum (common honey- 

 suckle), and is full-grown about the middle of July, when it rests in nearly 

 a straight position, the anterior extremity being very slightly elevated, 

 and the legs crowded together near the mouth. Head prone, narrower 

 than the 2nd segment, into which it is partially received ; the crown 

 is rounded and not conspicuously divided : body nearly cylindrical, 

 slightly attenuated anteriorly, the divisions of the segments indistinctly 

 marked, and each segment is transversely divided into sections, which 

 are beset with a series of minute slightly raised warts, giving the surface 

 the appearance of shagreen ; the 12lh segment is furnished with an 

 acutely-pointed scabrous horn, which is nearly straight, but in a very 

 slight degree bent upwards at the extremity. Colour of the head dull 

 rather glaucous green: dorsal surface of the body glaucous green, with a 

 darker mediodorsal stripe, evidently due to the proximity of the intestinal 

 canal, visible through the skin; lateral area apple-green, the series of 

 minute warts already described being yellow; the spiracles are reddish, 

 with a white dot at each extremity; each spiracle occupies the centre of 

 a roundish purple-brown spot, which is again surrounded by an indis- 

 tinct yellow ring : the whole of the ventral surface, including the legs 

 and claspers, purple-brown, the division between this and the bright 

 green of the sides being very marked ; the caudal horn is of the same 

 purple-brown colour, and rather paler at the tip. I am indebted to 

 Mr. Doubleday for the opportunity of describing this larva, specimens 

 of which I had never previously seen. 



Hadena suasa. 

 In confinement feeds voraciously on Polygonum aviculare (common 

 knot-grass), and is full fed about the third week in July. It eats prin- 

 cipally by night, resting by day, in a straight position, on those stems
