weed, hiding themselves by day near the surface of the 

 ground, and remaining motionless during daylight. The full- 

 grown larva rests in a perfectly straight position, so far as 

 the sinuosities of the plant will allow, on the slender stems 

 of Convolvulus arvensis (the common field bind-weed), the 

 legs holding the stem slightly, but the claspers more firmly 

 attached, the anal pair of claspers stretched out behind: 

 when annoyed it falls to the ground, rolled in a lax and 

 imperfect ring, the head turned on one side : the head is 

 exserted and porrected ; it is of almost exactly the same 

 width as the '2nd segment, and emits a considerable number 

 of straight hairs : the body is elongate and rather slender ; it 

 is attenuated towards the anal extremity ; on the 2nd seg- 

 ment is a glabrous shining plate of a semicircular figure, the 

 convex side being posterior ; the remaining segments are 

 distinctly marked, and each is slightly swollen in the middle. 

 The colour of the head is pale rather shining brown, with eight 

 irregular longitudinal series of aujorphous spots; the plate on 

 the and segment is dingy brown, intersected by three paler 

 stripes; the dorsal area of the body is striped with brown of two 

 shades, there being three pale and four darker stripes ; the 

 paler stripes are medio-dorsal and lateral, the darker stripes 

 alternating with them, and each darker stripe having in each 

 segment a paler wart-like spot, which emits a hair; the 

 lower dark stripe on each side is compound or composed of 

 several minor stripes ; the ventral is decidedly paler than the 

 dorsal area, and the division between the two is abrupt and 

 clearly defined ; there is a medio-ventral series of black spots, 

 connected by a slender and indistinct stripe of the same 

 colour ; the black spots are most conspicuous on the 5lh, 

 6th, 7th and 8lh segments : the legs are rather long, pale 

 semitransparent brown, with black rings ; the claspers are 

 nearly concolorous with the ventral area. 1 am indebted to 

 Mr. D. T. Button for a most liberal supply of these larvae, 

 which were full-fed on the 14th of June, and then went down 

 to undergo pupation on or under the surface of the earth. 

 Since this description (intended for the July number of the 

 'Entomologist') was in type, Mr. Buckler has published a 

 description of the larva in the 'Entomologist's Monthly 

 Magazine,' comjnled with his usual care and skill ; but he 

 introduces an observation that seems scarcely needed. " The
