with which it is covered ; the anal claspers are spreading. Colour of the head dark 

 brown, and, like the body, iridescent: dorsal surface of the body dark rich umber-brown, 

 clouded and variegated with lighter and darker shades; a darker shade forms an ob- 

 scurely defined mediodorsal stripe, which emits at the posterior marfrin of each seg- 

 ment a branch, extending obliquely downwards and forwards, until it reaches a broad 

 dark lateral stripe that terminates abruptly on a level with the spiracles, which are 

 wainscut-brown ; ventral surface, extending upwards to tlie spiracles, purple-brown, 

 with a bloom like that of a ripe plum, and delicately reticulated ; 12lli se^'nient 

 crowned with two dorsal yellow spots placed transversely ; dorsal and ventral surfaces 

 separated on the 2nd, 3rd, I2lh and 1.3th segments by a yellow line; legs and claspers 

 reddish brown. Descends to the ground and undergoes pupation just below the sur- 

 face of the earth: the perfect insect appears in May. I was indehied to Mr. N. Cooke 

 for a supply of these larva in the autumn of \S6\.— Edward Newman. 



Description of the Larva of Acidalia rubricala. — The larva when full fed is not 

 quite an inch in length; in shape rather slender, tapering towards the head ; the head 

 itself is notched, having the lobes rounded and swelling out wider than the second 

 segment ; the whole body is ribbed with transverse rinjjs. The ground colour is gray 

 or ochreous on the back, paler on the belly. The dorsal line is composed of two very 

 fine du>ky threads; there is a thicker and darker subdorsal line, commencing on each 

 lobe of the head, and vanishing again after the f.iuilh segment ; as far as this extends 

 there is between it and the dorsal line a pule gray stripe; on the uext live segments 

 both these subdorsal lines reappear only as a light or black spot at the segmental 

 divisions, while on the back of the same segments there are five elongated dusky 

 lozenges faintly edged with black; the remaining segments are paler both in ground 

 colour and in distinctness of lines. The spiracles are black, placed in a drab longi- 

 tudinal ridge, which is bordered above by a fine Mack line and below by a wider one. 

 All the dark lines and marks become much fainter as the larva approaches its final 

 change. The pupa is apparently placed in a slight cocoon under moss: the moth 

 appears on the 29lh of June. — Rev. Julia Iletlins, in the '■ EnlomologisVs Monthly

Description of the Larva of Toxocampa cracces. — Larva (when full-grown) IJ to 

 1 J inch in length. When viewed from above it tapers towards the head, and still more 

 towards the posterior end; but when seen sideways appears almost uniformly long 

 and sleu<ler. Its manner of walking is a partial looping of the first six segments: the 

 first two ventral prolegs are very slightly shorter than the others, but to such an extent 

 as to he scarcely noticeable, and it generally assumes an undulating posture in repose 

 along the stem of its food-plant. Along the back, commencing on the head, is a dark 

 brown, very finely mottled, broad stripe, widest along the middle segn)eut; and with 

 an additional widening on the eleventh segment; in the centre of this is a thin, rather 

 paler stripe, enclosing the very dark brown dorsal line. The subdorsal stripes are 

 double, brown, with a paler ochreous-brown ground, followed by a pale stripe of 

 ochreous, enclosing a very thin brown line; the lateral lines double, dark brown, 

 extending from the moulh to the anal prolegs; edged above with black at the anterior 

 portion of each segment; the upper one widening below in the middle, along which 

 are some black dots. Belly and legs brown. Within the dark portion of the back, on 

 each segment, are placed four black dois in the usual order, and on the eleventh seg- 

 ment there is an additional black dot on each side, outside the dark region. Sub- 

 dorsal lines, also, containing two black dots and a minute ring. Went to earth ou the
