THE ENTOMOLOGIST. Q4l 



margin of the 2nd segment is also black ; the lateral white 

 stripes arc waved, and all three are interrnpted at intervals 

 and broken up into dots ; there is a pale and tolerably broad 

 medio-ventral stripe, delicately bordered on both sides with 

 pure white ; on each side of this is a similar stripe, rather 

 indicated than expressed ; between the ventral and anal 

 claspers the ventral surface is pale. I am indebted to Mr. 

 Barrett and Mr. Wright for a supply of this larva. The 

 moth is certainly the B. rhomboidaria of Gueuee, while B. 

 rhomboidaria of Stephens is as certainly ray B. perfuraaria, 

 the larva of which is previously described in the * Entomolo- 

 gist :' whether these two insects be considered identical or 

 distinct is immaterial, since it indicates rather the character 

 of the entomologist than of the insect : the ablest, most 

 fluent and most controversial writers occupy firm ground in 

 contending that the two are identical, whilst those close and 

 patient observers, who reluctantly and diffidently express 

 their views in print, miiformly regard them as distinct. —

Description of the Larva of Fidonia atomaria. — Feeds on 

 Rubus fruticosus (bramble), and was full-fed on the 17th of 

 July : it rests in a nearly straight position, with the head 

 prone and slightly exserted ; it is of nearly the same width 

 as the 2nd segment ; the crown gibbose and slightly notched : 

 the body is almost uniformly cylindrical, with a manifest 

 lateral skinfold. The face has a slight resemblance to the 

 human face, the central plate (or nose) being very distinct, 

 but very flat ; on the upper part of each cheek is a pale 

 patch, in which is a dark eye-like spot, and above this is a 

 dark crescentic mark much resembling an eyebrow. Colour 

 of the body umber-brown of two shades, arranged in longitu- 

 dinal stripes ; medio-dorsal stripe broad and pale, intersected 

 throughout by a pair of very delicate slender indistinct darker 

 lines ; on each side of the medio-dorsal stripe is a narrower 

 dark stripe, exterior to which is a pale stripe of the same 

 width ; and between these, partially on each, is a series of 

 small white spots, one on the posterior margin of each seg- 

 ment ; a broad dark stripe succeeds, and then a broadish 

 pale stripe, which comprises the skinfold and spiracles ; ven- 

 tral surface pale brown, with two distinct broadish dark stripes, 

 which extend from the third pair of legs to the ventral
