238 LEPIDOPTERA. 



black spot ; cilia white, barred with black ; a ceutral blackish 

 spot on the hin'd wings and two blackish cloudy spots on the 

 costal margin, from the second of which commences a slender 

 series of blackish streaks on the nervures ; body greyish- 

 white ; legs whitish, first pair broadly barred in front with 

 black. 



Hardly variable, except in an occasional extension of the 

 blackish clouding to the hind margin and in some degree 

 over the pale portions of the fore wings. In some of the 

 specimens reared by Dr. Chapman the smoky ochreous space 

 outside the reniform stigma is large and ovate, paler, some- 

 times whitish -grey ; in others the orbicular stigma is strongly 

 black-ringed ; or the pale portion near the costa and base is 

 marbled with black. 



On the wing from the middle of May to the middle of June. 

 It has been reared in September as a second generation. 



Laeva cylindrical, tapering a very little behind ; head 

 deeply notched or almost bifid above, black ; body, with the 

 legs, black, deep velvety black on the back ; across the back 

 of each segment, except the head, is a broad rather rect- 

 angular blotch of a rich golden yellow ; on the second 

 segment are six long black spatulate hairs, and segments 

 five to twelve have each a pair of similar long black pointed, 

 but spoon-shaped hairs, of so conspicuous a character that 

 from them alone the creature may be at once recognised ; on 

 the anal segment are four such hairs, but on segments three 

 and four are two pairs of ordinary shorter bristles. This 

 remarkable costume is that of full growth, or, at any rate, 

 only after the fourth change of skin. The appearance of the 

 younger larva is admirably described by the Rev. Hugh A. 

 Stowell : " I was looking over some standard roses when I 

 noticed upon a leaf what appeared to be a recent deposit of 

 the same nature as that which proved so injurious to Tobit's 

 eyesight. A nearer inspection, however, resolved it into a 

 lepidopterous larva, half doubled round upon itself and
