106 THE ENTOMOT.OaiST's RECORD. 



very stout seta in the subdorsal region, and a strong tubercle below. 

 Beneath the prothorax there are, on each side of the median line, four 

 tubercles arranged quadrilaterally. On the anterior portion of the 

 mesothorax, there is a pair of tubercles on the dorsum, with a pair 

 behind, followed by another pair ; on each side below these, are tw^o 

 pairs of tubercles ; beneath, there is a stout tubercle outside the 

 proleg, and a smaller one on the inner side, with the row of three 

 tubercles on the proleg betw^een them. The metathorax is similar, 

 except that on the dorsum there are only two pairs of tubercles, with 

 three instead of four tubercles beneath them. The arrangement of 

 the tubercles, as above described, agrees very well with that I have 

 seen in Xeptirtda cnj/itdla, and also in Trifitrcula ivumDidclla, but 

 from what I have seen of other species of Nepticula, I think many of 

 them would show a different arrangement. 



Pupa: The total length of the pupa is about l-6mm. It is rather 

 stout and ochreous-yellow. The spiracles, which, in the larva, are very 

 inconspicuous, are here large, and somewhat raised above the general 

 surface. Most of the abdominal segments have a dorsal row of stout, 

 brown-tipped spines, about twenty on the anterior of the segment, 

 and the dorsum of the 10th abdominal carries two long spines directed 

 upwards, that is at a right angle to the general line of the dorsuna. 

 These two spines must be very useful in anchoring the pupa to the 

 silk inside the cocoon, when the pupa is thrust out sufficiently far for 

 the emergence of the moth. I have seen one or two tubercles with 

 setas in the subdorsal region, but they do not seem to be present on all 

 the segments.

Variation of Aglais urticae. 



By GILBERT II. RAYNOR, II. A. 

 I am indebted to M. Lambillion, of Jambes, Belgium, for the 

 information that he had already named two of the aberrations of A. 

 urticae included in my paper on this species in Ent. Bee, vol. xxi., 

 p. 7. They are ab. luteomarginata ( = my ab. fidvomarginata), and ab. 

 bolandii ( = my ci(neati))iittata). His names supersede mine by virtue 

 of their priority. Appended are the original descriptions —
