ON ORGYIA AUROLlJlbATA, GN., AT BEJAU. Il5 



chambers. Oue of these is occupied by the pupa, and when 

 the moth emerges she leaves this chamber containing the empty pupa- 

 case and enters the other, and so is separated by the diaphragm or 

 partition from the empty pupa-case, which is somewhat fragile, but 

 much more substantial than that of (K .yilnulida. The partition is 

 sufficiently yielding to make the side occupied by the pupa or moth, for 

 the time being, the larger of the two, but not so much so as to amount 

 to the absolute collapse of the other, though this condition is finally 

 nearly approached by that containing the empty pupa-case. 



I made no observation as to the manner in which the female 

 moth leaves the pupal and enters the imaginal side of the cocoon. 

 She moves about apparently with some freedom within the cocoon, 

 but without rubbing off any of the wool with which she is plentifully 

 clothed, and which gives her a very nice comfortable, furry, sealskin 

 sort of aspect. This, however, comes oil" completely during oviposi- 

 tion, and leaves the moth a very wretched unclothed scrap. The eggs 

 remain all winter in the cocoon amongst this wool. 



Orgyia aurolimbata. — Ovum : The eggs of this species, laid within 

 the cocoon, are very like those of (K sple)uli(la{ — yvhite porcelain appear- 

 ance) and are placed quite loosely amongst the wool with which the 

 cocoon is filled, and are rather flattened, especially on the basal side, 

 and at the approach of winter the eggs are still quite undeveloped. 

 They are, however, distinctly smaller than those of (K splonliila, c/:., 

 l'37mm. wide by 1-lOmm. high. They compare thus with those of 

 O. splendida and (>. antiqua : 



Larva (description made in the field) : The larva of 'K aiindiin- 

 hatu varies much in size (as in other Orgyias as to 3 and ? ), up to 

 over an inch long. Jhnsal ricir — Lemon -yellow, more orange on the 

 first four abdominal (tufted) segments, with a broad dorsal black line on 

 2, 8, 4, 9, 10, 11 and 12, ending in a black tuft on latter segment. 

 Front lateral tufts on 2nd segment (prothorax) black. Eversible glands 

 on 10 and 11 yellow. The tubercles on 5, G, 7 and y, which are 

 fully tufted in the last skin, are well-haired in the penultimate one. 

 On these four segments, tubercle i is then small, transverse, ii is much 

 larger, pear-shaped, with the small end dorsal, the larger end outwards 

 and the anterior margin being curved, i lies in the hollow and the broad 

 end of ii reaches round so as to be extei'nal to it. On 9 and 10 tubercle i is 

 a mere dot, and ii a small oval patch behind it. Lateral ricir —Tubercles 

 iii and iv yellow, well-haired, iii the larger, iii in a much interrupted, iv 

 in a nearly continuous, yellow line, the rest of area black, h&li way up 

 to ii. Head black, tufts on 2 and 12 black, on 5, 6. 7 and 8 yellow, 

 orange or deep brown, other hairs whitish. Legs and prolegs orange, 

 underside orange-yellow% a posterior tuft on 18. 



Pupa: The J pupa has a length of 10mm. -11mm. ; general outline 

 similar to that of other Orgyias {antiiina, etc.). It is of a deep brown
