40 Mr. Saunders's Remarks 



I expect specimens from this gentleman. It is I'rom size and the 

 brilliant yellow colour of the head and first rings unquestionably 

 a new species. 



In August I found on another pamplemos bush two more 

 cocoons resembling nearly exactly those of the male described, 

 but rather smaller and more conical. One of them came out on 

 the 22d of October, warm moist weather, and I got, but much 

 injured, the following species, which, from its agreeing so closely 

 with O. {Cryptothelea, Duncan) Macleayi, I have named, 



Oiketicus (Cryptothelea) consortus. (PI. V. fig. 7.) 



Body brown, covered with coarse longish brown hairs, abdomen 

 brownish, nearly naked, last annuli yellow, with dark margins : 

 anterior legs with marginal brown hairs ; posterior nearly naked ; 

 middle intermediate in this character ; antennse pectinate to the 

 tip, dark brown. Wings uniform brown, broad. 



Plate V. fig. 1, Oiketicus terlivs, natural size; fig. 2, cocoon: fig. 3, pupa 

 case ; fig. 4, exhibiting the ribbed appearance of a ring ; fig. 5, 

 male suspended at rest; fig. 6. cocoon of Oiketicus consortus; 

 fig. 7, 0. consortus natural size; fig. 8, case found Delima 

 sarmentosa.

The larvse are enclosed in a silken case, fortified on the outside 

 with pieces of stick of various lengths, generally about half an 

 inch on the main part, but towards the lower end there are usually 

 a few from one to three inches in length, in the centre of which 

 the lower end of the silken case protrudes free from the sticks, 

 and is very flexible. Through this aperture the larva discharges 

 its excrement and exuviae. The upper or head extremity of the 

 case is a beautiful tissue of soft silk, forming a tube half an inch 

 in width, through which the larva emerges to feed and change its 

 position. It frequently comes out half its length, but most com- 

 monly only protrudes its six true feet and the four first segments
