ChILO MUCRONELLUS. 



Plate CLIX, fig. 6. 



I received eggs from Mr. C. G. Barrett on the 21st 

 of August, 1871. They were laid in a cluster and 

 enveloped in a little ball of whity-brown fluff, from 

 which the larvss began to appear on the 26th. 



The larva when first hatched is diDgy blackish- 

 green with black head and plate behind it. (William 

 Buckler, 26th August, 1871 ; Note Book I, 127.) 



On the 10th of July, 1881, I received from Lord 

 Walsingham four larvas inhabiting stems of a Gar ex 

 about an inch above the root, and the sign of its 

 presence is a small round hole in the stem two or 

 three inches above the root, or about two and a half 

 inches. 



?he larva is five-eighths of an inch in length, of 



slender proportions, tapering from the fourth segment 

 to the head as seen sideways, while viewed from above 

 it only tapers from the third ; the head is smaller 

 than the second segment, the last four segments 

 gradually tapering. The anterior legs are moderately 

 developed, the ventral and anal legs very little deve- 

 loped, and their extremities are encircled with minute 

 hooks. The colour of the head is reddish-brown, 

 with the mouth, the ocelli, and a lateral streak all 

 black ; there is a reddish-brown plate on the second 

 segment with darker brown front margin and dorsally 

 divided towards the hind margin with cream-colour, 

 bearing a short dark brown curved mark on either 

 side of the division on the hind margin, which is of a 

 creamy tint all round the very edge of the plate 

 except in front. The body above on all the other 

 segments is of a dingy olive-brown ; the soft and 

 velvety skin is totally without gloss, but the head 

 and the plate on the second segment are highly 

 polished ; the dorsal stripe shows faintly through of
