468 NOTES ON ZELOTYPIA STACYI, AND AN ACCOUNT OF A VARIETY, 



be a distinct species as it differed materially from any he had 

 previously seen. These specimens form the subject of the following 

 notes. 



Larva — Length 122 mm.; width of head 11 mm. 



The larva of Z. Stacyl is long, cylindrical, and fleshy, pale 

 yellow above ; the divisions between the segments inclining to 

 reddish brown ; the first three segments rather bright i-ed, the 

 following segments, with the exception of the last two, provided 

 ■with three pale testaceous spots in the middle and two on each 

 side ; of these the middle spots are transverse, one being placed in 

 front of the two others which are much smaller and situated near 

 the posterior margin ; the head is black and finely rugose j legs 

 small, the claws black ; stigmata of the usual number. 



The larva makes its burrow in the limbs, or occasionally in the 

 trunk, of the Eucalypt {E. tireticornis] locally known as the grey 

 gum. It is veiy active, and like the Charagire, forms a bag-like 

 covering of triturated bark about the opening of its burrow, which 

 it closes before pupating with a thick pad resembling a gun-wad. 



Pupa — Length 96 mm. 



The pupa is very long and cylindrical, slightly thickened towards 

 the anterior extremity, with the segmentation, particularly of the 

 thorax, unusually well-marked ; the abdominal segments beyond 

 the ex;tremity of the wing-coverings provided with a transverse 

 serrate horny ridge near the anterior margins ; below the 7th to 

 10th segments are provided with similar but less prominent 

 ridges ; the anal extremity armed, both above and below, with 

 small sharp spines. 



The likeness between Zelotypia and Charagia is as apparent in 

 this stage as in the larval condition, and the wonderful activity 

 of the pupa in its burrow is equally noticeable in both genera. 

 The power of rapidly ascending or descending the precipitous 

 walls of the burrow, which, as Mr. Scott has pointed out (1), 

 these pupse possess to a remarkable degree, appears to be due to 

 the serrate structure of the abdominal rings.
