440 Dr. R. J. Tillyard on 



study. So far, however, nothing more has been added to 

 our knowledge of these wonderful little moths. I have, 

 therefore, decided to pubhsh the results to date, and hope 

 that the life-history may be completed later by the dis- 

 covery of the eggs, early larval stages, and living pupa. 



Description of the Larva of Sabatinea barbarica Phil]). 



(Plate XXXIV, Text-figure 1.) 



Total length of the well-grown larva (probably full-fed) with head 

 retracted, 40 mm. Greatest breadth, across 4th and 5th abdominal 

 segments, 2-0 mm. Width of transverse pouch into which head is 

 retracted, 0-4 mm. 



General shape broadly oval, widest at 4th and 5tli abdominal 

 segments. In transverse section across any body segment, the 

 shape is hexagonal (Text-fig. 1, g), the six sides of the hexagon being 

 of approximately equal length. The ventral side is flattened, the 

 two latero-ventral sides slightly convex, but the two latero-dorsal 

 sides and the dorsal side itself are all definitely concave, the large 

 specialised macrotrichia (dolichasters) projecting from their angles. 

 The dorsal part of the 4th abdominal segment is narrowed and 

 darkened, so that the larva appears to be divided by this con- 

 striction into two approximately equal and similar halves fore and 

 aft from this segment, and it is not easy to tell the head end from 

 the anal end when the head is retracted. The back of the larva 

 is raised up as a high convex ridge on either side, so that the lateral 

 view is greatlj^ arched, as shown in Plate XXXIV, fig. 3. 



General colour creamy whitish, with very complicated markings 

 of pale and dark gi-eenish brown. The dark markings are confined 

 for the most part to the latero-dorsal sides of the abdominal segments 

 and across the dorsal side of the 4th abdominal segment. The 

 concave dorsal side, between the two high ridges, is for the most 

 part (except on segment 4) irregularly mottled with paler olive 

 green, as shown in Plate XXXIV, fig. 1. The latero-dorsal sides of 

 abdominal segments 2-7 show a delicate whitish line dividing the 

 dark area on each, with signs of very fine transverse whitish ribs 

 projecting from it on either side. The latero-ventral and ventral 

 sides are pale creamy, except on the thorax, which is slightly 

 darkened. 



Head very small, completely retractile into a pouch or pocket 

 of the prothorax. When everted, it is pale in colour, except the 

 mandibles and maxillae, which are dark brownish. The tentorial
