the top of the mesothorax curving down to this point ; the ventral 

 line (of maxilla from horn to end) would be nearest this axis 

 opposite mesothorax, receding from it both forwards and backwards, 

 or, in other words, a straight line from base of maxilla-horn to the 

 most prominent point over middle of 4th abdominal, would have 

 the pupal surface imm. distant from it opposite metathorax and 

 o'5mm. at end of wings. 



Of other irregularities, the dorsal line sinks a little at 

 metathorax, and, laterally from this, a hollow deepens, till it 

 becomes nearly 2mm. below the level of a continuous surface, 

 just where the hindwings cross the ist abdominal segment, and con- 

 tinues as a slight hollow into the forewings. The prothorax has also a 

 triangular hollow in front of the ist spiracle so that the rest of it, seen 

 dorsally, looks like a square piece marked off 3 , 5mm. long x 

 7mm. wide. The glazed eye is a rather broad crescent of smooth 

 polished surface, without very definite alteration of the areas about it, its 

 convexity points about 20 ventral of anteriorly. Really the great rounded 

 cheeks, forming a large boss on either side in front of the glazed eye, 

 look more like the eyes, and are no doubt provided to afford space for 

 the development of the imaginal eyes. The ends of the ist tibiae afford very 

 decided elevations, and the 2nd leg is separated from the head by about 

 3mm. Sculpturing : The labrum is not very clearly marked off from the 

 front, and has a small tubercle or two towards its margin. The head 

 is finely wrinkled especially on the prominences, but its general 

 effect is of being polished. The maxilla-horn has a fine double 

 ridge at suture, and is transversely ribbed, the ridges are closer 

 basally, where most prominent, they are about two to a millimetre 

 and each of these double, as if corresponding to actual maxillary
