 length (PI. XXIV, Fig. 15) ; mandible brown at apex, central tooth on 

 inner surface poorly developed; labium as in Figure 6, Plate XXV; 

 labial papillse as in Figure 9, Plate XXV ; maxillary palpus as in Fig-

 with pale brown claws ; dorsal respiratory organs stout, with two dis- 

 tinct hairs just above their bases ; dorsal tuft with about twenty long 

 sensory hairs, the basal papillae about twice as long as thick, dorsal 

 view of anal segments as in Figure 15, Plate XXVI. 



Pupa. — Length, 5-6 mm. Reddish, becoming brownish as the 

 time for emergence of the adult approaches. Respiratory organ as in 

 Figure 4, Plate XXVII (part of the trachea shown) ; a short trans- 

 verse row of minute tubercles extending from near the base of each 

 respiratory organ towards the mesial line. Slightly beyond the mid- 

 dle of the lateral margin on each segment there is a small wartlike pro- 

 tuberance armed with hairs as shown in Figure 6, Plate XXVI ; lat- 

 eral margin of penultimate segment with eight long lanceolate hairs, 

 serially arranged on the apical four-fifths; last segment with a patch
