consisting of two parallel spines on conical bases, flattened 

 laterally and directed posteriorly (text-fig. 9, b, d). 



Female Pupa. — Length 17 mm., width 6 mm. at end of 

 6th abdominal segment, subcylindrical from 3rd to 6th 

 abdominal segment; from the 3rd it gradually tapers to 

 the head, fi'om the 6th it is more abruptly rounded to the 

 caudal end. Colour mahogany red (II), head parts and 

 thoracic segments liver-brown (XIV). 



Head concealed undei- prothorax, excessively rugose so as 

 to obscure the parts of which it is composed. Clypeus large, 

 paraclypeals and maxillary palpi distinct. Prothorax projected 

 over the head, ventral aspect with flat median crest, surface 

 of prothorax strongly rugose. Prothoracic leg-cases small, 

 consisting of a narrow median part ending in two hemi- 

 spherical clubs, directly posteriorly. Leg-cases not detached. 

 Meso- and metathorax with larger leg-cases, directed pos- 

 teriorly and extending the entire width of the segments 

 (text-fig. 9, F, G, i) . First abdominal segment narrow ; 

 succeeding segments increase in width till the 6th ; smooth, 

 shiny, finely striatulate transversely ; posterior declivities 

 punctulate, matte. Seventh segment longitudinally striate; 

 8th smooth, with small genital scar ; 9th and 10th finely 

 sulcate transversely. Dorsal aspect : thoracic segments 

 coarsely rugose, abdominal segments finely transversely striate, 

 abd. 3 to 6 with a short transverse row of minute spines, 

 directed anteriorly; 6 and 7 with a short transverse row of 

 spines directed posteriorly, which have become vestigial on 

 the 8th segment and are here represented by a median pair 

 of small spines only ; 9th segment unarmed ; 10th segment 

 with a cremaster apparatus consisting of a broad, transverse, 

 quadrate plate, appearing to be the fusion of four spines 

 directed ventrally (text-fig. 9, h, k).
