crease in number toward the end of the body, there being about 

 thirty-two on segment III and twenty-four on segments V and 

 VI. Segment VII has the median line devoid of spicules, each 

 side being provided with about seven arranged in a slightly 

 curved line. Segment VIII very small, inconspicuous, the 

 lateral angles of the caudal margin provided with a few weak 

 hairs and the dorsal surface with several tubercles. Ninth 

 segment bearing the hypopygium, the tergal plate small, ending 

 in two chitinized cylindrical lobes, sharp-pointed, the points 

 directed sharply dorsad. Sternites — Segments I and II pale, 

 unarmed, hidden by the leg-sheaths ; segments III to VII quite 

 as in the tergites, the third segment with an interrupted row of 

 spicules, about twelve in the middle and two larger ones on 

 either side ; in some specimens the row is complete and contains 

 thirty to thirty-two spicules. Segments IV to V with complete 

 rows of about twenty- four spicules; segment VI with a wavy, 

 somewhat broken row of about twenty spicules; segment VII 

 with about five feeble spicules on either side of the bare middle 

 line; ninth sternite broader at base than at tip; tip truncate 

 with the outer angles rounded with a very deep median split. 

 Pleiirites, non-chitinized, segments II to VII bearing spiracles, 

 these spiracles located just caudad of the false transverse 

 constriction and a little nearer to the sternites than the tergites. 



Young pupae, when alive, are very pale, the soft abdomen 

 being almost white, the chitinized anterior portion very pale 

 brown. Older pupae are much darker, the chitinized parts be- 

 coming black with a bronzy reflexion, the abdomen much paler, 

 of a dirty brownish-grey. The breathing horns are dark brown 

 on the apical half. Young pupag, in alcohol, are light yellowish 

 brown, abdomen clear yellow, the pleurites a little darker.
