Tilt' Hpociinens colltH^ttHl by me in tlie middle of April measured 

 10 mm. I did not succeetl in cultivating them, therefore I do nut 

 know to which instar they belonged. The arrangement of the 

 setae of theue specimens is the same as of those of coll. Kall. 

 The full-grown specimens are 35 mm. 



Prothoi'djr. S. dot-inilis, s. suhdorsalisj .s. prostiyimdis^ two ». basales 

 on one tuberculum, .<«. proprdaliSy «. postpedalis. 



Mesothorar and Metathorojc. S. dormlis^ a. dorsoldtendis, 8. supra- 

 ittigmalis, s. prostitjtnidis and on the place of tlic wing-rudiment 

 one seta. One might be tempteil to look for the rudimentary 

 stigma on this spot, as in this place the air-tubes arise from the 

 main trachea. Two s, basaUs^ s. propedalus^ 8. postpedalis.

Instar /. Length 6 — 7 mm. The head is black, the tubercula 

 are brown, they soon begin to colour. The tubercula are warts, 

 the setae are plumed. 



Prothorax. There is no prothoracic shield, but the two v. dorsales 

 of the left and right sides approach one another and they have
