 first to eighth joints subequal, obconical, the first one-third as 

 long as the frontal margin and half as wide as long. The 

 eighth is nearl}' quadrate, ninth to eleventh gradually wider^ 

 ninth and tenth obconical, as long as the three preceding,

 together. Prothorax as broad and as long as the head,

 at the lateral basal anMes. Next to the margin on each side 

 is a large ovoid tumor. This gives the tip the appearance of 

 being bilobed. The second segment is depressed at the sides 

 of the base and in the middle is a deep, circular, punctured 

 fovea. The third is produced, emarginate laterall}', bilobed 

 in the middle at the base, transversely depressed; the fourth
