segment proximally with some short stont spinelike bristles. The lateral tubercle 

 of the prothorax of the larva is mnch prolonged. 



The species are miicli less numerous than in Subsection A. Though some of 

 the species are more nearly related with one another than with the other members 

 of the Subsection, the differences in structure are very slight. It appears to us, 

 therefore, advisable to keep all the species united in one grou]), by which means 

 the close relationship between them will be best emphasised. In the key the 

 species are grouped according to relationship.
