acuminated, the fourth is large and deeply bilobed, the fifth 

 middling, thin, the claws simple. The tarsi are altogether short 

 and strong, the first joint is furnished with longer, the second 

 and third with shorter stiff hair, whilst the fourth is strongly 

 penicillated below. The anterior tibiae are slightly spinose, 

 the others more so. 



The legs in all my specimens are exactly the same, and I 

 hardly know whether they are males or females. The insect 

 has a peculiar, rather strong smell about it, resembling that 

 of soap.

This diagnosis may appear somewhat vague, still I have 

 been unable to express the characteristics of the insects from 

 which it is drawn in more precise terms, although they have 

 features quite peculiar to themselves by which they are easily 

 recognised when once seen.
