The animal has the head considerably produced, and 

 anteriorly depressed, having the frontal margin rounded. 

 The eye appears to stand upon a process of the head, 

 between and above the superior antennee, but not to be 

 in connection with the projected hood-like process. It 

 is of a dull red-purple colour, but without a clearly-de- 

 fined outline, a circumstance that has led to the selection 

 of the specific name, as it has every appearance of being 

 an imperfect organ of vision. The antenna) are nearly of 

 equal length ; the superior are scarcely longer than the 

 head, — they have the first two joints of the peduncle
