Pale yellowish, edges of the lamella, edges of the square 
at base of cephalo thorax, and the edges sloping back from 
each side dark brown; legs pale, almost hyaline. The 
cephalothorax is nearly as broad at base as long, the 
line of separation from abdomen crosses just above the 
square, a fainter line crosses the square. The square is 
partly open in front to a slender triangle which separates 
the bases of the broad lamellae, which, beyond this tri- 
angle, appear united into one and extend to near tip of 
the cephalothorax, where there are two points near each 
other and each tipped by a short spine, the outer edge of 
each lamella is dark, at first slightly, evenly outcurved 
until halfway to the tip of cephalothorax and here the 
dark margin separates and projects forward in a slender, 
very sharp spine. Each side, a little lower down, is a 
lateral plate or lamella, nearly hyaline, about two-thirds 
the length of cephalothorax, and with a nipple-like tip, 
this may be the lateral part of the principal lamella, and 
the dark ridge, ending in a long spine, may be a ridge 
across the lamella. 
Each side of this lower lamella is seen the edge of the 
tectopedium, this is very long. The submedian bristles 
are thick, slightly roughened, very long, with a slender 
pointed tip, and arise from just in front of the clear 
triangle which separates the lamellae at base ; the superior 
bristle is a very fine and extremely long hair, arising just 
in front of each anterior corner of the square; the seta 
is long, curves forward much as in 0. plummeri, is thick- 
ened only near end which is roughened. 
The abdomen is plainly longer than broad, the sides but 
little curved; the wing does not extend in front of the 
abdomen, is not very broad, and behind merges gradually 
into the outline of abdomen. On the venter the genital
