Female, length of carapace on median line, including 

 posterior hump 47.3. width of carapace, exclusive of spines, 

 :t2.1 mm. 



Male /if>/(>t//j>f j . - Carapace with the regions well delimited, 

 the branchial regions approaching each other, the cardiac 

 region small, the hepatic regions prominent, the intestinal 

 region prolonged backward in a stout, blunt process. The 

 more elevated portions are tuberculate : The principal 

 tubercles are, a pair in a transverse line on the anterior 

 gastric region : two, median, mesogastric : a number on the 

 cardiac region chiefly grouped on two conical elevations side 

 by side : a band of tubercles on the branchial region extending 

 from the inner angle obliquely backward to the lateral 

 margin : those on the surface of the intestinal region which 

 include five or six of the largest tubercles of all. These are 

 deeply pitted, as is also the broad, blunt end of the intestinal 

 prominence. Hepatic region trispinose ; the upper, marginal 

 spine projects directly outward, the submarginal, anterior 

 spine projects forward, while a subhepatic spine points 

 obliquely forward and is visible in dorsal view between the 

 other two spines. The anterolateral margin of the branchial 

 region is armed with short blunt spines and tubercles arranged 

 mostly in a double row. The postorbital spine is triangular, 

 acute, and is a little nearer the eye than it is to the hepatic 

 region. 



Rostrum cut nearly to its base into two long liat, gradually 

 tapering, acute, and slightly divergent spines ; the upper 

 sin-face is longitudinally concave in the middle, the outer 

 edges of the two horns are subparallel or slightly convergent, 

 inner edges fringed with long straight hair, lines of curled 

 hair above which are continued backward on the carapace. 



Kyes rather long, stout, enlarged at both ends, curved, 

 much as in Gamposcia retusa Latreille. 18 Kye sockets circular. 

 margin smooth except for a small tubercle below, on the 

 basal antennal joint. This joint is longer than wide, longi- 

 tudinally furrowed in the middle except at the distal end. 

 where it is armed with a strong spine pointing downward, 

 forward and slightly outward, and partially visible from 

 above. 



The anterior angles of the buccal cavity are produced in a 

 blunt tooth ; above and in front of these angles there is a 

 short spine. .Merus of outer maxilliped at its widest point 

 as \\ide as the ischium ; palpus coarse, articulated at the 

 inner angle of the merus.
