44 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 89 



by H. F. Loomis. A i /-segmented female was collected from the 

 same locality, March 21, 1930, by O. F. Cook. Two females were 

 collected within the Citadel, Cape Haitien, Haiti, March 27, 1932. 



Description. — Length of the largest specimen, a female, 5.5 mm, 

 width .8 mm. 



Living color definitely pink. 



Head with the three teeth of the labrum small but acute ; the surface 

 of the labrum and clypeus less hirsute and more distinctly shining 

 than the rest of the head ; antennae as shown in figure 21, a. 



Behind segment 4 the seta at each end of the posterior row is usu- 

 ally reduced in size or is entirely lacking, leaving only the four inner 

 setae. On the poriferous segments a small seta rises from the top of 

 the posterior projection of the lateral margin of each carina above and 

 just behind the pore. The entire dorsal surface of all the segments

is rather coarsely reticulated as seen with high magnification, with 

 the bottom of each cell strongly shining. 



Gonopods with each basal joint large and strongly convex, sub- 

 triangular, hollowed and apparently capable of receiving the outer 

 joint when retracted. In the type these outer joints are projected 

 laterally, one crossing the other and hiding much of it. Each outer 

 joint is moderately stout, evenly curved, with a very large, acutely 

 triangular lobe at the middle of the inner side ; outer portion of the 

 joint more slender, subspatulate, the apex rather thin and rather 

 broadly emarginate (fig. 21, b). 



The two females collected in Christoph's Citadel, are each 8 mm 

 long, and although considerably larger than the specimens from the 

 type locality, they agree very well in other particulars ; however, exami- 

 nation of males from near the Citadel might show that they repre- 

 sented a second species.
