C. latifasciatum Piaget (Suj^plement, p. 130, pi. xiv, fig. 

 2), from Rhynchops fiavirostris . The difference in size,

 inal segments, together with the unrelated host leads 

 us to make the specimen the type of a new species. 



Description of female. Body, length 1.84 mm., width 

 .67 mm.; golden brown, with ill-defined, median, trans-

 markings. 



Head, length .35 mm., width .54 mm.; broadly and 

 flatly rounded in front, with numerous, rather long, and 

 a few short, marginal hairs; one very long marginal 

 hair just in front of the ocular emargination, and two 

 shorter hairs directly on the angle; ocular emargina-

 prominent, emarginated, with a large ocular fleck; 

 ocular fringe distinct; antennae with last segment 

 broad, extending beyond the head; temples with ante- 

 rior angles rounding, posterior angles angularly meet- 

 ing the occipital margin; three very long and some 

 shorter hairs on the temporal margin; the occiput 

 slightly concave, with four rather long marginal hairs; 

 a narrow, curving, fuscous band running parallel with 

 the clypeal margin, ending at the lateral extremities in 

 a dark chestnut spot; distinct, black, irregular, ocular 

 blotch; triangular bases of occipital bands blackish 

 brown, connected by an even, occipital border, narrow- 

 ing medially. 



Prothorax broad, lateral angles acute, bearing one 

 long hair and a short spine, sides converging poste- 

 riorly, with one long hair in the posterior angles; a 

 series of long hairs on the posterior margin. Meso-
