Cephalothorax broader than long. The lamellae and trans- 

 lamella consist each of a narrow blade on edge; translamella 

 slightly narrower than the lamellae and continuous with them, 

 the whole being sublimate; lamellar hairs as long as the ceph- 

 alothorax, straight and pectinate; rostral hairs stout, curved, 

 and pectinate, a little longer than the pseudostigmatic organ. 



Abdomen broader than long, with a few small hairs; ptero- 

 morphse very long and prominent, projecting beyond the tip of 

 the rostrum, rounded in front and pointed behind. Anal covers 

 three fifths as broad as long, and situated one half their length 

 from the posterior margin of the abdomen; genital covers 

 about two thirds as long as the anal covers, similar to them in 

 form, and situated about twice their length from the same. 



Legs subequal in length; hind pair slightly longest; tibia 

 and tarsus of leg I subequal. genual one half as long as the 

 tibia, femur a little longer than the genual. The femur of leg 

 II is very much enlarged, and is half as long again as the 

 femora of the two posterior legs. 



Length, 0.88 mm.; breadth, 0.62 mm. 



Collected by myself at Urbana, HI. Three specimens. Mr. 

 Banks has confirmed this determination from specimens sent 

 to him by the author. 



Oribata odopundata, n. sp. (PI. XXXIV., Fig. 7.) 



Light yellowish brown; integument thin. 



Cephalothorax broad; pseudostigmatic organ very long, re- 

 curved, with a thin peduncle and a much enlarged, pectinate, sub- 

 cylindrical head; interlamellar hairs straight, pectinate, short, 

 and inclined toward the median plane, but projecting very little 

 forward; rostral hairs similar to the lamellar hairs but curved. 



Abdomen broad, hairless, with a longitudinal row of four 

 small, oval dark spots on each side, the anterior spots 

 being much the largest; a few similar but very minute 

 spots on the dorsum also. Pteromorphee free, projecting 

 almost to the tip of the rostrum; both the anal and genital 

 covers situated about their length anterior to the anal covers. 



Length, 0.54 mm.; breadth, 0.40 mm.
