markedly inwards ; anterior lateral hairs slightly shorter and somewhat stouter than 

 the superior hairs ; interlamellar hairs similar to superior hairs but smaller. Pseudo- 

 stigmatic organ fusiform, about as long as the tarsus of leg I, serrate and very 



slightly curved. 



Abdomen subglobose ; pteromorpha: large and projecting forwards beyond the 

 middle of the cephalothorax, the anterior free edge appearing rounded from above ; 

 in ventral aspect the anterior edge of the pteromorpha; is emarginate. Abdomen 



hairless. 



Legs short ; anterior pair about two thirds as long as abdomen ; tibia and tarsus 

 of leg I subequal. The legs are clothed with many simple bristles, also with a few 

 short, stout, curved, pectinate bristles, which are situated on the inner side. Ungues 

 large, tridactyle ; dactyles equal. 



Length, 0.78 mm.; breadth, 0.62 mm. 



Under a large stone. Collected by the writer at Batavia, 111. Two 

 specimens. 

 Oribata macroptera, new species. (Plate II, Fig. 7.) 



Body dark reddish brown ; wings and legs light brown. 



No true laraellffi present but a pair of lateral lamellte closely appressed to sides 

 of cephalothorax. Superior bristles straight, pectinate, about one half as long as the 

 cephalothorax ; antero-lateral bristles about as long as the superior bristles, curved as 

 usual but apparently simple. Pseudostigmatic organ subfusiform, recurved, pectinate, 

 about as long as tibia of leg I. 



Abdomen broadly rounded posteriorly ; anterior one half of lateral margin, where 

 the pteromorphffi are attached, straight. Pteromorphse large, broad, extending almost 

 to the tip of the cephalothorax, rounded anteriorly, posterior dorsal margin notched. 

 Abdomen hairless. Genital covers about three fifths as long as the anal covers and 

 situated twice their length in front of the latter; anal covers situated about one third 

 their length from the posterior margin of the ventral plate. 



Anterior pair of legs as long as the body ; tarsus one and one half times as long 

 as the tibia ; genual almost equal to the tibia in length. Ungues tridactyle ; dactyles 

 unequal. 



Length, 0.56 mm. ; breadth, 0.39 mm. 



In sweepings from grass. Collected by C. A. Hart at Brownsville, 

 Tex. Several specimens. 



This species is related to O. texana Banks and O. depressa Banks 

 but differs from the former in the length of the anterior pair of legs 

 and in the shape of the pseudostigmatic organs and from the latter in 

 the size of the wings and in the width of the body. 



Oribata rugosala, new species. (Plate III, Fig. 8.) 



Chestnut brown ; integument of abdomen smooth, of wings wrinkled (hence the 

 name, ru^osa, wrinkled + a/a, wing). 



Cephalothorax short and broad ; no lamellae or translamella ; antero-lateral hairs 

 curved and pectinate as usual. There is a single pair of hairs upon the dorsal surface
