Chestnut brown; integument smooth. 



Cephalothorax large, one half as long as the entire body. 

 Lamella? very long and slender, almost as long as the entire body 

 and of almost the same width throughout; anterior two fifths of 

 lamellae free. There is only a slight indication of a trans- 

 lamella. Lamellar hairs straight, pectinate, about half as long as 

 the lamella? ; interlamellar hairs very large, as long as the entire 

 cephalothorax, pectinate, and situated at the posterior margin 

 of the latter; antero-lateral hairs straight, similar to lamellar 

 hairs but smaller. Pseudostigmata but slightly projecting, 

 funnel-shaped; pseudostigmatic organ long, filiform, pectinate. 



Abdomen globose, bearing on its postero-dorsal aspect two 

 pairs of large, straight bristles, and on its postero-ventral 

 aspect a transverse row of four subequal straight ones, about 

 half as long as the dorsal bristles. Genital covers semicir- 

 cular, situated slightly more than their length from the anal 

 covers; anal covers much larger than the genital covers, and 

 situated about a third their length from the posterior margin 

 of the ventral plate. 



Anterior pair of legs about as long as the entire body; 

 tarsus one and a half times as long as the tibia; tactile 

 bristle of tibia straight, as long as the tarsus. Claws of tarsi 

 with three unequal dactyles. 



Length, 0.90 mm.; breadth, 0.68 mm. 



In moss. Collected by L. M. Smith at Parker, III, and by 

 the writer at Areola, 111. My determination of this species has 

 been confirmed by a comparison of my specimens with a 

 mounted one of bipilis sent me by Michael.
