Div. II. 



Pseudostigmatic organ very long, filiform D. n'gidiis sp. nov. 



Pseudostigmatic organ short, subcapitate D. inagnipilosiis sp. nov. 



Dameeus rigidus, new species. (Plate V, Fig. 28. ) 



Reddish brown. 



Cephalothorax three fifths as long as the abdomen ; broadest above the attach- 

 ment of the anterior pair of legs. Superior bristles small, straight, less than one third 

 as long as the cephalothorax ; antero-lateral bristles slightly larger than the superior 

 bristles, markedly curved and pectinate on the outer margin. Pseudostigmatic organ 

 very large, long and bristle-like, pectinate, about equal to the cephalothorax in 

 length. 



Abdomen oval, smooth and polished. Dorsum with a submedian row of four 

 curved, minutely pectinate bristles on each side and also with two pairs of bristles 

 situated laterally and a row of six very small, almost straight bristles around the pos- 

 terior margin, the inner pair being the largest. 



Anterior pair of legs as long as the body. Tarsus of leg I longer than the tibia ; 

 genual scarcely one half as long as the tibia. All the legs moniliform. Coxa of leg 

 III much swollen. All the legs bear several stout, curved, pectinate bristles ; tibiae 

 of legs I and II each have a distal, tactile hair about as long as the segment itself. 



Length, 0.46 mm.; breadth, 0.26 mm. 



In moss. Collected by L. M. Smith at Parker, 111. Several 

 specimens. 



Damaeus magnipilosus, new species. (Plate V, Fig. 29.) 



Olive brown ; surface of integument slightly rough. 



Cephalothorax slightly longer than broad ; two pairs of rostral hairs present, the 

 anterior pair being about two thirds as long as the posterior pair, and posterior pair 

 about three fifths as long as the femur of leg I ; two pairs of larger bristles are situ- 

 ated on the dorso-vertex close to the pseudostigmata ; one pair just inwards to the 

 same and the other pair just lateral to the pseudostigmata. Pseudostigmata cylindri- 

 cal but low ; pseudostigmatic organs rather small, almost erect, with small peduncle 

 and globose head. 



Abdomen oval, three fifths as broad as long ; dorsum clothed with about two 

 dozen large, curved, simple bristles, those on the posterior part smaller than those on 

 the anterior part. At the posterior margin of the abdomen are situated two pairs of 

 short, stout, fusiform bristles, characteristic of this species ; the upper two are about 

 twice as long as the lower two, and both pairs are inclined away from the median 

 plane. Ventral plate shield-shaped ; genital covers contiguous with the anterior 

 margin of the ventral plate, each being about twice as long as broad ; anal covers 

 larger than genital covers and situated about their length from the latter, and about 

 one third their length from the posterior margin of the ventral plate. 



Anterior pair of legs about as long as the entire body of the mite. In this species 

 the segments of the legs are not swollen so much as in other species of the same 

 genus. The femur of leg I is about equal to the cephalothorax in length ; tarsus
