Tarsonemus pallidus Banks (?) 



Female. — Body pale yellowish-brown, capitulum darker. Total length of the body 

 about twice that of its greatest width. Capitulum large, extending forward to about 

 the middle of tarsus of leg I. Pseudostigmatic, or sense, organs dorso-lateral, with 

 spherical heads and very short pedicels, which arise from prominent circular pores. 

 Just lateral to each sense organ is situated a very long tactile seta, which surpas.ses by 

 fuUy a third of its length leg II, near which it is also situated. Abdomen more or 

 less pointed posteriorly, and bearing along its po.sterior margin three pairs of small, 

 inconspicuous setae. Anterior pair of legs stout; second pair sUghtly smaller; third 

 pair extending beyond the margin of abdomen by the full length of the tarsus and one- 

 half the length of the tibia. Posterior legs reaching the tip of abdomen ; tarsus almost 

 two-thirds as long as the tibia, and bearing at its tip a very long terminal seta, as long 

 as the total length of leg IV; a short distance from its tip, on the outside, the tarsus 

 bears a somewhat stouter seta, a little over a third as long as the terminal one. 

 Length, 0.21 mm.; width, 0.12 mm. 



Male. — Body stout, legs short. Capitulum reaching the tips of anterior legs. 

 Lateral spine at junction of cephalothorax with abdomen about one-half as long as 

 leg II. Leg IV very characteristic, segment II about two-thirds as long as the entire 

 leg, curved, with a large, hyaline, blade-like expansion on the inside which is almost as 

 broad as the segment proper and extends for about the distal two-thirds of the seg- 

 ment; below near its tip segment II bears a long seta. Segment III of leg IV short, 

 much curved, bearing below near its tip a very long seta, which is equal in length to the 

 entire leg; on the outside there is a short seta, and a more or less spine-like one on the 

 inside at the tip. Distal claw long, curved, but tip not sharpened. Length, 0.13 mm. 

 width, 0.09 mm. 



From Corvallis, Oregon; on cyclamen; by G. F. Moznette. De- 

 scribed from several specimens. According to Mr. Moznette this 

 species causes serious injury to the cyclamen plant. 



Monieziella hipunctata n. sp. 



Alcoholic specimens pale yellowish, with the lateral abdominal maculations a 

 chestnut brown. Chelicerae large, stout. Cephalothorax more or less triangular in 

 shape; anterior bristles prominent, slightly surpassing the mandibles; posterior 

 bristles equal to about one-half the total length of the body, and each situated about 

 one-haK the distance from the median line to the lateral margin of the body. Abdo- 

 men separated from the cephalothorax by a transverse almost straight line. Shoulder 

 bristles small, incc)nspicuous. At its tip the abdomen bears a pair of very long setae. 

 They are about as long as the width of the abdomen itself. Legs moderate ; anterior 

 pair extending beyond the tips of the chelicerae by about a third of their length. 

 Tarsus of leg I about twice as long as the tibia with a rather stout seta above about 

 one-third the length of the segment from its base, a slender tactile seta above near 

 tip, and a rather long seta ventrally near the base. Length, 0.22 mm.; width, 0.12 

 mm. 



From Oregon; on base of buds of filbert; by A. L. Lovett. Many 

 specimens.
