NEW AMKUICAN ACARINA. 221 



Fii|>al|>ii»» ocliiiiatiis nov. sp. — Length .9 inin. Red; legs and month- 

 parts pnle, liairs hhick. Body oval, pointed in front, rounded behind, broadest 

 behind the middle: the mandibles are short, on a small neck, the palpi closely 

 appressed to their sides; first joint of palpus short, the second much longer, and 

 the third shorter tlian second. Body and legs covered with short, stift", thick 

 hairs, which are finely serrate on the edge; these hairs are from one-half as long 

 to nearly as long as the mandibles : there are about sixty of them on the dorsum, 

 and one on the second and one on the third joint of the palpi.

'i'he species of tliis family are very small, and I have not collected 

 them thoroughly. Dr. Riley has recorded a species of" Penthaleus 

 from Florida, but his description shows that it does not belong to 

 this family. In the shape of the various parts of the palpus are 

 found the characters for the separation of species. The three genera 

 known to me may be separated as below : 



1. — First pair of legs more than twice as long as body liiiiopocli'N. 



First pair of legs much shorter 2. 



2. — Hii;d femora mucli thickened, mandibles small Kii|>o<le<i«. 



Hind femora normal, mandibles very large Itlia;;i<li:i. 



■iiiiopodOK a II ((Mill a' pes nov. sp.— Length .6 mm. Reddish or yellow- 

 ish, sometimes with some pale marks; legs mostly yellowish, except distal half 

 of leg i, which is hyaline. Body oblong, rounded in front and behind ; broadest 

 at hind margin of cephalothorax ; cephalothorax semicircular, with a large 

 shining eye each side. A narrow, eniarginate. smooth band just behind cepha- 

 lothorax, which gives off a median projection reaching to the tip of the abdomen, 

 the whole forming a T. Dorsum of body with a few scattered hairs. Leg i 

 more than twice as long as body, femur i longer than body ; legs ii and iii slender, 

 not quite as long as body ; leg iv with femur enlarged. Mandibles short, form- 

 ing a little cone; i)alpi a little longer than mandibles, joints snbequal, the third 

 longest. It differs from the European L. motatorius in having tibia i nearly as 

 long as the metatarsus, and the tarsus i being divided into three or four joints. 

 The body of the male is a little more globose than that of the female. 



This lives on the ground, and is most common under pieces of 

 wood, bui-k, etc., that have been on the ground for some time. The 

 first pair of legs is used as feelers ; ordinarily, it walks slowly, but 

 when disturbed can move very rapidly to the rear.

Kiipodes variabilis nov. sp.— Length .3mm. Reddish: yellowish, or 

 sometimes greenish; legs ])ak'. Body oblong, broadest at base of abdomen; 

 cephalothorax semicircular: abdomen slightly tapering, but broadly rounded 

 behind; a large, elliptical, shining eye in each posterior angle of the cephalo-
