plate covers the ventral side and extends far enough to be seen from 

 above on the sides and in front. Fig. lo. These hard plates are 

 rough and covered like the softer areas with fine scattered hairs. 

 The sternum is hard and rough and extends upward between the legs 

 as it does in L. crenatum. 



One male only from Danbury, Conn., July 19, 1912. 



Tmeticus multidentatus. new 



This species resembles T. tridentatus and T. trilobatus, but is smaller 

 than either, measuring little over 1.5 mm. in length. The mandibles 

 are strongly toothed on the front with one large tooth on the inner 

 side and a row of five on the outer side, the lower one very small and 

 the one next above the largest of the row. Fig. i. The male palpi 

 are long as in the related species. The patella has a slight spur on the 

 under side at the end. The tibia is much widened and covers the 

 base of the tarsus above and below and the upper projection has a 

 complicated and characteristic shape consisting of a rounded lobe 

 divided by a middle ridge around which it is partly folded. Figs, i, 

 I a, lb. PI. II.

Tmeticus thoracicus. new 



1.5 mm. long, legs and palpi pale, cephalothorax and abdomen both 

 dark gray without markings. Cephalothorax wide behind and

 and much widened toward the end. On the upper side the tibia 

 extends in a long point over the tarsus and on the inner side is a shorter 

 point less than half as long. The mandibles have no tooth on the 

 front. Figs. 2, 2 a, 2b. PI. II.
