is bent at a sharp angle, as in T. debilis. The outer edge of the 

 tarsus which is without hairs and separated from the rest by a 

 sharp ridge has a wide rounded lobe in front of the tarsal hook.

Tmeticus entomologicus, new. 



Only 1 mm. long and dull gray. The cephalothorax is one-fourth 

 longer than wide and the head low, and a little narrowed. The 

 front row of eyes is one-fourth shorter than the upper row, the 

 front eyes are close together and the middle eyes only half the 

 diameter of the lateral. The male palpi have the tibia elongated 

 on the upper side and truncate at the end. The tarsal hook is 

 curved in a half circle and simple in form. PI. Ill, fig. 3. The 

 tarsus is short and round and the palpal organ large with a short 

 tube and two large processes.

Tmeticus tenuipalpis, new. 



Males and females 3 mm. long. Abdomen high and round and 

 marked as in T. probatns with light spots in pairs. The legs and 

 palpi are long and slender. The general color is dull gray without 

 markings except the spots on the abdomen. The mandibles are 

 very large in both sexes. In the male the mandible has on the 

 front and outer side a row of five stout teeth, smallest toward the 

 head. PL III, figs. 4, 4 b. On the under and inner side are two 

 rows of long teeth, four in the outer and five in the inner row, 

 between which the claw is folded. Fig-. 4 a. The maxillee are long 

 and wide, with blunt teeth at the sides, extending beyond the 

 sternum. The trochanter has also a short tooth on the under side. 

 The male palpi are unusually slender and nearly twice as long as 

 the cephalothorax. The tibia is slightly widened at the end with 

 short teeth around it. The tarsus is more than twice as long as 

 wide and the palpal organ occupies only the basal half. The tarsal 

 hook is short and without any prominent points or hooks. Figs. 

 4 c, 4d. 



The female has the same rows of spines on the mandibles as 

 the male, but all much smaller. The epigynum is very simple.
