396 J. H. Emerton, 



Microneta olivacea, Emerton. N. E. Therididae, Trans, Conn. Acad. 

 1882. 



The male is 2 mm. long, the cephalothorax 1 mm. The cephalo- 

 thorax is as wide as long and wider than the abdomen. In front it 

 extends forward slightly beyond the eyes and beyond the mandibles. 

 The eye area is a little elevated. PI. Ill, fig. 5, 5 b. The mandibles 

 are narrowed at the ends and have one very small tooth near the 

 inner angle. The male palpi are of the microneta type but unusually 

 large. The tarsus is angular and has a small spur at the base. 

 Figs. 5, 5 a. The tarsal hook is wide and flat with a tooth at the 

 end and a wider one at the angle. 



The female is as long as the male but has the cephalothorax a 

 fourth longer than wide. Fig. 5g. The color is lighter than in 

 the male and yellowish brow^n rather than gray. The cephalothorax 

 extends forward beyond the eyes farther than in the male and 

 projects distinctly beyond the mandibles. Fig. 5 c. The mandibles 

 are slightly curved forward at the ends as they are in the male, 

 but are not much narrowed, and the single tooth is large. Fig. 5f. 

 The palpi have the tarsus thickened in the middle so that it appears 

 like that of an immature male. Figs. 5d, 5h. The epigj'num is 

 folded and resembles that of other Microneta and Bathyphantes. 

 Figs. 5i, 5 k. 



The female was found by the late H. C. Britcher on Mt. Katahdin, 

 Me., in 1901, and has since been found with males on Grey lock 

 and Mt. Mansfield. 



Three females found with two males at Norcross, Me. June 30, 

 1910, resemble those from other places except that the palpi are 

 not swelled at the end. Fig. 5 e. The males agree with those from 

 other places. 



Bathyphantes theridiformis, new. 



Cephalothorax 1 mm. long. Whole body 2 mm. long in male 

 and 3 mm. in female. Color pale with gray markings resembling 

 Theridion sexpunctatum. The cephalothorax has a wide middle 

 dark stripe as wide in front as the e3'es and tapering slightly back- 

 ward. There is a dark line along the sides of the cephalothorax 

 nearly to the e3-es. The legs are slight!}- gray on the ends and 

 middle of each joint. The abdomen has on the back a dark mark 

 over the dorsal vessel and a series of pairs of irregular dark spots 

 more or less united with spots along the sides and with each other. 



On the under side the coxai and mouth parts are pale and the 

 sternum gray. The abdomen is gray, lighter in the middle, and
