the anterior spinnerets. The calamistrum consists of seven or eight 

 pairs of hairs about the diameter of the leg in length, Fig. 2c. The 

 coxae of the fourth legs are more than their diameter apart, and the 

 end of the sternum extends backward beyond them in a blunt point, 

 Fig. 2d. The epigynum shows externally two round spermathecae, 

 each crossed by an opaque spot, and in some specimens spiral tubes 

 can he seen connecting with them. The male palpi resemble those 

 of Dictyna. The tube of the palpal organ coils around the edge 

 of the tarsus, where it is supported by a wide thin appendage ; it 

 curves around the base of the tarsus to the upper end, where it is 

 twisted and rests against a blunt process of the tibia. 



These little spiders live under leaves and are found by sifting in 

 company with various Frigoneae. They have been fond in various 

 places around New Haven Connecticut and at Three mile Island, 

 Lake Winnipesaukee, and Fitzwilliam, N. II. 



Amaurobius borealis, new. (Plate VIII, figures 3 to 3d.) 



Female 5 mm. and male 4 mm. long. The cephalothorax and 

 legs are yellow brown, the legs darker toward the tips and the 

 cephalothorax darker around the edges, but little toward the head. 

 The abdomen is reddish brown with an indistinct pattern. The 

 cribellum is small, not wider than the length of the first spinnerets 

 anil is indistinctly divided in the middle. It is on a slight elevation 

 just back of the spiracle. The calamistrum occupies half the length 

 of the metatarsus. The epigynum has a wide middle lobe, covered 

 at the ends by the lateral lobes. The male palpus has the patella 

 as wide as long, with one stout spine projecting over the tibia. The 

 tibia is curved and has the usual complications shown in the figures. 

 Fitzwilliam, N. H., abundant near the Rhododendrons. Portland, 

 Me., under leaves on the ground. Mature in May ; females with 

 eggs in July.

Micaria laticeps, new. (Plate X, figures 4 to 4 c.) 



One male of this species was found under a stone at New Haven, 

 Conn. The length is 3 mm. The cephalothorax is a little higher 

 than in the other species, and the head nearly as wide as the widest 

 part of the thorax. The eyes of the upper row are at equal dis-
