The cephalothorax is shaped as in quinquenotata, a little narrowed 

 in front and not much elongated. In some individuals the cephalo- 

 thorax is unusually narrowed behind, so that the widest part is in 

 front of the middle. The cephalothorax is a little less than 2 mm. 

 long. The abdomen is oval without any constriction in the middle, 

 sometimes in females twice as long as it is wide, in males not 

 much longer than the cephalothorax. 



The color of the cephalothorax varies from light brown to black, 

 covered with light shining hairs not very close together. The first 

 and second legs have the femora dark like the cephalothorax, and 

 the other joints light yellow. The third and fourth legs are brown, 

 the femora darker. The sternum is dark brown and the front coxae 

 are the same color ; the other coxae are partly light colored ; the 

 fourth pair almost entirely light yellow. The abdomen is covered 

 with dark green iridescent scales, with a narrow white band across 

 tho middle, and in some individuals another transverse white band 

 near the front end, but this is oftener broken into two short white 

 streaks at the side. 



The epigynum has a large opening in front, covered by a wide 

 rim with a dark colored edge, Fig. 3d. 



The male palpi have no process on the tibia. The palpal organ 

 is flatter than it is in longipcs and quinquenotata, but has a hook 

 in the middle as in those species.

This small species has the general appearance of a Micaria. It 

 measures 6 mm. in length, the cephalothorax nearly 3 mm. The 

 cephalothorax is twice as long as wide, widest in the middle and 

 narrower behind than in front. It is slightly indented at the sides 

 between the second and third, and between the third and fourth 

 legs, Fig. 5. The head is three-fourths as wide as the thorax, 

 wider than in the other species, and the eyes are farther apart. 

 The upper eyes are equidistant and cover three-fifths of the width 

 of the head. The sternum is narrowed and pointed behind, more 

 than it is in the other species. The abdomen is a little longer than 

 the cephalothorax, widest behind and a little constricted in the 

 middle. The pedicel is as long as wide and can be seen from 

 above between cephalothorax and abdomen. 



The color of the cephalothorax is dull orange as in Micaria lougipcs. 

 The femora are marked with two longitudinal dark stripes as in 

 M. lougipcs and C. bivittata. The other joints of the legs are orange
