Flagellum of antennae 

 jointed; head rounded. 



A much smaller species than the 

 preceding, from which it differs in 

 the lack of the projections under 

 the eyes. The abdominal seg- 

 ments are narrower in comparison with the thoracic than in the other 



terrestrial forms. 



Length 8 mm, breadth 4 mm. Color 

 variable, usually brownish with two 

 darker streaks along the median line. 



This species is said by Say to be "very 

 common under stones, wood etc. in 

 moist situations," but according to Har- 

 ger it occurs near the shore under rub- 

 bish. The only specimens taken by the 

 writer were found at Freeport L. L, in 

 April, where they were abundant on the 

 underside of boards above his'h water.
