Hab. Fairfax, Marin Co., California, June. 



Mr. Nunenmacher stated that he obtained the specimens 

 while digging in a ledge near a spring. He did not state 

 whether they were taken in company with ants. He was col- 

 lecting Promecognathus l&vissimus at the time. 



At first glance, before examination, this species might be 

 mistaken for Bembidium rickseckeri, but it was lighter in color 

 and of slower movements ; at a casual glance it more resembles 

 Bembidium laticeps in form and color. 



The sexual characters are not very evident, the male is evi- 

 dently smaller and narrower. The metasternum is slightly 

 impressed at middle just in advance of the abdominal process. 



The first abdominal segment is equal in length to the fourth 

 and fifth taken together, and its post-coxal portion is equal to 

 the length of the third ; the second is a third longer than the 

 third. The tibial grooves of the femora are moderately w r ell 

 defined. The tarsal grooves of the tibiae are not evident. 

 The pro tarsi have the first and second joints when taken to- 

 gether about equal to the length of the fifth ; the first slightly 

 longer than the second, the third and the fourth are shorter 

 and not equal in length. In the mesotarsi, joints one and 

 two are subequal in 1-ength and together about as long as the 

 fifth ; the third and fourth taken together distinctly longer 

 than the second, the third is distinctly longer than the fourth. 

 The metatarsi have the first joint at least as long as the third 

 and fourth taken together, and about twice as long as the 

 second, the latter being about a third of its own length longer 

 than the third joint.
