THE PsELAPHID2 OF NorTH AMERICA. 79 
segment is shorter than any one of the succeeding segments, 
and bears on each side of the middle a transverse pubescent

Habitat. Middle California. 
F. parvicers, Mekiin. Dark brown. Length 2 mm. 
ffead wider than long, much smaller than in any of the pre- 
ceding species; the frontal impression is more transverse, 
the fovez not so well impressed and situated in a line with the 
anterior limits of the eyes, tempora arcuate. Antenne longer 
than the head and prothorax, the basal joint longer than in the 
preceding species, the ninth and tenth joints transverse. 
Prothorax widest behind the middle; the fovee before the

basal impression. /ytra with the sides straight, divergent, 
half as long again as the prothorax, shoulders not prominent. 
Abdomen with the sides divergent, the first segment apparently 
half as long as the second. In the living specimen this pro-

Habitat. British Columbia. 
This description is taken from a drawing made thirty years

the width of the first; third smallest, as long as wide; fourth 
to sixth little longer than wide, one-half wider than the third; 
seventh to tenth gradually wider, not longer, the tenth being
