1876.] 263 [Scudder. 



docked at the tip, smooth, luteous, with the inner half, or nearly as 

 much, obscured more or less heavily with fuseous. Wings wanting. 

 Legs uniform luteous. Abdomen dark mahogany brown, sometimes 

 varying to black, with the sides of the second and third segments 

 blackish, the lateral plications of the third segment rather prominent, 

 all the segments but the last finely punctate, the last as F. californica 

 is described by Dohrn. Forceps of female rather more than half as 

 long as the abdomen, simple, slender, attingent, straight to the in- 

 curved tip, the inner edge quite straight to the tip, minutely dentic- 

 ulate; those of male about three-quarters as long as the abdomen, 

 the basal fourth moderately stout, triquetral, distant, directed slightly 

 outward and bent at the very base downward, the remainder bent 

 inward, but continuing the downward direction until near the hori- 

 zontal tip, cylindrical, slender, nearly equal, until a little beyond the 

 middle of the outer half, where at the emission of an inner rather 

 stout tooth, it tapers to a fine point, begins an inward curve and 

 takes on the horizontal direction; the inner side is edged, at base 

 laminate, and rather finely denticulato-tuberculate. Pygidium of ? 

 stout, bluntly trifid, of <S very slender, acicular, half as long as the 

 last segment. Length of body, 10.75 mm.; of antennae, 7.5 mm.; of 

 tegmina, 3.1 mm.; of hind femora, 2.8 mm.; of forceps, d, 5 mm., 

 ?, 3.5 mm. 3 d", 5 ? from jST* York (Coll. Uhler), Northern Illinois 

 (Kennicott), Southern Michigan (Prof. M. Miles, No. 124). A single 

 specimen is marked Cuba ? 



This species is closely allied to F. californica Dohrn, judging from 

 the description, but differs from it in the total want of wings, and the 

 structure of the male forceps. It appears also to be nearly allied to 

 F. pulchella Serv., a species I do not know, but the absence of wings 

 in our species prevents its reference to it. F. pulchella is possibly a 

 Labia. 



59. Labia rotundata. Head dark mahogany brown, darkest 

 below, but the labrum lighter, uniformly and slightly tumid ; palpi 

 reddish brown, darkest on the apical half; antennas more than 10- 

 jointed, the basal joint reddish brown, beyond a little duskier, the 

 whole briefly pilose. Pronotum nearly as broad as the head, reddish 

 luteous, paler at the sides, scarcely longer than broad, the posterior 

 angles very broadly rounded, but the hind margin otherwise straight; 

 it is depressed excepting in the middle of the front half, on which is 

 a finely impressed median line; lateral edges almost marginate. 

 Tegmina about half as long again as the pronotum, dull brownish
