group, filled with coarse, rather close rugse, those at apex transverse; posterior 

 face of middle segment very coarsely rugoso-reticulate, divided by a median 

 sulcus, sides of middle segment with some coarse folds, nearly smooth at base; 

 legs reddish testaceous; veins of wings testaceous. 



Massachusetts. The only specimen I have seen of this species is 

 the type, which unfortunately lacks the abdomen. Packard de- 

 scribes this as follows : " Body of the abdomen longer than the head 

 and thorax together, being unusually long and slender, ovate lan- 

 ceolate, pedicel nearly as long as abdomen is wide, grooved deeply 

 laterally, highly polished ; abdomen with the rings slightly coarc- 

 tate, sutures well impressed, hind edge of second, third and fourth 

 rings obscurely and narrowly blood-red ; tip acute, with a narrow, 

 long, subtriangular, well-marked, flattened surface. Length of the 

 body .36." 



F. fuscipes is placed in this group provisionally. In the subtile 



punctuation of head and dorsulum it is isolate from the other species 



of the group. The examination of perfect specimens may show 



differences requiring the relegation of this species to another group. 



4. Group monticola. 



Pygidium ( $ ) broad, not greatly narrowed apically or much de- 

 pressed, margined laterally and with large punctures. Petiole above 

 at most indistinctly sulcate near the sides, on the sides themselves 

 not deeply sulcate. Second recurrent vein received by the third 

 submarginal cell, the first recurrent by the second cell. Cubital vein 

 of hind wings originating distinctly before the apex of submediau 

 cell. Antennie ( S ) elongate, slender. Front with a slender carina. 

 Tibise spinose, 



14. Psen monticola Pack. 



Mimesa monticola Packard, 1. c, 407, % . 

 9- — Head finely punctured, closest on front; face and clypeus with tolerably 

 dense silvery pubescence; anterior margin of clypeus squarely produced in the 

 middle and subtruncate; space between hind ocelli slightly less than that be- 

 tween them and eyes, not connected by a furrow; flagellum testaceous beneath, 

 clavate; mandibles yellowish medially; dorsulum with tolerably strong, separated 

 punctures, shining, not striated ; mesopleurae less strongly punctured ; enclosure 

 of middle segment large, with strong rugas the medial area reduced to a furrow, 

 which is broadened apically ; posterior face of middle segment deeply sulcate 

 down the middle, rugoso-reticulate, but not very coarsely, clothed with silvery 

 pubescence, as are also the mesopleurse, pronotum and cheeks; tips of femora, 

 tibiae and tarsi entirely fulvous, sometimes the femora and trochanters also; 

 abdomen red, petiole black; pygidium broad and flat, with large, spai-se punc- 

 tures; petiole at most as long as hind femur and trochanter, above indistinctly 

 sulcate near sides, at apex widened and depressed ; wiiigs clear, second submar- 

 ginal cell subquadrate, narrowed barely one-third above, and receiving the first 

 recurrent nervure between base and middle,! third submarginal receiving the 

 second recurrent vein near base. Length 9-10 mm.
