distribution of this species as follows: "Hudson's Bay (Smith) 

 to Virginia, westward to Mt. Hood, Oregon." From the above 

 distribution this species may be said to belong to the Boreal 

 and Transition Life zones. H. $. Smith records this species 

 from Glen, Sioux Co., Nebraska, which is in the Upper Sonor- 

 an Life zone. 



The clypeus sometimes has the tooth bidentate, in the 

 females however it is usually entire. The sculpture of all 

 the specimens before me is the same. The first abdominal 

 segment is not twice as long as the second, and is not strongly 

 nodose at the apex. 



Try poxy loo subfrigidum n. sp. 



Male Length. 5 mm. ; very slender. Anterior margin of the clypeus 

 with a narrow bidentate tooth, the lobes of which are acute. The 

 space between the eyes at the top about twice as great as the space 

 between them at the clypeus. Front very finely granular ; the vertex 

 with fine close punctures; there is no impressed line from the an- 

 terior ocellus, but the anterior ocellus is in an indistinct pit. Apical 

 antennal joint tapering, slightly curved, as long as the three preced- 

 ing joints combined; third antennal joint about the same length as 

 the fourth, perhaps a little longer. Dorsulum with distinct scattered 

 punctures. Pleurae similarly punctured, the suture straight and deep. 

 Scutellum sculptured like the dorsulum, not impressed. Metanotum 

 rugose to striato-granular, the strue mostly longitudinal, but slightly 

 oblique ; there is no impressed median furrow. Metapleurae shining, 

 finely striated ; posterior face granular, with a deep furrow. Legs 

 without spines. The first abdominal segment but very little longer 

 than the second, and but slightly nodose at the apex. Color, black; 

 palpi, pale ; tegulse and fore tarsi brownish ; spurs pallid. Wing? 

 hyaline, the apical margin dusky, iridescent ; venation black. 



Type locality : Fedor, Texas. Described from one male col- 

 lected by G. Birkmann, May i, 1904. 



This species is closest to frigidmn. Besides the character 

 given in the foregoing table it may be separated from fricjl- 

 dinu by the longer second abdominal segment, and the brownish 

 tegulse.
