168 THE CANADIAN ENTOMOLOGIST. 



We omit purposely all references to Mr. Scudder's notices of these species. 

 Two brief notices of the occurrence of T.falacer in New England preceded 

 the paper in the Boston proceedings noticed, and to which the present is a 

 reply. 



With respect to the geographical distribution of the two species, while 

 occurring side by side in the Atlantic District, it is probable that Thecla 

 inorata, already found from Canada to Georgia, may be found over a wider 

 expanse of territory than Thecla falacer.

67. Trechus [Bradycellus] tibialis, Kirhy. — Length of body 2f 

 lines. Only a single specimen taken. 



[47] Body black, somewhat glossy. The tip of the palpi and scape of the 

 antenna? are rufous ; the prothorax is rather wider than long, but nearly 

 square; the short basilar furrows observable in Argutor distinguish this 

 species from the succeeding ones : elytra lightly furrowed, furrows impunc- 

 tured : in the usual situation adjacent to the second furrow a little beyond 

 the middle of the elytrum a very minute punctiform impression is just 

 discernible ; the lateral margin and suture at the apex of the elytra are 

 reddish : the tibiae are rufous but the cubit is blacJi at the tip ; the tarsi 

 are darker, the hand has four dilated joints as in the other species of the 

 genus.
