angles ; basilar impressions shallow, round and punctured : the elytra exhibit 

 a silliy lustre from the granulations on the surface ; there is a single puncti- 

 form impression in the usual situation near the apex ; in this ?nd the following 

 species these organs arc transversely truncated with a slight sinuosity j legs 

 rufous or rufo-piceous, with black thighs; coxa) and trochanters rufous. 

 [A variety, according to Le('onte, of //. amjnUatus, Say (Ent. Works, ii. 546),

[44] 65. IIarpalus Stepdensii, KirLi/. — A. single specimen, taken in 

 lat 54°. [A synonym of //. ampulatus, *5fiv.] 



[45] 66 SxENOLOPHUs VERSICOLOR, Kirltj. — Length of body 2i to 23 

 lines. Three specimens were taken in lat. 54°, 



Body dusky-black, glossy Palpi, mouth and scape of the antennsc rufous j 

 prothorax scarcely longer than wide, rounded behind, with the basilar impres- 

 sions punctured : elytra reddish-brown, — viewed In the sun or in the light,

 [Previously described as S. fuligiiiosus by Dejean ; is taken in Ontario.] 



67. Trechus [Bradycellus] tibialis, A7/6y.— Length of body 2f 

 lines. Only a single specimen taken. 



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

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

 square; the short basilar furrows observable in AtQutor 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 ioipression is just 

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

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

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

 genus.
