NOTES ON BRITISH GEODEPHAGA. 51 



Geod. Brit. p. 26. Taken plentifully in Preston Marsh, 

 and at Lytham, by Messrs. Graham and Constantine, to 

 both of whom I am indebted for some interesting varieties. 



Dyschirius obscurus, Gyll. Ins. Suec. iv. 456 (Clivina); 

 Dawson, Goed. Brit. p. "297. This species was introduced 

 by me at the last moment before going to press, and I had 

 no opportunity of describing it from actual types ; this defi- 

 ciency I am now able to supply from specimens before me ; 

 therefore erase the paragraph beginning " This species," and 

 substitute the following description. 



Head small, flat, dull black ; antennas black, with the 

 base pitchy red. Thorax dull metallic black, sides globose 

 and rounded, being widest just behind the middle, dorsal line 

 deep and entire. Elytra brassy or bronzed, humeral angles 

 a little distinct, sides moderately rounded ; deeply striated, 

 the strice entirely impunctate, finest near the extremity ; 

 underside black; legs pitchy; anterior tibiae armed externally 

 with two distinct teeth, the one at the extremity largest. 



Length 1| lines. 



It resembles thoracicus in form, but differs in several im- 

 portant respects, more especially in the deeply impressed and 

 entirely impunctate strice of the elytra, and the form of the 

 dentations of the epistoma. 



Chlcenius Schrankii, Dufts., Faun. ii. 131 (Carahus). 

 Head shining green, glabrous, the hinder part sometimes 

 coppery ;' mandibles pitchy red; palpi and three joints at 

 the base of the antennae testaceous red, the upper joints 

 fuscous. Thorax green-coppery, subquadrate, the sides 

 rounded and widest in front below the angles, thence ob- 

 liquely narrowed to the base ; posterior angles nearly right 

 angles, the surface coarsely punctulated, the punctulation in 

 some places confluent, the base with two foveas. Elytra 

 green, clothed with a rich shining rusty pile, striated, the
