NEW BRITISH SFECIES NOTICED IN 1859. 99 



verso, angulis posticis rotundatis, elytris breviter- 

 ovatis subtiliter punctato-striatis, interstitiis plants, 

 punctis tribus iuipressis, antennis palpis pedibusque 

 nigris. — Long. 3| — 4 tin. 

 A. blach, obscurely greenish brass above, prothorax 

 transverse, posterior angles rounded, elytra short- 

 ovate, faintly punctate-striate, interstices flat, with 

 three impressed points, antenna, palpi and legs black. 

 — Length 3| to 4 lines. 

 Nearly related to A. viduus, but readily distinguished by 

 its usually smaller size, wider prothorax, and the flat inter- 

 stices between the striae of the elytra ; in other respects simi- 

 lar to it. 



Taken by Dr. Power, on Wimbledon Common, in July,

 at the beginning of May last, is entirely black, and presents 

 the raised shoulders and depression in the region of the scu- 

 tellum often observable in marsh-frequenting Carabidce. 



I sent one of two specimens kindly given me by Mr. Rye, 

 and which had been previously submitted to the Rev. J. F. 

 Dawson, and named by him " A. viduus var. versutus, 

 Gyll.," to Dr. Schaum, who writes me that it is " A. ver- 

 sutus, Sturm." 



Dr. Schaum, /. c, gives, without any expression of doubt, 

 Carabus lugubris, Dufts. Faun. Austr. ii. 137, 176 (1812), 

 as a synonym of this species, adding in a note, " I found, in 

 Megerle's Collection, as Car. lugubris, Dufts., a black 

 example of the present species, without brassy tint, and 

 Duftschmidt's remark that the shallow striae distinguish C. 

 lugubris from C. viduus, and that the tibiae and tarsi are
