228 Mr. H. W. Bates' supplement to the 



not form such regular rows on the summits of the lines ; 

 the depressed interstices or striae have perceptible punc- 

 tures. A remarkable feature in the thorax of the female 

 is that the flanks are visible, in the middle on both 

 sides, when the insect is viewed from above. As in C. 

 exilis, and to a less degree in the allied forms, there is a 

 submarginal shining streak extending for a short distance 

 from the shoulders of the elytra. 



The four preceding are without doubt no other than so 

 many local forms of one species, but it would be difficult 

 to frame a description to fit the whole, and if they were 

 treated as one there would be no valid reason for not in- 

 cluding C. procerulus and its cognate forms with them. 



Carabus porrecticollis. 



Valde elongatus et angustus, supra fere opacus, niger, 

 capite thoraceque violaceis ; capite postice (cum collo) 

 punctato, oculis valde prominentibus, collo angusto ; 

 thorace valde elongato, lateribus perparum arcuatis, a 

 medio usque ad apicem gradatim et paullo angustato, 

 postice adhuc minus et subrecte angustato ; angulis 

 posticis sat productis (apice obtusis) margine basali 

 recto, dorso sat crebre ruguloso-punctulato ; elytris sicut 

 in C. procerido apice perparum sinuatis ; mas elongato- 

 oblongis, fcem. elongato-ovatis, dorso striis catenatis 

 tribus et inter has lineis tenuissimis elevatis tribus, 

 (interspatio suturali duabus tantum) interstitiis depressis 

 subcancellato-punctatis, lineis et interstitiis granulatis ; 

 ventris segmentis basi arcuatim acute sulcatis. Long. 

 28—30 mm., $ , ? . 



Urasa, and on the north-west coast at Akita and 

 Sakata ; a local species. 



Undoubtedly belonging to the procerulus group, but 

 distinguished by its long thorax, with scarcely rounded 

 or flexuous sides, as well as by its colour and the sculp- 

 ture of the elytra. The tubercles of the chain-striae are 

 sometimes narrow and linear, almost as in C. procerulus, 

 and sometimes much broader. The fine triple elevated 

 lines vary in elevation, the middle one of the three respec- 

 tively sometimes being alone elevated, and all are crested 

 with granulations. The depressed intervals or striae 

 have each a row of large impressions mostly extending 

 quite across the interval.
