24' [June. 18SS. 



thorax witli a single lateral seta on the side at the middle, and a minute 

 one at the hind angle, none in front ; base truncate, reposing on the 

 base of the elytra, which possesses a well-marked margin. 



This genus of small Carahidce is allied to Cifclotlwrax, from which 

 it differs by the convex form, the remarkably abbreviate metasternum, 

 and by the structure of the male tarsi ; the condition of these feet I 

 am not, however, able to ascertain very thoroughly. 



Taeastethus pttncticollis, n. sp. 



Nigro-piceus, nitidus, aniennls palpis pedihusque testnceis ; pro- 

 thorace lateribus sinunfis, hasi truncato, utrinqiie imprcsso, et crehre 

 punctato, angulis posferio7'ibus fere rectis ; elytris profunde striatis, 

 striis fortiter ptmctatis, inferstitiis parnm convexis Icemgatis : ahdomine 

 utrinque fortiter punctafo. JLoiuj. 5 mm. 



Thorax narrower than (lie elytra, about as long as broad, with an elongate 

 channel along the middle, with an impression at the base on each side nearly equi- 

 distant from the middle and the outer margin, the whole of the base punctate, the 

 disc nearly impunctate. Elytra short and broad, convex, the shoulders much curved, 

 the eighth interstice elevated at the extremity so as to form a plica. 



I received a specimen found at Greymouth formerly from Herr 

 Reitter, and have now received the insect from Mr. Helms. I have 

 not, however, seen the male. 



TaRASTETHUS LiEVIYElS'TRIS, 11. sp. 



Nig7'o-piceus, nitidus, anfennis palpis pedihusque tesfaceis ; pro- 



thorace laterihus sinuatis, basi truncato, utrinque bi-impresso, fere 



Icevigato ; elytris interne striatis, striis remote px(,nctatis ; abdomine 



Icevigato. Long. 5 mvt. 



This species differs from T. puncticollis in numerous respects ; the thorax is 

 less sinuate at the sides, and is almost without punctuation, there being only about 

 four or five punctures on each side about the middle of the base ; the basal impres- 

 sion is differently formed, so that, viewed in a certain manner, there appears to be a 

 second impression near the outer margin ; the outer striae of the elytra are quite 

 obsolete, but the eighth interstice forms an elevated plica at the extremity. 



It is from this insect that my description of the male tarsus in 

 the generic description is taken ; one of the front legs, however, being 

 gone, I am not very sure about the details : there is no seta in this 

 species at the hind angle of the thorax. Also sent by Mr. Helms 

 from Greymouth.
