new species of llhiendffi. 275 



Trypeticus Grounellei, Mars., 1883. 



This species belongs to a section of the genus in which tlie 

 male lias an asymmetrical rostrum ; the terminal protuberance 

 is largest on the left side. I iiave three other species which 

 are similar in this respect, and 1 think 2\ silvicola, Sch., also 

 belongs to this division, but the description is drawn up from 

 the female, and I am therefore uncertain. 



Teretnosoma festivum, Lew. Ent. M. M. xvi. p. 61 (1879). 



Subcylindricum, viridi-cyaneum, metallicum, undiquc dense pimc- 

 tatum ; anteniaarum clava rufa ; frontc siibdepressa, in medio 

 la;vi ; cljtris taberculo subhumerali Iebvi ; mesosterno antice 

 immarginato ; pygidio in medio transversim carinato ; pedibus 

 rufo-brunneis, tibiis auticis 6-dentatis. 



L. 3-3| mill. 



The mesosternum is somewhat obscurely marginate at the 

 sides, but not round the acumination, and the pygidium has 

 the higher and lower parts divided by a very well-marked 

 carina. This species is more quadrate in form than T. facetum^ 

 Lew., and in its general outline agrees with T. immarginatum^ 

 Lew. 



1 have two specimens of the above species from Jatahy, in 

 the Province of Goyaz, which measure only 3 mill., but 1 can- 

 not see any other difference. The type specimen came from 

 Parana. 



Teretriosoma prasinum^ sp. n. 



Cylindricum, cyaneo-viride, nitidum ; capite basi triangularitor laevi ; 

 pronoto iitrinque tenuiter foveolato ; elytris basi trajisversim 

 impressis ; propygidio pygidioque dense et pariter punctatis ; 

 mesosterno utrinque marginato ; pedibus rulis. 



Cylindrical, bluish green, shining ; the head and epistoma 

 evenly and densely punctured, except a small triangular space 

 in the middle at the base; the thorax, marginal stria com- 

 plete, punctured less regularly than the head, some of the 

 punctures near the scutellum and along the base are the 

 largest, there is a shallow fovea on eitiier side well within the 

 lateral border and midway between the basal and anterior 

 edges, and there is a narrow smooth space before the scutellum; 

 the elytra are transversely impressed at their bases and their 

 punctuation is more even and rather more dense, especially 

 at their apices, than that of the thorax, there is a humeral 

 smooth bodS ; the proi)ygidium and pygidium are very evenly
