 T}^e, Stethopachys formosa, Baly. 



Stetliopacliys represents, in Australia and the adjacent islands, 

 Plectonychis, Lac, differing from that genus in possessing elongate 

 claws, and in the different form of the mesosternum ; this jjart, 

 instead of being concealed by the projecting metasternum (as in 

 Plectonychis), is in the present case elongate, and placed perpen- 

 dicularly against the produced anterior stirface of the latter, its 

 truncate apex curving sHghtly forwards, and terminating on a level, 

 or nearly so, with the lower surface of the metasternum. 



Stethopachys formosa. 



S. subelongata, subcylindrica, nitidissimo-fulva ; antennis, oculis, macula 

 verticali, scutello, plaga magna metapleurali utrinque, tibiis tarsisque 

 nigris; thorace subconico, basi unifoveolato, lateribus medio valde 

 constrictis; elytris punctato-striatis, pmictis basi profunde impressis, 

 striis ad apicem fere dilatatis, utrisque fasciis duabus latis, prima baseos, 

 macula basali trigonata fulva includente, altera pone medium nigris. — 

 Long. 4 lin. 



Hah. Australia. 



Ijower portion of the face moderately produced ; antennae nearly two- 

 thirds the length of tbe body, filiform, four basal joints nitidous, the 

 others opake, second and third joints short, submoniliform, fourth 

 rather longer than the third ; thorax slightly transverse in front, rather 

 broader at the base, sides deeply constricted in the middle, base above 

 impressed with a small deep fovea, middle of the disk impressed by 

 several irregular rows of fine but distinct pimctures, which form to- 

 gether a broad longitudinal vitta; scutellum truncate; elytra much 

 broader than the thorax, slightly narrowed towards their apex, each 

 elytron impressed with ten rows of distinct punctures, their interstices 

 plane, tenth row sulcate, the punctures on the basal half of the four or 

 five inner rows large and deeply impi'essed, the puncturing of all the 

 strife very fine towards their apex ; hinder thighs shorter than the 

 abdomen ; claws large, gradually increasing in length from the first pair 

 backwards.
