having laterally a small raised spot near the somewhat obsolete 

 supra-marginal fossa ; elytra elongate, as broad at base as the pro- 

 thorax, geminato-striate, and with the supra-marginal interval 

 carinate ; epipleura narrow ; mesosternum broad, nearly fused with 

 the metasternum, but having still a trace of the suture ; anterior 

 tibiae dilated, truncate at tip, apical spur set close to the inner angle, 

 bifid at tip in the male except in P. costata, outer part of tibiae dis- 

 tinctly tri-dentate, intermediate and posterior tibise compressed, 

 dilated triangularly at apex, sharply uni-carinate on the upper side 

 and not serrulate ; anterior tarsi slender, intermediate and posterior 

 somewhat short, sub-triangular and decreasing a little in size, basal 

 joint very little wider than the second and third. 



The difference between Pedaria and Saroiohorus, apart from the 

 facies, seems to consist only in the elytra being sinuate laterally 

 near the base in the latter ; this sinuation is, however, variable in the 

 three species which should, on that account, be included in 

 Sarophojnts. 



The valves of the penis are of two very different types (vide 

 pi. xxxviii., figs. 29 and 30), but the last figure is too symmetrical.
