f Tin- fnmtal rid-ics eiuiiiif: in the inner niar;iinal tiilx'nles ; 

 insects alwa^'s unicoiorous abr)ve 

 The frontal ridpes extending parallel to the anterior margin 

 6<( of the head to a point between the inner and rmter niar<{inal 

 tubercles, where they end somewhat abruptly ; tin- anterior 

 parts of the elytra conirnonly reddish brown in otherwise 

 blaek insects . . 

 ! Larj^e insects (over 28 nini. Ion;;) ; the puncturing of the 

 ] pronotuni and metasternuni very scanty 



J Smaller insects (not more than 25 mm. lon<;) ; the puncturing 

 [ t)f the ])ronotum aTid metasternum much denser 

 The parietal ridf»es united with the supraorbital ridges ; the 



central area of the metasternuni unpunctured 

 The parietal ridges ending more or less abruptly about half 

 way to the supraorbital ridges ; or. the central area of the 

 metasternum punctured . . 

 The central area of the metasternuni almost invariably with 

 at least a few more or less irregularly placed puncture.s ; the 

 parietal ridges variable 

 The central area of the metasternum with at most one pair of 

 symmetrically placed punctures ; the parietal ridges always 

 ending more or less abruptly about half way to the 

 supra -orbital ridges 

 The pronotuni strongly rectangnlai' ; its anterior angles more or 



less extensively punctured 

 The pronotuni more rounded ; its anterior angles unpunctured, 

 except in small specimens, where a small group may be 

 present 

 The grooves of the elytra not tuberculate 



A more or less distinct polished tubercle formed out of each 

 of the transverse ridges in the lateral grooves of the elytra . . 

 The pronotuni convex, punctured only in the scars and 

 marginal grooves and usually in the anterior angles ; the 

 elytra short, dilated behind : the metasternuni hairy 

 laterally and in front, its lateral and intermediate areas 

 often united 



The pronotuni somewhat flattened, denselv punctured laterallv, 

 its sides practically straight ; the elytra slender, more or le.ss 

 parallel sided ; the metasternum hairless, the intermediate 

 and lateral areas always distinct .. .. .. L. humcros>i.i. p. \]8.
