254 LAMELLICORNIA. 



short, highly polished, elevated dorsal line or space near the base between the basal 

 ends of the two broad oblique discal sulci, which never fails in the large series 

 examined, also distinguishes the species. Blanchard's phrase " prothorace .... 

 ruguloso .... lineola laevi notato," and the numerous examples labelled S. mexicana, 

 Blanch., in the Salle collection show that this is the species Blanchard had in view, and 

 not S. protect.

The thorax is almost evenly convex, without foveae or very distinct impressions, and 

 is wholly alutaceous, opaque, and pubescent. In comparing the large series of this and 

 the two preceding species the present appears to be generally of larger size and more 

 diverse in the colours of the elytra, the state of the typical S. marginata being exceedingly 

 uncommon. Rare examples occur which are partly intermediate, not only between this 

 and S. mexicana but also between S. intermedia and S. marginata, and prove that 

 they are all forms of one stock, barely segregated into species.

Distinguished by the dense and strong subrugose punctuation of the thorax ; the latter 

 is without foveae or depressions, narrow, and subangularly dilated in the middle, with 

 porrect acute front and hind angles in the male, broader and less acutely angular in the 

 female, its colour being variable — sometimes wholly dark greenish metallic, but more 

 often tawny-red, like the elytra, with or without a green patch on its anterior part, the 

 curiously declivous lateral margins being sometimes yellow, but not the basal margin. 

 The under surface and pygidium and the apical margin of the propygidium are densely 

 clothed with long recumbent tawny-ashy hairs. The mesosternum is subvertical, slightly 

 tumid at the apex. The lateral margin of the elytra, in the female only, has an abruptly 

 formed, much thickened and vertically arcuated, wheal. 



In Guatemala examples occur with the elytra lineated with fuscous.
