 posticorum articulo basali quam ceteri conjuncti manifeste

 The only very large Ghalcopterus known to me having in com- 

 bination, eyes not bordered by a sulcus, prothoi-ax evidently 

 narrower at the middle than at the base, and tarsi with fulvous 

 cilia. The evident convexity of the interstices makes the elytra 

 appear substriate, somewhat as C. longipenm's, Hope.
