ISCHIOPSOPHA EMARGINATA. 187 



by its different coloration , but also by its more slender 

 and parallel form (although being very wide in its shoul- 

 ders) , by the Avant of spines at the apex of the suture , 

 by the different shape of the transverse keel of the pygi- 

 dium , etc. 



Length 21 mm., breadth at the shoulders 11 mm. — 

 Shining green with a bronzy hue ; the tips of the clypeus 

 black , passing into dark purple ; the anterior and inter- 

 mediate femora -with shades of dark purple at the base 

 and apex ; the tibiae bronzy green at the base , passing 

 through dark purple into black towards the apex ; the tarsi 

 black. The palpi and antennae dark pitchy , approaching 

 black , except the club which is dark brown. 



The clypeus strongly punctured , an impunctate space 

 at the vertex of the head ; the lateral margins of the 

 clypeus very slightly raised. The prothorax less trans- 

 verse than in I. nvjidloha , its lateral margins regularly 

 curved , the median lobe deeply emarginate , the disc most 

 distantly and finely punctured , thickly and somewhat con- 

 fluent along the lateral margins. The slightly rounded 

 apex of the scutellum visible. The elytra at the base 

 broader than the base of the prothorax , deeply sinuated 

 behind the shoulders , then almost parallel ; the apex very 

 slightly notched , and not spined at the suture. The elytra 

 sparingly sprinkled over with very fine punctures, the 

 lateral margin from a little behind the middle covered 

 with deep transverse striae joining the sutural margin 

 across the apical tubercle, the apical portion smooth. The 

 pygidium closely and transversely striated ; the lower part 

 more regularly so than the upper part , the former with a 

 large central impression; the sharp transverse keel straight 

 behind, but broadly rounded laterally. 



Under surface and legs as in /. nigriloha. 



A single female from New Guinea (C. B. H. von Rosenberg).
