above the facial hollow with a transverse carina, the little cariuse 

 branching upwards from the latter irregular; head posteriorly 

 transverse ; antenna short, somewhat thick ; the 2nd joint of the 

 ^nagellum long, more than twice the length of the 1st joint. 

 Thorax massive; the pronotum very convex, transversely rect- 

 angular, the sides widely emarginate anteriorly, a slight depression 

 m the middle ; propleurse with two large depressions ; mesonotum. 

 scutellum and postscutellum forming a regular and somewhat 

 gentle convexity ; the median segment depressed and with a broad 

 V-shaped hollow posteriorly formed of 4 large depressions, the 

 posterior lateral angles broadly produced, subacute; mesopleurse 

 coarsely irregularly cribrate, blunt beneath, the apex margined by a 

 carina, which is continued posteriorly up to the bases of the wings ; 

 the latter brownish hyaline, the nervures brown, the tegulse with 

 the basal half blue, the outer half green ; legs short and robust. 

 Abdomen : the basal segment subemarginate in the middle at base, 

 the 2nd and 3rd segments medially broadly subcarinate ; the ante- 

 apical series of fovea? on the 3rd segment large and well-marked ; 

 the apical margin with 6 large triangular teeth, the medial 4 sub- 

 acute and long, the outer one on each side shorter, broader, more 

 obtuse. 



c? Similar, smaller and slighter.

2 . Exceedingly like 0. principalis, Smith, of which it may be 

 merely a local race. Differs in having the pronotum, the anterior 

 half of the mesouotum and the abdomen much more sparingly 

 punctured than in C. principalis ; the intervals between the large 

 punctures on the mesonotum and pronotum are, in the type speci- 

 men in the British Museum, minutely punctured, and the punc- 

 turing on the abdomen is much more regular and neater than in 

 G. princij tails. Beyond this I can see no difference.

$ . Metallic dark green ; the occiput, the median segment 

 posteriorly and the middle from the base to near the apex of the

 dark blue except for a transverse narrow band of green in front of
