NOTES, ETC. 95 



This species is very abundant in most localities; I have 

 repeatedly bred it from bramble sticks, which contained nests 

 of fossorial H}/menoptera, or those of Prosopis, but I have 

 not ascertained upon which it is parasitic ; I have frequently 

 noticed it in company with C, bidentataj entering the burrows 

 of Odynei'us spinipes. 



10. Chrysis ORNATA, Smith, Zool. Append. ix. cxxv. (1851.) 

 Male. Lenojth 4| lines. Head golden-green, with the 

 vertex dark blue ; the thorax, legs and apical segment of the 

 abdomen golden-green ; the thorax with a mixture of golden 

 and coppery effulgence above, dashed with a faint tinge of 

 carmine in parts; the scape green, the flagellum and tarsi 

 black ; the wings slightly coloured ; the two basal segments 

 of the abdomen of a rich carmine-red, very minutely and 

 closely punctured, the extreme base more strongly so ; the 

 base of the apical segment blue, with the apex edentate, 

 evenly rounded, not laterally angulated. 



This very beautiful insect was taken by Mr. Hewitson, who 

 presented it to me ; it closely resembles C. bidentata, and 

 possibly it may be an extreme variety, but the structural 

 differences are so great that I have kept it separate in the hope 

 that its locality, Bristol, may be assiduously searched, when 

 more examples may be found. It differs from C. bidentata 

 in being larger than any of that insect that I have seen ; its 

 prothorax is much more prolonged ; the abdomen is as finely 

 punctured as in C. neglectaj and the apex of the terminal 

 segment of the abdomen is rounded and without teeth ; the 

 second discoidal cell is also considerably longer and larger. 



Genus III. Euchr^us, Latr. 

 Head large, transverse, as wide as the prothorax ; antennae 

 13-jointed in the male ; the clypeus large, slightly elevated,
