 (slightly interrupted in middle), scutellum (except irregular 

 anterior edge), and postscutellum. Process of labrum brown, 

 extremely broadly truncate ; clypeus sparsely punctured ; 

 facial quadrangle broader than long ; eyes pea-green ;

 rather long and narrow, shining black, with broad ferru- 

 gitious bands at bases of second and third segments, ex-

? . — Length about 6 mm. 



Black, with cream-coloured markings. Very close to 

 C. permacidata (Ckll.), but much laiger, wings strongly 

 dusky in marginal cell and apical field ; instead of spots 

 above eyes are long transverse stripes (each longer than the 

 interval between them), mesothorax anteriorly with two 

 transverse spots, tegulse with small light spots, tiansverse 

 dorsal marks on third and fourth abdominal segments only 

 narrowly separated, and none of them as widely sejjarated as 

 half the length of one. Also very close to C. nyssonoides 

 (Brues), but second r. n. joining second s.m. nearer end, 

 wings dusky, vertex and mesothorax punctured about alike 

 bands instead of spots on head above, lateral spots on first 

 abdominal segment not larger than the middle ones, and 

 other small details.
