Olochrysis semicuprea n. s. — Head and thorax metallic green, abdo- 

 men cupreous. 



% Length 7 mm. — Clypeus with a black shining margin slightly rounded out 

 disc of the clypeus sparsely distinctly punctured. Face, front, occiput and 

 cheeks with an almost uniform granular sculpture. Space between posterior 

 pair of ocelli a little greater than that between them and anterior ocellus, also 

 distinctly less than space between them and nearest eye margin. First joint of 

 flagellum as long or slightly longer than two following joints united. Length of 

 prothorax distinctly less than the length of the head, slightly impressed in a 

 longitudinal direction medially, the sculpture coarser than that on head, rneso- 

 thorax with visible parapsidal grooves, extending the whole length of dorsulum, 

 sculpture similar to that of head. Tegula? closely punctured. Scutellum and 

 raetanotum more coarsely pitted than pronotum, the lateral spines of metathorax 

 flattened, blunt. First segment of abdomen granular, with sparse, well defined 

 punctures. Second segment finely granular, with a faint longitudinal elevation. 

 Third abdominal segment more finely granular than the preceding, broad, its 

 apical margin semicircular, sixteen punctures in a furrow close to the margin.
