29. Cryptohypmis Powelli, n. sp. 



C. subdepi-essus, tenuissime pubescens, niger, antennis fusco-testa- 

 ceis, pedibus testaceis ; antennis tenuibus, sat elongatis, artienlo 

 tertio elongate, secundo longiore quarto fere sequali; prothorace 

 lateribiis rotundatis, basin versus angustato, angulis posterioribuB 

 minutis acutis, crebre subtiliter punctato, medio canaliculato ; 

 elytris distincte striatis, interstitiis nullo modo clevatis, obsolete 

 rugulosis. Long. 7-0 m. m. 



The female.is rather larger than the male, and has the hind 

 angles of the thorax, though acute, not at all prolonged. 

 Craigie-burn : found by Mr. Powell. 



30. Cryptohypnus humilis^ n. sp. 



C. subdepressus, tenuissime pubescens, niger, antennis pedibusque 

 testaceis ; prothorace lateribus rotundatis, ante basin constricto, 

 angulis posterioribus gracilibus peracutis, sat elongatis, fortiter 

 divergentibus, crebre subtiliter punctato, medio canaliculato ; 

 elytris sat profunda striatis. Long. 7-9 m. m. 



Though extremely similar to the preceding species, this 

 may be readily distinguished by the more prolonged hind 

 angles of the thorax. The differences between the sexes seem 

 to be very slight : the female is rather larger, and has the 

 thorax a little more dilated at the sides. 



Wellington, Feb. 1875 ( Wakefield).
