OF NEW ZEALAND. 295 



Cryptohypniis. 



Sharp ; Ann. Mag. Naf. Hist., May, 1877. 



Forehead curved in front, the clypeus in the middle nearly or entirely 

 wanting, so that, though the forehead presents a sharply defined edge in 

 front, the labrum is placed immediately beneath it ; antennal spaces 

 distinct, but much concealed by the horizontal edge of the forehead, 

 and widely distant from one another in the middle ; antennce filiform. 

 Prostcrual process rather long and straight. Afesosternal cavity rather 

 broad, formed by broad but not in the least raised edges, reaching back 

 to the intercoxal suture. Trochanteral portion of coxal plate well 

 developed, but the femoral portion nearly completely absent. Tarsi 

 moderately long, with all the five joints well developed and simple. 



The above structural characters will enable the New Zealand species 

 to be identified. 



522. C. powelli, Siiarp; Ann. Mag. Nat. Hist., May, 1877. 

 C. sub-depress us, tenuissime pubescens, niger, antennis fusco-testaceis ; 

 pedibustestaceis; antennis i&nmhu?,, sat elongatis, articulo tertio elongato, 

 secundo longiore quarto fere sequali ; prothorace lateribus rotundatis, basin 

 versus angustato, angulis posterioribus minutis acutis, crebre subtiliter 

 punctato, medio canaliculato ; elytris distincte striatis, interstitiis nuUo 

 modo elevatis, obsolete rugulosis. 



Long., 7-9 mm. 



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

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

 Craigieburn : found by Mr. Powell. 



523. C. humilis, Sharp; Ann. Mag. A^at. Hist., May, 1877. 

 C. sub-depressus, tenuissime pubescens, niger, antennis pedibusque testa- 

 ceis ; protiwrace lateribus rotundatis, ante basin constricto, angulis 

 posterioribus gracilibus peracutis. sat elongatis, fortiter divergentibus, 

 crebre subtiliter punctato, medio canaliculato ; clyiris sat profunda 

 striatis. 



Long., 7-9 mm. 



Though extremely similar to the preceding species, this may be 

 readily distinguished by tlie 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, February, 1875 (Wakefield). 



524. C. frontalis, Sharp: Ann. Mag Nat. Hist., May, 1877. 

 C. sub-depressus, tenuiter pubescens, niger, nitidus, antennis fuscis, 

 pedibus testaceis, femoribus obscurioribus ; fronte antice in medio 

 abrupte depressa ; thorace elongato, ante basin leviter constricto, angulis 

 posterioribus sat elongatis, crassioribus, vix divergentibus, subtiliter sat 

 crebre punctato medio indiscrete canaliculato ; elytris subtiliter striatis, 

 striis punctatis, interstitiis parce subtiliter punctatis. 



Long., 5i mm.
