I 39- C. dilutUS, -S- Narrow, oblong, sub-depressed, thickly 

 rod with fine pallid hairs, almost wholl\ HIS. 



Head rather broad proportionally, somew:. ^ fine 



punctation much concealed by the pubescence. Prothorax almo- 

 wide as the elytra at the base, with blunt angles, distantly and 

 minutely punctured. Elytra parallel-sided, rather tlat, but without 

 obvious depressions, finely and distantly punctulated. Antenna 

 robust, rather long, third articulation half as long as fourth. 



Of remarkably elongate outline; cannot well be mistaken; super- 

 ficially resembling a small Mesocyphon, or Atopida testae.

I found one specimen only at Tairua. 



Group-M E L Y R I D ^3. 

 Arthracanthus. 



Nov. gen. 



Allied to Dasytes ; differing principally in the maxillary palpus 

 terminating in a broad joint obliquely truncated at the extremity, 

 and therefore sub - securiform ; and in the structure of the tarsi, 

 the anterior having the basal joint shorter than the second, with a 

 yellow spiniform protuberance close to its external apex. The claws 

 are not perceptibly appendiculate, though thickened at the base ; 

 large and prominent. 



1391. A. planifrons, n.s. Sub-depressed, moderately elon- 

 gate ; bluish, head and thorax darkest, elytra slightly infuscate, legs 

 and four first antennal joints castaneous; moderately glossy, clothed 

 with fine cinereous hairs. 



Head rather broad, plane in front, distinctly and finely punc- 

 tured, but densely and minutely sculptured on the occiput and near 

 the eyes. Antenna longer than head and thorax, not serrate, fourth 

 joint just appreciably shorter than third or fifth, ninth and tenth 

 distinctly expanded apically, sub-triangular, the terminal quite as 

 long as its predecessor. Prothwax a little longer than broad, not so 

 wide as the head, medially dilated laterally ; transversely impressed 

 near the base and apex, the sides and front most punctated, the 

 basal sculpture similar to that of the occiput. Scutellum small, 

 transversely quadrate. Elytra broader than thorax, rugosely punc- 

 tured. Legs elongate, the basal articulation of the posterior tarsi 

 longer than fifth.

I captured ray specimen on the Waitakerei Hills (Auckland). 



Dasytes (p. 328). 



1392. D. constrictus, n-s. Narrow, elongate, sub-depressed, 

 clothed with short, obscure, yellow hairs, most sparingly and finely 

 on the head and thorax ; dark-blue, shining ; legs and antennas 

 variegated rufo-piceous. 



Head moderate, indistinctly tri-sulcate (two grooves interocular, 

 the third medial behind the eyes), rather finely punctured, least so
