8o6 COLEOPTERA 



sub-bilobeJ, the terminal equalling the other three. Anterior coxcb 

 distant. Body pilose. 



Differs from Pentarthriim and Sericotrogus in having long legs, a 

 short head, and depressed eyes, whilst the form of the antennal club 

 separates it from Macroscy talus, to which it is, on the whole, most 

 nearly allied. 



Besides the typical species it includes Nos. 922 and 930, w-hich 

 must accordingly be named A. gratus and A. longipes. I have a 

 specimen of Dr. Sharp's Sericotrogus siinulans, or what I believe 

 to be one. If I have judged correctly it belongs to this genus, 

 but, as the author does not allude to " long legs and flattened 

 eyes," it must be considered doubtful at present. 



1432. A. ruficollis, ^^-s- Slender, moderately elongate, 

 sub-depressed, clothed with fine elongate yellowish hairs ; beak 

 and thoracic disc rufescent, elytra and legs piceous, the latter 

 darker; antennae testaceous-red, the club and tarsi pitchy-red. 



Rostrum shorter than thorax, not broad, gradually expanded 

 towards the extremity, nude, shining, sparingly and finely punc- 

 tured. Head more coarsely punctated, pubescent. Prothorax 

 longer than broad, sub-depressed, constricted and narrowed in 

 front, obtusely rounded behind the middle, leaving an evident 

 gap between it and the humeral angles, moderately coarsely but 

 not very closely nor rugosely punctured ; the intervals between 

 the punctures very minutely punctulated. Scutellum smooth. 

 Elytra rather broader than thorax, about twice its length, scarcely 

 rounded laterally, sub-depressed ; coarsely striate-punctate ; inter- 

 stices almost imperceptibly and remotely punctulated, the second 

 sensibly elevated near the apices, and curved towards the external 

 ones. Legs long, clothed with fine greyish hairs. 



If the base of the thorax be carefully examined, it will be 

 seen that the punctures are replaced by minute, transverse, linear 

 impressions. The thorax of A. longipes is much broader and 

 more strongly rounded at the sides, and is longitudinally de- 

 pressed on the disc. 



Length, ^ line ; breadth, less than 1. 



My specimen is from the Waitakerei. 



Bseorhopalus. 



Nov. gen. 

 Ptostrur.i moderately elongate, slightly arched, considerably 

 contracted behind, in front sub-parallel ; its scrohes short and 

 profound, not capable of receiving the scape, wliich is ac- 

 commodated along the posterior contraction. Antenna short 

 and stout ; sccyje a good deal incrassated apically, attaining 

 the middle of the eye ; funiculus 5-jointed, second articulation 

 rather longer than third ; club ovate. Head exserted but not 

 elongate, curvedly narrowed in front, with a linear post-ocular 

 impression ; the neck broad. Eyes small, not prominent, per- 

 ceptibly granulated. Prothorax not much longer than broad,
