OF NEW ZEALAND. 289 



and rounded anteriorly, the hind angles are acute and directed almost 

 posteriorly; its surface is finely punctured and clothed with pallid hairs. 

 The elytra are rather elongate, and considerably attenuated behind ; 

 each bears four, more or less distinct, discoidal stride, the external space 

 is irregularly sculptured, and there is an obvious humeral costa ; they 

 are clothed with pallid hairs. 



Length, t line ; antennae, f line. 



Described from a single specimen which I found at Parua, Whan- 

 garei Harbour.

T\\t forehead \% much curved in front so as to be somewhat produced 

 in the middle, it is sharply defined by a scarcely elevated line which 

 overhangs the clypeus, so that there is an abrupt step between the front 

 and the labrum ; the antenna! spaces are very obscure ; the antenna are 

 slender, with second and third joints only moderately developed. The 

 prosternal sutures are not distinctly duplicate, and are not open in front, 

 but show there a peculiar sinuation. The prosternal process is short, and 

 is abruptly and greatly bent upwards immediately behind the coxae. 

 The middle coxce are only narrowly separated ; the niesosternal cavity 

 shows no distinct lateral edge, and is quite depressed \ its opening 

 behind is narrow and ill-defined, and does not reach the intercoxal 

 suture ; the posterior portion however is prolonged backwards as a 

 broad shallow depression on the hind part of the mesosternal process. 

 The femoral portion of the coxal plate is excessively short — in fact, 

 linear ; the trochanteral portion is moderately large. The tarsi are 

 moderately short, and all the joints are simple ; the fourth is small but 

 not minute. 



The only exponent of the genus presents a combination of structural 

 characters such as require its isolation from the other New Zealand 

 allies. I think the genus should be placed near Betar/non, from which 

 it differs strikingly by the prosternal process and mesosternal cavity. 



508. A. modestus, 6"//^//; Ann. Mag. N'at. Hist., May, 1877. 

 A. angustulus, sat nitidus, evidenter pubescens. fulvo-castaneus, pedibus 

 testaceis ; antennis elongatis, tenuibus, articulis secundo et tertio con- 

 junctim (]uarto fere jequali ; prothorace brevi, parcius punctato, angulis 

 posterioribus baud divergentibus, subuncatis ; elytris regulariter striatis, 

 stnis evidenter punctatis, interstitiis obsolete punctatis. 



Long., 6-7 mm. 



The male is more slender than the female. The species has much 

 the appearance of our Euroi)ean Adrasti and Dolopii. 



I have seen but few specimens of this species; they have been sent 

 me by Ca[)tain Broun from Tairua, with the information that it is an 

 autumnal species and inactive.
