Hypharpax. 



McLeay ; Lacord. Hist, des Ins. Coleop., Tom. i., p. 233. 



Mentum transversal, moderately emarginated, with a rather strong 

 single tooth, its lateral lobes outwardly rounded, terminating in a rather 

 sharp point. Last joint of the palpi slightly fusiform, truncated at the- 

 end. Mandibles short, arched, and sharp. Labrum transversal, rounded 

 at the angles, slightly hollowed in front. Head moderate, a little nar- 

 rowed behind. Antennce longer than the prothorax, thickening a little 

 towards the extremity ; their first joint longer and thicker than the fol- 

 lowing, which are about equal to one another. Prothorax transversal, 

 rounded laterally, very slightly rounded behind, having two fossae at its 

 base near to the posterior angles. Elytra moderate, parallel, rounded 

 behind, striate. Legs robust, moderate ; hind femora of the males 

 stout, unidentate below; tibia of the same pair arcuated, finely dentate 

 inwardly throughout their whole length ; the four first joints of the four 

 anterior tarsi strongly dilated in that sex, the joints strongly cordiform, 

 rounded at the angles, the second a little larger than the others, which 

 are equal. 



100. H. antarctiCUS, Castelnau; Trans. Roy. Soc. Viet., 1867, p. 

 193. Copper coloured; head smooth, with a transverse line in front, 

 having a punctiform impression at each end ; thorax almost quad- 

 rangular, transverse, rather rounded, and bordered laterally: a feeble 

 impression near each anterior angle, and a strong one behind ; a feeble 

 transverse impression in front, and a longitudinal stria on the middle, 

 very little marked ; elytra rather short, depressed, striated, a feeble 

 punctiform impression behind, between the second and third striae, and 

 a line of impressions on the lateral margin; lower side of the body of 

 an aeneous brown, very brilliant ; legs brown, with the extremity of the 

 tibiae obscure ; palpi and antenna? brown, the basal article rather red. 



Length, 2\ lines. 



Dunedin and North Island. About the form of Harpalus ceneus, 

 but very much smaller. 



NOTE. Count de Castelnau placed this species in the genus Har- 

 palus; Mr. Bates, however, found "that it scarcely belongs to Hypharpax, 

 the hind tibia of the male not being arcuated ; in facies and in the 

 long fine bristles on the inner side of the tibia, with a row of shorter 

 spines on the outer side, it resembles that genus. Four joints of the 

 four anterior tarsi of the male are dilated, and smooth, brush-like 

 beneath." I found this insect at Auckland.

 angustato, lateribus antice late rotundatis, angulis posticis paulo obtusis
