COpi.SONIDAE. 251 



As I have already instituted no fewer tlian foi-ty new genera in this 

 group, it is not advisable to create others unless necessary for specially 

 distinct species. 



3655. Agastegnus concinnus sp. nov. Agastegnus Broun, Trans. N.Z. 



Inst., vol. 41, p. 182. 



Subdepressed, niodeiately broad, nitid, variegate; the head, front 

 of thorax, and club piceo-fuscous; antennae, rostrum, legs, and re- 

 mainder of thorax more or less rufescent; elytra testaceous, but reddish 

 at the sides, and with a faintly infuscate spot on the middle of each 

 elytron, and another on the summit of the posterior declivity, both, 

 however, are obsolete; the elytra bear some rather short inconspicuous 

 greyish hairs, but those on the head and thorax are elongate, slender, 

 depressed, and bright yellow. 



Rostrum rather shorter than the thorax, moderately broad and 

 parallel in front, gently narrowed behind the middle, slightly arched; 

 more finely punctured in front than behind, nowhere closely. Head dis- 

 tantly punctate, the occiput nearly smooth. Thorax rather longer than 

 broad, moderately I'ounded and widest bt'liind the middle, more 

 gradually narrowed in front than behind, constricted near the apex, 

 the basal margin thickened at the sides and almost forming distinct 

 angles ; it is moderately coarsely but not closely punctured, but the 

 dark apical space is almost smooth"; there is an oblong basal impres- 

 sion, Avitli a smooth central line proceeding from it as far as the frontal 

 constriction. Scutellum distinct, smooth. Elytra truncate at the base, 

 distinctly broader than the thorax there, twice its length, gradually 

 narrowed near the extremity; they are nearly plane and without dorsal 

 depressions, closely and distinctly striate-punctate, more evidently striate 

 behind; interstices with minute serial punctures, the 3rd somewhat 

 thickened and elevated towards the extremity, sharply bent and angulate 

 there, and extending for a short distance along the side, the space 

 enclosed by the fork thus formed is distinctly depressed. 



Scape inserted before the middle, slightly flexuous, a good deal 

 thickened near the extremity; 2nd joint of funiculus nearly as long as 

 the basal, joints 4 and 5 transverse; club lai-ge, oblong-oval, densely 

 pubescent. 



The North Island A. coloratus, 1630, is the only similar species; 

 this one, however, is a trifle more robust, it is more brightly coloured; 

 its thorax is more gradually narrowed anteriorly, and the discal 

 impression does not extend forwards; the elytra are less abruptly 

 narrowed posteriorly, and their pubescence in 1630 is quite elongate; 

 the legs and rostrum are stouter, but the eyes are less prominent. The 

 penultimate tarsal joints are slightly dilated, excavate above at the 

 extremity, but not bilobed. 



^. Length (rostrum inclusive), 3 mm. ; bi-eadtli, ^ nnn. 



Mount Hutt, near Methven. Described fi-om a solitarv individual 

 found bv Mr. T. Hall, at a height of 3,500 ft., on the 14th February, 

 1912. 



3656. Agastegnus thoracicus sp. nov. 



Subdepressed, elongate, narrowed anteriorly, shining; red, antennae 

 and tarsi a little paler; very scantily clothed witli suberect grey 

 pubescence.
