1284 COLEOPTEEA 



tured, depressed near base and apex, each side with three obtuse 

 inequalities. Elytra one-third narrower behind than at base, 

 moderately punctured, fewer punctures behind, apices a little pro- 

 duced at the suture, truncate. 



Clothing and legs similar to G. urbanus ; it is not the female of 

 that species, however, nor do I think it can be G. nigricollis. The 

 apical ventral segment is similarly formed. 



$ . Length, 4-J- lines ; breadth, 1 line. 



Mount Arthur. One female, found by T. R Cheeseman and 

 J. Adams. 



2260. G. picticornis, n.s. Body elongate, shining, sparsely 

 clothed with erect, slender hairs ; head, thorax, posterior portion of 

 wing-cases, and sternum dark-violaceous; basal portion of elytra 

 testaceous ; legs fulvous, femora more rufescent ; two basal articu- 

 lations of antennae dark-blue, punctate, and shining, joints 3-7 

 quite opaque, black, eighth and ninth paler, tenth and eleventh pale- 

 yellow. Abdomen fulvous. 



Male. Antenna longer than body, scape shorter than third or 

 fourth joints. Thorax longer than broad, angularly dilated laterally 

 and bearing four obtuse, but not prominent, discoidal elevations. 

 Elytra distinctly punctured but not so deeply behind, their apices 

 almost semicircularly excised. 



Female. Antenna three-fourths the length of the body, not 

 so stout as those of the other sex but similarly coloured. Thorax 

 rhomboidal. 



I have pointed out the characters which seem to differentiate 

 the pair I have seen from the typical form, and, although I have 

 applied the name G. picticornis, I feel doubtful as to whether the 

 insect will prove to be a valid species. I possess one female which 

 agrees with Bates's description ; in it the antennas are quite black 

 and dull. 



Length, 4f lines ; breadth, 1 line. 



Mr. G. V. Hudson was kind enough to present me with the 

 male, which was found at Wakapuaka, Nelson; the female was 

 caught at Karori, Wellington. 



Navomorpha (Gen., p. 589). 



2261. N. Sticticum, n.s. Shining, more or less violaceous, 

 sides of elytra towards the extremity ferruginous, tibiae red, the 

 clothing whitish. 



Head, thorax, and antennae of normal form. Elytra broader 

 than thorax, shoulders not prominent, sides almost parallel to 

 beyond the hind thighs, from thence gradually but not greatly nar- 

 rowed, apices individually rounded ; each elytron with a broad 

 sutural channel beginning 'in line with the middle thighs and attain- 

 ing the apex, filled with whitish hairs so disposed as to cause a 

 spotted appearance behind ; beyond there are two broad, depressed, 

 longitudinal areas indistinctly separated lengthwise by a smooth
