DESCRIPTIOXS OF SOME NEW SPECIES, AND INDICATIONS OF NEW 

 GENEEA, OF COLEOPTERA FEOM NEW ZEALAND. 



BY D. SHARP, M.B. 



{Concluded from vol. xiii, page 272.) 



Balcus nioee, n. sp. 



Sat robustus, nitidus, niger, leviter ceneo-micans, obsolete parce 

 punctatus, pilis erectis sparsim vest it us ; antennis articuUs basalibus 

 posterius testaceis. Long. 8 — 10 mm. ; Int. 21 mm. 



Antenna moderately slender and long, 3rd joint slender, longer than the 4th, 

 and much longer than the thick short second joint, 9th joint a good deal broader 

 than the preceding ones, longer than broad, 10th as broad as 9th, but rather shorter, 

 11th sub-oval, acuminate, longer than 9th, longer than broad; their colour is black, 

 but the two or three basal joints are more or less distinctly yellow behind. Head 

 broad and short, its punctuation about the vertex rather closer and more distinct 

 than that of the rest of the upper surface. Thorax as long as broad, much con- 

 stricted in front and behind, so as to be a good deal dilated in the middle, it is very 

 sparingly punctured. Elytra elongate, shining black with a faint metallic tinge, 

 sparingly and finely punctured, and with whitish scanty hairs ; under-surfacc and 

 legs entirely black. 



Christchurcli, found by Mr. "Wakefield. 



I have made another new generic name for this species ; it haa 

 the antennae with a three-jointed very loosely articulated club : the 

 labial palpi with the terminal joint very large ; that of the maxillary 

 also dilated and securiform. Eyes large and prominent, finely 

 granulated, slightly eraargiuate in front. Posterior coxse only slightly 

 separated. Tarsi rather large, apparently only 4-jointed, the basal 

 joint being atrophied above and below, the 2nd, 3rd, and 4th joints 

 with large bilobed membranes, the claws simple. In form, the insect 

 is rather like Thanasimus formicarius, and may be placed near that 

 species, but it has the apical joint of the maxillary palpi large, and the 

 basal joint of the tarsi more atrophied. 



PlITMATOPlIJEA niLAEIS, n. Sp. 



Lcete violacea, niiida, fere impunctata, elytris bulla elevata macu- 

 laque laterali Jlavis ; antennis tarsisque nigricantibus, trocliantcrihus 

 etfemorum basibus Jlavis. Long. 7 mm. ; lat. 2\ mm. 



Antenn£e testaceous, with the basal joint obscurely testaceous behind. Thorax 

 a little longer than broad, the sides distinctly prominent a little behind the middle 

 and thence narrowed to the base, the constricted anterior part elongate. Elytra 

 rather long and narrow, with a double elevation behind the scutellum ; behind 

 these scuteUar elevations, on each is an elevated bright yellow spot, and again just 

 beliind this is a large yellow elevated patch reaching the lateral margin but not (he 

 suture; their surface is almost impunctule.
