1116 COLEOPTERA 



1977. C. discoidea, n.s. Convex, shining, head and thorax 

 fusco-violaceous with a greenish tinge, the sides of the latter, and the 

 legs, testaceous ; clypeus and elytra testaceous, but with a greenish 

 hue ; scutellum green ; antennae fuscous, club blackish ; the sides 

 and base of thorax and the elytral margins sparsely fringed with 

 long pallid hairs, pygidium and breast pilose. 



Head moderately and distantly punctured ; the clypeus more 

 coarsely, its apex emarginate. Eyes not prominent. Antenna of 

 moderate length ; basal joint hairy, elongate, incrassated apically ; 

 second rather short and stout ; third considerably shorter than 

 fourth ; fifth short ; club elongate, compact, tri articulate. Thorax 

 transverse, its sides nearly straight behind, obliquely narrowed 

 towards the prominent anterior angles, apex deeply emarginate, base 

 medially lobate and sinuated laterally ; its sculpture similar to that 

 of the head. Scutellum curvilinearly triangular, punctate. Elytra 

 distinctly striate-punctate, the alternate interstices more elevated 

 than the others, none of them perceptibly punctured; apices rounded, 

 not spiniform at the suture. Pygidium fuscous, remotely punctated. 



Underside infuscate, coxae and trochanters testaceous ; posterior 

 coxae acutely prolonged backwards. 



The insect resembles in form the well-known Stethaspis suturalis, 

 the legs also are similar, but the four basal joints of the tarsi are 

 decidedly shorter. 



Length, 8-J-; breadth, 4J lines. 



Mr. Cheeseman picked up a dead male specimen on Mount 

 Arthur at an elevation of about 5,000ft. 



Pyronota. 



1978. P. electa, n.s. Oval, shining, of a beautiful pale-red, 

 tinged with blue behind ; thoracic vitta and elytral suture almost 

 scarlet, a greenish-yellow stripe on each side of the latter ; legs 

 infuscate-red ; underside obscure-red. 



Thorax more narrowed before the middle than behind. Tibice 

 stout, tridentate externally. Elytra rounded apically, not at all 

 truncate. 



$ . Length, 4| ; breadth, 2 lines. 



Parua, Whangarei Harbour. One female. 



1979. P. regalis, n.s. Shining, crimson-red, thoracic stripe 

 paler and rather indistinct, suture of elytra golden-green ; tibiae 

 fusco- testaceous ; underside castaneous. 



Thorax gradually narrowed towards the front. Tibia (anterior) 

 with one broad angulation in addition to the terminal projection. 



This differs from P. electa in the form of the thorax, in the 

 structure of the front tibiae, and in having longer coxal spines. 

 Apices of elytra almost obliquely truncate.
