1116 COLEOPTERA 



1977. C. discoidea, ''■••!>■• Convex, shining, head and thorax 

 fusco-violaceons \\\i\\ 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 iDreast pilose. 



Head moderately and distantly punctured ; the clypeus more 

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

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

 second rather short and stout ; third considerably shorter than 

 fourth ; fifth short ; club elongate, compact, triarticuiate. Thorax 

 transverse, its sides nearly straight behind, obliquely narrow^ed 

 towards the prominent anterior angles, apex deeply emarginate, base 

 medially lobate and sinuated laterally ; its sculpture similar to that 

 of the head. Scutelbim 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. Pyyidiiuii fuscous, remotely punctated. 



Underside infuscate, coxaB and trochanters testaceous ; posterior 

 coxae acutely prolonged backwards. 



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

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

 decidedly shorter. 



Length, 8i ; breadth, 4i lines. 



Mr. Cheeseman picked up a dead male specimen on Mount 

 Arthur at an elevation of about 5,000ft. 



Pyronota. 



1978. P. electa, ^^-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. Tibia 

 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 tibias, and in having longer coxal spines. 

 Apices of elytra almost obliquely truncate.
