Species of New- Zealand Coleoptera. 147 



Acalles ^erpusillus . 



A. ovatus, fusco-piceus,"esquamosus, rostro antennisque pallidioribus, 

 illo lineatim punctulato ; prothorace latitudine longitudini sequali, 

 antice constricto, supra vage punctato ; elytris breviter ovatis, 

 prothorace latioribus, biimeris obsoletis, supra modice convexis, 

 fortiter seriatim punctatis, interstitiis latis, Isevigatis; corpora 

 infra vage punctato ; abdomine segmentis duobus basalibus valde 

 ampliatis, tribus ultimis pallidis ; pedi'^^is validis. Long. 1 lin. 



Hah. Tairua. 



A very small pitchy-brown species. 



ACALLOPAIS. 



Rostrum validum, apicem versus gradatim incrassatnm ; aerobes late- 

 rales. Antennce pone medium rostri insertae ; scapus brevis ; 

 funiculus ad clavam gradatim crassior. OcuU majusculi, grosse 

 granulati. Prothorax basi latior, Scutellum nullum. Elytra 

 breviter subcordata. Rima pectoralis ampla, apice cavernosa. 

 Femora crassa, infra canaliculata ; tibke rectse, apice uncinatse ; 

 tarsi articulo penultimo bilobo ; ungues divergentes. 



The pectoral canal is large, terminated by the raised border 

 of the mesosternum, forming a well-marked cavity, to which, 

 as I have explained, I apply the term " cavernosa," whether 

 the raised portion is erect or bent over the apex of the canal, 

 the passage between the two being too gradual to be of any 

 practical value. It is in that character that it differs princi- 

 pally from Acalles. 



Acallopais rudis. 



A. ellipticus, valde convexus, fuscus, squamosus, squamis erectis 

 numerosis adspersus ; rostro nitide fusco, capite vix longiore ; 

 antennis piceis ; prothorace oblongo, utrinque subrotundato ; ely- 

 tris prothorace paulo latioribus, nigro-variegatis, in medio niveo- 

 subquadrinotatis ; abdomine segmentis duobus basalibus am- 

 pHssimis. Long. 1^ lin. 



Hah. Tairua. 



Macratria exilis. 



M. angusta, fusca, albido-setulosa ; capite depresso ; collo testaceo ; 

 oculis magnis ; antennis testaceis, extus infuscatis ; prothorace 

 oblongo, apice angustissimo ; scutello inviso ; elytris seriatim 

 punctatis et setulosis, apice late rotundatis ; pedibus testaceis, 

 femoribus posticis dimidio fuscescentibus. Long. If lin. 



Hah. Tairua. 



Macratria is an almost cosmopolitan genus, but is not found 

 in Europe, nor, so far as I know, in Australia. This is the 

 smallest species that has come under my notice.
