Acalles perpusillus.

 illolincatim punctulato ; prothoracc latitudine long^tudini aiquali, 

 ant ice coiistricto, supra vage punctato ; clytris brevitcr ovatis, 

 prothoracc latioribus, humeris obsolctis, supra modico convexis, 

 fortiter seriatim punctati.s, intcrstitiis latis, laevigatis ; corporo 

 infra vage punctato; abdomine scgmentis duobus basalibus valdo 

 ampliatis, tribus ultimis pallidis; pedibus validis. Long. 1 lin. 



Hab. Tairua. 



A very small pitchy-brown species. 



ACALLOPAIS. 



Rostrum validura, apiccm versus gradatim incrassatum ; scrohes late- 

 rales. Antt'tuKe pone medium rostri iusertac ; scapus brevis ; 

 fKniadt'S ad clavam gradatim crassior. OcuU majusculi, grosse 

 granulati. Prothora.v basi latior. Scutellum nullum. Elytra 

 breviter subcordata. Rima pectoralis ampla, apicc cavernosa. 

 Femora crassa, infra canaliculata ; tihicp. rectae, apicc uncinate ; 

 tarsi articulo penultimo bilobo ; xingnes divcrgentes. 



The pectoral canal is large, terminated by the raised border 

 of the mesosterniira, 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 bet^veen the two being too gi-adual 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, squamosua, squamis erectis 

 numerosis adspcrsus ; rostro nitide fusco, capita vix longiore ;

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

 plissimis. Long. \\ lin.

JIab. Tairua. 



}[acratria 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.
