and a neic fjenas of Cossonides. 13 



I have (as remarked above) given a new generic name 

 to this species; its chief structural characters are as 

 follows. Body clothed with fine hairs ; rostrum stout, 

 moderately long, subcylindric ; eyes moderately developed; 

 funiculus of antennas composed of five joints, all of Avhich, 

 except the basal one, are small and slender; the 2nd, how- 

 ever, being a little longer than the following ones; insertion 

 of antennas near middle of rostrum. Scutellum small but 

 distinct. Front coxas only very narroAvly separated, but 

 middle and hind ones broadly distant. Metasternum very 

 elono-ate : 1st and 2nd ventral seo-ments elono-ate. Legs 

 feeble, with slender feeble, linear tibias, whose apical uncus 

 is very small. Tarsi small, 4-jointed, 1st and 2nd joints 

 small and short, 3rd rather larger, with slender and short 

 lobes.

 opaco, dense fortiterque sed parum profunde punctato, 

 medio versus basin indistincte depresso ; elytris minus 

 profi-Uide striatis, striis fortiter punctatis, interstitio 2° ad 

 apicem paululum acute elevato; corpore subtus sat fortiter 

 punctato ; coxis anterioribus valde distantibus. Long. 

 1| mm. 



This species on account of its colour, sculpture and 

 pubescence, bears a superficial resemblance to Sericotrogus 

 subcenescens ; but it is really extremely distinct therefrom, 

 the rostrum is shining and but little punctate, and differs 

 in structure from that of S. suhcBnescens, its basal part 

 being much more constricted ; it has also the front coxas 

 much more widely separated. 



I have seen but a single individual, which I had formerly 

 put aside as a very small variety of S. subcenescens. The 

 specimen is from Auckland, and was sent either by 

 Captain Broini or Mr. Lawson ; probably by the former.
