as it seems common to all that are at present known, I change' it at 

 present to pollens. It was received from Van Diemen's Land in 1839. 



Uracanthus marginellus. Uracan.fusco-brunneus thorace albo- 



linealo, elytrisque brunneo marginatis. 

 Totum corpus sujrra tomentoswn, capite porrecto et inter oculos

 utrinque panto. Elytra albo-pubescentia marginibus brunneis 

 apicibus abrupte truncatis, spint.s parum prominentibus. Corptu.s 

 infra concolor, femoribus compressi.i. 

 Long. lin. 9 ; lat. lin. 1^. 



I received this insect from Captain Roe, of the Swan River. In 

 form it approaches a singular genus named Stephanops by Mr. Shuck- 

 hard ; it is however decidedly an Uracanthus, and there can be little 

 doubt that Stephanops Nasutus of the above author belongs to my 

 section of the cone-necked-shaped Stenochorida.

The above insect I have received from various parts of New Hol- 

 land ; as it is accurately figured, I have not given very full generic 

 details. I must remark, however, that in the sexes of this genus 

 the antennse vary very considerably, in one instance exceeding the 

 length of the body, whilst in the other sex they are shorter than 

 the elytra. These Longicorn beetles also vary much in size, 

 which is a remark that appears to apply to most of the Cerambycidce 

 of New Holland. Can the long drought which sometimes prevails 

 in this country be regarded as the cause of dwarfishness, which is 

 certainly one of the striking features of the Coleoptera of Au- 

 stralia ?
