actually does not) extend to the abdomen. Seen from the sides, 

 the prothorax appears to be obliquely truncate from the apex to 

 the anterior cox^e so that the ocular lobes are really absent. 



Tlie position of the genus is by no means certain, but on account 

 of its elongated canal and exposed intermediate coxse it is placed 

 after Berosiris. 



MiCROBEROSIRIS EXILIS, n sp. 



Blackish-brown, antennfe (club excepted) and rostrum (base 

 excepted) paler. Densely and almost uniformly clothed (on 

 rostrum at extreme base only) with white scales that almost 

 completely hide the sculpture. 



Neod with dense concealed punctures. Rostrum long and thin; 

 with rather strong punctures on basal half, apical half shining 

 and lightly punctate. Prothorax feebly transverse, apex not 

 much narrower than base; with dense concealed punctures. 

 Elytra slightly wider than prothorax and but little more than 

 twice as long, shoulders rounded, sides parallel to near apex; 

 with series of concealed punctures; inter.stices regular. Under 

 surface with dense concealed punctures; pectoral canal terminated 

 almost at abdomen, but a feeble impression connecting it with 

 abdomen itself. Length 1^, rostrum |; width | mm. 



Hah — W.A. : Swan River. 



I have seen but one specimen of this minute insect, and in 

 preparing it for examination damaged the funicle of both of its 

 antennse; in consequence only the club and scape could be 

 described. Both genus and species, however, are remarkably 



distinct. 



Sympediosoma, n.g. 



Head rather small, moderately convex, partially concealed. 

 Eyes large, ovate, rather widely separated, coarsely faceted. 

 Rostrum rather long and thin, distinctly curved, sides distinctly 

 incurved to middle. Antennce rather thin; scape shorter than 

 funicle, inserted in middle of rostrum; two basal joints of funicle 

 elongate; club elliptic-ovate. Prothorax transverse, base bisinuate, 

 apex strongly narrowed, constriction feeble, ocular lobes obtuse. 

 Scutelhnn distinct. Elytra subcordate, not much (and not
