298 NEW SPECIES OF AUSTRALIAN COLEOPTEEA, 



of tubercles irregularly punctate and oljsoletely granulate; six 

 lateral rows of punctures of which only one is distinctly marginal, 

 the upper row irregular and touching tubercles, posterior declivity 

 irregularly punctate and obsoletely granulate; apex semicircularly 

 emarginate and each obtusely mucronate. Sterna sparsely punc- 

 tate. Two basal segments of abdomen with shallow irregular 

 impressions, except at sides of suture where they are distinct, 

 2nd segment irregularly feebly obliquely ridged at apex, apical 

 segment with an outer row of coarse punctures, middle with a 

 foveate elevation. Legs moderately long, thin, tarsi not padded.

L^MOSACCIDES. 

 L.'EMGSACCUS ARGENTEUS, n.sp. 



Entirely black. A median stripe on prothorax, a short oblique 

 spot on each elytron conjoined at base (lying on the 1st and 2nd 

 interstices, the two conjointly subobcordate), a small spot on each 

 side of apical abdominal segment, clothed with silvery-white 

 scales; a few whitish scales at apex of elytra, on sterna, and 

 between eyes. 



Eyes large, almost touching; rostrum long, shining, cylindrical, 

 feebly curved, punctate* at base and apex, almost impunctate in 

 middle; 1st joint of funicle nearly twice the length of 2nd, club 

 almost as long as funicle. Prothorax subquadrate, slightly 

 narrowed in front, and with a feeble median impression, base with 

 an impression on each side. Scutellum transversely triangular. 

 Elytra with angles slightly rounded at base and apex, each feebly 

 convex in consequence of a sutural depression, interstices flat, 

 feebly granulate. Abdomen, with meso- and metasternum, 



* 111 the species here described I have not considered it necessary to give 

 the puncturation of any parts but the rostrum, as it is much the same in 

 all and therefore of little nse for identification.
