394 DESCRIPTIONS OF XtW .SFECIES OF AUSTRALIAN COLF.OPTERA. 



tiun the larfTcr one has the elytra Havous, except for a narrow Ijla.-k hiusal e.ly'mg, 

 and a short infuseation of the suture at the base; but the smaller one has about 

 halt' of the elytra l)lack or infuscateil, tlie dark part not sharply defined on its 

 edges, but extending from each shoulder to the suture beyond the middle, so that 

 the sides and apex are widely flavous. 



DlTliOl'IUrS IIETALLICUS, n . sp . 



^_ Coppery, prothurax sometimes with a greenish gloss; labruiu, basal half 



of antennae (the club infuscated), tips of elytra, abdomen (except part of base), 

 legs (the claws infuscated) reddish-llavous. Head, under surface and legs 

 sparsely pubescent. 



Head with crowded and more or less obliquely confluent punctures; median 

 line rather shallow. Eyes widely separated. Prothorax at apex abimt as wide 

 as the median length, sides increasing in width to base; with dense and rather 

 sti'ong punctures, the sides conspicuously strigose. Elytra oblong; with rows of 

 rather large punctures, at the sides set in rather deep striae. Length [S, V), 

 2—2.5 mm. 



?. — Differs in being somewhat more robust, eyes more widely separated, pro- 

 thorax and legs slightly shorter, and abdomen larger, with a large, round, deep, 

 apical fovea. 



//a6.— Tasmania: Sheffield (il. 11. D. Griffith's No. 1204). 



The prosternum is usually coppery, the niesosternum and metasternuiu bronzy ; 

 the dark part of the abdomen is sometimes semicircular, and almost confined to the 

 intercoxal process; the pygidium is entirely pale. The median line of the head is 

 rather shallow, but is very conspicuous on account of the converging punctures; 

 the front legs of the male are no longer than the hind ones. The description of 

 D. apiciflavus (from "Nouvelle Hollande") agTees in most respects with this 

 species, except that of the prothorax, which is noted as "parce et subtiliter pune- 

 tulato, lateraliter substrigoso." Specimens from New South Wales (Gosford, 

 Sydney, and .Jenolan) agree in all respects with its description (except that some 

 of them are larger) ; the present species differs from these in having the prothorax 

 with dense, and, for the genus rather strong punctures, with the sides densely 

 strigose; it has also larger elytral jnuictures, is narrower and more cojipery (alino.-t 

 golden) than brassy. It is the only species now known from Tasmania, witii the 

 elytra tipped with red, althougii the red is not always snari)iy limited; I). rir'uViae- 

 neus has the prothorax wider and very ilifiVicntly sculptured. 



DiTROPIDUS INSIGNIS, n . sp . 



5.- — Deep violet-blue, labrum. i>alpi and p.iii nl' antennae re(l. Tender surface 

 and legs with sparse pubescence. 



Head with crowded and sharjdy ilcHncd ]iiuictur<'s. lic'cuiiiiug i-iigosc on 

 clyi)eus, median line shallow and irregular. Kyes widely separated. I'mllnirar 

 at base scarcely twice as wide as tiie median length, sides strongly rounded; with 

 crowded, longitudinally confluent punctures, excejit on scutellav lobe, where they 

 are separately impressed. Eli/tra briefly suboblong; with rows of not very large 

 but deep punctures, becoming larger and set in fairly deep striae on the sides; 

 interstices with sparse punctures, except posteriorly, where they are moderately 

 dense and rugose. Under surface with rather ilense and coarse punctures; ab- 

 domen with a large, round deep apical fovea. Length, 4.25 mm.
