typical Lag rice. Diacalla differs from this genus, inter alia, in the 

 form of the head and prothorax, in the shorter antennae, in the 

 greater length and cultriform shape of the external maxillaiy lobe, • 

 in the longer and cylindrical labial palpi, &c. &c. The spines on the 

 anterior tibiae are almost hidden by the pubescence. 



Ictistygna vetula. 



I. fusca, elytris pedibusque rufulis. 



Hab. New South Wales. 



Dark brown, with a thin greyish pubescence, mixed with long erect 

 hairs ; head and prothorax covered with coarse crowded punctures ; 

 scutellum quadrate, with a close silvery pubescence ; elytra nearly 

 twice the breadth of the prothorax at the base, dull reddish, shining, 

 coarsely punctate, the punctures deeply impressed and nearly con- 

 tiguous, with the intervals very rugose ; body beneath reddish brown 

 or dark brown, with a greyish pubescence ; legs reddish, pubescent ; 

 antennae about half the length of the body, the second joint a little 

 shorter than the third. Length 5 lines. 



Ictistygna adusta. 

 I. nigra, elytris pedibusque rufulis, tarsis anticis quam in praecedente lon- 



gioribus. 

 Hab. New South Wales. 



Smaller, And more slender than the former, wdth the head, prothorax, 

 and antennae black, the second joint of the antennae much shorter than 

 the third, the anterior tarsi longer and narrower, and the anterior tibias 

 less spined on their outer edge. Length 2| lines. 



Efciodes [ Anthribidae] . 

 Caput infra oculos paulo latius ; rostrum transversum, antice truncatmn ; 

 scrobe magna, rotundata. Antenna maris corpore plus duplo longiores, 

 art. prime bre\i crasso, secundo elongato-obconico, reliquis ad nonum 

 capillaribus, apice nodosis, duobus ultimis brevibus clavam formantibus. 

 Oculi mediocres, laterales, armati. Prothorax subcylindricus ; carina 

 basi baud parallela, et ad latera vix continuata. Elytra cylindrica, 

 prothorace paulo latiora. Pedes mediocres ; tarsi art. basali sequenti- 

 bus duobus simul sumptis baud longiore. 



Most of the characters of this genus are those of Exillis^, after 

 which it may be ranked. It has, however, the head broader below, 

 so as to form a strong margin round the scrobe, the second antennal 

 joint elongate and obconic, the ninth entering less decidedly into
