NATALIS. 



N. Leai, Blackb. In describing this species (Tr. R S., 8. A., 

 1899, p. 31) I referred to its agreement in non-generic charac- 

 ters with the description of Opilo floccosus, Schenk. (published in 

 1898) but pointed out that as Schenkling especially mentioned 

 his insect having the securiform maxillary palpi and bifid tarsal 

 lamellfe of an Opilo the two species must be distinct. I find, 

 now, that Schenkling has published a note (Deutsche Ent. Zeitsch., 

 1903, p. 19) to the effect that he han examined more specimens of 

 O. floccoswi and observes the characters referred to above to be 

 in reality as in Xatalis to which genus his species must therefore 

 be transferred. This of course makes it identical with my 

 ^V. Leai ; and the synonymy will be as follows 



Natalis ( Opilo ) fioccosv,s, Schenk.

EXANGELTUS. 



E. gracilior^ sp. nov. Opacus ; nigro-piceus, antennis palpis 

 pedibus et corpore subtus plus minusve rufescentibus ; 

 anguste elongatus ; sat convexus ; setis brevibus subtilibus 

 minus crebre vestitus ; prothorace minus fortiter transverso, 

 antice parum emarginato (quam postice sat angustiori), 

 longitudinaliter confertim subtilius strigato, lateribus antice 

 leviter arcuatis postice fere reccis, angulis anticis bene deter- 

 minatis leviter obtusis posticis subacutis retrorsum directis ; 

 elytris sat parallelis, quam prothorax sat latioribus, striis 

 circiter 17 crebre punctulatis impressis, harum puncburis 

 quadratis, interstitiis angustis (alternis vix prominentibus) ; 

 corpore subtus crebre sat fortiter punctulato ; antennis sat 

 elongatis; oculis magnis. Long., 4 I.; lat., 1| 1. 

 Considerably smaller than E. angustus, Blackb. It has longer 

 and more slender antennae, the 3rd joint of which is as long as 

 the 4th and 5th together, while the 10th and 11th together are 

 scarcely longer than the 9th ; the head is less depressed than in 

 E. angustus but (as in that species) the clypeus is not separated 

 from the front by any transverse furrow or noticeable suture; the 

 prothorax is considerably less transverse than that of E. angustus 

 and the longitudinal wrinkling of its surface is very much finer ; 

 on the elytra the intervals between puncture and puncture in the 

 striae are of the same height as the interstices between the stride 

 (except the alternate interstices which are very slightly promi- 

 nent) ; the setae of the dorsal surface are much finer and less 

 conspicuous. The tarsi are (like those of E. angustus) clothed 

 beneath with soft close pubescence. 

 S. Australia ; near Woodville.
