10-^ KEVISIONAL NOTES ON AUSTEALIAN CABA HI D.f-:,U., 



Genus S T E G a n o m m a. 



Macleay. Proc. Linn. J<oe. X. S. ^Yales, {'2) ii. 1SS7, p. 133. 



The granulate lateral channel of the elytra, and the mentum 

 concealing the base of the maxilhv, while the buccal fissure runs 

 narrowly back and divides the submentuni from the paragen^v. 

 indicate the place of Sfe(fauo)nma to be in the subtribe Scaritides: 

 it seems to lead towards the CUvhiini. 



I supplement Macleay's description by the following note on 

 the single recorded species of the genus : — 



Steganomma poecatum. Macleay. 



Proc. Linn. Soc. N. S. Wales, (2) iii. 1S87, p. 133. 



Base of maxillae concealed by mentum. Buccal fissure extend- 

 ing backwai*ds and dividing submentum from the small paragems. 

 Labial j>alpi with p>enultimate joint bisetose. Eyes very small 

 (not p>erceptible from abo^■e), placed on anterior declivity of the 

 j)rojectiiig orbits in the angle formed by the anterior margin of 

 the orbits and the supra-antenual plates.* Antenn:^ moniliform. 

 four basal joints glabrous. Prothorax a little wider than head 

 (3 6 X 4-1 mm.), widest just behind anterior angles: anterior mar- 

 gin truncate; base wide, not lobate; each lateral channel with 

 four setigerous punctures on curve of posterior angles, and three 

 similar punctures on anterior third. Elytra widest a little behind 

 middle (7x4 mm.), strongly and evenly convex, lightly rounded 

 on sides; six wide crenulate sulci on each elytron: interstices. 

 roundly convex, sixth bearing the fine seventh stria, eighth inter- 

 stice (between linear seventh stria and granulate margin) very 

 narrow; marginal channel wide, closely granulate: lateral border 

 narrow: base abrup>tly and deeply declivous to peduncle, bordered 

 on each side, — the border forming a short erect humeral tooth at 



"" The very small hidden eves call to mind Horn's note that the minute 

 European species, Eeicliia luciuiga, Saulcv, a Clivinid, was " the only 

 known member of the Carabinw with the eyes so reduced as to be with diffi- 

 ciilty observed" (Trans. Amer. Em. Soc. xi. ISSl. p.lSS).
