LiMONIATES VENTRALIS, D.Sp. 



J". Reddisli-eastaneous, elytra slightly paler, appendages dis- 

 tinctly paler, abdomen and metasternum darker, sometimes almost 

 •black. With very short, pale pubescence. 



Head (including mandibles) distinctly transverse; base 

 feebly notched, middle feebly longitudinally ridged; with 

 a shallow depression, but not foveate, on each side 

 of ridge. Antennse passing middle of prothorax, eleventh 

 joint large, briefly ovate and decidedly wider than tenth, 

 which is distinctly transverse. Prothorax feebly transverse, 

 scarcely, if at all, wider than head; with traces of a median line 

 only near base, each side of middle near base with an impressed 

 line dilating towards the side; with numerous and small but 

 fairly distinct punctures. Elytra not as long as wide, sides and 

 shoulders rather strongly rounded; with four small basal foveas; 

 dorsal striae lightly curved, deep at base and traceable almost to 

 apex; punctures rather more distinct than on prothorax. Meta- 

 ^<e?*?iMm strongly sulcate along middle from base to apex. Lower 

 surface of abdomen with a longitudinal impression about the 

 length of metasternum, the impression almost filled by a ridge 

 covered with fine golden setae; apical segment with a feeble fovea. 

 Legs moderately long; femora stout; four hind tibise spinose at 

 apex. Length |-4 mm. 



9. Differs in having metasternum feebly impressed and only 

 posteriorly, abdomen simple and tibife unarmed. 



Hab. — W. Australia : Vasse River; numerous specimens in 

 flood-debris(A. M. Lea). 



It is with some doubt that this species is referred to Limoniales, 

 as the impressions of the head and prothorax are so different from 

 those of the other species known to me; but the curious meta- 

 sternum and abdomen of the male render the species remarkably 

 •distinct. 



Macroplectus quadrifoveatus, n.sp.
