Habitat.— New South Wales: Blue Mountains, (Dr. E. W. 

 Ferguson). 



In the Proc. Linn. Soc. N.S.W., Vol. xxxvi., (3), p. 455, Mr. 

 A. M Lea records Blue Mountains, N.S.W., as a new locality for 

 ScMstodactylus hrevipennis. Lea, on the strength of a specimen in 

 Dr. Ferguson's collection. This specimen is the one upon which I have 

 founded the above description. It was gummed right side up upon a 

 card so that none of its undersurface or palpi were visible. As the 

 uppersurface is almost identical with that 'brevipennis it is easy to 

 see how Mr. Lea mistook it for that species. The discovery of 

 armipectus so markedly resembling brevipennis in the characters of 

 its uppersurface, led me to wonder if this specimen might also have 

 an armed prosternum. On floating it off and cleaning it, I found 

 that it was still another new species. It will thus be seen that for 

 positive identification of a Schistodactylus it is absolutely essential to 

 examine the characters of the undersurface. 



For this interesting species together with many other fine 

 Psclaphids, I am indebted to the generosity of my friend, Dr. E. W. 

 Ferguson. 



Type in author's collection. 



The genus now comprises four species, viz., pJiantasma, Raff., from 

 Western Australia, brevipennis, Lea, from Tasmania, armipectus, n.sp., 

 from Victoria, and foveiventris, n.sp., from New South Wales. These 

 may be tabulated as follow: — 



A. Apical joint of palpi simple at extremity. 



pUantasma, Raff. 

 A.A. Apical joint of palpi noi simple at extremity. 



B. Apical joint of palpi with a spine and a strong seta 



at extremity. 



C. Prosternum unarmed. brevipennis, Lea. 



C.C. Prosternum armed. armipectus, n.sp. 



B.B. Apical joint of palpi with a spine, but no strong 



seta at extremity. foveiventris, n.sp. 



Paijmbolus armatipes, n.sp. 



(J Reddish castaneous; legs, palpi and elytra slightly paler; 

 with somewhat sparse lightly golden pubescence, shorter and more 

 decumbent on prothorax than elsewhere. 



Head strongly convex, very slightly longer than broad, with two 

 small round foveae, one on either side close to eye, and a discal fovea 

 a little in advance of these; midway between discal fovea and antenna! 

 ridges with a deep transverse fovea; inter-antennal region raised; 

 eyes moderately prominent; puncturation sparse and minute; antennae 

 moderately long, joint 1 cylindric, viewed from side longer than 2 

 and 3 combined, 2 slightly longer tnan 3, 4 and 5 much broader, the 

 latter being a little longer and broader than the former, both widened 

 internally, 6, 7, 8, subequal and narrower than 5, 9 and 10 about 

 equal in length to 5, but wider, the latter lightly wider than the
