A Ltsfralum und Tdsum iiyti h (.'olcopffm. 59 



long stramineous hairs ; clothing on head and prothorax someAvhat 

 shorter and darker, on the latter becoming dense on sides, and on 

 the former forming a feeble fascicle on each side of base. 



Head (excluding neck) distinctly transverse, flattened between 

 antennae. Eyes of moderate size and very prominent. Antennae 

 lung and thin ; club four-jointed. I'rothnran slightly wider than 

 long ; base with a strong transverse impression, with a foveate ex- 

 pansion at each end. Elytra modeiately long, somewhat depressed, 

 base slightly wider than prothorax, sides evenly rounded and widest 

 across middle. Abdomen with fourth segment conspicuously armed. 

 Af//s moderately long; hind coxae rather distant; femora stout, 

 especially the fnmt pair. Length Ij mm. 



Hah.- — Tasmania : Devonport, from a nest of Ectatoini/ia iiictal- 

 licuin, Stanley, in tussocks at summit of ■" Nut "' (A. M. Lea). 



The type has its neck exposed, and this is seen to be castaneous. 

 The antennae at a glance appear to have the joints subcontinuous in 

 width, but the seventh, although distinctly longer and wider than 

 the sixth, is less than half-way in width between that joint and the 

 eighth ; the eleventh is not much shorter than the ninth and tenth 

 combined. The prothorax has two rather large transverse foveae, 

 connected together by a short impression, but they could quite fairly 

 be regarded as expanded portions of the impression. Each side also 

 is obliquely imj^ressed, but the impression is invisible from above, and, 

 as in many other species, is more or less obscured by clothing. 



The fourth segment of the abdomen, towards each side, has a long, 

 and somewhat obtuse, reddish tooth, projecting backwards at an 

 angle of about 45 degrees ; each is about half the length of the hind 

 tibiae, and the two are connected basally by a semitransparent, mem- 

 ijranous tiaj), that is thickened in the middle, causing an appearance 

 as of a much smaller median tooth. 



*Scydrnaenus (jlabripennis, Lea. 

 There are two specimens of this species in the Macleay Museum 

 fiom the Tweed River, and five in my own from the Clarence.! 



*Scydmaenus colobojjsis, Lea. 



Recently taken from nests of Amhlyopone. auatralis. 



A specimen from Dunorlan. from a nest of the original ant, differs 

 from the tyj>es in being considerably darker, almost piceous. 



A specimen from an unnoted ants" nest at Sea Lake- sent by Mr. 

 Goudie, differs from the types in having the impression at base of 

 prothorax narrower across the middle, but I can find no other dis- 

 tinctions.
