58 H. 1. Carter: 



Alcmeonis excisipes, n. sp. 



Elongate, navicular, upper and lower surface bronze purple, with 

 short white pubescence, this scanty above, denser beneath, basal 

 joints of antennae, legs and tarsi pale testaceous, with knees black 

 and apical two-thirds of antennae fuscous. Head densely and 

 rather coarsely punctate, eyes large and distinct, epi stoma arcuate, 

 antennae with joint 1 thickened, 2 short. 3 longer than 4, 4-8 sub- 

 equal, somewhat filiform, but thickened at outer end; 9-11 thinner 

 than 10, but of some length, 11th finely pointed. Prothorar oblong, 

 depressed, slightly narrower than head, feebly narrowed at apex, 

 posterior angles slightly obtuse, rather closely punctate and a little 

 rugose, a faint medial line terminating in a large foveate depres- 

 sion before the base, the latter slightly transversely ridged. 

 Scutellum very transverse. Elytra wider than protborax at base, 

 shoulders squarely rounded, sides tapering rather straightly towards 

 apex, striate punctate, the seriate punctures irregular in size and 

 somewhat transverse, intervals convex and strongly punctate. 

 Sternum closely and strongly, abdomen very minutely punctate, 

 posterior intercoxal process narrowly triangular, abdomen with 6 

 segments in <?, 5 in ?, the 4th shorter than the rest; the 6th 

 segment in the 3 is long, divided into two pointed lobes, with 

 a triangular excision in the middle. Legs long and thin, femora 

 much less expanded than in A. punctulaticollis, Blackb., and with- 

 out any angulation or tooth, tibiae of $ hollowed on the inside, 

 with a large curved excision about the middle. Tarsi lamellate 

 on the penultimate joint in posterior, on the two penultimate joints 

 in the other feet. 



Habitat.— Dorrigo (R. J. Tillyard). 



Compared with A. punctulaticollis, Blackb., this species shows 

 the following differences : — Colour, unicolorous bronze-purple, the 

 purple predominating above the bronze beneath, with pale testaceous 

 legs and black knees. Form flatter than usual, the femora unden- 

 tate, the post tibiae of 3 excised on inside, the sixth segment of 

 abdomen long and divided throughout. In the 3 of A punctulati- 

 collis, Blackb., the sixth segment of abdomen is shorter, and not 

 divided throughout, while its post femora are strongly thickened 

 and dentate.
