line, but it is quite absent from the five others before me. The 

 Swan River specimen has the sterna and femora quite black. In 

 some respects, the female is close to the description of Lycaon 

 ater, but the fourth joint of the antennse is no shorter than the 

 fifth, and the prothorax has a conspicuous median line. The 

 types were taken in cop. 



Dyscolocerus rubriventris, n.sp. 



(J. Black ; abdomen and legs bright red, antennae reddish, 

 becoming darker towards base, with the basal joint black. 

 Clothed with blackish and ashen pubescence, becoming palei-and 

 more uniform on the undersurface. 



Antenufe with second joint slightly longer than fourth, third 

 slightly longer than fourth and fifth coml)ined, fourth-eighth sub- 

 equal in length, ninth-eleventh as long as first seven combined, 

 ninth slightly wider than the following ones, almost as long as 

 the four preceding combined, about one-third longer than tenth, 

 and about two-thirds the length of eleventh. Length, 5J-6mm. 



9. Differs in having the fourth-eighth joints of antennie slightly 

 wider than long, the ninth-eleventh scarcely as long as the seven 

 preceding combined, and the eleventh very little longer than the 

 ninth.

The description of the sculpture of the preceding species, 

 except of the antenna?, applies exactly to the present species, but 

 besides the conspicuously red abdomen (in striking contrast to 

 the black sterna) it differs from that species in having the three 

 terminal joints of antennae longer (in both sexes) and the fourth- 

 eighth joints of the antennte of the male much less conspicuously 

 transverse. 



DiCTYEUCNEMIS, n.g. 



Head moderately large, antennary sockets comparatively small 

 and widely separated. Mandibles large, prominent, strongly 

 curved, their hind outline straight. Antennae thin and rather 

 long. Prothorax moderately transverse, hind angles small, pro- 

 duced slightly outwards but not backwards, and not embracing 

 the elytra. Scutellum subquadrate. Elytra strongly convex,
