tures moderately lai-ge and not very distant ; interstices wider 

 than punctures, the alternate ones acutely ridged. Three inter- 

 mediate segments of abdomea straight. Posterior _/e;«or« scarcely 

 passing penultimate segment; claw-joint exserted for less than 

 half its length. Length 3, rostrum 1; width 14 mm. 



Ilab.—W.A. : Gerald ton. 



Much the build of the preceding species, but with a shorter 

 claw-joint and different clothing. 



Lyb.eba parvicollis, n.sp. 



Red; sterna in places feebly tinged with piceous. Clothed with 

 ochreous-yellow and creamy-white scales, the shades of which, 

 especially on the prothorax, insensibly run into each other. 

 Scutellum, and a small space surrounding it on the elytra, 

 glabrous. Elytra with two distinct, but narrow and very 

 irregular transverse chocolate-brown fascife, interrupted at suture, 

 the 1st moderately close to base, the 2nd bej^ond middle; suture 

 with ochreous-yellow scales, scarcely interrupted; the creamy 

 spots rather larger between fasciae than elsewhere. Under 

 surface and legs with whitish scales. 



Rostnnn parallel-sided and highly polished, punctured at sides 

 of base only. Scape inserted nearer base than apex of rostrum, 

 considerably shorter than funicle; of the latter the 1st joint is 

 slightly but noticeably longer than 2nd. Prof hoi' ax densely 

 punctate. EUjtra about once and one-third the width of pro- 

 thorax ; punctate-striate, punctures apparently oblong ; strite 

 narrow; interstices considerably wider than strise, neither alter- 

 nately raised nor ridged Three intermediate segments of ahdo- 

 meii drawn backwards at sides. Posterior femora terminated 

 almost level with apex of penultimate segment; claw-joint exserted 

 for less than half its length. Length 3^, rostrum \\; width 2 mm. 



Hah. — W A : Swan River. 



In this species the head and prothorax are smaller and the 

 elytra larger than is usual. My unique specimen was captured 

 by means of the sweep-net.
