on sides but rather sparse elsewhere; median line rather feeble, 

 a vague impression on each side of middle towards base. Elytra 

 comparatively wide, slightly dilated posteriorly; with dense and 

 minute, but clearly defined punctures, and with remnants of 

 feeble ridges. Length, 10-12 mm.

The second joint of antennae is almost as long as the third, so 

 that the species should be referred to "A" (in Blackburn's table), 

 its position in which would .be with Z. tenuicornis, which has 

 differently coloured undersurface and legs, punctures of head and 

 prothorax, and the shape of the latter different. In general ap- 

 pearance, it is close to Z. pallicoIo)\ but the eyes are decidedly 

 narrower, prothorax wider, with smaller punctures; elytra wider, 

 with smaller punctures (but still sharply defined), and more of 

 the legs pale, etc. 



Family CURCULIONID^. 



Perperus ziczac, n.sp. 



Of a dingy reddish-brown, in places almost black. Densely 

 clothed with pale brownish-grey scales, becoming almost white, 

 but with a metallic lustre on undersurface and legs; elytra with 

 darker markings. In addition, with fairly numerous, depressed 

 or subdepressed setae. 



Head with punctures normally concealed. Rostrum rather 

 long, with two grooves along middle, sublateral sulci fairly deep 

 but partially concealed. Antennae thin, scarcely extending to 

 base of elytra; second joint of funicle slightly longer than first. 

 Prothorax rather lightly transverse, sides strongly rounded, with 

 a moderately distinct but not continuous median groove; with 

 dense granules, some rounded but many oblique or transverse. 

 Elytra ovate-cordate, widest across middle, where the width is 

 almost twice that of prothorax; with regular rows of large, par- 

 tially concealed punctures; interstices regular and evenly convex. 

 Basal segment of abdomen slightly longer than second and third 

 combined, second almost as long as third and fourth combined. 

 Xe^s rather long. Length, 11-1 3 mm.
