Mr. J. Walton on the genera Pissodes^ Hypera, ^c. 301 



eyes oviform, rather prominent; rostrum as long as the thorax, 

 lound, thickish, bent, and closely punctulated. Antennae inserted 

 near the apex of the rostrum in the male, and between the mid- 

 dle and the apex in the female, testaceous ; clava oblong-ovate, 

 obscure, testaceous. Thorax as broad in the middle as long, a 

 little more narrowed before than behind, moderately dilated and 

 rounded at the sides, rather convex above, closely and delicately 

 punctulated ; clothed with brown scales, a large rhomboidal pale 

 patch on the disc, and a broad whitish line on each side. Elytra 

 ample, oblong-ovate, shoulders very prominent, obtusely rounded, 

 punctate-striate, interstices rugulose ; thickly clothed with conico- 

 ovate scales, two subquadi*ate velvety black spots at the base, a 

 short white line on the scutellum, an oblique pale vitta down 

 each elytron, broadest on the shoulders, spotted with black on the 

 margins, and united beyond the middle to a transverse irregular 

 silvery white fascia, which is joined to a subtriangular velvety 

 black one. Legs moderate, rufo-testaceous, pubescent ; tarsi 

 elongate. Length If — 2 lines. 



Exclusively of the six-jointed funiculus to the antennae, this 

 insect is well characterized, by the conspicuous velvety black 

 fascia on the elytra, combined with the conico-ovate scales. 



Varieties occur with gray or silvery white scales, and these 

 being more subject to abrasion, are frequently found partially de- 

 nuded, and the spots and stripes more or less obscure ; others 

 occur of a brassy yellow, with the markings distinct, and the body 

 and legs pale testaceous. 



Many specimens of this insect were found on Erodium cicuta- 

 rium on the Chesil Bank, Isle of Portland, in June, by Mr. Wol- 

 laston, to whose indefatigable industry, we are indebted not only 

 for this, but for many other additions to the British fauna ; sub- 

 Bcquently found in the same locality by Mr. Bowerbank and 

 myself in September.

 vate, extending beyond the eyes ; funiculus with the two basal 

 joints somewhat long, subclavate, remainder rotuudate ; clava
