Mr. J. Walton on the genera Pissodes, Hypera, ^c. 301 
eyes oviform^ rather prominent ; rostrum as long as the thorax, 
round, thickish, bent, and closely punctulated. Antennse 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 subquadrate 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 antennse, 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- 
sequently found in the same locality by Mr. Bowerbank and 
myself in September.
