loeality is Deal sandhills where large numbers have been taken; Sindwich; Ports- 
mouth district; Swansea; Devon; “ Isle of Thanet and in Norfolk ; more common 
in Scotland” (Stephens) ; Scotland, maritime, extremely local, Forth and Clyde 
districts. 
H. arundinis, Payk. Black, densely clothed with compact greyish- 
yellow or reddish-brown scales, which are rather brighter at sides of 
elytra and cover both the upper and the underside; thorax with three 
lighter lines; head convex, with a longitudinal impression between the 
eyes; rostrum rather long, pubescent, with the apex glabrous ; antennz 
black with the base pitchy; thorax subcylindrical; elytra scarcely 
broader than thorax, with faint punctured striz; legs black, sparingly 
pubescent. LL. 7-7 mm. 
On Sium latifolium ; the larva has been observed on this plant and on Siwm 
angustifolium in France; very rare; ‘‘ taken in marshy places near Exeter, and I 
believe in Norfolk,’ Stephens; Dover (Hall); Titchfield River, Portsmouth (Mon- 
creaff); Dr. Power has a single specimen in his collection labelled “ Lewis, 1861.” 
Hi. rumicis, L. Black, variegated with rather shining ashy-white 
and yellowish-brown scales ; head thickly punctured, vertex squamose ; 
rostrum almost straight ; antennz dull ferruginous, with the club darker ; 
thorax subcylindrical, with two fuscous longitudinal bands; elytra with 
fine punctured striz, thickly clothed with ashy-white and brownish 
scales, with a subquadrate spot at scutellum, and some minute scattered 
dots, fuscous or black, a patch on each elytron behind middle near 
suture being immaculate ashy-white or at ail events lighter than the 
rest of the elytra; legs pitehy. L. 45-55 mm. 
Male with the anterior tibiz curved, the abdomen impressed at base, 
and the club of the antenne elongate. 
Female with the anterior tibie almost straight, the abdomen convex 
at base, and the club of the antenne less elongate. 
On species of Rumew (dock), also on Polygonum aviculare; generally distributed 
and common throughout the greater part of the kingdom; in some districts, how- 
ever, it appears to be local; Mr. Bold records it as rare in Northumberland and Dur- 
ham, but it appears to be not uncommon in Scotland as far north as the Moray 
district. 
EE. pollux, F. (adspersa, F.). Black, variegated with ashy-white or 
yellowish-brown scales; head finely punctured, pubescent; rostrum 
glabrous at apex, scarcely curved ; antenne red or ferruginous, with the

the prevailing tint being sometimes grey and sometimes a warm 
yellowish-brown; this is also the case with other allied species. L.
