but the Rev. T. Wood has found them feeding by night in large numbers ; 
the attacked crops may be known by having the leaves eaten and 
notched at the edge ; an account of various remedies suggested will be 
found in Miss Ormerod’s Manual of Injurious Insects, p. 133; the pea- 
crops suffer most in their early stages; the best method, therefore, to 
prevent the loss of the crop is to ensure as quick a growth as possible, 
and this may be done by providing “a good seed bed, friable, sufficiently 
moist, and rich in available plant-food, which way be obtained to a 
certain extent by peas following cabbage or root crops in rotation ; in 
garden cultivation, besides the liberal supply of manure needed to run 
on a healthy growth, it has been found to answer well to put a little 
broken turf and wood ashes along the drill, sow the peas on this, and 
cover them with a little more of the same”; a good depth of coal ashes, 
placed at sowing time along the drills on a clayey loam, has been found 
to answer well; the attacks are worst in dry weather; it is evident, 
therefore, that keeping the plants damp is distasteful to the beetles and 
encourages healthy growth ; a dressing of lime or soot given to the wet 
plants is an easily applied and generally effective remedy. 
The British species may to a certain extent be distinguished by the 
following table, but a careful study of the detailed descriptions, and, if 
possible, a comparison of authentic types, is necessary, if they are to be 
determined with any accuracy. 
I. Scutellum very conspicuous, with two white tufts 
of hair which diverge in front and cause it to 
appear emarginate; scrobes feebly curved; elytra 
long, with the alternate interstices subconvex ; 
length 6-9 mm. . . S. @RIsEvs, F. 
II. Scutellum not conspicuous and. not appearing 
emarginate in front; scrobes more stronglycurved, 
i, Elytra, if viewed sideways, with very distinct 
raised seta. 
1. Thorax very closely punctured, convex and 
arched, forming a distinct angle with the ely- 
traif viewed sideways, sides strongly rounded; 
eyes prominent ; outstanding sete very long. S. REG@ENSTEINENSIS, Herbst. 
2. Thorax not convex and arched, almost on the 
same level with the elytra. 
A. Eyes flat; thorax with large diffuse punc- 
tures and with the sides moderately ore 
rounded . . S HISPIDULUs, F’, 
B. Eyes very pr ominent; “thorax coarsely pune- 
tured, with the sides slightly rounded. 
a. Apex of scrobes plainly visible if viewed 
from above; punctuation of thorax 
coarser; scales of elytra very narrow; 
eyes extremely prominent. . . . . WaTERHOUSE!, Walt. 
b. Apex of scrobes not or scarcely visible if 
viewed from above; punctuation of thorax 
closer and a little finer; scales of elytra 
round; eyes very prominent, but less so 
than in the preceding species. . . . . S. cRINITUS, Herbst.
