352 PHYTOPHAGA. [ Longitarsus. 
of a pale yellow testaceous colour, which, however, is variable, and is 
lighter when the insect is alive, with the antennez brownish towards apex, 
and an indistinct spot on posterior femora darker ; the mouth parts are 
also blackish ; thorax with very distinct margins, moderately convex, 
very finely punctured ; scutellum small, smooth ; Wings present ; elytra 
much broader than thorax, with the shoulders well marked and the 
sutural apical angles obtuse, finely punctured, the punctuation being 
much more obsolete in some specimens than in others. L. 2-3 mm. 
Male with the first joint of the anterior tarsi dilated, and the last 
ventral segment broadly foveolate, the fovea being impressed with a 
smooth line in middle. 
On Senecio jacobea (Ragwort) ; common and generally distributed throughout the 
greater part of the country. 
The colour of this species varies considerably, and is occasionally in 
extreme specimens reddish-testaceous or dark reddish; these specimens 
usually do duty for Z. rwtilus in our collections, from which species they 
may be known by their distinctly finer punctuation ; the variety does 
not appear to be named, and I would therefore propose to call it 
v. TUfesceiis. 
L. rutilus, Il]. Very closely allied to the preceding, but dis- 
tinguished by its much stronger and more evident punctuation, which 
on the elytra is disposed in striz near the base, and the longer and more 
slender first joint of the posterior tarsi ; from all ordinary examples of 
L. jacobee it may be known by its deep reddish colour ; the specimens 
I have seen are also rather smaller than is usually the case in the last- 
named species; the food plant also appears to be different. LL. 23-3 mm. 
On Scrophularia aquatica ; rare; the only specimens of the true 7. rutila that I 
have seen were taken by Mr. Moncreaff at Hayling Island, near Southsea ; it has also 
been recorded from Weybridge and Hastings. 
L. ochroleucus, Marsh, This species may at once be known by 
the very pale whitish testaceous colour of the upper side and the black 
apex of the posterior femora ; the mouth is also black, and the apex of 
antenns fuscous; the breast is brownish ; the thorax is almost smooth > 
wings ample ; elytra much broader than thorax, with the shoulders well 
marked, apex rounded, rather depressed on disc, very finely and closely 
punctured; apical joints of tarsi and claws fuscous. L, 2-2} mm, 
Male with the last ventral segment of abdomen furnished with a 
central furrow, which is dilated at apex into a triangular fovea. 
By sweeping herbage ; locally common ; Stephens records it as “ extremely abundant 
in several parts of the country in fields, especially where turnips are grown, in June 
and July ;” Weybridge, Mickleham, Darenth Wood, Birch Wood, Horsell, Graves-
