Longitarsus. | PHYTOPHAGA, 345 
By sweeping herbage; often found in haystack refuse, moss, &c.; generally 
distributed and common throughout the greater part of the kingdom. 
L. atriceps, Kuts. (melanocephalus, De G. et Gyll., sec. Thoms., &c.). 
Smaller on the average than the preceding species, which it much 
resembles, with the elytra more oblong, and with the first joint of the 
tarsi and the apical spur of the posterior tibie shorter; the elytra also 
are rounded together at apex, and have the sutural angles almost right 
angles, and the second joint of the antenne is rather longer in proportion; 
in colour the species much resemble one another, except that in L. atriceps 
the head and posterior tibiz are, as a rule, more decidedly darker. L. 
13-12 mm. 
By sweeping herbage; rare; Darenth Wood; Shirley ; Wootton, near Dorking ; 
Devon (Wollaston) ; Chat Moss (Reston). 
L. distinguendus, Rye. Oblong, head and thorax shining, elytra 
very finely alutaceous and therefore a little duller, ferruginous testaceous, 
or testaceous, with the under-side darker, and the greater part of the 
posterior femora, the apical joint of the tarsi, and the six or seven apical 
joints of the antenne more or less, pitchy black ; antenne rather stout, 
almost as long as the body ; thorax closely and finely, and often obsoletely, 
punctured ; wings absent ; elytra rather long, with shoulders obliquely 
rounded, but slightly prominent, suture narrowly darker, usually 
rufescent, sutural angles somewhat obtuse, punctuation rather deep, 
arranged in rows towards base. L. 2-23 mm. 
Male with the last ventral segment furnished with a smooth longi- 
tudinal impression in the centre, and the posterior margin incrassate ; 
the basal joint, moreover, of the anterior tarsi is triangularly produced 
and dilated internally towards apex. 
On Teucrium scorodonia and Scrophularia nodosa ; very local and usually rare; 
Mickleham (Rye) ; Chatham (Walker) ; Box Hill, in profusion in September and 
October (Champion). 
Mr. Rye, in his description, compares this species with Z. atricillus, 
from which it may be easily known by not having a dark brassy head 
and thorax, and by the fact that the punctures on the elytra are more or 
less disposed in rows ; the posterior tarsi also are longer and the antennze 
are stouter, and the general colour is lighter, the suture in 7. atricillus 
being fuscous and not rufescent. 
L. suturalis, Marsh. (nzgricollis, Foudr.). Ovate, not very convex, 
with the head, thorax, suture of elytra, chief part of posterior femora, 
apical joint of tarsi, antenne, except base, and under-side, black, and 
the elytra, except suture, pale testaceous ; head large, antenne long and 
slender; thorax with sides rounded, distinctly punctured; scutellum 
pitchy, smooth ; wings ample; elytra with shoulders projecting and not 
obliquely rounded, rather long, rounded at apex, with the sutural angle 
obtuse, somewhat strongly and very distinctly punctured; legs, except 
posterior femora, testaceous. L. 2-21 mm,
