Longitarsus. | PHYTOPHAGA, 853 
L. gracilis, Kuts. Oblong ovate, rather depressed, shining, of a 
whitish-testaceous colour, with the head, breast and abdomen pale 
ferruginous and the mouth pitchy; antenne rather long, dark with the 
base light; thorax very finely punctured, or almost smooth ; wings 
present ; elyira ovate, semi-transparent, with the shoulders moderately 
transparent, and the apices separately rounded, very finely and con- 
fusedly punctured, the punctures being sometimes almost obsolete ; legs 
testaceous, with posterior femora sometimes slightly darker, posterior 
tibiz with a short spur at apex, last joints of tarsi and the claws pitchy. 
L. 13-12 mm. 
Male with the fifth ventral segment of abdomen furnished with a 
thin longitudinal line, and bisinuate at apex. 
On Senecio jacobea; locally common; Mickleham, Caterham, Darenth Wood, 
Bearsted near Maidstone, Bushey, Wootton, Reigate, Whitstable, Southend ; Ulting, 
Essex ; Wicken Fen; Hastings; Lee Valley, Devon; Chat Moss; Bowdon, Man- 
chester ; Northumberland district, Sweethope (Power); Ireland, near Waterford 
(Power). 
This species much resembles L, ochrolewcus, but may be distinguished 
by the absence of the black colouring at the apex of the posterior tibie ; 
the thorax also is broader than in that species. 
A species was described by Allard, and named by him Thyamis Powerit 
as closely resembling 7. gracilis, but differing from that species in 
having the vertex, scutellum, sutural margins of the elytra, breast and 
abdomen brown, the joints of the antennz longer, the seven apical joints 
being darker, and the punctuation of the thorax closer and more distinct, 
and of the elytra more evident; four specimens were taken by Dr. 
Power at Mickleham ; Rye referred the species to 7’. gracilis, and says 
that neither of the two specimens which he had seen possessed all the 
characters given by M. Allard, which at most are not very pronounced ; 
in the European catalogue the species is given as synonymous with 
T. piciceps, Steph. Rye is, however, probably right in referring Dr. 
Power’s specimens to 7’. gracilis. 
L. levis; Duft. Oblong ovate, almost obovate, convex, shining, of 
a pale testaceous colour, with the labrum fuscous black, under-side and 
apex of posterior femora light ferruginous; antennze very long, nearly as 
long as the body, testaceous, with the last two or three joints darker ; 
thorax convex, nearly smooth, or with a few very fine scattered punc- 
tures; wings absent ; elytra with the shoulders rounded and effaced, 
almost impunctate or very finely punctured, the punctuation being more 
visible at base; under-side obsoletely punctured ; posterior tibiw with a 
small very short spine at apex. L. 13-2 mm. 
Male with the fifth ventral segment of the abdomen furnished in the 
centre with a very smooth and shining blackish line. 
On Chrysanthemum, Artemisia, &c.; locally common and very widely distributed ; 
Dulwich, Weybridge, Mickleham, Chatham, Sheerness, Whitstable; Dagenham, 
Essex; Wicken Fen; Deal; Dover; Hastings; St. Leonards Forest; Eastbourne ;
