ham, but it appears to me that they ought rather to be referred to 
L. luridus. 
L. pulex, Schrank. (obJiteratus, Rosh.). Oblong-ovate, deep black 
or pitchy black; antenne longer than half the body, pale testaceous 
with the last joints darker; thorax very closely punctured, somewhat 
shagreened, often with a slight bronze reflection ; scutellum transverse, 
rounded ; wings absent or rudimentary ; elytra convex, obtusely rounded 
at apex, rather distinctly and substriately punctured; legs testaceous- 
yellow, posterior femora pitchy black; under-side pitchy, smooth, and 
scarcely punctured. L. 1j-1} mm. 
Chalky places; on Yeucrium scorodonia (Wood-sage), Thymus serpyllum, &c.; 
very local, but common where it occurs; Mickleham, Reigate, Caterham, Chatham, 
Sevenoaks, Bearsted ; Dover; Folkestone; Swansea; Ireland, Armagh. 
L. anchuse, Payk. Larger than the preceding, from which it may 
also be known by its much stouter antenne and darker legs, and by the 
fact that the elytra do not completely cover the abdomen; antennz 
pitchy with base ferruginous ; thorax closely and very finely punctured ; 
scutellum rounded, smooth; wings absent, at all events in the males; 
elytra obliquely rounded at shoulders and dilated just behind middle, 
very obtuse and separately rounded at apex, dehiscent at sutural angle, 
moderately strongly punctured, not covering pygidium ; legs testaceous 
or ferruginous with the posterior femora black, and the anterior and 
intermediate femora infuscate except at apex. L. 1$-2 mm. 
Chalky and sandy places; on Eehium vulgare, Cynoglossum, Anchusa, &c.; local, 
but common where it occurs ; Mickleham, Darenth Wood, Hammersmith, Claygate, 
Headley Lane, Bearsted, Maidstone ; Bognor; Portsdown, near Portsmouth, abundant 
in June (Moncreaff); Bristol; Northumberland and Durham district, Sweethope 
and Wallington (Power). 
L. ater, F. (parvulus, Payk.). Ovate, pitchy-brown, or black, with 
a slight bronze reflection, under-side black; antenne longer than half 
the body, pitchy with base testaceous ; thorax very finely punctured ; 
scutellum small, triangular ; wings present ; elytra rather broad, very 
finely punctured, a point that will separate the species from L pulex, 
which it much resembles ; legs long, testaceous, posterior femora pitchy, 
anterior and intermediate femora often infuscate at base; occasionally 
the bronze colour is very marked. L. 1-1} mm. 
On low plants, and also, according to Allard, abundantly on the common horn- 
beam (Carpinus betulus); very local; London district, rare, Chatham, Dulwich ; 
Whitstable; Birchington; Deal; Ditchingham, near Bungay, Suffolk, abundant 
(Power) ; Ashwicken and Wicken Fen; Markfield, Leicester ; Portsmouth district ; 
Seaton Down, Devon; Ireland, Rathkurby, near Waterford (Power); Belfast 
(Haliday) and Armagh (Johnson). 
L. absinthii, Kuts. Closely allied to L. anchuse, but distinguished 
by its colour which is slightly bluish, and by the more strongly pune- 
tured elytra which are less rounded at apex, and have two obseurely 
testaceous spots on each one at apex and another at shoulder, which are
