go Hlemiptera-Heteroptera. 
tured near its centre, more closely in front, and with very 
large punctures near the base; scutellum dull, punctured 
and with short bristles; elytra with the corium and clavus 
clothed with short bristly upright hairs, punctured with 
black in lines; abdomen beneath pilose; legs with erect 
bristles, anterior femora incrassated, simple. 
L. 2 mm. 
Very rare, Sandwich on the sandhills; the only recent 
capture of this species was made by Mr. A. Piffard, in 
June, 1890. The Rev. T. A. Marshall writes to me that 
he found it at Swanage, but did not capture any. 
PLINTHISUS, Ficb. 
Flat, glabrous, shining. Head much narrower than 
the pronotum, antenniferous tubercles very small, ocelli 
distinct, eyes touching or nearly touching the pronotum, the 
anterior angles of which slightly embrace them ; pronotum 
with the anterior margin deeply emarginate, sides rounded 
near the anterior angles then nearly straight, margins 
finely carinated, base slightly sinuate, disc nearly flat ; 
elytra in the developed form with the membrane nearly 
reaching to the apex of the abdomen, in the undeveloped 
form shortened, exposing one or more abdominal segments ; 
legs with the anterior femora incrassated, with two small 
sharp spines beneath. 
There are over twenty species of this genus in the 
Palearctic fauna, but we have only one as yet in this 
country. P. pusillus, however, is quite likely to occur 
here ; the others have mostly a southern distribution. 
P. brevipennis, Latr. (macr. bidentulus, H. Schff:).— 
Pitchy black, or more or less brown, shining, glabrous. 
Head finely and very shallowly punctured, antennze 
piceous ; pronotum slightly widened posteriorly (macr.), 
or subquadrate (brach.), deeply punctured posteriorly, 
superficially so on the disc ; scutellum punctured ; elytra
