Type of the Genus, Lygseus chiragra Fab. 



Rhyparochromus Hahn., Curt. — Pachymerus LePel. — Aphanus 

 LaPorte. — Lygseus Fab., Fall. — Cimex Linn. 

 Antenna inserted on each side of the head before the eyes, as 

 long as the head and thorax, filiform, hairy and 4-jointed, basal 

 joint rather short, oblong, 3 following long, nearly of equal 

 length, 2nd and 3rd clavate, the latter sometimes the shortest, 

 4th a little the longest and fusiform (4). 



Labrum as long as the basal joint of the labium, strap-shaped, 

 but slightly attenuated (3). 

 Mandibles and Maxillce setiform. 



Labium as long as the antennse, stout, inflected and 4-jointed, 

 first 3 joints nearly of equal length, 2nd jsrobably a little the 

 longest, 4th a little the shortest, the apex conical (2). 

 Head rather small and trigonate : eyes small, prominent, lateral and 

 rather oval : ocelli 2, minute and placed close to the base of the 

 head (1, the head in profile). Thorax long and broad, subcampanu- 

 late : scutel large trigonate and acute. Abdomen elongate-ovate. 

 Elytra generally covering the abdomen, horny, with 2 or 3 indistinct 

 nervures towards the base, and 5 imperfect longitudinal ones on the 

 apical membrane (9). Wings short and broad, with several furcate

The following British species vary in the shape of the thorax, 

 some being oblong, others a little transverse, yet it would be 

 difficult to form them into sections. 



1. Echii Fab. — Panz. 72. 22. — carbonarius Rossi. — aterrimus 



Wolff: 19. 192. — Genus Polyacanthus LaPorte. 



2. micropterus Curt. Narrow, black and sliining, thorax campanulate, 



convex, excepting the base which is flat and testaceous as well as the 

 elytra, which are very short, with brown rows of punctures and edged
