British Hemiptera-Heteroptera. 159 
2. claviculus, Fall. Fig. Dougl. & Scott, Brit. Hem. 
pl. vi. fig. 8. 
Differs from preceding in being smaller and having the 
elytra of a less oval shape. The scutellum also is less 
strongly carinated, and the apical margin of the corium is 
brown and much shorter. 
Length 15—1 line. 
Common by sweeping, &c. 
3. melanocephalus, Fieb. 
Nearest allied to claviculus; differs in its darker colour, 
especially the darker colour of the head and front of thorax, 
in having the keel of the thorax concolorous and in not 
having any keel on the scutellum, and also in the punc- 
tuation of the corium, which is irregular all over; whereas, 
in claviculus, along the claval suture there are two sub- 
parallel rows of punctures with an impunctate space 
between them, the rest being closely and irregularly 
punctured. 
Length 1? line. 
Not uncommon in damp places, Chobham and Reigate; 
probably generally distributed, but overlooked.
