At once distinguished by its superior size from Pt. exclamationis, 

 and by the greater length of the vertex both from that and from Pt. 

 spumarius. It does not vary much in colour, and always shows traces 

 of the characteristic black dash upon the hemelytra It is very abun- 

 dant upon plants in hedges, gardens, and woods, but perhaps less ob- 

 trusively common than Pt. spumarius.

 bus fusco-testaceus. Frons transversim nigro-striata. Hemelytrorum 

 costa ad medium usque, cum macula magna laterali (nonnunquam gemi- 

 nata,) albo-pellucida : margo apicalis anguste niger, nigredine in maeu-

The smallest British species, nearly invariable in its markings, and 

 somewhat local. It seems to prefer fine dry grasses in elevated situa- 

 tions. My specimens are from Swithland Slate Quarries, Leicester sliii-e ; 

 and Wimbledon Common. 



3. — Ptyelm spumarius, Lin. 



De coloribus, ultra modum variantibus, nihil dicendum. Tantum 

 ex alarum nervis, verticis femorumque posticorum brevitate, discrimen 

 petendum. In alse apice nervus longitudinalis tertius (a margine ex- 

 terno) bifurcatus in costam excurrit, qui in speciebus 1 et 2 simplex est 

 atque indivisus. Corpus totum breviter sericeum. Subtilissime punc- 

 tulatum. ^ $ . Long. 2|-3^ ; alar. exp. 6^ lin. 



The following eleven Fabrician species represent the leading va- 

 rieties of this insect. The whole of the copious synonymy may be seen 

 in Flor, E.L. 2, p. 126-130, and in the list of Brit. Mus. Homopt. by 

 Mr. Walker.
