This curious little insect not agreeing with any genus de- 
scribed, I have been under the necessity of giving it a name. 
It is evidently related to Proteinus of Latreille in form, from 
which however it may be distinguished by its shorter elytra, 
which leave seven segments of the abdomen uncovered, as 
well as by its very differently formed palpi. 
I have adopted the specific name, which I understand has 
been given to it by Mr. Kirby ; and there is reason to believe 
that it is the new species of Evaesthetus mentioned in the 66 In- 
troduction to Entomology,” (vol. 4-. p. 503.) as having been cap- 
tured in a chalk-pit near Barham, Suffolk. For the specimens 
in my own cabinet I am indebted to Francis Walker, Esq., 
who took them out of moss, which was collected in the months 
of December and January, at Southgate, Middlesex. 
The plant is Thesium Imophyllum (Bastard Toad-Flax), for 
a specimen of which I am indebted to the Rev. Professor 
Henslow, who gathered it the middle of June in the Devil’s 
ditch, Cambridgeshire.
