jean. The best distinguishing character is the more fusiform 
shape of the terminal joints of the palpi, and there are slight 
differences in the labrum, mandibles, and antennae, which will 
present themselves on a comparison of our plates. 
The species called Argutor Anthracinus by Stephens, and 
incorporated with that genus by him, appears to be the Oma- 
seus minor of Dejean ; I have therefore omitted it here, and de- 
scribed it with all the other species in the 2nd edition of this 
work under the genus Omaseus. 
* Elytra with 2 short stria: next the scutellum . 
1. pullus Gyll. — diligens Sturm. Deut. Faun. tab. 1 1 7 .f. A. var .? 
Found near London and in Devonshire.

66 In a gravel pit near Hertford.” Step. 
The short stria: wanting . 
5. longicollis Drift . ? — Curt . B. E . pi. 666 $. — negligens Meg. 
This I take to be the true longicollis , but I have specimens 
agreeing better with Sturm’s fig. D, pi. 116, and measuring 3 
lines, w 7 hich also want the 3 punctures between the 2nd and 
3rd striae. Four specimens were taken by R. H. Spence, Esq., 
in October, under rejectamenta on the banks of the river 
Itching.

and gravel-pits; Belton Bog in moss, Mr. Paget.

Piceous-black; trophi, base of antennae and legs ferruginous: 
thorax orbicular nearly as broad as the elytra, concave be- 
fore, truncated at the base, the angles not acute, lateral mar- 
gins rufous, except anteriorly, base thickly punctured, with 
an impressed line on each side and a channel down the mid- 
dle : elytra deeply striated, with 3 punctures between the 
2nd and 3rd striae. 
I have only a male, which I took in Norfolk : it most re- 
sembles A. vernalis.
