This is one of the most abundant species, and either of its forms 

 may readily be taken in grass fields, especially when newly mown. It 

 is somewhat variable, and the typical black stria in the angle of the 

 clavus is frequently indistinct. The medial frontal carina is forked 

 very close to the vertex, forming a small triangle. This species is likely 

 to be confounded with D. neglectiis and pellucidus : the former how- 

 ever differs in having the frontal carinje concolorous with the face, and 

 the sides of the scutellum and pronotum occupied by a broad bi'own 

 stripe ; the latter is known by the distinctly impressed and close 

 punctures of the nervures of the bemelytra : while both are sufficiently 

 separated from striatellus by the structural characters indicated in the 

 synopsis.

Although I have only a single specimen (taken in Darenth Wood), 

 its agreement with the descriptions above referred to is so exact, as to 

 leave no room for doubt as to the species. The medial frontal carina 

 is forked somewhat lower down than in the preceding, forming a more 

 elongate triangle, whose apex is nearly upon a level with the inferior 

 margin of the eyes. The segments of the abdomen (and especially the 

 genital segment,) are testaceous brown in the middle of their hinder 

 edges.
