Penn. Bur. PI. Ind., Tech. Bull. No. i, g, 1920; Proc. la. Acad. Sci., iv, 

 212, 1897. 



Vertex produced and acutely angled but a little blunt at tip. 

 Pronotum very strongly convex anteriorly. Straw yellow, ocelli 

 and median impressed line of vertex black. Elytra subhyaline, 

 nervures pale. Female segment with a slightly produced portion 

 at middle, black and trilobate. Male plates rather broad at base, 

 tips narrow, acutely angled and attenuated. Length 3.2 mm. 



A rather common form on Andropogon grasses in high fields 

 or rather dry places. It is more commonly found in western and 

 southern localities, and although not definitely reported from New 

 England it may occur rather sparsely.

D. littoralis Ball. 



Proc. Biol. Soc. Wash., xviii, 120, 1905. 



Vertex produced, obtusely angled, wider than median length, 

 dull yellow, ocelli black and a suggestion of brovv^nish refiexed 

 arcs. Elytra dull greenish, subhyaline, venation pale and con- 

 spicuous ; rather short, in female exceeded by abdomen. Female 

 segment triangularly produced from base, a notch either side just 

 before apex, forming three rather distinct teeth. The processes 

 of an underlying segment visible at each side. Male plates short 

 concaveiy narrowed to pointed tips. Length 3.5-4 mm. 



It has been found only on DisticJilis spicata on sandy areas of 

 the Atlantic Coast, but seems to have a rather wide distribution 

 over such areas during June, July and August.

 D. melsheimerii (Fitch). Amhlyccphalus melsheimerii Fitch. 

 D. vicilinus Grumb. 



I-Iomop. N. Y. St. Cab., 61, 1851. 



A small species with pointed head. Vertex strongly produced 

 and sharply angled, distinctly longer than v/idtli between eyes and 

 longer than pronotum. Female usually rather uniform yellowish, 

 elytra subhyaline, nervures milky white, face with faint arcs. 

 Male brighter yellow, a faint brown arc either side from apex to 

 black ocelli, white nervures of elytra faintly bordered with fuscous 

 throughout. Six or seven pairs of arcs on face. Female last 

 ventral segment about equaling preceding, median half of posterior 

 margin with simple, very shallow, black bordered excavation. 

 Male valve almost semi-circular, considerably longer than preced- 

 ing segment; plates broad at base, only slightly narrowed to 

 broadly rounded upturned tips, appearing from below as almost 

 truncate. Length 2.5-2.75 mm. 



A very common meadow species which is distributed over a large 

 area in the eastern United States. Since its description in 1851 

 this species has been confused with minimus Osborn and Ball, and
