D. minimus Osborn and Ball. Deltocephalus melsheimerii Van 

 Duzee. 



Proc. la. Acad. Sci., iv, 211, 1897. 



Very small, vertex produced, longer than width between eyes, 

 bluntly angled at tip. Pronotum very strongly convex anteriorly, 

 lateral margin almost obsolete. Vertex yellowish green, ocelli 

 black, margin slightly infuscated. Elytra greenish, subhyaline, 

 venation somewhat obscured. Female segment slightly produced, 

 medially notched, with a black spot either side. Male plates long, 

 gradually narrowed to acute tips. A black spot near middle of 

 either plate. Length 2.75-3 mm - 



This species resembles closely melsheimerii (Fitch), and they are 

 frequently confused in collections. Common on grasses in 

 pastures and uncultivated areas. Old pastures are ideal feeding 

 places in July and August.

 cephalus sabulicola Curtis. Deltocephalus affinis Gillette and 

 Baker. Deltocephalus affinis Van Duzee. (PL iii, 5.) 



Hemip. Col., 84, 1895. 



Robust, vertex wider than long, obtusely angled, yellow or 

 fuscous, often with darker markings. Pronotum with very short 

 lateral margins and marked with darker longitudinal bands. 

 Elytra dull green, venation paler and conspicuous. Face infus- 

 cated, with numerous pale arcs. Female segment concavely 

 rounded. Male plates very short and rounded, scarcely exceeding 

 convex valve. Length 3.5-4 mm. 



Quite variable in coloration, often pale or heavily marked. 



A very common and widely distributed form throughout the 

 summer feeding in pastures and meadows on field and swamp 

 grasses. Common in New England. 



There has been some confusion regarding the synonymy of 

 this species but a careful study of European material and material 

 from Prof. Gillette show them to be the same species which has 

 been described at least twice in Europe and once in this country.
