No. 34.] HEMIPTERA OF CONNECTICUT: CICADELLIDAE. 9 1 



23. Head narrower than pronotum which is somewhat angularly pro- 



duced between the eyes. (Fig. 10, 11.) Balclutha, p. 145 



Head as wide as or wider than pronotum, anterior margin of which 

 is well rounded and but slightly produced. (Fig. 10, 12 and 13.) 24 



24, Head slightly produced, usually with definite color markings. (Fig. 



10, 13.) Cicadula, p. 142 



Head very blunt, not produced, parallel margined, without definite 

 color markings. (Fig. 10, 12.) Eugnathodus, p. 146 



Dorydiella Baker. 



Head broader and longer than pronotum, anterior margin 

 roundingly angulate, foliaceous and upturned, ocelli on margin 

 close to eyes. Elytra long, with apices acutely angled. Four 

 apical cells and two anteapical. Clavus with two longitudinal 

 veins. Only one species is known to belong to this genus. 

 D. floridana Baker. 



Can. Ent, xxix, 159, 1897. 



Large, yellowish with brown markings. Vertex long, broad and 

 flat with margin foliaceous, upturned in front. Elytra long, 

 apices acutely angled. Face somewhat irrorate, vertex with five 

 dark spots on anterior edge. Pronotum longitudinally striate. 

 Elytra with ramose pigment lines mostly longitudinal, apex with 

 brown spot. Length 8 mm. 



Although rather difficult to collect, it occurs in abundance during 

 late August and early September at the margins of lagoons on the 

 young Scleria-Eleocharis growth which follows the receding water- 

 line as evaporation takes place. 



In general appearance and color markings this species resembles 

 quite closely species of Phlepsius and the pointed elytra would 

 suggest a relationship to Acinopterus. The head character, how- 

 ever, is more closely allied to the Dorycephalus type and this is 

 more pronounced in the nymphs than in the adults. It is, there- 

 fore, given this relative position, since the nymphal characters are 

 most important. 



Hecalus Stal. 



Glossocratus Fieber. 



Vertex longer than basal width and flattened, sharp and folia- 

 ceous at margin. Pronotum very short and broad. Clavus of

 stripes extending across vertex and pronotum and central two
