154 CONNECTICUT GEOL. AND NAT. HIST. SURVEY. [Bull. 



Perhaps this feeds on herbaceous vegetation, as it has been taken 

 in general sweeping in open areas. 



New Haven, 4 July, 1920 (B. H. W.) ; East Hartford, 16 Sept., 1920 

 (B. H. W.). 

 E. coccinea (Fitch). Empoa coccinea Fitch. 



Rather small, vertex blunt, strongly rounded. Vertex, prono- 

 tum, scutellum and face to apex of clypeus, a bright, deep red. 

 Elytra smoky subhyaline, costal vein greenish. Very conspicu- 

 ously marked. Length 3 mm. 



Recorded from pine by Dr. Fitch; although no other collector 

 has designated where it was taken the species is more often found 

 in areas where pines are abundant, and this may prove to be its 

 food plant. 

 E. alboneura Gillette. 



Proc. U. S. Nat. Mus., xx, 743, 1898. 



Small robust, vertex somewhat produced and pointed in front. 

 Pale green, a longitudinal pale line across vertex, pronotum, and 

 scutellum. Elytra with tips smoky, and all the nervures pale. 

 Length 3 mm. 



From collecting records it would seem that this little species is 

 able to feed both on shrub and herbaceous plants. 

 E. mali (LeBaron). Tettigonia mali LeBaron. Empoa alb opicta 

 Forbes. Apple Leaf-hopper. 



Prairie Farmer, xiii, 330, 1853. 



Vertex produced, obtusely angled. Greenish to yellow with a 

 row of six to eight white spots on anterior margin of pronotum. 

 Length 3.25 mm. 



A cosmopolitan feeder being a pest of apple, alfalfa, grain and 

 truck crops, and attributed with the carrying of fungus diseases. 

 One of our most important pests. 



New Haven, 16, 31 Oct., 1903 (H. L. V.) ; Cornwall, 18 July, 1921 

 (B. H. W.) ; Ellington, 8 Aug., 1922 (B. H. W.), on apple; Hamden, 14 

 July, 1921 (P. G.), on potato. 



E. flavescens (Fabricius). Cicada flavescens Fabricius. (Fig.

Ent. Syst, iv, 46, 1794. 



Resembling mali in size, form and color, but with three white 

 spots or none on anterior margin of pronotum. Color bright green 

 to yellow. Length 3.25 mm. 



It occupies about the same economic position as the preceding, 

 and is found to feed on the same types of vegetation.
