TRIBE I. — GALEATINI. 469 



nected by a curved fuscous stripe along each sutural area, both bars and 

 stripes formed only by the darkened nervures and slightly darker cells; 

 nervures of remainder of upper surface straw-yellow, the cells clear hya- 

 line. Antennas filiform throughout, finely and sparsely pilose, first 

 joint three times the length of second, third longer than the others 

 united; fourth slightly longer than first and second united. Structural 

 characters as under generic heading. Length, 3.1 — 3.5 mm. (PL IV, 

 fig. 8). 



Newark and Riverton, N. J., September (Weiss). Recorded 

 in this country only from New Jersey, Pennsylvania and 

 Washington, D. C. Known as the "azalea lace-bug," and prob- 

 ably introduced from Japan on evergreen azaleas. The nymphs 

 and adults feed on the under surface of the leaves, abstracting 

 the sap and causing the upper surface to become whitened." 6 



IV. Leptobyrsa Stal, 1873, 119. 



Small oval species having the antennae very slender, basal 

 joint exceeding apex of head, twice as long as second, third 

 more than twice as long as the others united; head with five 

 rather short spines ; hood small, triangular, compressed, oc- 

 cupying only the anterior third of pronotum, but extending 

 completely over the head; hind portion of pronotum abbrevi- 

 ated, its tip obtuse; carina? all entire, the median one slightly 

 higher than hood ; elytra very broad, nearly twice as long as 

 abdomen, narrowed at base, their tips broadly rounded. Van 

 Duzee (1917, 216) has, in my opinion, erroneously made this 

 genus a synonym of Stephanitis. Two species are known from 

 the eastern states. 



KEY TO EASTERN SPECIES OF LEPTOBYRSA. 



a. Larger, length 3.6 mm. ; elytra with a vague brownish transverse 



band in front of middle. 430. rhododendri. 



aa. Smaller, not over 3.2 mm.; elytra with only three cross nervures 



dark. 431. blatchleyi. 



430 (653). Leptobyrsa rhododendri (Horvath), 1905, 567. 



Broadly oval, strongly dilated behind. Head, under surface and 

 disk of pronotum black, shining; nervures of upper surface straw-yel- 

 low, the cells hyaline; an oblique spot on median pronotal carina and 

 some of the nervures at basal third of elytra fuscous-brown, the latter 

 forming a vague brownish cross-bar; antenna?, bucculae and legs pale 

 dull yellow, the tarsal claws and apical half of fourth antennal darker. 

 Paranota semi-elliptical, strongly reflexed. Elytra widening from the 

 base, their areolae large. Length, 3.5 — 3.8 mm. (Fig. 105).
