Lafayette, Ind., May 15 ; taken from hollyhock. Known as 

 the "hollyhock bug." Recorded only from Michigan. Hussey 

 found it common at Ann Arbor, June to late September ; all 

 stages occuring on the upper side of the leaves of hollyhock 

 and doing serious damage thereto. Originally described** by 

 A. J. Cook as Orthotylus delicatus Uhler (Ms.), which name was 

 preoccupied.

 blackish ones; head and apical third of pronotum fading to dull yellow; 

 membrane uniformly pale brownish-hyaline, iridescent, veins yellowish to 

 dusky; legs yellowish-green, third joint and claws of tarsi piceous. Joint 

 1 of antenna? greenish, three-fourths as long as width of vertex; 2 yel- 

 lowish, brownish toward apex, three and a half times as long as 1; 3 

 and 4 dark brown, 3 three-fourths as long as 2, 4 one-third the length of 3,

Herefordshire, England, Aug. 13 (British Mus. Coll.). A 

 European species recorded in this country only from Massachu- 

 setts. Somewhat larger and stouter than flavosparsus and with-

 low; above sparsely clothed with short inclined blackish hairs; legs and 

 antennae concolorous; membrane pale, the veins only greenish. Joint 1 of 

 antenna? as long as width of vertex, 2 three and a half times as long as

 (Fig. 184). 



Marion and Vigo counties, Ind., June 3 — July 15 ; frequent 

 on leaves of the host plant, the thorn or honey-locust. De- 

 scribed from Indiana. The known range extends from Quebec 

 and New England west to Indiana. Recorded also from Califor- 

 nia. Specimens are at hand, identified for me by Uhler as 0. 

 alternatus Uhler (Ms.). It is more robust than flavosparsus, from 

 which it may be separated by the concolorous cells of mem- 

 brane and lack of patches of pale pubescence; from uniformis
