 spots on C prothorax and A mesothorax, and brownish claw. Abdo-

/?em«rylr?.— Material described was collected May 26, 1913, at East 

 Falls Church, Virginia, by William Middleton and recorded under 

 Hopk. U. S. number 11362, June 26, 1913. The species is also re- 

 corded from Great Falls and Dixie Landing, Virginia. 



The larvae feed on the leaves from the under side of leaves and 

 are not especially active. On May 31, 1913, all larvae were in ground. 

 May 21, 1914, four adults emerged. 



ACORDULECERA HICORIAE Rohwer. 



Zarya.— Stage VI (?). 



Structure. — Head: Similar to A. foveata. Thorax: Similar to A. 

 foveata., but preepipleurite rather distinct from B in the prothorax 

 and the alar area in the mesothorax and metathorax. Abdomen: 

 similar to A. foveata but uropods on urites 6 and 7 more distinctly 

 smaller than those on urites 2-5. 



Color. — Head: Brownish black (occasionally with some white); 

 eye disks black; mandibles, labrum, and joints and chitin of ven- 

 tral mouth parts, brownish. Body: Pale yellowish green, nearly 

 white, marked as follows: Legs with joints brown; prothorax with 

 neck plates brown, C with large, subdorsal, brown spot, B with 

 large, alar, brown spot, and preepipleurite, prehypopleurite and post- 

 hypopleurite brownish; mesothorax and metathorax A with sub- 

 dorsal and supraalar brown spots. B with spot extending from sub- 

 dorsal to supraalar regions, C similar but with the spots tending to 

 divide into a subdorsal, laterodorsal, and supraalar spot. Abdomen : 

 The tergum with A. B, and C similar on urites 1 to 9 (B and C spots 

 confluent forming a large blotch on urites 6 to 9, inclusive) ; urite 10 

 with epiproct brownish; alar area brown on urites 1 to 8; the 

 pleurum with preepipleurite brownish on urites 1 to 9 ; postepipleu- 

 rite brownish on urites 1 to 8 (crescent-shaped areas on 2 to 4 and 8 

 white), with small spots on postepipleurite of urite 9; and urit« 10 

 with entire pleurum pale. Larvae vary somewhat, the paler forms 

 with the abdomen mostly devoid of brown. (These are usually 

 younger larvae.) 



Cocoon. — Similar to that of A. foveata. 

 Host. — Hicoria., species.
