 tral surface of abdomen dull red; front margin of pronotum, clavus ex- 

 cept margins, hind margin of corium, very narrow edge of membrane, 

 bucculae and pleura in great part, pale yellow; elytra rather thickly 

 covered with small pale oval whitish scales. Third and fourth joints of

Lake, Marion, Martin, Dubois, Crawford, Perry and Posey 

 counties, Ind., May 9 — July 1. Borden Springs, Ala., Aug. 15. 

 Ormond and Dunedin, Fla., March 17 — April 7 (W. S. B.). Ag- 

 ricultural College, Miss. (Weed). In Indiana it occurs on herb- 

 age, usually in low moist places. About Ormond, Fla., it was 

 common the last of March on flowers of Senecio and other plants. 

 At Dunedin it is scarce in spring on flowers of a dwarf papaw 

 and low huckleberry. Charlotte Harbor and Atlantic Beach 

 are the only other recorded stations from Florida. The general 

 range of bicrucis is southern, extending from New York west 

 to northern Illinois, Kansas and Colorado, and south and south- 

 west to Texas, California, Mexico, Venezuela and Brazil. In 

 Illinois Hart found it common in August on the flowers of the 

 pale Indian Plantain, Mesadenia atriplicifolia L. In both that 

 State and Indiana it is more common in sandy localities than 

 elsewhere.
