SUBFAMILY III. — BUSSING. 371 



young wheat and corn, those of the second in August and Sep- 

 tember, the adults of this brood surviving the winter. Full ac- 

 counts of the life history and remedies are given in various 

 publications of the U. S. Bureau of Entomology, notably those 

 of F. M. Webster, issued as Bulletin 69 and Circular 113. 



The known range of typical B. leucopterus extends from Que- 

 bec and New England west to Vancouver, Dakota and Colo- 

 rado and south and southwest to Florida, Texas and Mexico. 

 It has also been recorded from a few isolated stations in Ari- 

 zona, California and Washington. East of the Alleghenies it 

 is single brooded and is much less common than in the Central 

 West, seldom occurring in sufficient numbers to do much dam- 

 age. In Florida I have taken the typical form at Lakeland, 

 Moore Haven and Dunedin, though the majority of those found 

 about Dunedin and other seacoast localities belong to var. in- 

 sularis Barb. The insect has many natural enemies, chief 

 among which are the quail, several species of ground beetles 

 and Heteroptera and the chinch-bug fungus, Sporotrichium glo- 

 biliferum Speg., this fungus being especially beneficial in wet 

 seasons. 



313a ( — ). Blissus leucopterus arenarius Barber, 1918a, 38. 



"Longer and narrower than leucopterus Say, the abdomen being 

 distinctly longer than head and thorax united. Villosity of pronotum 

 shorter, less dense, and grayish. Hemielytra with membranous area more 

 sordid white, the veins limiting the clavus and those of posterior margin 

 and other parts of corium for the most part stramineous or faintly tinged 

 with brown; legs oehraceous." {Barber). Other characters as in key. 

 Length, 3.7 mm. 



Rockaway Beach, Long Island, N. Y., May 25 (Barber) . The 

 types were "collected on a species of sand grass growing back 

 of the sand dunes along the ocean beach" at Sandy Hook, N. 

 J., and Coney and Long Islands, N. Y. 



313b (497). Blissus leucopterus hirtus Montandon, 1893a, 405. 



More robust than typical leucopterus with longer, denser and more 

 erect yellowish hairs on pronotum and sides of abdomen; femora often 

 dark brown. Length, 4 — 4.3 mm. 



Cascade Lake, Adirondack Mountains, Aug. 18 (Barber). 

 Occurs mainly in the higher regions of Canada and the eastern 

 states. The unique type was from Hazelton, Pa., and, accord- 

 ing to Barber (1918a, 38), "was unusual in lacking the piceous 

 spot at the apex of the corium."
