372 FAMILY XI. — LYG;£IDj£. 



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



"Shorter and narrower than typical leucopterus. Antennae with ter- 

 minal segment relatively shorter. Pronotum deep velvety black, an- 

 teriorly prominently silver-gray, the villosity shorter and sparser. Hemi- 

 elytra appearing more whitish, the veins not stramineous but concolorous 

 with the whitish membranous areas; commissural margin of the clavus, 

 apical margin of corium, median vein apically and apical spot strongly 

 piceous. Femora frequently castaneous." {Barber). 



Dunedin and R. P. Park, Fla., Dec. 3 — April 9. Frequent at 

 Dunedin in bunches of grass-roots along the bay front ; also be- 

 neath boards in sandy localities one-half mile inland. While Bar- 

 ber states that "this variety inhabits the coastal strip of Flor- 

 ida and that there it is always brachypterous," both long- and 

 short-winged forms were among those taken on the beach at 

 Dunedin, the latter, however, predominating. In Porto Rico he 

 found both macropterous and brachypterous forms. It is but 

 a color variety of leucopterus which is found in sandy regions. 

 The specimens of the typical form occurring in sandy places in 

 Indiana have the front half of pronotum more silvery-gray than 

 those from non-sandy localities, and Say, in his original de- 

 scription of his Virginia type, says "thorax tinged with ciner- 

 ous before." 



Subfamily IV. GEOCORINiE Stal, 1862a, 212. 



Small oblong-oval species having the head broader than long ; 

 eyes very prominent, projecting backward and overlapping the 

 front of pronotum (fig. 80) ; antennae shorter than head and 

 pronotum united, first joint not exceeding apex of head, third 

 and fourth usually subequal, second slightly longer ; beak reach- 

 ing middle coxse; pronotum transverse, sparsely punctate, not 

 carinate or separated into distinct lobes ; scutellum elongate- 

 triangular, apex acute ; clavus long, very narrow, the com- 

 missure absent or very short ; elytra in macropterous forms 

 covering the abdomen, the membrane large and extending be- 

 yond its tip, in brachypterous ones very small, not surpassing 

 fifth dorsal. Females with sides of fifth and sixth ventrals 

 narrowed, slightly overlapping, reaching the median line of 

 abdomen. Other characters as in subfamily key. The sub- 

 family comprises two genera, both represented in the eastern 

 states.
