Allotypic 9 . Data the same as the type. 



Description of Allotype. — Slightly larger than male. Pronotum, 

 mesonotum and metanotum noticeably narrower than in antillarum, 

 bringing into prominence the depressed ovate abdomen. Tegmina 

 absent. Subgenital plate semi-ovate, broadly obtuse-angulate emar- 

 ginate at apex. Ovipositor as in antillarum. 



In addition to the type and allotype, the following specimens may 

 be considered paratypic: Isle of Hope, Ga. ; Sept. 3, 1911; (R. andH.); 

 1 cf n. Sandfly, Ga.; Sept, 3, 1911; (R. and H.); 1 9 .

The measurements would indicate that this species is smaller than 

 specimens of antillarum from the same place over the greater portion 

 of its range, but as it decreases in size southward much less rapidly 

 than that species, the two species are very nearly of the same size 

 in southern Florida, though their proportions markedly differ. 



Color Notes. — There is scarcely any difference in ground coloration 

 between antillarum and the present species, except that, in the series 

 of the latter species before us, the maxillary palpi are never darkly 

 suffused, though of a richer brown than the surrounding facial parts, 

 and all have the dorsal surface of the abdomen wholly black. The 

 insects are thickly covered with nearly transparent scales, so that in 

 the field they frequently appear to have the black abdomen ringed 

 above at the intersection of the segments with whitish scales, due
