Pronotum short, longer than the vertex, transversely rugose and impressed, bluntly rounded in front, the posterior margin short and subtruncate. Scutellum bluntly triangular, hardly acuminate, with a few impressed dots scattered over the surface. Wing-covers almost transparent, a little curved, the veins thick and pale yellow, the general surface a little dusky, with a darker streak behind the pale yellow costa, the veins long and regular. Wings a little smoky, with brown veins. Legs pale dull yellow, with the tarsal joints and nails brown. Sternum and venter dark, often black in the male, with the sutures and margins pale ; genital segments of the female pale yellowish; tergum mostly black, with a band of yellow next the tip, and the edges of the segments pale ; genital valve triangular, subacute at tip, the two following pieces uniting to form a long, subconical segment with a rounded tip, and armed with stiff, brown bristles. Length to tip of wing-covers 3|-3| m m . ; width of pronotum 1| mm. Numerous specimens of this species were collected on the island by Mr. Smith. Both of the foregoing species belong to a little group of forms which abound on the marshes and low meadows of the Southern United States, and which deviate more or less in venation and form of wing-covers from the types of Deltocephalus. They can hardly be referred to Cicadula. AGALLIA USTULATA, sp. nov. Form of Agallia quadripunctata, Prov. Mostly brown above, and black beneath.
