He informs me that the two forms Avhich he felt confideot were 

 male and female were taken at the same tune and on the same 

 plant, Iva fnihsccns. While none were observed mating, the fact 

 that they occurred so closely associated and that no other species 

 of the genus was found to occur with them, makes the supposi- 

 tion almost a certainty. Furthermore, they agree so closely in 

 all generic characters that I do not hesitate to regard them as 

 sexual complements and present herewith a description of the 

 male. This differs strikingly in some respects from the female, 

 though no more than is common to many species of Jassidae. 



Male. — Black, pronotum, and eh'tra, except at tip, silvery 

 white with latter barely reaching lo tip of anal style, beneath 

 black, tips of femora and most of tibiae and tarsi, except at the 

 apex, brown. 



Length, 3.5mm. Width, 1.75 mm. 



Head as in female and face very long, pronotum very short and 

 hind border evenly but very slightly convex, scutellum scarcely 

 visible. Legs long, femora and tibiie much compressed but not 

 foliaceous. 



Color. — Head piceous black, the sutures between the vertex 

 and eyes pale, as also the triangular area between the vertex and 

 eye and a narrow margin of the occiput. Front black with mid- 

 dle line slightly paler and sides showing very obscure transverse 

 markings. Pronotum above silvery white, changing to fuscus 

 black on sides. Elytra silvery white to near the apex, apical 

 margin deep piceous black. Abdomen above whitish, anal style 

 light orange-yellow, black at tip, pygofer black. 



The females agree closel}^ with the description of the Florida 

 specimen. The markings appear to vary in the different individ- 

 uals somewhat, and the elytra in these specimens are distinctly 

 brownish between the broad, whitish veins. Ovipositor is black, 

 except a narrow ventral border, the inner faces of tibiae, and 

 somewhat broken line on the femora and the inner face of the 

 hind tibia black. 



The Bermuda specimen appears somewhat darker in general 

 color, the head being somewhat infuscated, the elytral spaces a 

 darker brown, and there is an additional short, broken fuscus 

 stripe on the pronotum between the first and second stripes of 

 either side. The apical spots extend further upon the cells, and 

 one line in the outer cell is elongated and extends fully two-thirds 

 of the length of the cell. These variations seem to me, however, 

 to be entirely within the limits of specific variations. 



The distriliution of the insect based on these specimens would 

 extend from Louisiana around the gulf coast and to Burmuda, 

 and it seems ])robable that it will be found at intervening points on 

 the Gulf coast, especially in the salt marshes where its host ])lant 

 occurs, as well as westward and southward in suitable locations.
