He informs me that the two forms wliich he felt confident were 
male and female were taken at the same time and on the same 
plant, Iva fridesccns. 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 strikinglj- in some respects from the female, 
though no more than is common to many species of Jassidae. 
Male. — Black, prouotum, and elytra, except at tip, silvery 
white with latter barely reaching to tip of anal style, beneath 
black, tips of femora and most of tibiae and tarsi, e.xcept 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 ver}- slightly convex, scutellum scarcely 
visible. Legs long, femora and tibiae much compres.sed but not 
foliaceous. 
Color. — Head piceous black, the sutures between the vertex 
and e5'es pale, as also the triangular area between the vertex and 
eye and a narrow margin of the occiput. Front black with mid- 
dle line slightl}' 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 closely 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 distribution of the insect based on these specimens would 
extend from Louisiana around the gulf coast and to Burmuda, 
and it seems probable that it will be found at intervening points on 
the Gulf coast, especially in the salt marshes where its host plant 
occurs, as well as westward and southward in suitable locations.
