CICADELLINAE: PART 2. NEW WORLD CICADELLINI 385 
S. febris, n. sp., is very closely related to S. salutaris (Fowler) and perhaps 
will be found to be only a subspecies of the latter. §. febris is much larger (the 
length of salutars males varying from 6.0-6.9 mm) and with the head shorter 
and broader. The male genitalia are like those of salutaris in almost every re- 
spect. The lateral pronotal markings of febris differ from those of salutaris in 
that in the latter the stripe is complete, as are the two wider middle stripes. 
Also, there is no corial black stripe parallel to the claval sutural black stripe 
in salutaris. 
Soosiulus decoris, NEW SPECIES 
FIGURE 308, PAGE 384 
Length of male 7.9 mm. Head with median length of crown approximately 
three-fourths interocular width and slightly less than one-half transocular 
width, ocelli located on a line between anterior eye angles, each slightly closer 
to median line of crown than to adjacent anterior eye angle, clypeus with 
muscle impressions not very distinct. Other external structural characters as 
in §. interpolis, n. sp. (p. 374). Male pygofer without microsetae near ventral 
margin; plates not extending nearly as far posteriorly as pygofer apex, each 
with a few uniseriate macrosetae; style extending posteriorly slightly farther 
than apex of connective; connective abruptly narrowed anteapically, not 
keeled; aedeagus symmetrical, regularly curved in lateral view, with ventral 
margin regularly and deeply concave, apex with an apicoventral elongate slen- 
der acute process; paraphyses with a slender elongate stalk, and with a small 
lateral convexity at base of rami which are crescentiform in lateral view, 
abruptly narrowed in their basal third with their apices directed antero- 
dorsally. 
Markings of head and pronotum as in S. azatus, n. sp. (p. 378); scutellum 
with basal angles black (remainder obscured by pin); forewing with a black 
spot on humeral margin, connected by a very narrow black line along com- 
missural margin to a small lenticular transcommissural claval black spot, 
claval suture broadly bordered with black almost to apex and with a sub- 
parallel black line in corium extending into anteapical cells, membrane and 
costal margin black, anteapical area suffused with dark red. 
Holotype male, Pachitea, Peru (RMS). 
S. decoris, n. sp., is closely related to S. falcifer, n. sp. (p. 376) and to S. 
azatus, n. sp. (p. 378), from both of which it may be separated by the 
narrower stalk of the paraphyses, the smoothly curved crescentiform rami of 
the paraphyses in lateral view, and by the abruptly narrowed connective. The 
aedeagus is more regularly concave on its ventral margin than in azatus and 
the apical process is shorter than in falcifer.
