Holotype male, Benevides, Para, Brazil, (Gounelle), February, 1895, one 
topotypic female; two females and one specimen without abdomen, Para, 
Brazil (MHNP). One male and one female, Para, Brazil (MMB). Four fe- 
males, Fontebéa and two females, Teffé, NW. Brazil, and one female, 
Yurimaguas, Peru (RMS). One female, Para, Brazil (USNM). 
S. ruber, n. sp., is closely related to S. hastatus, n. sp., in the discussion of 
which distinguishing characters are treated. I am not certain that the females 
from Yurimaguas and the upper Amazon Valley are conspecific with the 
(typical) specimens from Pard. They differ only in that the posterior margin 
of abdominal sternum VII is less convex and the elongate stripe of the fore- 
wing is narrower than in the typical form. 
Soosiulus klagesi, NEW SPECIES 
FIGURE 313, PAGE 391 
Length of male 7.3-8.0 mm, of female 7.2-7.7 mm. Head with median 
length of crown from slightly less than six-tenths to almost seven-tenths inter- 
ocular width and from slightly less than four-tenths to almost one-half trans- 
ocular width, ocelli located before a line between anterior eye angles, each ap- 
proximately equidistant from adjacent anterior eye angle and median line of 
crown, clypeus with muscle impressions distinct. Thorax with pronotal width 
approximately equal to transocular width of head; forewing with membrane 
including inner apical cell and apical portions of remaining apical cells. Male 
pygofer with a small group of very minute microsetae near basiventral 
margin; plates not extending nearly as far posteriorly as pygofer apex, each 
with approximately six uniseriate macrosetae; style extending posteriorly to a 
point more than one-half length of connective; connective slightly constricted 
near base and abruptly narrowed anteapically, with a median keel in apical 
one-fifth of length, aedeagus symmetrical, shaft abruptly narrowed in basal 
third in ventral view, in lateral view regularly arched with apex directed 
posteroventrally, completely without processes, paraphyses with a very short 
stalk, in lateral view with each of rami broadest at midlength, gradually 
tapered and acute in its apical half. Female abdominal sternum VII with a 
median convexity extending to apical margin, its apex convex, posterior 
margin on each side transverse and rectilinear. 
Color of crown and pronotum as in S. hastatus, n. sp. (p. 387), the orange 
marking of the scutellum forming a median sagittate area; forewings with 
humeral margins each bearing a narrow angular black spot which is con- 
nected narrowly along commissural margin with a transcommissural lenti- 
cular claval black spot, with a stripe on claval suture, broadening apically and 
abruptly narrowing at apex, the membrane, a spot in anteapical cells (oc- 
casionally connected with claval suture stripe), black. 
Holotype male, six additional males and one female, Santarém, Brazil, 
June, 1919 (S. M. Klages); one male, Villa Braga, Brazil, December, 1919 
(CM). One female, Itaituba, “Peru” (!) (MMB). One female, “‘Amazon” 
(HNHM). One male, Itaituba, Brazil (RMS).
