Subspecies a.—The form present in the United States and 
always considered to be S. exuberans. Distinguishing characters 
of male: three rows of black cilia behind eyes; cheek vestiture 
black; anterior profile outline of forceps prong gently sinuate 
near tip; the two pairs of distal processes of penis very slender, 
that pair arising centrally quite long (longer and more slender 
than in any other known subspecies) ; posterior spur-like pro- 
tuberance of distal sclerite of penis very prominent (largest and 
longest of any subspecies ) ; first genital segment usually brownish, 
sometimes brownish posteriorly shading into dull orange an- 
teriorly, less commonly dull orange throughout; second genital 
segment dull orange. It is considered best to consider this form 
as exuberans for the present and it is so discussed in this paper. 
Subspecies b—This form has for the distinguishing male char- 
acters the following: Two rows of black cilia behind eyes; vesti- 
ture of posterior portion of cheek white, that of anterior portion 
black; see also figure 13 for characters of penis. The two 
forceps are essentially the same as in subspecies a (considered 
to be exuberans), but the characters of the distal processes and 
distal sclerite are distinctive. 
Examination of specimens of S. dux loaned by Dr. Aldrich and 
of further material subsequently received from Hawaii has con- 
vinced me that the subspecies described by me as S. subtuberosa 
(Proc. U. S. Nat. Mus., vol. 54, pp. 89-92) is identical with it. 
Subtuberosa, therefore, becomes a synonym of dux. 
Ordinarily the brownish color of the first genital segment of 
exuberans (subspecies a) would be sufficient to separate it from 
sarracenoides but when this segment is dull orange in color, the 
only reliable character are those of the forceps and penes. It is 
probably only rarely that the first genital segment of exuberans 
would not show some brownish coloration, at least posteriorly. 
In the figures note that the posterior spur-like protuberance of 
the penis is smaller and more slender and the distal processes 
shorter and thicker in sarracenoides. 
S. lugonensis, herein described, is likely to be confused with 
tuberosa, harpax and dux, all of which have both genital seg- 
ments black. It is at once distinguished, however, by the presence 
of two rows of black cilia behind the eyes, while the first two
