AMIOHK'AN SI'KCIES OF AKADUS (hEMIPTEHA) 
Structure. In re(lesci'il)ing it and iiointino; out the characters 
which sepai-ate it from Jwicstus, Ifergroth-i remarks that Uhler’s 
records ])ertain to the latter, but this is not in all cases true, 
since 1 have seen an example of the present species correctly 
determined by Uhler. hAidently he did not distinguish between 
the two foi'ins, althoui>h both came under his observation. From 
corres])ondence with Mr. Blair, of the British Museum, I am 
convinced that Bergroth is correct in treating calujinosus as a 
synonym of tuhcrcuUJer; drawings made from Walker’s type 
indicate identical structure of the second antennal segment and 
no diff(‘rences in the pronotum beyond the range of ordinary 
variation in the species, (’areful examination of several speci- 
mens indicates that the remarkable structure of the dorsal genital 
s('gment of the female descril)ed by Bergroth, may be inter- 
pnded somewhat differently. It seems to me that the discal 
l)ortion of this segment is not reduced in size, but rather that 
tlie usual transverse suture or margin, between the disc and the 
lobes, is in this species obsolescent, slight indications of its pres- 
ence being sometimes visible under high magnification.

Dislribution. — Biutisu Columbia: Vernon, IV, 28, 1915 (M. II. Kuh- 
inann). 
Description . — Dark brown; jiostero-lateral margins of pronotum, basal 
exiiansions and most of veins of corium, iiosterior margins of oonnexival 
segments, and inner margins of genital lobes, yellowish; first antennal seg- 
ment and basal half of si'cond reddish brown; membrane tlark brown, veins 
bordered inconspicuously with white; rostrum and legs pale reddish brown. 
Head about as long as liroad, longer than pronotum (30 to 2.0); tylus nar- 
I'ow, sides parallel; impri'ssions of vertex broad, indefinite, curvi'd; jiri'ocular 
tubercles distinct; antenniferous spines stout, conical, scarcely divergent, 
the lateral tooth absent ; jiost ocular tvilx'rcles small; base of head with olilipue, 
smooth, pale lines; antennae (fig. 42c) moderately slender, almost as long 
as lu'ad and i)ronotum togidher, the first segment extending beyond middle 
of tylus, th(‘ length of the second about eiiual to width of head including 
one eye. Pronotum (fig. 42d) flattened, lateral margins minutely granulate, 
itioderately (‘xpanded and rellcxed; carinae distinctly elevated. Scutellum 
much longer than |)i'onotum (3.0 to 2.o); sides moderately elevatetl, sinuate 
behind middle, manly i)arallcl in basal third; ajiex rounded; base scarcely
