from Florida, sent to me l^y Mrs. A. T. Slosson, the postero- 
lateral margins of the pronotum are of a form intermediate V)e- 
tweeii the conditions shown in fip;s. 47d and 4Sd, while in all 
othei' respects the specimen is typical. The remnants of the 
^enital lobes in Ihn-groth’s type lack the spiracles normally situ- 
ated on the marjiin and the apical edges show some signs of al)- 
normality when viewed under the highest powers, so that the 
aberrant nature of the specimen may possibly be due to an in- 
jury occurring perhaps during one of the later nymphal stages. 
Hergroth writes: “I have not seen the male of this species and 
do not know how it is to be distinguished from ahhns cf ; yet 
breviatus does not seem to be an al)normal specimen of aJ)l)as, 
as the female genitalia are quite symmetrical on each side”; 
and I agree that in the alisence of adecpiate material from Florida 
judgment must be suspended. It is worthy of mention in this 
connection that in one example of lugubris which has come under 
my observation the genital lolie of one side is similarly abbrevi- 
ated.

Description . — Black or dark brown, the heinielytra contrastingly pale; 
second and third antennal segments darker toward tiji, sometimes very 
narrowly and inconspicuously pale at extreme apex; oblique pale lines at 
ba.se of head very distinct; cells of corium hyaline, the veins yellowish or 
brown; base, apex, and more or less of lateral margin of corium beyond basal 
third, dark brown; clavus hyaline, dark at base and apex; membrane hya- 
line, with very faint brownish maculation; apical angles of connexival seg- 
ments yellow, conspicuously in female, obscurely in male; rostrum and legs 
dark brown; ventral surface dark brown, sometimes marked with yellow 
along sutures, connexivum spotted. 
Head a little, or scarcely, longer than broad, about as long as pronotum; 
tylus moderate in size, slightly bulbous; impressions of vertex short, nearly 
])arallel, widely separated, connected jiosteriorly ; preocular tubercles dis- 
tinct, rather acute; antenniferous sjiines small, slender, moderately diver-
