36. DARBANUS Am. et S. 
Am. et S., 370; Provancher, 183. 
VanDuzee who has recently had an opportunity to examine the Provancher 
collection of Hemiptera, publishes his conclusions in the Canadian Entomolo- 
gist, Nov., 1912. He says the Provancher’s specimens of Bar'banus palliatus 
Prov. and D. georgiae Prov. are both ''Diplocodus luridus Stal” (listed above 
as Zelus exsanguis) and that Zelus marginata Prov. is, as suggested above, 
Z. cervicalis Stal. The former opinion disregards without explanation Prov- 
ancher’s separation of these species from ^^Diplodus” on the basis of the arma- 
ture of the pronotum. Should these species still prove to be valid they should 
be placed as a subgenus of Zelus, distinct from the subgenera given above. 
37. NOTOCYRTUS Burm. 
Burmeister, 227; Stal (f) 69, 84; Champion, 262. 
The species of this genus may be recognized by the inflated posterior lobe 
of the pronotum which covers both the anterior lobe and the scutellum. Only 
one North American species is reported. 
N, DORS-ALis Gray, var. dromedaeius Stal (=N. vesiculosus Perty). Head with 
two long spines; pronotum with posterior lobe greatly inflated, emarginate in 
front, produced laterally into a curved horn-like process and strongly depressed 
on the disc before and behind the middle. In the variety the pronotum is 
entirely black and is not, as in the more southern varieties, marked to some 
extent, with yellow. Mexico. 
38. DEBILIA Stal. 
Stal (f) 68, 84; Champion, 265. 
D. EUFESCENS Champion. Mexico. Eyes small in males; body slender, ver^ 
milion red; segment 6 armed laterally with a long spine. 
39. RICOLLA Stal. 
Stal (f) 68, 77; Champion, 266. 
A tropical American genus with bispinous knees and the first five (six in 
the female) abdominal segments armed with a spine at the outer apical angles. 
R. siMiLLiMA Stal. Mexico, Central America and Costa Rica. May be sepa- 
rated from a nearly related species {R. palUdipennis) by the lack of a conical 
tubercle at each of the anterior angles of the pronotum. 
40. REPIPTA Stal. 
Stal (f) 69, 80; Champion, 267. 
An American genus very closely related to the two preceding genera and the 
one following. The four North American species may. be separated as follows; 
a. Head with two short spines or tubercles. 
b. Legs unicolorous, black; corium, clavus and rostrum black are black- 
ish; size large.,... 1 . fuscipes Stal 
bb. Legs sanguineous, annulated with black; corium and clavus partly 
fuscous; size small 2. nigronotata Stal 
aa. Head with two long spines. 
b. Legs black, except femora sometimes at base; posterior lobe of
