SPRING NUMBER 9 
Prothorax large and heavy, nearly twice as broad through coxae as 
on anterior margin, anterior margin strongly coneave. All the usual 
bristles present, only those on posterior angles prominent, anterior mar- 
ginals minute. Meso and metathorax broad and heavy; mesothorax but 
little wider than prothorax through coxae, Wings broad but short, barely 
attaining posterior margin’ of 5th abdominal segment; enlarged toward 
tip, posterior margin with about 87 accessory hairs near tip. Legs of 
medium length; middle and hind. femora strong, fore femora incrassate 
with about 3 short spines near the middle within, surface sparsely clothed 
with smaller spines; middle and hind femora similarly clothed; middle and 
hind tibiae each with two long setae without, set at end of second fifth and 
near tip, respectively; fore tarsus with a much shorter seta without just 
before middle. Fore tarsi with a blunt tooth. 
Abdomen well developed, rather long, with long spines at lateral pos- 
terior angles of 5 to 9—a single spine on 5 and 6 and a pair on 7 and 8; 
9, with the usual circlet, which is nearly as,long as tube; spines on tip of 
tube only about 1/3 as long as tube. | |

Described from two females. Holotype from Cayey, Porto Rico, on 
leaves of Ingavera, 1923. Paratype from Port Cangrejos, Porto Rico, on 
cotton boll. G. N, Wolcott collector of both specimens. 
Named in honor of Mr. G. N. Wolcott, in recognition of his interest in 
collecting this order. 
This species may be readily separated from its congeners by the col- 
oration of the first two antennal segments and by the long setae on the 
front lateral of the anterior ocellus. 
ANOTHER YEAR OF THE CITRUS APHIS 
J. R. WATSON 
(Contribution from the Entomology Laboratory, Fla. Ag. Exp. Sta.) 
Between April 18 and 20 two days of hot, humid weather 
caused such.a severe epidemic of Hmpusa among the green 
aphids of citrus (Aphis spiraecola, probably identical with 
Aphis pomi), as to bring them under practical control. Altho 
the aphids are at this date (May 11) again increasing and may 
injure the “June growth,” the season is getting so far advanced: 
that it is not probable that much more damage will be done this 
year. For several weeks their numbers had been sharply
