oints subequal, the third being the shortest; the club is nearly as long as the two 
preceding joints together; all joints, except scape and pedicel, furnished with long 
non-whorled hairs. Head and mesonotum very delicately but distinctly punctured. 
Color: Head and thorax metallic blue-black, abdomen shiny black; all coxze metallic 
blue-black ; all femora brown, light at tips; all tibie dusky, light at tips, the hind 
tibie darker than the others; all tarsi pure white with dark claws. The stigmal vein 
is longer than the marginal, which is very short and thick. 
Described from 1 ¢ specimen (2? unknown) bred, April 6, 1882, from 
Lecanium sp. on Pinus australis, collected at Archer, Fla. [C. V. R. 
Coll. } 
18. (2) Encyrtus ensifer, n. sp. 
Male.—Length, 0.66™™; wing expanse, 1.75™™; greatest breadth of fore wing, 
0.36™™, Antenne long and furnished with long hairs arranged in two irregular 
whorls; pedicel and flagellar joints subequal in length and about 1.5 times as long 
as broad; the flagellar joints are deeply incised dorsally, giving each a moderately 
strong, rounded, dorsal prominence; the club is somewhat longer than the two pre- 
ceding flagellar joints. Head and mesonotum very delicately and finely punctured. 
Color: Head, thorax, and abdomen shiny dark-brown, nearly black; antenne light 
brownish-yellow; all legs dusky, light at joints; wing-veins dusky, marginal vein 
darkest. Stigmal vein longer than marginal, uncus consisting of four cells. [The 
penis, as shown in one specimen, is somewhat hastate and not bifid as with Hupelmus 
and other chaleids. ] 
Female.—Length and proportions much the same as those of the g. Antenne 
somewhat compressed ; scape not widened; pedicel twice as long as wide and some~ 
what longer than first flagellar joint; all flagellar joints subequal in length and width 
and flattened cylindrical in form; club large, oval, compressed laterally, as long as 
three preceding flagellar joints. Sheath of ovipositor more than half the length of ab- 
domen. In every specimen examined the ovipositor was not contained in its sheath, 
but stretched out from its insertion in the first abdominal joint in a sword-like enrve 
as long asthe whole body. General color as with ¢ ; base of antennal scape dusky, 
tip yellow, pedicel dusky throughout, flagellum light yellow-brown; legs slightly 
dusky, except at ends of joints; ovipositor bright yellow, sheath dark brown. 
Described from 3 ¢, 4 2 specimens, bred June 1 and 5, 1882, from 
Aspidiotus corticalis: Riley MSS., on peach, collected at Crescent City, 
Fla., by H. G. Hubbard. [Dept. Agr. and C.V. R. Coll.] 
19. (3) Encyrtus fuscicornis, n. sp. 
Female—Length, 1.93"™ ; wing expanse, 4.6™™ ; greatest width of fore wing, 0.69™™. 
Punctuation of mesonotum very delicate. Antennal scape slender, not widened, 
marginal vein present, but shorter than stigmal. General color dark honey-yellow ; 
antennal scape dark yellow, pedicel and first three funicle joints fuscous, last 
three funicle joints light yellow, club black and compressed; scutellum dusky and 
and with an irridescent tinge; tegulw dusky at tips; metanotum black; superior 
surface of abdomen black, inferior surface dusky, all legs uniformly yellow. Wings 
fuscous, somewhat clear at base, and with two transverse hyaline streaks, the 
broader of the two, just at tip of stigma, with its proximal border concave and its 
distal border straight, and the narrower one at outer third of wing with its two 
borders parallel.
