See my table from 2 for the other genera. Abbg Kieffer in Wytsman's Genera Insectorurn, Fam. Cynipidae, p. 9, has incorrectly included Sulenas$is Ashm. with the Onychiinae; it is a gemlim Figitine .and not an Onychiine.
SOME APHIDS ASSOCIATED WITH ANTS.
BY WILMATTE PORTER COCKERELL, COLORADO SPRINGS, COL. The species of Lasius which occur here attend both aphids and mealy bugs in large numbers and great variety. During the past two years my husband and I have made somewhat extended observations on the behavior of the ants toward their captives and upon the distribution both of the ants and their prisoners. We .are indebted to Dr. Wm. M. Wheeler for the identification of the ants. The species of ants studied make their nests under flat stones. In this climate
the ants are active during the most of the winter, and live in the corridors under the stones, except in very severe weather, when they retire into their subterranean chambers carrying their aphids and coccids with them. In the long droughts to which this region is subject the ants are obliged in most places, to live far under- ground, and after such a siege the number of aphids and coccids is small. In the summer, which is the rainy season, the ants' nests are often greatly extended and large chambers are made about the roots of plants. FORDA KINGII, sp. nov.
Q Body oval or ovate, gray drab to greenish with sutures inconspicuous. Head not
.distinct from the rest of the body; eyes small but distinct. The whole body including
.antennae is sparsely hairy.
The cauda is a distinct rounded tail decidedly hairy on the end. Legs as in Jvchea lasii.
Antennae five jointed, short, and slender ; first and second joints subequal, third about three times an long as second, fourth about as long as second, fifth with a short cylindrical spur about one half the diameter of the segment and including spur only slightly longer than the fourth. Sensoria distinct. Length of antenna1 joints (I) 60 (2) 60 (3) 131; (4) 60 (5) 7s + 12 (1,
HAS. -Found in nests of .&&s clavger,
flaws, 2bmica sp., L. affte~i-
.canit-s, at Lawrence, Mass,, Andover, Mass., Methuen, Mass. Collected by Mr.
George B. Kingwho writes : "feed on roots of grass in ants' nests under stones ; young are brownish."

9 Body oval or ovate, bright yellow, with sutures more distinct than in I? thgii. Head broad with tubercle below the eye. Eyes small and dark. No hairs on body and
antennae as in F. kivtgii; antennae more slender. Cauda brown and hairy. Length of -antcnnal joints (1) 45 (2) 60 (3) 120 (4) 60 (5) 114 -f- 24. A few hairs are found on the end of joint five.
HAB. - Found at Las Vegas. N. M ., Mar. 24, Oct. 11, and at Las Valles, N. M.. Mar. 22.
(W. V. & T. D. A. Cockerell.)
$ Body oval or ovate, a smooth shining- greenish yellow with sutures inconspicuous. Head broad and subtrun~iite; its front width about half its length and about one fifth its width at point of attachment to body. Eyes moderately large placed near the posterior angle of the head; eyes dark brown or black not on tubercles. ?so hairs on body, legs, or antennae. Length of body 2 mm.
Prothorax set off from the remaining portion of the body by a slight cons,triction or deepening of the suture. Remaining- body scgrne~~ts without distinct markings or structures above ; they grow gradually shorter to the posterior extremity. The cauda is light brown and is not haiiq.
The spiracles are brownish and very distinct. The under surface is colored as the nppw. The upper portion of the beak is light 'brownish yellow, extreme tip dark brown. Legs brown, moderately long'; [.he anterior coxae closely~emhracing the base of the head, the others widely separated from each other by the broad flattened meso- and meta- sternum.
T~vo distinct claws and two tarsal joints on all the legs. Antennnc five jointed; second and third joints nearly subequal, fourth very short, fifth withshort cylindrical spin-about one half the diameter of the segme-nt. The spur has a
few hairs (three or four - very short) at the end. Sensoria on fourth and fifth joints large ;~nd conspicuous.
Length of antcnnal joints (I) 60 (2) 90 (3) 99 (4) (5) IIS + 30.
HAR.- Found, Jan. I 2, on banks of Gallinas River near Las Vegas, N. M., with ~asius americanus.
Collected several times since.
Differs from T. lasii by its light yellow color, small size, eyes on tubercle, and relative .length of antenna1 joints, (I) 30 (2) 60 (3') 56 (4) 30 (j) 90 + 18. HAB. -Beulah, N. M., 8000 ft.
Collected March 28 and several times since. It was thought at first that this was the immature form of 7. lasii but the speci- mens examined contained eggs and smaller specimens of T. ldi. show the third antenna1 joint as long as or longer than the second and the eyes never on tubercles.
