uniform aark brown; all coxie black, all femora and tibiwe dark brown, 
light at tips; middle tibial spur nearly white; all tarsi light honey- 
yellow, black at tips; wings perfectly hyaline; wing veins rather light, 
except the short post marginal, which is brown. 
Female.—Length, 1.16; expanse, 2.4™™; greatest width of fore wing, 
0.46™, In punctation and coloration closely resembles the male, ex- 
cept that the tips of antennal scape and pedicel are lighter in color 
than the rest of antenne. 
Described from thirteen ¢, twenty ? specimens reared May 16 to 20, 
1891, from over-wintered cocoons of Bucculatrix thujella Pack., received 
April 25, from J. G. Barlow, Cadet, Mo. 
TETRACLADIA gen. noy. 
Matle.—In its four-ramose antennz resembles Tetracnemus Westwood 
and Tanaostigna How. From the former it is at once distinguished by 
the scapule meeting at tip, and from the latter by its rounded occipital 
ridge and the absence of ring joints to the antenne. Antenne eleven- 
jointed; scape inserted half way between middle of face and mouth, 
slightly broadened below; pedicel conical, its breadth at tip equaling its 
length; joint 1 of funicle very short, broader than long; funicle joints 2, 
3, and 4 very short, each giving out a long branch, of which that from 
joint 1 is longest and stoutest; joint 5 of funicle nearly as long as scape, 
giving off a short branch at tip; joint 6 somewhat shorter than joint 4; 
club as long as joint 5, large, ovate. Antennal grooves converge 
towards front, leaving a regularly rounded ridge; ocelli at corners of 
a somewhat obtuse-angled triangle; eyes very far apart; occipital ridge 
rounded. Dorsum of thorax rather flat; scapule meeting at tips. Sub- 
marginal vein reaches costa at half the wing length; marginal vein 
short, about one-sixth the length of the submarginal; postmarginal 
somewhat shorter than marginal; stigmal slender and very short, 
shorter than postmarginal, descending at a wide angle from postmargi- 
nal and bearing a large and well-marked club. Hind femora of unusual 
thickness. 
Tetracladia texana sp. nov. 
Male.—Length, 1.4™™; expanse, 2.5"; greatest width of fore wing, 
0.46"". Head, pro— and mesonotum very closely and finely shagreened 
and with small sparse punctures; a close row of small punctures 
around border of eyes; genal sulcus absent; entire tergal surface of 
abdomen also delicately shagreened, but without punctures. Color: 
Head, pronotum, and mesoscutum metallic green; mesoscutellum green- 
ish bronze; abdomen and venter of thorax black; scape of antennz 
brown; flagellum black; all coxee, femora, and tibize, black, with faint 
_greenish reflections on cox and femora, and the tips of tibia yellow- 
ish; middle tibialwpur light honey yellow; wings nearly hyaline; wing 
veins dark brown, a dark shade or brownish patch just below marginal,
