a round nicsal H])ot which \h farthcr froin the dif^tal

is longer than in maryLcmdicufi but not quite twioo 
the longth of the first crows-inarking. Legs as in züizaq 
except that the middle of the dorsal cdge of the hind 
feniur is narrowly mctallic green. Funicle 1 somewhat 
longer than over 2'/4 tinios longer than wide. Head 
with the usual punctures. Mandibles 0-dcntate. Fore 
wings with an indefinite brownish cloud against the 
end of the marginal vein. Spurs on caudal tibiae dorsad 
interlacing to form linear areas of yellow. Tegulae 
partly white. Hind femur partly green near center 
of ventral edge. Scape yellow, rest of antennae black. 
From two females in the U. S. N. M., taken at 
Jacksonville, Florida. 
Type: Catalogue No. 20000, U. S. N. M., a 
female on tag. Paratype-1 fumale on tag, a fore wing 
and the head on a slide. 
Elasmus pulex new species. 
Fe male: Length, 175 mm. 
Like varius Howard but the fore wings are distinctly 
infuscated (from base out to apex of venation excej^t 
caudo-distad), the dorsal abdomen ig metallic except 
an orange stripe across a short distance out from base 
(shorter than the basal green stripe) and an ovate 
orange area which fills the disk slightly distad of the 
middle and whose broad end is proximad; also the 
legs are all pale except the dorsal edge of caudal coxa, 
the same of caudal femur and the middle coxae. The 
mandibles are 6- and 7-dentate in varius, here also. 
Scape pale, dusky along its dorsal edge. Pedicel twice 
longer than wide, longer than funicle 3 nearly, the 
latter subequal to 2, 1 about thrice longer than wide. 
Head punctate in both species. Black spines on caudal 
tibiae, doisal aspect, forming two very elongate 
diamonds which are subequal and end to end. They 
form three parallel wavy lines in varius. Compared 
with the type of the latter. 
From one female captured October 24, 1915 by 
sweeping grass in forest, Pi'ince George County, 
Maryland.

Tachardiaephagus thoracicus new genus and species 
of the Ectromini. Genotype. 
Female: — Length, 1.45 mm. 
Orange yellow, the wings slightly, uniformly em- 
browned, the following parts dark metallic green-blue : 
The head, pronotum, cephalic fourth or third of scutum 
(except laterad), abdomen and an irregulär yet broad 
stripe across scutellum between middle and apex. 
Antennae brown yellow, the club black. Venation 
yellowish. Body very finely scaly, the scutum and 
scutellum with moderately dense, short pubescence 
from numerous minute punctures. Axillae distinctly 
separated for a short distance. 
Pronotum transverse, distinct. Scutellum obtuse 
at apex. Scapo long and shinder, not reaching tho 
c(!phalic oc(illu.s; pedicol about thrice longer than wide, 
longer than funicle l by a littlc, the latter «ubequal 
to 2 and long(!st, each 2'^ timcs longer than wide, 
Ii longer than 4 by a little, twice longftr than wide, 
0 slightly longer than wide. Club wid(!r than tho 
funicle and about half its length. Mandibles as in 
Anagyrus but the apex of the second tooth is con- 
siderably concaved. Face inflexed, the scrober long, 
ap])roaching above. Frons not prominent, moderate 
in width. Cheeks nearly as long as the eyes. Head 
(cephalic aspect) round. Marginal vein twice longer 
than wide, subequal to tho postmarginal (or a little 
shorter), the stigmal somewhat longer, well developed. 
Oblique hairless line distinct, the cilia numerous 
proximal of it. Abdomen short, triangulär, deprcssed.

N. M., labelled „Type No. 13242, U. S. N. M., E. E.

Type: Catalogue number as above and a slide 
bearing a fore wing and a head. 
Subfamily Aphelininae. 
Marietta leopardina Nietner. 
The tarsi are 5-jointed, the antennae 6-jointed. 
Venation as in Perissopterus and this genus is the 
same as Perissopterus. General color dull yellow; 
legs spotted (middle legs-femur with a very long spot 
about middle and a small double spot near apex, all 
ventrad; tibia with three faint rings accented above, 
the first near base, the other two not far apart and 
not far distad of middle ; spur black, distal third white ; 
tarsi black, joints 3 and 4 silvery white). Scape black 
above, pedicel also and at apex; otherwise silvery; 
club 1 with distal half silvery white ; 2 with a silvery 
annulus between middle and apex ; club 1 a half longer 
than wide, subequal to the pedicel. Ovipositor valves 
projecting slightly, black. Scutellum with it distal 
margin black. Caudal femur with four round spots 
laterad, two central and opposite, the caudal tibia 
marked about as the middle one except that the basal 
band is represented by the dorsal spot alone. Abdomen 
black above and spotted. Wings as in Perissopterus 
but mutilated beyond the venation.

The very poor original description of this species 
of course leaves in doubt whether the foregoing spe- 
cimen is really it but the crude figure and the descrip- 
tion agree in general and there is but little doubt in 
regard to the genus. 
Coccophagus perflavus new species. 
Female: — Length, 0.55 mm. 
Uniformly golden yellow, the wings hyaline, the 
venation pale yellow. Pedicel subequal to funicle

wider than the funicle, its joints about as long as fu- 
nicle 1. Proximal tarsal joint long. Fore wing uni- 
formly ciliate, with an obscure, not quite complete, 
hairless line from the base of the marginal vein, the 
latter somewhat shorter than the submarginal, the
