tibiis arcuatis, supra fuscentibus. Abdomen thorace triplo longuis, eoque paulo 
angustius, cylindricum, segmentis 3 et 4 latitudine paulo longioribus, 5-7 quadratis, 
omnibus tuberculis lateralibus subprominentibus. Aculeus longitudine corporis, 
terebra badia.

Calliephialtes comstockii (Cress.). 
The only reference to Calliephialtes comstockii Cresson is the original 
description published in 1880 (4). The type was reared as a parasite of 
Retinia comstockiana Femald. It was referred to the genus Ephialtes. 
Ephialtes comstockii Cresson, n. sp. 
Female.— Black, shining; thorax smooth, very feebly punctured; metathorax 
smooth, rounded, with two abbreviated, longitudinal, feebly developed elevated 
lines on disk, slightly divergent posteriorly; tegulae white; wings hyaline, subiri- 
descent, nervures and stigma fuscous, the latter with a pale spot at base, areolet as 
usual; legs including coxae bright; posterior tibiae and tarsi black; abdomen about 
twice the length of the thorax, distinctly punctured; sides of the second and following 
segments tuberculated; first segment a little longer than broad, broadly excavated at 
base and slightly grooved on disk above; second segment longer than broad, widened 
posteriorly; third and fourth segments quadrate; remainder transverse; ovipositor as 
long as the body; length of body .35 inch. 
Habitat.— Ithaca, N. Y. Parasitic upon Retinia comstockiana Femald. 
Calliephialtes pusio (Walsh.). 
Calliephialtes pusio Walsh was originally described in 1873 (3) in the 
genus Ephialtes without host record, this constituting the only reference 
to the species in literature. 
Ephialtes pusio , n. sp.— ? . Differs from gigas 9 as follows: 
I 1. The size is 1/2 smaller. 2. The face is highly polished and scarcely punctate. 
3. The metathoracic carinse are obsolete, being represented only by a slightly im¬ 
pressed stria extending 1 Is of the way to the tip. 4. The carinae of the first abdominal 
joint are entirely obsolete. 5. The relative proportions of the first 5 abdominal 
joints are quite different, 2-4 being equal in length and each twice as long as wide, 
and 1 about 1/4 shorter, and 5 a trifle shorter than 2-4. 6. The usual tubercles are 
obvious only on 3 and 4, and are much less prominent and round, not elongated. 7. 
The ovipositor is rather piceous than black. 8. The legs are pale rufous, all the 
sutures a little darker, but both trochanters of the front leg, and the outermost one in 
the middle and hind leg, are whitish; and in the front leg the tarsal tip, in the middle 
leg the exterior face of the tibia and the whole tarsus, and in the hind leg the extreme 
tip of the femur and the whole tibia and tarsus, are pale fuscous. 9. The wings are 
subhyaline. Length 9 .60 inch; front wing 9 .36 inch; length abdomen 9 42 inch; 
width abdomen 9 *06 inch; ovipositor .85 inch. 
1 E[phialtes ] messor , n. sp.—Feet rufo-fulvous, posterior tibiae arcuate, female with the ovipositor as long 
as the body. 
In habitus, especially in proportions and in the tubercles of the segments, this species stands midway 
between the preceding [i. e., E. tubercuiatus ] and the following [i. e., E. manifestator ]; in its arcuate posterior 
tibiae it differs from both. 
Length about 7 lines. Head with the palpi fulvous. Thorax with a small testaceous spot at the base 
of the wing; wings testaceo-hyaline, stigma and radius fulvous, base and tegulae stramineous, areolet 
triangular and sessile; legs rufo-fulvous; posterior tarsi fuscous; tibiae arcuate, shading to fuscous above; 
abdomen three times as long as the thorax, and slightly narrower, cylindrical, segments 3 and 4 slightly 
longer than broad, s to 7 quadrate, all lateral tubercles subprominent; ovipositor as long as the body, 
terebra brown. 
A single female sent by Besser from Volhynia.
