REPORT OF THE STATE ENTOMOLOGIST I9Q12 149 
Tritozyga sackeni Felt 
iwrunelt, &. P. N: Y. Ent. Soc, Jour., 19:32 
This unique form represents a valid species, and though mutil- 
ated it seems preferable to bestow a specific name and publish the 
characters so far as they can be determined, particularly as this 
procedure fixes the identity of the genus beyond all question and 
removes the danger of another synonym being added to an already 
overburdened nomenclature. 
Male. Eyes black; occiput brown. Antennae short, with 9 seg- 
ments, the basal ones pale yellowish, the distal brown; first segment 
small, subglobose, the second distinctly enlarged, ovate, the third 
subcylindric, with a length three-fourths its diameter, the fourth 
with a length a little greater than its diameter, the fifth about the 
same length as the fourth, with a scattering subbasal whorl of 
rather short, curved setae; subapically, on the posterior face there 
is an irregular group of oval, tuber- 
culate elevations, possibly a special 
sense organ. Terminal segment / 
evidently composed of three closely 4: 
fused segments, with a length fully 
six times its diameter and whorls of 
stout setae similar to the subbasal 
one above described near the basal 
fourth, the middle and the distal 
fourth of this compound segment. 
Palpi yellowish, probably quadri- 
articulate, the first probably with a 
length one-half greater than its diameter, the second short, the 
penultimate cylindric, with a length about four times its diameter, 
the terminal as long as the preceding, slightly dilated apically and 
with a few coarse setae; three small ocelli. Mesonotum dark brown. 
Scutellum yellowish, sparsely setose. Wings hyaline, length 1.5 mm; 
costa dark brown, rather densely haired; subcosta uniting with the 
anterior margin near the basal third, the third vein apparently 
united with subcosta near the basal fourth and joining the anterior 
margin near the distal third; both this and subcosta heavy, dark 
brown and sparsely haired. The fourth vein rather distinct, slightly 
curved, its posterior branch an almost direct continuation of the 
basal portion, while the anterior branch arises at a nearly right 
angle, and after describing a broadly S-shaped curve, unites with 
the anterior margin near the distal fifth; fifth vein nearly straight, 
joining the posterior margin at the distal fourth, the sixth vein 
stout, irregularly curved and uniting with the posterior margin 
near the basal half. Halteres probably yellowish, the stem long, 
curved, the distal portion spatulate. Coxae yellowish ; femora, tibiae 
and tarsi yellowish brown, the latter with five segments, the first 
longer than the second, the claws probably simple. Type in the 
Museum of Comparative Zoology.
