University of Rochester, Rochester, N. Y. 
The types of the two new species described below are in the author’s 
collection. 
Taeniothrips vaccmophilus sp. nov. (Fig. 1) 
Female (macropterous) . — Length about 0.88 mm. (dis- 
tended, 1.01 mm.). Color clear pale yellow, with tip of ab- 
domen and sides of thorax just perceptively darker ; antennae 
concolorous with paler portions of body in segments I and 
II, III similarly pale at base, lightly shaded with gray dis- 
tally, IV pale in basal third or fourth, more darkly shaded 
with gray beyond but somewhat paler in apical portion, V 
somewhat darker than IV, more briefly pale at base and with 
the short pedicel gray, VI about concolorous with darker 
portions of V, somewhat paler basally, VII and VIII uniform 
gray but paler than VI ; wings of fore pair nearly colorless 
in basal fourth, yellowish beyond, the anal area (scale), a 
narrow line along posterior margin in distal three-fourths, 
and a broader patch along anterior margin of second fourth, 
light gray ; ocellar pigmentation bright red. 
Head about two-thirds as long as greatest postocular 
width, distinctly broader across eyes; cheeks smooth, nar- 
rowing only slightly to eyes, roundly converging to the dis- 
tinctly narrower base, thus not swollen ; occiput with about 
five faint transverse lines of sculpture, of which the an- 
terior is the most distinct; vertex slightly elevated in the 
ocellar area, distinctly excavated between it and insertion 
of antennae; frontal costa with an exceedingly minute V- 
shaped notch; interocellar setae short and pale, about lBp 
in length and somewhat shorter than postocellars, a similar 
but more minute pair of setae near inner margins of eyes
