FALL NUMBER 19 
48. Haplothrips graminis Hood. 
The author’sAnthothrips floridenis seems to be identical with this spe- 
cies and as Hood’s description was published a few months earlier it takes 
precedence. 
61. Hoplandrothrips quercuspumilae, n. sp. 
Female. Total length 1.43 mm. General color dark brown with much 
red hypodermal pigmentation; all but segments 7 and 8 of the antennae 
clear brownish yellow; large yellowish brown areas on the inner sides of 
the distal ends of all femora; tarsi light brown. : 
Measurements: Head, length 0.24 mm.; breadth 0.21 mm.; prothorax, 
length 0.115 mm.; breadth 0.32 mm.; pterothorax, breadth 0.38 mm.;abdomen 
width 0.43 mm.; tube, length 0.145, breadth at base 0.07 mm.; at apex 0.038 
mm. Antennae: segment 1, 37; 2, 45; 3, 66; 4, 62; 5, 56; 6, 53; 7, 44; 8, 28 
microns. Total length 0.40 mm. 
Head rounded in front, only a little longer than broad, cheeks slightly 
arched and converging posteriorly, provided with small warts which ccrry 
short spines. Postocular bristles rather short but stout and conspicuous, 
dilated into a small colorless head as are all the other prominent bristles 
except those on the tip of the tube. Eyes rather small, dark red. Anten- 
nae 1% as long as the head. Segments 7 and 8 light brown; seg- 
ment 4 thickest, bearing very few, pale, inconspicuous spines; sense cones 
rather long but very pale and inconspicuous. 
Prothorax very short, less than half as long as the head; sides very 
rounding and bearing a thick, heavy spine. Legs moderately long, nearly 
concolorous with the body except the tarsi which are lighter. The light 
areas on the femora are largest and lightest on the hind femora where 
they occupy half of the length and two-thirds of the width of the femora. 
They are smaller on the middle femora. Fore femora but slightly enlarged. 
Wings moderately long, membrane colorless, not constricted in the middle, 
fringed with long hairs which are double for 7-9 hairs on the fore wings. 
Abdomen short and thick, provided posteriorly with dark, capitate, con- 
spicuous bristles. Tube rather small, bearing six bristles which are about 
as long as the tube and equal number of shorter ones. 
Described from three females collected from “oak runner” (Quercus 
pumuli) near Gainesville, Fla., Aug. 7 and 8, 1919. Type in the author’s 
collection. Paratype in the National Museum. 
This thrips bears a superficial resemblance to H. flavo-antennis (Wat- 
son), but it is the apical segments of the antennae which are dark instead of 
the basal and the intermediate segments are not elongated. 
KEY TO NORTH AMERICAN SPECIES OF HOPLANDROTHRIPS. 
In the key to N. A. species of Phloeothrips (Florida Buggist, Vol 1, No 4, . 
p. 75) those species in Section 1 now go into the genus Hoplandrothrips, as 
does also the author’s Liothrips flavoantennis. The following additions to 
the key will serve to distinguish the species now placed in this genus. 
aa. ‘Segment 3 of antennae shorter than 1 and 2 together. 
1. Antennae mostly brown or only the bases of 3-7 yellow. 
b. bb. and bbb. remain as before. 
2. Antennal segments 3-6 light brownish yellow.—H. quercus- 
pumulae n. sp.
