FALL NUMBER 29 
Pterothorax sub-rectangular in outline, sides converging slightly pos- 
teriorly. Legs moderately long; except the tarsi and fore tibiae which are 
lighter brown, concolourous with the body. Fore femora slightly enlarged. 
Fore tarsi with a small spine. 
Wings well developed. Membrane clear except for a small area at the 
base and the scale of the fore wing which are clouded with brown. Fore 
wing noticeably contracted in the middle; fringing hairs long, 6 or 7 inter- 
located ones. 
Abdomen quite short. The sides of each segment about parallel but ab- 
ruptly contracted at the point of contact with the next. Bristles rather 
short, tube small, terminal bristles short. 
Male similar but fore femora much enlarged and fore tarsal spine robust. 
Sides of the head converging posteriorly. Eyes larger. 
Described from a single female and two males beaten from scrub oak at 
Daytona Beach, Fla., Aug. 1919. Type in the author’s collection. Very 
close to H. Graminis but the color is less yellowish brown and the inter- 
mediate antennal segments are more elongated, especially the third. There 
is a sense cone on the inner surface of the segment 3 but it is thin 
and inconspicuous. The most noticeable difference is in the shape of the ab- 
domen which is much shorter than in H. graminis. 
67. Heliothrips fasciatus. 
A single specimen of this species, which is very abundant in California 
where it is called the “Bean Thrips” because of its ravages on cultivated 
beans, was collected from Cassia at Seabreeze, Fla., Aug. 1919. This was 
far from any cultivated land and there can be no doubt that it is a native 
insect. This is the second report of its presence in the East, Mr. Mor- 
gan having collected it in Tenn. 
68. Heterothrips tiliae, n. sp. 
-?, General body color dark brown, intermediate antennal segments, 
tarsi, tips of all tibiae and entire fore tibiae brownish yellow. 
Measurements: Total body length 0.75 mm. Head, length 0.07 mm.; 
breadth 0.13 mm.; prothorax, length 0.08, width 0.19 mm.; mesthorax, width 
0.23 mm; abdomen greatest width 0.24 mm.; antennae, total length 0.19. 
Segment 1 (exposed portion) 9.5; 2, 28; 3, 48; 4, 38; 5, 29; 6, 26; 7, 11; 
8, 12; 9, 10 microns. 
Head about twice as wide as long, broadest behind the eyes; entire dorsal 
surface conspicuously transversely striate; cheeks bearing several short but 
stout hairs; frons deeply emarginate at the base of each antenna. Hyes 
black, prominent, projecting; hairs between the facets conspicuous, fully 
as large as those on the cheeks. Ocelli large, yellow, prominent. Posterior 
pair contiguous with the posterior inner angles of the eyes; flattened on 
the side next to the eye. Anterior facing forward. Mouth cone reaching 
nearly across the prosternum. Antennae almost three times as long as the 
exposed portion of the head; 9-segmented; segment 1 cup shaped, 2 and 6 
barrel shaped, 3 urn shaped, 4, oblong, 5 ovoid, 8and 9 conical; 1, 2 and 6 
to 9 dark brown, 3 to 5 brownish yellow; 3 nearly colorless at the base, 
4 shaded with brown on apical half; 3 with two deep constrictions near 
the base and many shallow ones above. Bristles and sense cones short and 
very inconspicuous, nearly colorless except those on segment 2 which are 
larger and brown; segments closely united, articulations brown.
