SPRING AND SUMMER NUMBERS 69 
This species is about the size of the California species F. minutus as 
given in the original description, but differs markedly in color, position 
of the posterior ocelli, length of the mouth cone, and other characters. It 
is a very distinct species. 
20. Frankliniella occidentalis (Pergande.) (Redescribed by Hinds, ’02, 
Deal S21) 
(Euthrips occidentalis Pergande, ’91). 
Dade City, May 12, 1910, on beans, collected by Hunter and Mor- 
gan. (Morgan, ’13). 
Manatee, March 1911, on mango, H. F. Schultz, collector. (Mor- 
Panewe las) 
21. Frankliniella stylosa Hood. 
(Euthrips floridensis Morgan, 713, p. 5). 
Quincy, on Asclepias variegata L and in blossoms of Catalpa ca-

Extends north to Maryland. 
22. Frankliniella bispinosus (Morgan, 713.) THE 2-SPINED FLOWER THRIPS. 
Described from Dade City where it was taken in blooms of Yucca, 
May 1910. 
Gainesville on oats, April ’14; roses, April 1912; blooms of compo- 
sitae, Oct. 1913. 
Miami, April 1916, on avocado blooms which it severely damages. 
23. Frankliniella bispinosus projectus Watson (Watson, 715.) THE FLor- 
IDA FLOWER THRIPS. 
Gainesville, has been taken every month in the year in roses, and 
could be taken almost any day and in a great variety of blossoms, 
but mostly in those of an open structure. Our most common thrips. 
Begonia (Nov.), tomatoes (March-May), compositae (Oct.-Dec.), 
Aesculus pavia (Mar.), peaches (Jan.-Mar.), Persea (March), peas 
(April), petunias, roses, Cornus floridensis, wild plum (Feb.), 
Cercis canadensis (Feb.), cherry laurel (Feb.), citrus; Ft. Ogden, 
citrus; Gulfport, on sea grape (Cocolobus floridana) Oct. 1913; 
Dania, Ft. Lauderdale and Pompano, on tomatoes, Feb. 1913, White 
City. 
Not usually found in blossoms with a tube but the petunia is an 
exception. Prefers light colored, white or yellow blossoms. 
Certainly most and probably all, the insects that have been men- 
tioned in the Florida literature as EHuthrips tritici belong to this or 
the preceding variety. The writer has not seen typical Huthrips 
tritici from Florida, but has collected it as far south as Swanna- 
noa, N. C., and has it from Atlanta, Ga., and Alvin, Texas. It 
is at once told from either of the above varieties by the second seg- 
ment of the antennae which is asymmetrical. In both of the 
varieties there are on the dorsal surface of this segment, two prom- 
inent spines. In var. projectus in addition this segment is pro- 
longed anteriorally on the dorsal side so as to project over the 
third segment. This is particularly marked in the male. In the 
female the segment is, in addition, very long.
