1856. Phloeothrips Mali Fitch, Report on the noxious insects of New-York, 
pag. 104. 
Fitch: »This insect measures only six hundredths of an inch in length and 
one hundreth in width. It is polished and shining, and of a blackish purple color. Its 
antennae which are rather longer than the head and composed of eight nearly equal 
joints, have the third joint of a white color. The abdomen is concave on its upper 
side, and is furnished with a conical- tube at its tip which has a hew bristles projecting 
from its apex. The wings when folded are linear, silvery white, and as long as the 
abdomen; they are pressed closely upon the back, spreading asunder at their bases, 
and appear like an elongated white Y-shaped mark. Viewed from above, the head is 
of a square form, longer than wide. The first segment of the thorax is well separated 
from the second, is broadest at its base, and gradually tapers to its anterior end, where 
it is as wide as the head. The following segment is the broadest part of the body and 
square, with its length and breadth equal. United States: New-York.« — Gouging into

pag. 308.; fig. g. 
Fitch: »Length 0.07. — It is of a black color, polished and shining, with the 
third joint of its antennae white, and its wings black or dark smoky brown, with three 
broad white bands, whereof one is upon the base, another across the middle, and the 
third, which is somewhat narrower, upon the tip. The wings show two longitudinal 
veins, but no transverse ones were noticed upon them -(?), nor could I discover any 
fringe upon either their outer or inner (?) margin. The fore legs are larger than the others, 
and the antennae instead of arising far apart as in most of the species I have examined, 
come out from the front of the head close together (!), and are composed of only five
