Tfetl druh, Euthrips occidentalis nov. sp., jest asi zastupce rodu Physopus. 
Nalezen byl A. Crawem a D. W. Coquillettem v Kalifornii, kdez poskozuje listy 
bramboru i merunek a zije cetne v kvetech pomerancovych. Popis jeho, Pergandem 
podany, jest nasledujici: 
Euthrips occidentalis Pergande. »Length, 0.9 to 1.2 mm. General color, 
orange yellow, with the posterior margin of the abdominal segments broadly dusky or 
blackish. Eyes hairy, black. Ocelli reddish. Antennae dusky, with base and tip of the 
joints paler. Wings yellowish, the spines and fringes blackish. Head twice as broad as 
long. Eyes very large, occupying about two-thirds or more of the sides of the head, 
and coarsely granulated. Head and pronotum transversely striated. Joints 3 and 6 of 
the antennae longest and nearly subequal in length; the third with a shorlh though distinct 
pedicel. Joints 2, 4, and 5 next in length, also subequal. The last two joints, usually 
termed the stylus, are smallest, though the last is considerably longer than the penul¬ 
timate one. Joints 2 to 5 bear each about six bristles around the apex and the sixth 
about the same number around the middle. Besides these bristles, there may be noticed 
a pair of stout, bluntly pointed, curved, sensorial spines, near the end of joints 3 and 
4, originating from a rather large, membranous spot, similar to those organs in Thrips 
tritici .« 
0 ctvrtem druhu, t. zv. trasnence cibulove (the onion thrips), snasi Pergande 
vse, co o nem dovedeli se mohl, a cituje cetne udaje jedriotlivych oekonomu severo-

ta zije na nejrozmanitejsich mlstech ve Spojenych statech, a sice hlavne na zelenine 
(zvl. cibuli znacne poskozuje), mimo to vsak take na kvetinach zahradnich, na merun-
