Maxillary stylets retracted far into the head, nearly parallel with- in the head. Prothorax with anterolateral and major posterior setae long and dilated, anteromarginal setae well developed but only slightly more than one-half as long as anterolateral setae, midlat- eral setae minute. Metanotum faintly but definitely longitudinally striate medially. Fore legs unarmed. Pelta divided into three parts (Fig. 278). Only one pair of wing-holding setae on each of abdominal tergites III-VII. Abdominal tergite IX with major posterior setae long, the middle pair dilated, the lateral pair pointed. Tube relatively short and slender. Male (macropterous).—Length distended about mm. Similar to female in general color and structure. Abdominal sternite VIII apparently without a differentiated glandular area. Abdominal tergite IX as in fe- male, major lateral posterior setae not shortened. Of the two specimens in the type series in the Watson collection, the one selected here to be the lectotype is labeled "Type &, Gainesville, Fla., III-28-37, J. R. W., Sp. moss, S. W. Station ; The other slide marked "Type 9 " is actually a male collected according to the label "2- 14-37," not "April 4, 1937" as stated in the protolog. Freeriella minuta is one of the most distinctive thrips in Illinois. It can be easily recognized by the characteris- tics of its small size, the cup-shaped form of antennal segment III, and its.

Another form (or undescribed species), with a darker head, has been taken in Vera Cruz, Mexico (INHS collections). The remainder of the spe- cies in Preeriella occur in South America. First known from Florida, minuta has since be
