Type-locality.—Tallulah, Louisiana. Female (apterous).—Length dis- tended about mm. General color brown. Head (except anterior region), median portions of pterothorax, apexes of femora, and all of tibiae and tarsi yellow. Antennal segment I light brown, segment II and pedicel of III yellow, remainder of antennae brown becoming darkest apically. Tube, ex- cept tip, orange. Body setae hyaline. Subintegumental pigment red. Head as in Fig. 289, with cheeks smooth. Interocellar and postocular setae pointed. Antennal segment III moderate in size, longer than IV, with one inner and one outer sense cone;. Fig. 289. prothorax. -Diopsothrips husianae, head and segment IV with two inner and two outer sense cones. Prothorax with all major setae pointed. Praepectus, if present, not discernible in the specimens I have seen. Metascutum with faint hex- agonal reticulations. Wing pads en- tirely lacking. Fore tarsi with a moderate-sized tooth. Pelta degenerate, anterior portion lacking, posterior portion hexagonally reticulate. Wing-holding setae pres- ent, slightly sigmoidal in form. All abdominal setae pointed. Tube longer than head, thick, ridged. Female (macropterous).—Un- known. Male.—Unknown. This species has an Allothrips-Mke body, but is distinct in having a long, thick, orange tube.

Despite repeated searches, however, it has not been tak
