comprised the only specimens of /. hubbardi yet secured with the 

 wings attached. The date of this initial find was October 20, 

 1918. A fortnight later, November oth, he collected additional 

 dealated adults and apterous unchitinized specimens under the 

 bark of a pine stump near Wallisville in Chambers County. He 

 also secured a single apterous unchitinized adult female ten miles 

 north of Liberty on November 20th. In Florida Mr. Barber took 

 one adult and one nymph of the apterous form at Timm's Ham- 

 mock, or Naranja, on February 24, 1919, and at the same place 

 and date Mr. Alex. Wetmore took one dealated female of the 

 alated form and one apterous adult form. On March 1st Mr. 

 Wetmore collected again at this locality and took a number of 

 apterous specimens. Mr. T. E. Snyder collected specimens of 

 the apterous form in Florida at the following localities : Princeton, 

 February 24th; Miama Beach, February 28th, and at Ortega, 

 near Jacksonville, March 5th, all in 1919. 



Adult of Winged Form (Female, Male Unknown) (Figs. 1, 2.) 



The general appearance of the winged adult is very well repre- 

 sented by Figs. 1 and 2, the latter depicting the lateral aspect 

 of a dealated specimen. 



This winged form differs fundamentally from the apterous form in various 

 ways; the head differs very little in shape from that of the apterous form, 

 the apparent difference shown in Fig. 1, as compared with Fig. 4, being 

 due to the different angles at which the head was viewed while being drawn. 

 In the winged form, however, there are well developed and clearly fasceted 

 eyes and three prominent ocelli, the latter situated in the form of an anter- 

 iorly directed triangle, as shown in the illustrations; the ocelli are moderately 

 protuberant, projecting noticeably beyond the level of the surrounding sur- 

 face of the head. The eyes are large, the fascets visible under a moderately 

 high magnification, and in alcoholic specimens usually appear as if surrounded 

 by a whitish area of varying width; this light area, however, disappears almost 

 entirely when the specimen is dried, and then is seen to form a part of the 

 eye itself and not an area surrounding it. Fig. 2 was made from a specimen 

 in spirits. 



The antennal structure is practically as in the apterous form, as is also the 

 armature of the posterior femora, the form of the dorsal thoracic segments, 

 however, as might be expected, differs very decidedly from that of apterous 

 individuals, as shown by the figures. The whole insect is here quite heavily 

 chitinized, the general color being blackish, a decided contrast to the scarcely 

 chitinized whitish colored apterous specimens. 



The wings have a reduced venation quite different from that of allied or- 

 ders of insects; the figured specimen shows the venation better than any 

 description can portray it. The wings are evidently habitually shed, as in 

 the Termites, as 15 of the 18 adult specimens examined "are dealated, only the 

 stubs of the wings remaining. The fracture of the wing does not take place at
