22 IOWA STUDIES IN NATURAL HISTORY 
in June. The species noted under this name by Prof. Stoner in 
Canadian Entomologist, vol. L1, p. 217 (1919) were, at least for 
the most part, the P. brunnea listed below. 
Periplaneta australasiae Fabricius 
Blatta australasiae Fabr., Syst. Ent., p. 271 (1775). 
Periplaneta australasiaes Kirby, Syn. Cat. Orth., vol. 1, p. 141 (1904.) 
One male and two females were taken by Prof. Stoner on Bar- 
bados, one being labelled ‘‘ Pelican Island.’’ 
Periplaneta brunnea Burmeister 
Periplaneta brunnea Burm., Handb. Ent., vol. 0, p. 503 (1838). 
Periplaneta brunnea Kirby, Syn. Cat. Orth., vol. 1, p. 142 (1904). 
Periplaneta truncata Krauss, Zool. Anz., vol. Xv, p. 165 (1892). 
This large brown roach is represented by three adult, one male 
and two female, and three immature specimens all taken on Bar- 
bados, the male and the nymphs on Pelican Island. 
Hebard, Mem. Amer. Ent. Soc., No. 2, p. 178-188 (1917), 
treats the above species of Periplaneta very fully, and on pages . 
14 and 20 of the same publication keys for their separation will 
be found. 
Genus Eurycotis Stal 
Eurycotis similis n. sp. 
Specimens representing both sexes of a roach referable to the 
genus Eurycotis were taken on Antigua, which, while apparently 
related to certain variegated forms of that genus, as the decipiens 
of Kirby, do not agree sufficiently well with any described 
species, either of Hurycotis or the closely allied Pelmatosipha, 
to be considered identical with any of them. This species is 
accordingly here characterized as new. 
Description.—Size medium for the genus. Head not quite hidden beneath 
the pronotum; color yellow with three transverse black bands of various 
widths, one vertical, one betwen the antenne and one between the last and 
the base of the clypeus, the last often somewhat narrower than the others, 
the vertical and interantennal bands rarely more or less interrupted mesially, 
the lower bar turning up laterally along a deep lateral facial fold to almost 
meet the lower edge of the eyes; eyes ashy gray, narrow, reniform, separated 
by a space a little broader than that between th antennal scrobes; ocelli 
obscure, subcutaneous; antenne much longer than the body, uniformly dark 
reddish brown. 
Pronotum truncate posteriorly, where it is somewhat broader than the
