250 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. I4I 



He Stated, "The longitudinal dorsal grooves of the scutellum, which 

 are strongly developed in normal hagenowii, are only rather faintly 

 developed in Waterston's type and also the second specimen, which was 

 dissected and mounted on a series of ten microscope slides. No doubt 

 it was this faint development that caused Waterston to describe the 

 species in Tetrastichodes, a segregate that has since been recognized 

 by Dr. Burks (Proc. U. S. Nat. Mus., 1943) as being not truly ge- 

 nerically distinct from Tetrastichus." 



Natural hosts. — Blatta orientaHs, Seychelles (Ratzeburg, 1852) ; 

 India (Usman, 1949). 



Blatta sp., U.S.A., Louisiana (Gahan, 1914). 



Blattella germanica (Burks, 1943; Peck, 1951). [In personal 

 communications, Burks and Peck cite Howard (1892) and Marlatt 

 (1902, and the 1908 revision of 1902) as sources for this host record. 

 However, B. germanica is not mentioned specifically as a host of T. 

 hagenozvii in the sources cited nor in the 1915 revision of Marlatt's 

 1902 paper cited by Burks (1943) ; see footnote 6, p. 236.] 



Neostylopyga rhomhifolia, Hawaii (Pemberton, 1941) : This rec- 

 ord is based on one parasitized ootheca. We have exposed, at three 

 different times, groups of 10 to 20 oothecae of A^. rhomhifolia to many 

 newly emerged T. hagenozvii, but none of the eggs was parasitized 

 (Roth and Willis, unpublished data, 1957). 



Parcoblatta sp., U.S.A., Ohio (Edmunds, 1953a). 



Periplaneta americana, Africa (Crawford, 1910; Nash, 1955): 

 Nash's record was incorrectly attributed to Syntomosphyrum glos- 

 sinae Wtstn., a parasite of tsetse fly pupae (Jordan, 1956), Formosa 

 (Takahashi, 1924; Sonan, 1924); Palestine (Bodenheimer, 1930); 

 Puerto Rico (Sein, 1923; Plank, 1947, 1950; Wolcott, 1951) ; St. 

 Croix, Virgin Islands (Beatty, 1944) ; Hawaii (Schmidt, 1937) ; 

 U.S.A.: Missouri (Ran, 1940a); Ohio (Edmunds, 1955); Florida 

 (parasitized oothecae were collected near Orlando by members of the 

 Orlando Laboratory, Entomology Research Branch, U.S. Department 

 of Agriculture ; the parasites were identified by Burks, personal com- 

 munication, 1955). Fiji (Lever, 1943) ; India (Mani, 1936; Usman, 

 1949) ; Trinidad and Saudi Arabia (Cameron, 1955). Westwood 

 (1839) stated that 70 parasites belonging to the genus Eiilophns 

 emerged from an ootheca of P. americana collected on shipboard. 

 Burks (personal communication, 1955) stated that the wasp was prob- 

 ably T. hagenowii. 



Periplaneta ausfralasiae, Austrnlia (Shaw, 1925) ; India (Usman, 

 1949) ; Saudi Arabia, Trinidad (Cameron, 1955) ; Formosa (Sonan, 

 1924).
