 Blattella germanica, U.S.A. (Crawley, 1903) ; South Africa (Fan- 



tham, 1929 ; Porter, 1930 : these appear to be the same record).

Parcohlatta pensylvanica, U.S.A., Michigan (Ellis, 1913a). 



Cockroaches, Germany (Schififmann, 1919: probably used the ori- 

 ental cockroach) ; Venezuela (Tejera, 1926). 



Organism usually found in the intestinal tract of cockroaches where 

 it is attached to the gut cells. Cysts are passed in the feces. Occa- 

 sionally, G. bhittarmn (fig. 2, J) is found in the body cavity (Leidy, 

 1853a; Hall, 1907). Though this is considered to be one of the 

 commonest of the Sporozoa encountered in cockroaches, DeCoursey 

 and Otto (1956) found only 10 of 217 P. americana and B. german- 

 ica, collected in restaurants in Egypt, infested with this species. Wat- 

 son (1917) found a dozen or more in one specimen of Blatta ori- 

 entalis. Zasukhin (1929, 1930) found 2.6 percent of 3,000 oriental 

 cockroaches infected with this parasite. 



Gregarina fastidiosa Harrison 



Natural host. — Aptera fusca, South Africa (Harrison, 1955) : All 

 mature females were heavily infected; in all specimens there were 

 over 100 parasites in the gut. All nymphs were infected, the earlier 

 instars more lightly than the later instars. Gregarines were found in 

 all parts of the gut except the crop and gizzard. 



Gregarina gibbsi Harrison 

 Natural host. — Temnopteryx phalerata, South Africa (Harrison, 

 1955) : Although the cockroaches were found in groups, only 32 per- 

 cent were infected and only 10 percent heavily. The gregarines were 

 found in the anterior mesenteron but none in the hepatic caeca. All 

 cysts w^ere found in the hind gut or rectum.
