381] STUDIES ON GREGARINES— WATSON 171 



Frantzius enumerated among his species both G. polymorpha and 

 &. cuneaia Stein, not recognizing that the former included the latter. 

 He did not illustrate the species Gregarina cuneata, but included under 

 the name G. polymorpha one excellent figure of G. cuneata (Fig. 135). 

 Stein said that Frantzius knew all three gregarines in this Tenebrio, but 



" — wirt sie ebenfalls zu einer Art unter dem Namen Gregarina polymorpha 

 zusammen bios aus dem Grunde, weil sie in einem und demselben Thiere leben." 

 He named one of the species Stylorhynchus ovalis. The other two 



" — sind einander sehr ahnlich und fast gleich gross. Die eine ist durch den 

 nach vorn erweiterten, flach gedruckten, keilahnlichen Kopf, der fast Yz der Lange 

 des Leibes gleichkommt, und durch den nach hinten erweiterten Leib ausgezeich- 

 net; ich nenne sie Gregarina cuneata." 



Lankester placed this species and Schneider's 8t. ovalis together 

 as synonyms under the name Gregarina polymorpha Hamm. Schneider 

 grouped together under the name Clepsidrina polymorpha (Hamm.) the 

 three species from Tenebrio molitor, which Stein had separated some 

 twenty-five years before. He designated the species which is under dis- 

 cussion as Clepsidrina polymorpha var. cuneata (Stein). He con- 

 sidered adult associations of G. cuneata as young immature associations 

 of G. polymorpha. 



"Les jeunes individus sont nombreux et remarquables par le volume relatif 

 de leur protomerite (Fig. i6 et 17)." * 



The figure 16 referred to is a typical association of G. cuneata. He says 

 further 



" Resemble beaucoup a la precedente ; est arrondie en arriere au deuto- 



merite et plus massive dans son ensemble (Fig. 11, le primite.)". 



His figure 11, my figure 132, coincides with Stein's figui^ of his G. 

 cuneata, my figure 133. Berndt studied the gregarines of the larva of 

 Tenebrio molitor and isolated G. cuneata from the others. Leger and 

 Duboscq (1904) confirmed his work. (Their drawing is reproduced in 

 my figure 152). 



In Leidy's unpublished manuscript, Crawley (1903) found two 

 drawings of gregarines taken from the Tenebrionid, Xylopinus saper- 

 dioides. One has been otherwise disposed of, but one drawing is of a spe- 

 cies identical with or very similar to G. cuneata. No description or meas- 

 urements accompanied the drawings. From a similarity of the figures of 

 the type G. cuneata and the figure given by Crawley (my figure 134), the 

 species is the same. 



Ishii (1911:279 and 1914:435) found the species in Japan (my fig- 

 ure 36) in Tribolium ferrugineum, one of the Tenebrionidae, and very
