GREGARINA sp. Crawley 

 [Figure 105] 



"Asterophora philica Crawley. Gregarina philica Leidy (1889). It is impos- 

 sible to give a description of this species. Figures 31 and 32 are very plainly of 

 the same gregarine, whereas figure 33 seems almost certainly to belong to a differ- 

 ent species. Further, the form figured by Leidy in 1889 is not so closely like that 

 shown in figures 31 and 32 as to render it certain that the two are the same. I 

 therefore include the three different forms under the same name, giving only the 

 figures and reference, until such time as sufficient material is obtained to determine 

 accurately what the actual facts may be. 



The gregarines figured were about 300 microns long." 



(Crawley, 1003:53). 



The first two gregarines have been described under the name Astero- 

 phora philica (Leidy) Crawley. The third is certainly very different 

 from the others and merits isolation. Its generic position is undeter- 

 mined from lack of data and it is mentioned here simply for complete- 

 ness of the record. 



APPENDIX 



AN UNNAMED DIDYMOPHYES FROM A JAPANESE BEETLE 



In a recent article on the parasites in the intestine of a Japanese 

 beetle, Tribolium ferrugineum F., (Tenebrionidae), S. Ishii (1914) has 

 evidently confused two species of Polycystid Gregarines and designated 

 them by the same name. He described two kinds of associations, large 

 and small, as Gregarina minuta, but from his drawings and measure- 

 ments the specimens are unlike. The protomerite of the primite in the 

 first (Fig. 71) is large, subglobose, nearly flattened on the anterior sur- 

 face, five eighths as wide as the deutomerite at its widest portion, and 

 three fifths as high as wide. Its widest portion is some little distance an- 

 terior to the septum. At the septum, there is a deep constriction, the pro- 

 tomerite just anterior to it being wider than the deutomerite just poste- 

 rior to it. In figure 143, the protomerite of the primite is smaller in pro- 

 portion than in figure 71, hemispherical in shape, widest on its posterior 

 margin, two thirds as wide as the deutomerite at its widest part, and half 

 as high as broad. It is narrower at the septum than is the deutomerite 

 just posterior to the septum. Thus there is a smooth, rounded contour
