1906] OLIVE—NUCLEAR AND CELL DIVISION OF EMPUSA 261 
Fic. 54. A stage in which the daughter-halves appear to be pressed upon 
by turgescent, vacuolar middle portion 
55- A partly polar view of an aidiaidy placed nucleus, showing about 
16 fibrillar radiations extending from the centrosomes. 
1G. 56. A late condition in which the daughter-nuclei have just been sepa- 
rated from each other by a cytoplasmic constriction. The nuclear contents 
occupy a pseudo-synaptic position. 
Fic. 57. Showing in the upper portion of the hypha a resting nucleus and 
in pi gi a late stage of nuclear division 
G. 58. A double cytoplasmic constriction cm taken place so that a vacu- 
ole a with nuclear sap is left between the two daughter-nuclei. 
Fic. 59. A telophase condition. 
Fic. 60. Another telophase condition. 
Fic. 61. Probably a very late telophase, in which the dark rim of the center 
has survived, whereas the achromatic centrosome-portion has disappea 
1G. 62. A late condition of nuclear division which is characteristic of ate 
gated cells. 
Fic. 63. A somewhat later stage, also from an elongated cell. 
Fic. 64. A younger stage, in which the nuclear membrane has been 
indented at the ends of the nucleus distally from the poles. 
Fic. 65. An elongated nucleus in division, in which one pole shows an inden- 
tation. 
Fics. 66, 67, Empusa aphidis. Xt1500. 
Fic. 66. A poorly stained mney showing the division character- 
istic of the prec cells of this 
Fic. 67. An earlier stage of ticato
