tTPON SCALE -INSECTS. 19 



(b) On Aleurodes, sp., on lower surface of leaves of a 

 jungle tree collected by Macmillan. Pussella, Februarv. 

 1899. 



This specimen was most likely an older stage of (a). The 

 stroma-like mats covering the insects had here and there a 

 distinct red colour. Some of them were as much as 4 mm. 

 in diameter. The perithecia were similar to («), but more 

 numerous, while ascus and ascospore were identical. 



Type 2, resembling somewhat T. tomentosa. 



On Aspidiotus destructor on. lower surface of leaves of a 

 jungle tree, found by Green, Pundalu-oya, 1899 (fig. 5.) 



This type differed from the foregoing chiefly in the colour 

 of its perithecia. These were pale yellow-brown with 

 gelatinous-looking apices. As many as nine were counted 

 around a pustule, either occurring singly or in groups of 

 two or three with coherent bases. The perithecia on the 

 whole were smaller, measuring in length 525^/ and in 

 breadth, lower part 225 p, neck 75 ^. Ascus and spore simi- 

 lar. The whole fungus has a softer and whiter appearance 

 to the preceding type and occurs on quite a different kind 

 of scale-insect. 



The differences between T. rubra, T. luteorostrata, and the 

 red Ceylon form are very slight. Zimmermann says the 

 Java species differs from T. rubra through its perithecia 

 being smaller, having yellow ostioles and in many being 

 grouped on one stroma. 



No conidial stage has been found as yet associated with the 



Oeylon specimens, nor are any described by Patouillard and 



Zimmermann. Boudier* in 1887 discovered a conidial 



fructification {Isaria cuneispora) belonging to T. arani- 



cida. 



Genus Nectria, Fries. 



The first material handed to me by Mr. Green consisted 



of scales of Aspidiotus attacked by a red fungus on twigs of 



a Citrus .shrub. This was in the conidial condition and
