UPON SCALE -INSECTS. 15 



out that cultures of this fungus might be employed as a 

 check against this insect, and suggesting how experiments 

 might be carried out. He refers the fungus to Cephalo- 

 sporin™, and names it provisionally G. Lecanii. Numerous 

 examples identical with this have been found in Ceylon. 

 Since then the same [author has described* systemati- 

 cally several Ascomycetous fungi belonging in the main 

 to the group Hypocreales, parasitic on scale insects in 

 Java ; these will be referred to in detail under their 

 respective genera. 



Guegnen| in an exhaustive work on fungous parasites 

 of man and animals published last year gives an account of 

 a new conidial form, Acrostalagmus coccidicola, found by 

 him on a coccid in a greenhouse in Paris. 



The most recent contribution to the subject is a paper 

 by DopJ on a new fungus parasitic on Aspidiotus from 

 Martinique. The advent of the fungus has practically saved 

 the cocoanut palm cultivation in this Island. The author 

 refers it to the genus Hyalopus ; thus it is probably near 

 akin to Cephalosporium. 



Previous to the stimulus given by Mr. Green to the study 

 of these fungi, the Ceylon forms had received no attention. 

 The only mention of such a position for a Ceylon fungus 

 occurs in a systematic paper by Berkeley and Broome§ on 

 some fungi received from the Island. A species of Nectria 

 is named as apparently growing from some coccus. 



In the present paper the various fungi associated with 

 scale-insects are taken in systematic order. The ones 

 which have been described elsewhere by different observers 

 are referred to briefly, and then the Ceylon forms similar to 

 these are treated at some length and compared with them. 

 Though an attempt is made to discriminate between species,
