 the following notes may be given:

 Family, Entomophthoraceae 



I. Entomophthora (Empusa) pachyrrhinae Arthur. On the larvae of Nephrotoma ferruginea-, 

 a manuscript name.

3. E. (E.} caroliniana (Thaxt.) [= E. arrenoctona Giard]. On an adult male of Tipula 

 entomophthorae. 



4. E. (E.) arrenoctona Giard. On male adults of Tipula paludosa (Giard 1888, Villeneuve 

 ' 1910, Picard 1913).

 Thaxter on larvae and adults of Tipulidae. 



7. E. (E.) sphaerosperma Fres. Recorded by Thaxter from adult Tipulidae. 



8. E. (E.} grylli Fres. Recorded on at least two occasions from the adult flies of Tipula 

 ultima Alex. [= T. flavicans Fabr.]. 



9. E. (E.} punctata Thaxt., ms. On adult females of Pseudolimnophila noveboracensis. 



10. E. (E.} dipterigena (Thaxt.). On the adult flies of several genera of Limnobiinae, as 

 ' follows: Molophilus hirtipennis, Limnophila aprilina, Pseudolimnophila nigripleura, 



Ulomorpha pilosella, Penthoptera albitarsis. 



II. Isaria sp. On adults of Dicranomyia pubipennis. Additional undetermined species 

 of this same genus on various tropical Tipulidae. 



Class, Hyphomycetes. 

 Family, Mucediniaceae. 



12 Sporotrichum densum Link. On Tipula cunclans Say [= T. infuscata Lw.J (Hyslop, 

 1910:130). 



Internal parasites 



Crane-fly larvae and adults are infested by numerous protozoan 

 and bacterial parasites, the more conspicuous and constant being the 

 Sporozoa (Gregarinidae) and the Bacteria. General references to this 

 subject may be found in Leger (1892), Labbe (1899), and Minchin 

 (1903). More especial references are made to the parasites of Ptychoptera 

 by Leger and Duboscq (1909), to those of Dicranota by Miall (1893: 

 237), to those of Ctenophora by Anthon (1908:542), and to those of 

 Tipula by Mackinnon (1913). In the case of Ctenophora the parasites 

 were frequent between the cells of the alimentary canal, especially in 

 the proventricular caeca. The writer has found a large gregarine very 

 abundant in the alimentary canal of the larva of Pedicia albivitta, 

 many of the individuals being very heavily infested. Gamkrelidze 

 (1913 b) records gregarine and nematode parasites in Gnophomyia 

 larvae.
