Couch and Dodge 

 J. Elisha Mitchell Sci. Soc, 63: 75. 1947 



Sporangia 26-31 x 36-58 [x, wall transversely striate in surface 

 view, four-angled in cross section, wavy in longitudinal section; with a 

 distinct preformed longitudinal groove in the outer wall layer on one 

 side. 



In one larva of Stegomyia scatellaris, with C [oelomomyces] stego- 

 myiae, collected by Dr. Lamborn in the Federated Malay States. 1 



In larva of Aedes aegypti (syn. Stegomyia scutellaris). 



Found by Couch on a slide of the type material of Coelomomyces 

 stegomyiae Keilin, from which it differs in shape and in larger size.

 J. Elisha Mitchell Sci. Soc, 63: 75, pi. 19, figs. 4,5. 1947 



Mycelium well developed, much as in the typical species; sporangia 

 roughly oval in outline but with the outer wall crenulated and very 

 irregular, 15-21 by 23-41 jjl, with 4-6 irregular longitudinal ridges 

 between which are numerous transverse lines ; very minutely punctate ; 

 inner wall layer in longitudinal sectional view oval in outline, slightly 

 flattened on one side; outer wall with 4-6 ridges in cross section, inner 

 wall nearly rounded in the same view; outer wall with a distinct lon- 

 gitudinal groove on one of the ridges. 1 



In larvae of Anopheles punctipetmis, United States. 



Considered to be an intermediate form between Coelomomyces 

 quadrangulatus and C. pentangulatus but distinct from either by reason 

 of the very irregular walls of the resting spore.
