material upon which this paper is based, but also for making important 

 suggestions about the identity of some of the species. The material 

 credited to J. F. G. Clarke was collected with the aid of a National 

 Science Foundation grant. 



Subfamily Natiobiellinae 

 Genus Notiobiella Banks 



Notiohiella rubrostigma Navas 



Notiobiella rubrostigma Navas, Broteria, Ser. Zool., vol. 12, p. 228, 1914. 



One 9, Almirante, Panama, Nov. 24, 1952 (F. S. Blanton), in 

 alcohol. One specimen, pinned, without abdomen, San Salvador, El 

 Salvador, without date (P. A. Berry). 



These specimens are compatible with the description of rubrostigma 

 Navas as well as with that of callangana Kimmins (Ann. Mag. Nat. 

 Hist., ser. 11, vol. 6, p. 227, fig. 5, 1940), and I tentatively list them 

 under the older name. It is impossible to tell whether or not this 

 is the same as callangana Kimmins since the only difference given by 

 Kimmins concerns the shape of the anal plate of the male. 



Forewing nearly 6 mm, long; membrane tinged with brownish and 

 with three perceptibly lighter zones across the wing. Costal cross- 

 veins partially fuscous, those near base and humeral recurrent vein 

 totally fuscous; basal subcostal crossvein, crossvein between Cui and 

 Cu2, and crossvein connecting first and second radial sectors near 

 base of latter distinctly marked with dark brown; forks of longitudinal 

 veins marked with light brown. Pterostigmatic region containing a 

 carmine red spot contiguous to subcosta. Length of hindwing 4 mm. ; 

 pterostigmatic area elongated and totally carmine red; a single discal 

 crossvein between R44-5 and M1+2, not between M (procubitus) and 

 Cui as given in Navas' original description, probably erroneously. 



Subfamily Hemerobiinae 



Genus Sympherobius Banks 



Sympherobius barberi (Banks) 



Hemerobius barberi Banks, Proc. Ent. Soc. Washington, vol. 3, p. 241, 1903. 

 Sympherobius barberi Banks, Trans. Amer. Ent. Soc, vol. 32, p. 42, 1905. — 



Carpenter, Proc. Amer. Acad. Arts Sci., vol. 74, p. 235, fig. 35, pi. 1, fig. 9, 



1940. 



One cf, Sonora, Mexico (P. H. Amaud); 1 9, Cuemavaca, Mexico 

 (N. L. H. Krauss); 1 9, Tejupilco, Mexico, June 20, 1933 (H. E. 

 Hinton and R. L. Usinger) ; 7 specimens, Mexico, with no further 

 datum; 1 cf, Monterey, Mexico (E. A. Schwarz); 1 9 and another 

 specimen without abdomen, Clarion Island, Mexico (H. H. Keifer);
