designate a specimen of the other species as the lectotype would 
bring about a disagreement between the lectotype and the original 
description. For this reason, I designated an EL. simplex Coquillett 
specimen as the lectotype of EH. americana Darlington and thus re- 
tained the synonymy between the two. 
Mayr, Linsley, and Usinger (19538, p. 241) cited a suggestion of 
Banks and Caudell which applies to this situation: 
If two or more species are included in the original series of specimens upon 
which a new species has been based and the author has not labeled, nor has he 
nor anyone else designated one as type, nor restricted the type material, and it 
results that one of the included species is a synonym of an older valid species .. . 
then the type is restricted to the remaining material. 
The above suggestion would at first seem to contradict my decision 
in this case. However, my interpretation is that by publishing with 
the original description data that could apply only to certain of the 
type specimens, Darlington “restricted the type material” in such a 
way that the decision made here is justified. 
Eccoptomera crypta, new species 
Fiaure 25 
The appearance of the eye readily distinguishes this species from 
Ececoptomera simplex Coquillett. The difference in eye size is accen- 
tuated by the flattened appearance of the eyein EF. simplex Coquillett, 
as compared with the convex surface of the eye in E. crypta, new 
species. There is no indication that these differences are artifacts 
resulting from changes during the drying of the specimens. 
This species is being described from male specimens only, inasmuch 
as Iam not able to separate the females of #. crypta, new species, E. 
garretti, new species, and EF. callipus Garrett. I have no females 
collected at the same time and place as males of crypta, but it is very 
likely that the female is similar to those of the other two species in 
this group. 
Maue.—Similar to EH. simplex Coquillett, except as follows: body 
yellow to dark orange; cheek-eye ratio from 0.75 to 1.0; surface of eye 
convex; thorax yellow, no vittae on mesonotum; at least 5 rows of setae 
between dorsocentral bristles; legs yellow, tarsi sometimes slightly 
darkened; anterior crossvein at or beyond middle of discal cell. 
DistriBputTion.— Washington, Idaho, California; June—October. 
Typrs.—Holotype: Moscow Mountain, Idaho, 28 Aug. 1949, L. R. 
Mewaldt. Paratypes: Pullman, Wash., 27 Sept., I. Matlock; Pullman, 
Wash., 8 Oct., 1954, G. D. Gill. The holotype has been deposited in 
the U.S. National Museum (USNM 65441) and the paratypes in the 
collection of the State College of Washington.
