Eccoptomera garretti, new species 
Figure 26 
When working over the genus Eccoptomera I found, on the basis of 
general appearance, five groups. A detailed study of cheek-eye ratio, 
chaetotaxy, and male terminalia verified four of these groups, which 
were then given tentative species designations and subsequently 
matched with types of described species. ‘The male terminalia of the 
fifth group showed one form to be very distinct from all others; this 
was LE. callipus Garrett. The remaining specimens in the group were 
practically identical, except that there appeared to be two distinct 
shapes to the epiphallic processes, and to a lesser degree, two shapes 
to the posterior surstyli. Both forms must be described as new. The 
epiphallic process is gradually tapered toward the distal end in £. 
garretti, new species, whereas in EH. crypta, new species, this structure 
is bluntly rounded distally and not tapered to a narrow tip. The 
surstylus appears to be more narrowed distally in E. crypta, new 
species. 
The description of /. garretti, new species, then, is the same as for 
E. crypta, new species, except for the differences noted above. The 
cheek-eye ratio of specimens thus far examined is from 0.65 to 0.78. 
The females of the type series are similar to the males, except for the 
terminalia. 
Typrs.—Holotype male, allotype, 4 male paratypes and 2 female 
paratypes, Santa Cruz, Calif., 1-2 June 1919, M. C. Van Duzee; all 
specimens sent on loan from the California Academy of Sciences. The 
holotype, allotype, 2 male paratypes, and 1 female paratype have been 
deposited in the California Academy of Sciences, 1 paratype of each 
sex in the collection of the U.S. National Museum, and 1 male para- 
type in the collection of the State College of Washington. 
In addition to the type series, I have examined a male specimen 
from Soquel, Calif., 18-20 June 1950, M. T. James (in the collection 
of the State College of Washington). 
Eccoptomera callipus Garrett 
Figure 29 
Eccoptomera callipus Garrett, 1925a, p. 2.—Czerny, 1930, p. 442. 
This species resembles the preceding two species, but the unique 
appearance of the male terminalia will readily distinguish it. I have 
examined the types in the Garrett collection. 
Ma.e.—Similar to preceding two species except as follows: cheek- 
eye ratio from 0.85 to 1.0; a distinct flattened knoblike protrusion
