wood, Calif., and three males, July 6, 1929, Laguna, Calif. (R. H.

Apaulina cuprina, new species 
The male of cuprina is similar to the male of metallica in color- 
ing and in the genitalia, but it differs from that species, by hav- 
ing the squamal lobes infuscate, and in head proportions. The 
female of cuprina has the fourth abdominal segment similar to 
that of metallica except that it is highly polished. 
Male. Head height 10.3; length at antenna and at vibrissa 
6.8; eye height 8.3; front at narrowest 0.06 head width, 0.15 at 
vertex and 0.30 at lunule; head width 13.8; parafaciale opposite 
lunule and distance between vibrissae in the proportion 1.5:2.2; 
parafaciale and parafrontale black, with thin gray (sometimes 
brassy) pollen; coloration and chaetotaxy as in metallica, but 
the squamal lobes infuscate, the rims strongly so. Genital seg- 
ments with internal features as in metallica. 
Female. Head height 9.1; length at antenna 6.8 and at vi- 
brissa 6.4; eye height 7.5; front at narrowest (at vertex) 0.26 
head width, 0.37 at lunule; head width 12.9; width of parafaciale 
opposite lunule and distance between vibrissae in the proportion 
1.8:1.9; middle femur with two or three (more often two) an- 
teroventral bristles toward base; body color and chaetotaxy as 
in metallica but the third abdominal segment often, and the 
fourth segment always, highly polished, and the squamal lobes 
are tinged with yellow or orange. Otherwise as in male except 
for normal sexual differences. 
Length. 6-9 mm. 
Type. Male, No. 54930, U. S. National Museum. 
Type locality. Riverside, Calif. 
The type series consists of the following 23 male and 35 fe- 
male specimens: 28 females and 17 males, reared from House 
Finch, Goldfinch, and Phoebe nests, May and June, 1936, River- 
side, Calif. (A. J. Basinger); 5 males and 3 females from the 
nest of a wild canary, June 1935, Ravalli County ,Mont. (W. L. 
Jellison) ; 1 male, Mt. Moscow, Idaho, July 1, 1932, (J. M. Al.

(O. E. Plath); 1 female, Mt. Hood, Ore., July 29, 1921, (A. L. 
Melander) ; 1 female, Marys Peak, Oregon (A. L. Lovett). 
This species has usually been determined as splendida or 
metallica, especially in western states. Part of the series of 
specimens upon which Plath (1919) reported are this species. It
