ICHNEUMON-FLIES OF AMERICA I 1. METOPIINAE 101 



except apex and margins of mandible, underside of scape and pedicel, 

 underside of flagellum to near middle, lenticular mark along upper 

 margin of pronotum, vertical oval mark on front part of mesopleurum 

 next the prepectal carina, mark on subtegular ridge, narrow apex of 

 scutellum (sometimes interrupted medially), small spot at apex of 

 area dentipara, sometimes small spot on tegula, front and middle 

 legs except for base of coxae and stripe on back side of femora, irreg- 

 ular apical and dorsal marks on hind coxa, hind trochanters, hind 

 femur except for apical 0.1 to 0.4 and some apical blotches, hind tibia 

 except for narrow apex, hind tarsus but often with apex of each seg- 

 ment brownish, apical 0.6 of first tergite, lateral apical corner of 

 second tergite, subapical 0.1 of third tergite, apical 0.35 of fourth 

 tergite, apical 0.4 of fifth and sixth tergites, apical 0.2 of seventh 

 tergite, and genitalia and parts of adjacent sclerites, light yellow; 

 wings tinged with reddish brown. 



Female: Colored like the male except that the mouth parts are 

 black with some yellow on the palpi, the facial shield has a large 

 median black mark, the flagellum is fulvous except above, and the 

 apical 0.25 of the sixth tergite is yellow. 



This subspecies has basically the same color pattern as the sub- 

 species M. pollinctorius, but with the light markings pale yellow 

 rather than white, these yellow markings more extensive, especially 

 on the legs and apical half of the abdomen, and the wings subhyaline, 

 tinged with reddish brown. 



The coloration described above is considered typical. Figure 186,b 

 is from a female from Donner Pass, Calif., with unusually extensive 

 yellow markings, as follows: 



Black. Face, interantennal process, side of frons, labrum, spot on 

 mandible, parts of palpi, lenticular mark along upper edge of prono- 

 tum, vertical elliptical mark on front part of mesopleurum next pre- 

 pectal carina, small mark on subtegular ridge, apex and basolateral 

 appendage of scutellum, transverse mark on postscutellum, irregular 

 spot at apex of area dentipara, two small spots next base of middle 

 coxa, apex of front coxa, all but basal part of middle coxa, front 

 stripe, small posterior apical, and large ventral apical mark on hind 

 coxa, apical 0.7 of first tergite, lateroapical spot on second tergite, 

 subapical 0.18 of third tergite, and all of fourth, fifth, and sixth ter- 

 gites except basal 0.15 ± and area surrounding the lateral oblique 

 grooves, light yellow; legs beyond coxae light yellow except for pos- 

 terior black stripes on front and middle femora, apical 0.65 of hind 

 femur black posteriorly, apical posterior brown area on hind tibia, 

 apex of first and second segments of hind tarsus brown and all of the 

 third to fifth segments brown; wings tinged with reddish brown.
