168 Psyche [December 



Head: rostum and palpi dark brown; antenna?, first segment large, cylindrical, 

 brown; remainder of antennae black with black hairs. Front wide, the frontal 

 tubercle not prominent; front, vertex and occiput, medium brown densely clothed 

 with long pale hairs; a spot on the front just behind the base of the antennae, paler, 

 golden-yellow. 



Thorax: mesonotal prsescutum dark dull black without apparent stripes (though 

 these may have been destroyed by some means or another), the entire sclerite 

 densely clothed with elongated white hairs, very conspicuous ; those on the dorsum 

 darker and shorter, those on the lateral margin of the sclerite exceedingly conspicu- 

 ous; scutum dull black; scutellum dark brown, also wdth numerous pale hairs; 

 post-notum black. Pleurse light grey with dense white hairs; the light color of 

 the pleurse renders it probable that the dorsum is grey with darker stripes, in living 

 material. Halteres, stem light brown, knob darker brown. Legs: coxae brown, 

 with a grey bloom; trochanter brown; fore femora, basal half brownish-yellow; 

 apical half dark brown, uniform throughout; tibia and tarsi dark brown; middle 

 leg, femora with rather more than the basal half light-colored; hind leg, femora 

 with only the extreme base yellowish. 



Wings: subhyaline or light bro^\Ti, more brownish near the veins; cells C and 

 Sc brownish-yellow; stigma small, oval; veins brown. Venation: (See fig. 6); 

 Sc extending beyond the fork of R2+3; R long, cross-vein r about one-half as long 

 as that portion of Ri beyond it; r before the middle of R2; cell Mi present. Vena- 

 tion almost exactly like the eastern E. brachycera O. S. 



Abdomen: tergum uniform dark browTi, the lateral margin pale yellowish, and 

 provided with long pale hairs, these longest on the basal segments; hypopygium 

 yellowish-orange; sternum more greyish. 



Holotype: The labels read '22 California. No. 84G. Coll. Hy. Edwards.' Prob- 

 ably from Marin Co. 



Related to E. brachycera O. S. but darker and clothed with long 

 pale hairs much longer than in brachycera. The basal segments 

 of the antennae in brachycera are very light yellowish-red, not 

 brown; the front of brachycera in the vicinity of the tubercle is 

 uniformly pale; the thoracic dorsum may or may not be simi- 

 larly colored in the two species (see statement, above, concerning 

 the condition of the thorax in albihirfa). In brachycera the legs 

 are much lighter-colored with narrow blackish tips to all the femora; 

 in albihirta the femoral tips are uniform brown and very broad. 



Eriocera fultonensis sp. nov. 



Antenuje short in both sexes; cell Mi absent; body coloration dark brown; 

 prsescutum four-striped; wings light brown; cross-vein r far before the fork of 

 Rj+s. 



cf. Length, 9.6-10.2 mm.; wing, 9-10.4 mm. 



9, Length, 11.2-11.5 mm.; wing, 10.5-11.3 mm.
