REVISION OF THE OECOPHORIDAE — CLARKE 81 



latter having a purplish sheen: tarsi broadly edged with fuscous. 

 Mesothoracic legs like anterior pair but without fuscous femora and 

 with more fuscous on tibiae and tarsi. Hind legs almost wholly 

 whitish ochreous except for delicate pink suffusion on tibiae and 

 fuscous tibial spurs. Abdomen ochreous with broken black lateral 

 lines beneath and suffused with fuscous above. 



Male genitalia. — Harpe elongate, narrow ; weakly sclerotized except 

 for clasper, sparsely clothed with fine hairs; clasper straight, blunt, 

 pointed, reaching about two-thirds distance across harpe. Anellus 

 longer than broad, subrectangular, moderately sclerotized; posterior 

 edge convex; lateral lobes little developed. Transtilla a narrow 

 sclerotized band with weak lateral lobes. Aedeagus moderately slen- 

 der, with sharp, upturned point. Gnathos an oval, spined knob. 

 Socii well developed hairy flaps. 



Female genitalia. — Base of lobe of ovipositor with a row of long 

 stout hairs. Ostium moderately large, round. Genital plate broad, 

 moderately sclerotized. Ductus bursae long, membranous; inception 

 of ductus seminalis near opening of ostium. Bursa copulatrix large, 

 oval, symmetrical, merging gradually with the ductus; gignum a large, 

 roughly diamond-shaped, spined, sclerotized plate. 



Alar expanse, 22-25 mm.

 paratypes as follows : Type $ , Duncan, Vancouver Island, British

In superficial appearance very much like the European arenella 

 but easily differentiated from it by the genitalia; in the male of 

 arenella the clasper is very broad and flattened, with a deep excavation 

 on the outer edge, while the clasper of fuscitemiinella is straight, 

 fingerlike ; the harpe of arenella is shorter and broader than that of 

 fusciterminella. In the female of arenella the anterior edge of the 

 genital plate is strongly convex but that of fusciterminella is much 

 less strongly so. 



The California specimens are somewhat darker than those from 

 British Columbia, but this may be due to their having been reared.
