 surface with a few hairs, four on the posterior margins 

 of segments 1 to 7, two near the middle and two near 

 the lateral margins; ground color pale fawn, gradually 

 growing darker posteriorly, with dark brown lateral 

 bands which send out from their anterior half an 

 indefinite line that partially surrounds the stigmatal

One female specimen from a Great Marbled Godwit, 

 Liinosa fedoa (Pacific Grove, California). We had
