 splenium (Curtis). Que. w. to Alaska, s. to Md., w. N. C, Colo., and n. Calif.; Eurasia. Ecology: 

 Reared or presumed to have been reared from parasites of the following- Caripeta 

 divisata Wlk., Cladara limitaria (Wlk.), C. nigroangulata (Stkr.), Dysstroma citrata 

 (L.), Eupithecia placidata Taylor, E. unicolor Hulst, Lambdina fiscellaria fiscellaria 

 (Gn.), L.f. lugubrosa (Hulst), Melanolophia imitata (Wlk.), Nepytia canosaria (Wlk.), 

 Dasychira grisefacta (Dyar)?, Leucoma salicis (L.), Malacosoma disstria (Hbn.), 

 Enargia decolor (Wlk.), and a tenthredinid. Host: Meteonis hyphantriae Riley?, 

 Zemiotes reticulatus (Mues.), Phobocampe geometrae (Ash.). 

 Mesochonis sericans Curtis, 1833. Brit. Ent., v. 10, pi. 424. "6" = 9. Described from 

 Ireland (presumably Belfast). Examination of material which the U. S. Natl. Museum 

 aquired from A. W. Stelfox leads me to believe that sericans, as illustrated by Curtis, is 

 quite probably an abnormally melanic specimen of splenium. N. syn. (uncertain). 

 Mesochonis Splenium Curtis, 1833. Brit. Ent., v. 10, pi. 424. 6. Dr. H. K. Townes informed 

 me (personal commun., 1977) that he saw notes which Dr. J. F. Perkins made in 

 studying what is now the lectotype (see Fitton, 1976) which indicated that M. strenuus 

 Holmgren is a synonym of splenium, and Dr. Townes suggested that I consult the 

 original description of splenium to see if it agreed with what Dr. Perkins had concluded. 

 Having done so, I see no reason to doubt that Dr. Perkins was correct.
