10. Hydriomeiia calif orniata Pack. (Proc. Bobt. See. Nat. Hist., 

 XIIL396, 1871). 



This was a very puzzling species to me for some lime, until I received 

 a specimen from Rev. G. W. Taylor like the one I had determined as 

 <:alifortiiata. We had both come to the same conclusion independently, 

 and were the first, I believe, lo determine californiata correctly. Packard 

 did not understand californiata clearly, as he merged all sorts of forms 

 under that name later, but the figure (pi. VIII, fig. 30) is excellent, and 

 leaves no doubt as to the species. The type is not in the collection at 

 Cambridge, and must have been returned to the sender by Packard ; it 

 was probably from Jas. Behrens, This species occurs in late July, and 

 bears a slight resemblance \.q \2iX. perfracta Swett, but is only found on 

 the Pacific Coast to my knowledge. 



II. — Hydriometia lanavahraia Strecker (Lep. Rhop. Het. Suppl, 2, 

 1 1^ 1899). 



According to Dr. Dyar, this is a variety oi califor?iiata, but I do not 

 feel sure he knows californiata correctly, and until I can verify his 

 assertion I think it better to let matters stand as they are. The locality 

 would seem good for varieties, for the vicinity of Berkeley seems to be 

 their Mecca. I have nothing in my collection that answers to the 

 description, though Strecker does not give the essential points for 

 differentiating Hydriomenas. 



12. Hydriomena gleJiivoodata Swett (Can. Ent., XLI, p. 231, 1909). 



This is a peculiar, small, slender species with the slate-gray irregular 

 line, s curved. The mesial space is somewhat suffused with dark atoms, 

 and the whole insect is somewhat suffused with cinereous. It resembles 

 slightly var. nigrescens o{ autumnal is. The palpi are very slender and a 

 little longer than normal. I have never seen it from anywhere but the 

 Rocky Mts., my type being from Pike'§ Peak, 8,000 to 10,000 ft. elevation. 



13. Hydrio7nena magiiificata Taylor (Ent. News, XVII, No. 6, 1906). 



This resembles sùeciosata somewhat, differing in the moderate palpi. 

 The description is clear, and the species cannot be confounded with any 

 other. 



This completes all the species and varieties known to date of the 

 group with moderate palpi.
