In the U. S. National Museum are Fitch'.s types of jM>//utt'i/us and 

 contahtvnattUas^ and specimens labeled by Lord Walsino'ham (blue 

 labels No. 666, 1195, 122:2, and 1223); pauclguUdlm^ poiitetellux^ -flavi- 

 i^'itfeUnx^ and contuheiiudelhix—quercivomoneUus—ilavlvU^ 



There are besides many specimens reared from oak and from apple 

 in the insectary of the U. S. Department of Aoriculture and also 

 specimens from New York (Beutetuniiller); Missouri (Murtfeldt); 

 Georgia, from live oak (Schwarz); Kansas (Crevec(iHir); PennsA'lva- 

 nia (lleidemann); West Virginia (bred from oak); District of C\)lum- 

 bia and Maryland (Busck). I have also determined specimens from 

 New Jersey (Kearfott) and from New Mexico (Cockerell). 



As the concensus of authorities is that Hu))ner\s tio-ures represent 

 this species (the variety flavivittellus Clemens) and as additional evi- 

 dence for or against this view can not ])e forthcoming, it seems 

 rational to adopt Hiibner's name instead of continuing to use the query. 



Lord Walsingham is responsible for the entire synonymy ^ which 

 Zeller already had indicated in part, and it must stand until disproved, 

 the more so as new and careful observations b}- Mr. Slingerland, who 

 has lately treated this insect very mterestingl}^ and exhaustively, seem 

 to confirm it. But Lord Walsingham expresses a doubt, and it does 

 seem to me likely, that at least two distinct species will be idtimately 

 found to have been mixed up, one feeding on oak and one on apple. 



From the material at my command at present, however, though 

 quite large, no conclusions can be made, and I am unable to separate
