300 GROTE—GORTYNA AND ALLIED GENERA. [May 4, 
Xylena was lost, its type /thoxylea wandered off and was ticketed 
as Xylophasia by Stephens. ‘This is again a name bearing reference 
to the woodlike ornamentation and color, broken and pale ochrey 
yellow or reddish, something like ingrained, fresh oak wood. The 
name Xyéma was on the contrary inappropriately retained for the 
stonelike species of Lzthophane. Now, I have restored the types 
and righted this ; if I am followed it will clearly save future confu- 
sion. It is easy to change now, but, difficult or not, the change 
must be made hereafter when more painful, unless reason fly and 
lepidopterology decay. If it is objected that I here validate the 
Tentamen, I say a document endorsed by Mr. Scudder, Lord Wal- 
singham, Mr. Kirby and Dr. Dyar will, #zs¢# command assent with 
all the facts for it. It is a battle of literary knowledge, science 
against prejudice. One would think my workas to Lithophane 
could have been accepted, on the contrary it is sophisticated, the 
incorrect application of Xy/za again reverted to, changed back, 
under what excuse but to differ? Far more attention should be 
paid not to duplicate specific names in the group, entailing by this 
neglect the future certain confusion of collectors, and to give 
always the original description, which alone has scientific value and 
does not imperil the identification, and finally to avoid undue self- 
assertion in one’s work, but egreg’um cum me vicinia dicat non 
credam ?

In 1852 00 became the type of Dicyc/a Guen., aurago is referred 
by Guenée to C7¢ria, and I was free to limit this title, which else 
had no type, to the species favago, which has a clypeal thorn and 
is sud generis. 
1875. Grote, Check List, Buffalo, 11, 22: sauzalitze. 
This American species has also a thorn on the clypeus, which 
can be felt by passing a fine pin tenderly across the front, but it 
does not resemble the European species. It looks very much like 
Gortyna purpurifascia or harrist. It comes from San Francisco 
and the type is in British Museum. 
1882. Grote, ew Check List, New York, 29: sauzalite, buffalo- 
ensis. 
This second species, from the East, has also a thorn, and resem-
