148 BUUL-ETTN 132, UNITED STATES NATIONAL MUSEUM 



Paratypes. — Cat. No. 28038, U.S.N.M. Also in American Mu- 

 seum and collection Barnes. 



Type locality. — Hampton, N. H. • 



Described from male type, five male and one female paratypes 

 (female without abdomen) from the type locality (S. A. Shaw, 

 July 16 to Aug. 4). These constituted part of a miscellaneous 

 series from various eastern localities that Kearfott had under the 

 name zellenanuTn Fernald {=^nitidanu'ni Zeller not Clemens), It is 

 quite possible that this may be the true zellerianum. The pattern 

 matches very well with Zeller's figure; but the color is not right. 

 Zeller's description calls for a species with a golden brown median 

 bar on fore wing. In trepidulum this and other dark pattern mark- 

 ings are an almost uniform blackish brown. In as much as another 

 and quite different species has been generally identified as zelleria- 

 num (see p. 140) and as the actual type is not at hand for com- 

 parison I feel that it is better to risk a possible synonym than an 

 identification which, if wrong, would only add to the confusion of 

 our literature. A synonym more or less does no harm; but a mis- 

 identification is always a source of trouble.

Kearfott gave the different forms of this variable species a number 

 of manuscript names, but published no descriptions and allowed only 

 the above name {ornatana) to get into print. Some of the forms are 

 strikingly different from each other in pattern; but there are many 

 intergrading specimens and the genitalia are alike in all.
