niidille of tlio baud is a dark line nearly parallel with tbe inner one, dilatinj;' ou tlie veins and all 

 the lines forming- distinct dark eostal spots. The outer third of the wiii.n- gray, witli dark scales 

 and with an irregular blackish wavy line, much as in ridenda and iiipta. Ilind wings wliitisli, 

 with no lines, and with three dark dots on the frnige of the internal angle. The outer third of 

 the wing faintly dusted more or less with flue dark scales. Wings pale whitish beneath; two 

 blackish costal spots beyond the middle, and costa of both wings speckled with dark scales. A 

 faint difluse baud passes across the hind wings just beyond the middle, and the margin of both 

 wings is speckled with dark scales. Body beneath pale, aijd the legs (tarsi) ringed with dark 

 scales. 



After preparing the preceding descriptions I fiud that ^Ir. Edwaids adds to his description 

 of G./onnasd the following remark: 



It is possible that (I. ridcrida ami G. rnpta are forms of oue species, ami that (i. alhnfascia and G. formosa are 

 forms of another, but I prefer to cousider tbem as distinct until future investigation shall determine their trufr 

 Ijosition. 



Mr. Dyar tells me that he has a specimen of G. formosa from El Paso, Tex. Professor French 

 reports it from Utah. G. var. ridenda occurred at Fort Collins, Colo., May 'So, June 11, and at 

 Denver July 2.5 (C. P. Gillette). 



Section 11 (Eumdia Neum.). 



This section corresponds to the genus {file) Mvlia or EuihcVki of ^Messrs. Nenmoegeu and Dyar. 

 At first, with only a single specimen of var. slonsoniw to judge by, I thought it was the type; of a 

 distiuct genus, as the head, antenna', palpi, and venation seemed so different, but after careful 

 and repeated examinations of si^ecimens, labeled (ivimacuhi, lintneri, wrU/htii, and severa, and 

 observing the general identity of form of body, wings, and especially of markings, as well as 

 the larval characters. Dr. Dyar stating that the larva of the Californian sercra does not 

 differ generally from that of E. trilineata, I think with our present knowledge it would be quite 

 unnecessary to recognize Eumelia as a distinct genus. 



The structural differences between G. trilineala and G. severa, var. slossoiiiw, and which at 

 first led me to think them generically distinct, are the following: 



A 9 . The head is remarkably small, much more so than in G. trilineatit, and is loosely scaled 

 in front. The antenna' are pectinated, the branches a little longer than in 9 triliueafa. The palpi 

 are short, small, depressed, with loose scales; and they are not quite so large and long as in 

 trilineata. The thorax differs from that of Gluplmia trilineuta in having a median dorsal tuft^ 

 The legs are hairy, and much as in trilineata, the tarsi being ringed with gray and darker scales.- 

 The fore wings are narrow, but with the cost.a unixsually convex, much more so than in trilineata; 

 the apex is somewhat rounded, but much as in trilineata; the outer edge is very faintly excavated 

 below the apex. The hind wings are of the same shape as in trilineata. There are six branches 

 of the subcostal vein; branch 1 is longer than in trilineata and ends half way between the end of 

 costal vein and end of branch 2 of the subcostal; the costal area is wider toward apex than in 

 trilineata. The fifth and sixth branches are nearly as in trilineata. The lower discal vein is not 

 so much bent as in the last-named species. The three cubital veins are nearly as in trilineata, 

 but the .second median space is wider than in that genus. The submedian vein ( V ) is represented by 

 a simple fold. In the hind wings the two branches of the subcostal are much longer than in 

 trilineata, the space between them long and narrow, in trilineata short and broad triangular. 

 The discal veins are, taken together, slightly curved, where in trilineata they make a decided 

 angle at the origin of the indei)endeut vein; and there is a common origin of the lower discal and 

 of the two median veinlets. The second median interspace is much wider than in the species of 

 the other section of the genus. Vein VI is represented by a simple fold.
