September, 1898 ] 193 



This species should be very carefully compared with the European zetterstedtii, 

 Z., which my specimen, PI. I, 6 (Pter. Cal. and Or.), most strongly resembles. It is 

 possible that here again two species have been united under one name in the 

 American lists, but in any case eardui, Eiley, is undoubtedly variable. 



Platypfilia fesseradactyla, L. 

 I am unacquainted with any previous record of this species from America, but 

 am able to confirm its occurrence, having received several specimens from Loveland, 

 Colorado (W. G. Smith). Two specimens, collected by myself at Scott's Valley 

 (Lake Co., California, 17 — 19, VI, 1871), were not included in my monograph, being 

 in poor condition, but the longer series now received enables me to identify and 

 record them. 



Platyptilia ortJiocarpi, Wlsm. 



A specimen from Custer County, Colorado, sent by Professor Cockerell, might 

 easily be regarded as a variety of this species, but it differs slightly in the darker 

 ante-apical shade on the anterior lobe of the fore-wings, and in the greater obliquity 

 of the white transverse line which follows it. It was bred from Castilleia pallida 

 -\- acuminata, and probably represents a nearly allied species. 



Platyptilia modesta, Wlsm. 



Alucita helfragei, Fish. 

 I can add Arizona to the localities for these species ; they were collected many 

 years ago by the late H. K. Morrison. 



Pterophobus, Greoffr. (Wlgrn.). 

 In this genus the difficulties are perhaps greater than in others, many species 

 approacbing the European forms so closely as to be doubtfully separable ; they are, 

 moreover, variable, and possibly polyphagous. 



Pterophorus hipunctatus, Mschl. 



Pterophorus lipunctatus, Mschl., Ab. Senck. Nat. G-es.,XV, 346, 354 (1890) d). 

 Alucita bipunctatus,'W\sm., Pr. Z. Soc. Lond., 1891, 496, 542 (1892) (2). Leioptilus 

 microdactylus, Hdm., Stett. Ent. Ztg.,LVII, 9 (1896) (3). Pterophorus lipunctatus, 

 Wlsm., Pr. Z. Soc. Lond., 1897, 61, No. 15 (4). 



Hab. : United States— Florida (4) ; "West Indies— Portorico, i. 2, 4 ; St. 

 Croix, 4 ; St. Thomas, 3, 4 ; Grenada, 4. 



Fernald omits this West Indian species, which I recorded from Florida (Mor- 

 rison), I. c, No. 4. 



Pterophorus liomodactylus, Wkr. 



Fernald adds, " ? Leioptilus hololeucos, Z." 



Zeller's types are before me together witli better specimens, also from Chile, in 

 all of these four spots can be distinguished on the anterior lobe (two costal, followed 

 by one dorsal and one apical), there are also two on the posterior lobe (one dorsal 

 and one apical) ; even in bred specimens of homodactylus, Wkr., there is no trace of 

 any similar pattern of spots on the first lobe. The two species are decidedly 

 distinct. 



Pterophorus suhochrnceus, Wlsiri. 



Fernald adds, " ? Pterophorus lacteodactylns, Chauib."
