(New synonymy.) 



Forewing white more or less dusted with fuscous, the 

 concentrated brown dusting appearing more or less 

 blackish to the naked eye; antemedial line transverse, 

 indicated by a dark outer border which is frequently 

 produced into a sharp, outward angle at top of cell; 

 subterminal line near and parallel to termen, bordered 

 inwardly by a dark border and outwardly by some dark 

 dusting; discal dots at end of cell small, blackish, 

 separate. Hind wing whitish, subpellucid; the veins 

 but faintly darkened; a fuscous line along termen. 

 Alar expanse, 10-15 mm. 



Male genitalia as given for the genus: Female geni- 

 talia with the larger spines and discs, comprising the 

 signa, varying from 4 to 6. The type of hospitella has 

 5. One of the paratypes of spaldingella has 4, as in 

 yavapaella (fig. 1131). The other female paratype of 

 spaldingella has 5, as has a specimen from Winter Park, 

 Fla. A female of hospitella in the National Museum 

 from Texas (fig. 1130a) shows 6. There is no corre- 

 spondence between locality or pattern variation and the 

 number of the larger signa. 



Type localities: Te.xas {hospitella, in BM); Stock- 

 ton, Utah {spaldingella, in USNM). 



Food plant: Unknown. 



Distribution: Florida, Winter Park (July); Texas, 

 Bosque County (May, July); BrownsvUle (May), Kerr- 

 ville (July); Arizona, Maricopa County, Fish Creek 

 (Sept.), Phoenix (Sept.), Liberty (Sept.); Utah, Stock- 

 ton (Aug., Sept.). 



Our series (14 specimens) under hospitella in the 

 National Collection contained two species, not dis- 

 tinguishable on superficial characters but radically dif- 

 ferent in male and female genitalia. Eight of these 

 specimens were the true hospitella. The remaining six 

 are quantulella Hulst which Ragonot (1889), Hulst 

 (1900), Hampson (1901), and later authors have treated 

 as a synonym of hospitella, but wliich, along with par- 

 vulella Ely and the tropical forms Dyar described under 

 Eurythmia, I am removing to form the new genus 

 Erelieva. From Clarke's notes I suspect that the orig- 

 inal type series of hospitella in the British Museum is 

 also a mixture. It consists of four females and two 

 males. As no one of the cotypes was designated by 

 ZeUer or any later worker as the actual holotype I am 

 here designating the female of his type series dated 

 "17-V" as lectotype. It bears the following labels: A 

 small white label with the numerals "17/5" to indicate 



date; another white, rectangular label with the inscrip- 

 tion "Bosque Co. Texas"; the usual Zeller rectangular 

 green label inscribed "hospitella Z. Texas Stt. 68"; and 

 another white label with "Zell. Coll. 1884." A sketch 

 of the genitaha of this lectotype shows five of the larger 

 signa in bursa (2 thorns and 3 discs) similar to the 

 arrangement shown in figure 1130. 



632. Eurythmia hospitella yavapaella Dyar, new status 

 Figure 1131 



Eurythmia yavapaella Dyar, Journ. New York Ent. Soc, vol. 14, 

 p. 108, 1906.— McDunnough, Check list. No. 6392, 1939. 



Forewing more heavily dusted with dark scaling than 

 in typical spaldingella; general color, to the naked eye, 

 more brownish fuscous than ash gray and with the dark 

 borders of the transverse lines more or less obscured in 

 the dark overscaling of the wing; hind wing with a faint 

 smoky tint. Alar expanse, 13.5-15.5 mm. 



Female genitalia of specimen from Glenwood Springs, 

 Colo. (fig. 1131) show fom- large signa. Another female 

 from the same locality and collection shows six of the 

 larger signa. A San Diego, Calif., female (fig. 1131a) 

 shows five. 



Type locality: Yavapai Coimty, Ariz, (type in 

 USNM). 



Food plant: Unknown. 



Distribution: Arizona, Yavapai County; Colorado, 

 Glenwood Springs; California, San Diego (May, July), 

 San Felipe Wash, San Diego Coimty (June). 



This is at most a race and probably no more than a 

 color variety of hospitella. I am holding the name 

 merely as a precaution against possible future separa- 

 tion. 



633. Eurythmia angulella Ely 

 Figure 1132 



Eurythmia angulella Ely, Proc. Ent. Soc. Washington, vol. 12, 

 p. 202, 1910.— McDunnough, Check list. No. 6387, 1939. 



Eurythmia diffusella Ely, Proc. Ent. Soc. Washington, vol. 12, 

 p. 202, 1910.— McDunnough, Check list, No. 6388, 1939. 



(New synonymy.) 



Similar to the dark western form, yavapaella, except 

 dark margins of transverse lines of forewing somewhat 

 more contrasted and hind wings darker. Bursa copu- 

 latrix of female also larger than that of any western 

 specimens. The name angulella may apply only to a 

 northeastern race of hospitella but in the absence of any 

 intergrading examples from any central United States 

 localities we must keep angulella specifically separated. 

 Ely's diffusella, represented only by his male type, is 

 simply a slightly more brownish specimen of angulella 

 with slightly wider dark margin to the antemedial line. 

 Alar expanse, 12-14 mm. 



Type locality: East River, Conn, {angulella and 

 diffusella, in USNM). 



Food plant: Unloiown. 



Represented in the National Museum by five males 

 and nine females from the type locaUty (July) and one 

 male from Trenton, Ontario, Canada (July).
