634. Eurythmia fumella Ely 

 Figure 1133 



Eurythmia fumella Ely, Proc. Ent. Soc. Washington, vol. 12, p. 

 202, 1910.— McDunnough, Check list. No. 6389, 1939. 



Probably nothing more than an aberrant form of 

 angulella; but known only from the unique female type, 

 and differing from angulella in the wider diffusion of 

 the whitish transverse lines of forewing, especially the 

 antemedial line and in the blackish suffusion over the 

 area between the lines. Bursa of female with but three 

 of the larger signa. Alar expanse, 14 mm. 



Type locality: East Eiver, Conn. (July, in USNM) . 



Food plant: Unknown. 



191. Ereheva, new genus 



Type op Genus: Pempelia quantulella Hulst. 



Characters of Eurythmia except: Male genitalia 

 without an apical process to gnathos, the arms of 

 gnathos fusing at their distal ends into the sclerotized 

 subanal plate (subscaphium) ; aedeagus not tapering, 

 expanding into a wide mouth at apex; penis unarmed 

 except for some sclerotized wrinklings; transtilla pro- 

 duced at middle into a stout, widely forked projection. 

 Female genitalia with bursa copulatrix evenly and finely 

 scobinate over entire inner surface; signa a single 

 elongate series of (5 to 14) thornlike spines; no cluster 

 of smaller spines at junction of bursa and ductus 

 bursae, except in parvulella where such spines are 

 arranged in a spiral extending into the ductus. Eighth 

 abdominal segment of male with compoimd dorso- 

 lateral scale tufts. 



The species included in this new genus are removed 

 from Eurythmia because of their radically different 

 genitalia. They are a tropical group with a couple of 

 extensions into the United States, while Eurythmia, as 

 now restricted, seems to be confined to the continental 

 United States. I suspect that, as in Eurythmia, the 

 several specific names (with the exception of parvulella) 

 represent no more than varieties of one widely dis- 

 tributed, superficially variable species; but this cannot 

 be determined from the specimens now available.

Forewing fuscous more or less dusted with white, 

 giving the wing a pale gray cloor, usually paler and 

 more contrasting on the basal area; antemedial line 

 slightly oblique, bordered outwardly by blackish fus- 

 cous; subterminal line faint with a narrow, blackish, 

 inner border; discal dots faint, but distinct and separate. 

 Hind wing dusky white, with veins perceptibly dark- 



ened and dark fuscous borders along costa and 

 outer margin. Alar expanse, 11-15 mm. 



Male genitalia as given for the genus. Female geni- 

 talia with from 10 to 14 signa. 



Type localities: Blanco County, Tex. {quantvleUa, 

 in AMNH, ex Rutgers) ; Santiago, Cuba {santiagella, in 

 USNM). 



Food plants: Opuntia (flowers), bell pepper, sor- 

 ghum. The larvae are evidently flower or seed feeders 

 in the plants attacked. 



Distribution: United States: Texas, Blanco 

 County (Aug.), Carrizo Springs (Oct.), Uvalde (June). 

 Puerto Rico: Aguirre Central (Apr.), Coamo Springs 

 (Apr.), Palmas Aba j as (near Guayama, July), Puerto 

 Real (Vieques IsL, Apr., July), San German (Apr., 

 Aug.). Virgin Islands: Kingshill (St. Croix; Mar., 

 Oct., Nov., Dec), no specific locality (Apr.). Cuba: 

 Santiago. Haiti: Port au Prince (May). 



The type of cpmntulella in the Rutgers Collection is 

 indeed a "very fraU" specimen as Hulst said. It con- 

 sists of a head, thorax, and a fragment of one forewing 

 and is a female (not a male as stated by Hulst). A 

 similar female from Blanco County, Tex. (in USNM), is 

 also labeled "type" by Hulst. The two specimens are 

 obviously conspecific. Dyar's santiagella has nothing 

 to distinguish it from Texas specimens except the 

 slightly larger size of his female type (14 mm.). The 

 male associated with it and also from Santiago is con- 

 siderably smaller (11.5 mm.). A long series of Cornell 

 specimens from Puerto Rico and the Virgin Islands 

 exhibits considerable variation in size and the distinct- 

 ness of the pale basal area of forewing and the extremes 

 of variation in the number of spines (signa) in the bursa. 

 There are no consistent genitalic or pattern differences 

 to distinguish even local races within the species, which 

 is apparently a tropical one that has extended its range 

 or been introduced into Texas. 



The only Texas specimens I have seen are those in the 

 National Museum, three males and five females. Three 

 of the females came originally from Hulst through the 

 Brooklyn and Fernald Collections. One female, from 

 Uvalde, was reared Jime 1925 by A. P. Dodd from a 

 larva feeding in the flowers of an Opuntia. The remain- 

 ing female and the three males were reared at Carrizo 

 Springs, Oct. 28, 1944, by members of the Special 

 Survey of the Division of Plant Quarantine of the U. 8. 

 Bureau of Entomology and Plant Quarantine from lar- 

 vae feeding in the ripened pods of bell pepper. The 

 sorghum record is from reared examples in the National 

 Collection from St. Croix.

Differs from quantulella only in its somewhat smaller 

 average size (10-12 mm.) and the more suffused brown-
