THE GEOMETRID GENUS RACHEOSPILA. 



BV HARRISON G. DYAR, WASHINGTON, D. C. 



Our species of this genus are badly arranged in our list. The 

 synonymy is due to Hulst's observations on the collections of the British 

 Museum and other foreign collections, published by him in Entomological 

 News, VI, 71, 1895. His examination must have been very hasty, for he 

 has obviously confused several good species under the synonymy oiiixaria. 

 According to his arrangement (see Bull. 52, U. S. N. M., p. 300) we have 

 five species : iixaria, Guenee, with five synonyms ; jaspidiaria, Hulst ; 

 Hollandaria, Hulst ; viridipurpurea, Hulst, and saliusaria, Hulst, Of 

 lixa?'ia, Guenee, only rubrolineata, Packard, appears to be a true 

 synonym ; inclusaria, Walker, represents a distinct form with larger 

 dark discal dots and strongly-developed red line in the fringe, to which 

 extremaria, Walker, may be cited as a synonym if we desire to retain the 

 name, proposed as it was for specimens without locality ; cofigruata, 

 Walker, is evidently a synonym of sitellaria, Guene'e (Spec. Gen., IX, 

 374, 1857), a species quite distinct from iixa?'ia, to which also belongs 

 Synchlora Hulstiana, Dyar, described 2s a variety of 6'. Louisa, Hulst ; 

 finally, nipidenaria, Grote, is a good species, afterward redescribed as 

 Synchlora Louisa by Hulst. The three following species, Jaspidiaria, 

 Holla7idaria and viridipurpurea are all varieties of one species, which 

 is the same as Geomet7'a centi'ifugaria, Herrich-Scha^ffer, and protractaria, 

 Herrich-Schseffer (Corr.-Blatt. Zool.-Min. Verein Regensburg, 1870, 182), 

 a Cuban species. The last species, saliusaria, Hulst, is the same as 

 Eucrostis niveociliaria, Herrich-Sch8efl;er, also from Cuba. 



Our green Geometridse are more widely distributed in regard to their 

 specific forms than many other groups, and all our Southern Florida 

 species come from Cuba. I would arrange our species oi Racheospila as 

 follows : 



1. lixaria, Guenee. 4. cupidenaria, Grote. 



rubj'olineata, Packard. Louisa, Hulst. 



2. inclusaria. Walker. 5. centrifugaria, Herr.-Sch. 



extremaria. Walker (?) protractaria, Herr.-Sch. 





sitellaria, Guenee. Holla?idaria, Hulst. 



congruata, Walker. jaspidiaria, Hulst. 



tjideclararia, Walker. viridipurpurea, Hulst. 



Hulstiauas Dyar. 6. niveociliaria, Herr.-Sch. 



saltusaria. Hulst.
