A REVIEW OF THE AMERICAN SPECIES OF THE GENUS 

 PALLOPTERA. 



By Charles W. Johnson, 

 P)Oston Society of Natural History, Boston, ]\Iass. 



In a recent study of the species of Palloptera, including the 

 type of P. jucunda Loew, in the Museum of Comparative Zoology, 

 it seemed that some discrepancies existed that should be corrected. 

 Prior to Dr. A. L. Melander's paper^ no figures accompanied the 

 original descriptions, and this may account for some of the errors. 

 A comparison of the figure of the wing of F. jucunda by Melander 

 with the type shows a marked difference (although the series of 

 P. jucunda shows some variation) and is apt to be misleading, 

 especially since there is a much larger species having practically 

 the same wing pattern as that figured for P. jucunda. The wing 

 figured as P. jucunda in Williston's Manual of North American 

 Diptera, 3d edition, page 80, is P. siiperha. I have been unable 

 to find an American species agreeing with the European P. arcuata 

 Meig. It was determined by Coquillett and recorded from Mt. 

 Washington, N. H., by Mrs. Annie T. Slosson, but none of the 

 specimens I have collected there and at Mt. Desert, Me., agi-ee 

 with that species. Submitting a sketch of the wing of a specimen 

 taken at Base Station, Mt. Washington, to Mrs. Slossom, she writes : 

 "I have looked up the unique specimen of P. arcuata. It is in 

 poor condition, abdomen missing, but wings perfect. They are 

 exactly lilve your figure, clouded at the tip, not extending along 

 the costa."
