SYNOPSIS OF NORTH AMERICAN SYRPHID^. 299 



coidalzelle ziemlich laug; die Eadialzelle [marginal cell] ofteu. Typ- 

 ische Art: Salpingog aster pygophora Schiner." — South America (14 to 

 15mm jjj length). 



Doros insularis, Annales, 18ci3, 330. — Cuba. 



Whether this is a true Doros {i. e., differing from Xanthogramma in 

 the abdomen being clubbed, or the basal segments narrow) or not, can- 

 not be made out from the description. 



Eristalis opulentus, Annales, 1883, 336. — Cuba. 



The species here described appears to be closely allied to those placed 

 under Pteroptila [Plagiocera). 



Sphi^ea fulvifrons, Annales, 1883, 341. — Georgia. 



Notwithstanding the discrepancies in the description, there can be 

 little or no doubt but that this is the widespread, common, and easily 

 recognized Milesia ornata. 



Lepidomyia cincta, Annales, 1883, 345. — Mexico. 



To what genus this belongs I cannot say. The author was in uncer- 

 tainty about Lepidomyia, for which he had grounds, as Loew's very 

 brief diagnosis does not convey a very good idea of the genus. Bigot's 

 species is, however, evidently no Lepromyia. The pilosity of the eyes 

 and the light color of the scutellum indicate that it belongs somewhere 

 in the vicinity of Chilosia. 



Asemosyrphus oculiferus, Annales, 1883, 350. — Mexico, California. 

 Asemosyrphus nigroscutatus, Annales, 1883, 351. — Mexico. 



The latter species the author separated on unimportant differences, 

 and thought might be only a variety of A. oculiferus, a view in which I 

 concur. They are both synonyms of HelopMlus Mexicanus, which will 

 be readily enough seen by comparing the description with male, not 

 female, specimens. 



Asemosyrphus flavicandatus, Annales, 1883, 351. — Mexico. 

 Asemosyrphus bicolor, Annales, 1883, 350. — Mexico. 



Whether these species belong to a genus distinct from HelopMlus or 

 not 1 cannot say. 



Calliprobola aerea, Annales, 1883, 352. — Washington Territory. 

 Is a synonym oi Brachypalpus {Calliprobola) pulcher. 

 Calliprob61a calorhina, Annales, 1883, 353. — Washington Territory, 



There is scarcely any doubt but that this is the same as Sphecotnyia 

 Pattoni. It has scarcely anything in common with the preceding spe- 

 cies. 



Calliprobola pictipes, Annales, 1883, 354. — Carolina. 



See GriorMna pictipes above. 

 Brachypalpus Morrisoni, Annales, 1883, 355. — Washington Territory. 



This is my Pocota grandis, described first as Eadromyia grandis. 

 The author may be right in locating it under Brachypalpus, but the
