Pipuncidus. Five new American species of this genus are described by 
Loew (Berir ent. Zeitsclir. 1865) : namely, Pfuseics, p. 175, from Maryland;

vaoia. 
SyRPHIDvE. 
Rondani (Archivio Canestr. vol. iii. p. 5) gives the following table of the 
subdivision of the old genus Eristalis into three genera proposed by him, the 
characters being suited both to exotic and European forms : — 
A. Third and fourth longitudinal veins produced separately to the margin 
(wing figured, pi. 5. fig. 4) Myathropa (Rond.) 
(type E. Jlorea, Linn.). 
AA. Third and fourth longitudinal veins united at the apex before the 
margin (wing figured, pi. 5. lig. 3). 
B. Arista plumose or distinctly pilose Eristalis 
(type E, arbustorum, Lin.). 
BB. Arista nearly naked or scarcely tomentose. 
Eristalomya (Rond.) 
(type E. tenax, Lin.). 
Eristalis quadraticornis (Macq.) and testaceiscutellata (Macq.) are the sexes 
of the same species, according to Rondani, 1. c. p. 6, and E. limbatinervis 
(Macq.) is probably synonymous with E. agnata (Rond.), 1. c. p. 7. 
Rondani also gives a tabular synopsis of the three genera proposed by him 
(in 1844) to be established at the expense of the genua Milesia (Lat.), 
I, c. p. 7 : — 
A. Second and third longitudinal veins united at the apex before the 
costal (wing, pi. 5. fig. 1) Sphixea (Rond.). 
AA. Second and third longitudinal veins produced separately to the 
costal. 
B. Last posterior longitudinal vein produced from its conjunction 
with the“ penultimate parallel to the posterior margin (wing 
figured, pi. 5. fig. 2) Milesia. 
BB. Last posterior longitudinal vein passing obliquely from its con- 
junction with the preceding one to the posterior margin. 
Calliprobola (Rond.). 
Eumerus strigatus (Fall.) has been taken by Truqui near Damascus, accord- 
ing to Rondani, 1. c. p. 10.
