* «JT suspect Macquart has gone too far in uniting here all the Choreelle of 
R. D.; the genus Homalomyia Bouché, which includes Fannia, Philinta, Aminta, 
and Delia of R. D., seems sufficiently characterised, though we are ignorant how 
far the singular character of the larva (long since figured by Swammerdam) extends. 
I find two species, apparently undescribed, of a group, I think, requiring to be dis- 
tinguished, viz. 
Celomyia. Abdomen g obovatum, ventre concavo toto membranaceo (absque 
plica aut linea coriacea longitudinali). Facies brevis impressa. Peristoma oblongum. 
Labium sub-elongatum (membranaceum tamen). Calyptra jam minima (ut in 
Homalomyia, division 2. Delia R. D.) Antenne, pedes, aleque Homalomyiae. 
Sp. 1. mollissima.” ( Haliday MSS.) 
+ Iam indebted to A. H. Haliday, Esq., for the sketch of the following dis- 
tribution and notes, upon the acalypterated Muscide. I have derived most of the 
generic characters from the work of Macquart, whose arrangement differs materially 
from that given below, as does also that of Fallen and other writers upon the Mus- 
cide. 
¢ “ The species with naked arista, dilated palpi, and somewhat bristly legs, form 
Nupharia R. D., e. gr. C. fraterna. Delina has the arista pubescent. Hydromyza 
(Fall. ) the tibie naked.” (Haliday MSS.)
