branches, 5 had 8, 8 had 9, 9 had 10. Thus in one series there 
was a predominance of 7-, 8-, and 9-branched spiracles, with only 
a few 9- and 10-branched ones; in the other series, 8-, 9-, and 
10-branched spiracles’ predominated, only a few having 7 
branches). These branches are small, short, and the length of 
the external portion is approximately equal to that of the spiracu- 
lar chamber. 
Adult. Davis (1928) gave a note upon the oviposition by 
females of this species upon a thin and emaciated kitten in 
Virginia. The eggs were deposited in the fur, particularly near 
the tail. So far as Davis could ascertain, the animal was weak 
and ill for want of food but was not wounded. McAtee (1929) 
reported that he reared this species from a nest of starlings in 
Virginia. Donohoe (1937) stated that Phaenicia caerulewiridis 
is of considerable importance in the northern part of the Sac- 
ramento Valley, Calif., in areas where the drying of certain 
fruits is carried on commercially. 
Phaemcia caerulerwiridis is a common species in the woods and 
fields, where it may sometimes be collected upon human excre- 
ment. It does not seem to be abundant about houses, but may 
be collected in large numbers in traps baited with decaying 
meats when such traps are placed in urban areas. It appears 
about May 10 each year in the vicinity of Washington, D. C.
