alli 
pears to be a rather common species with a range almost as extensive as 
that of sarracenioides. 
SarcopHaca, n. sp. (Aldrich det.) 
May 6, 1918, we received two pinned male Phyllophaga farcta from 
F. B. Paddock, which bore the label “Lometa, Texas, April 30, 1918”. 
On receipt the abdomen of one beetle was found loose in the box, to- 
gether with two sarcophagid larvae, one of which was immature and 
did not issue, the other issuing as an adult fly May 20. It was de- 
termined by Dr. Aldrich as a new species belonging, according to genital 
characters, to the group known to be parasites. 
SARCOPHAGA HELIcIs Towns. 
S. helicis has been repeatedly reared from larvae and puparia from 
cages containing numbers of May-beetles caged for parasites, and the 
dying beetles were no doubt responsible for the attraction of helicis 
adults and their subsequent oviposition in the cage through the wire 
screen. Repeated unsuccessful attempts have been made to induce the 
flies to infest live beetles, and it might be mentioned in this connection 
that Mr. A. F. Satterthwait conducted at Lafayette, Ind., a number of 
experiments to ascertain whether the flies of this species would infest 
live army-worms (Cirphis unipuncta), all these experiments resulting 
negatively. 
In 1893 Mr. C. H. T. Townsend (74) listed this species among a 
lot reared from Phyllophaga by Dr. Forbes, but there is no evidence 
that they were reared from live beetles. Dr. J. M. Aldrich (2) also 
records it as having been reared from Phyllophaga adults at Washing- 
ton, D. C., in 1895, but he questioned this record and considered it as 
probably a scavenger. The writer believes there is no basis for regarding 
S. helicis as a parasite of Phyllophaga, but there is sufficient evidence 
to prove its scavenger habits. 
SARCOPHAGA UTILIS Ald. 
We have reared S. utilis from a dead Pelidnota punctata adult, from 
loose puparia in the soil of Phyllophaga cages, and in one instance from 
a larva found in the body of a dead female P. implicita. ,The beetles 
in the cage in the last-mentioned case were collected at Lafayette, Ind., 
June 21, 1915, and the dead implicita beetle containing the nearly full- 
grown larva of S. utilis was found July 2. The larva left the beetle 
and pupated in the soil several days after, and the adult fly issued August 
12. We have also reared it from dead Cotinus nitida adults, in which 
case it was almost certainly a scavenger, and Mr. W. R. Walton reared 
it from a dead Geotrupes splendidus (2). 
The possibility of this species being parasitic on Phyllophaga is 
very much to be doubted in the face of the evidence at hand. 
SARCOPHAGA FALCULATA Pand. 
This fly was obtained by E. G. Kelly and J. S. Wade from a cage 
containing May-beetles collected at Charleston, Mo., by Vernon King,
