beetles to pupate, which is never the case with the beetle parasites already 
treated. Of the eight sarcophagids briefly treated in this connection 
only the first four (S. prohibita S. tuberosa, var. sarracentoides, S. cim- 
bicis, and S. new species) are probably true parasites of May-beetles. 
Like other sarcophagids they are active during the daytime, and each 
of the four was reared from a diurnal May-beetle. 
SARCOPHAGA PROHIBITA Ald. 
We have only one rearing record of this species. In a lot of Phyl- 
lophaga lanceolata received at Lafayette, Ind., July 4, 1916, from J. W. 
McColloch and W. P. Hayes, and collected at Manhattan, Kan., three 
days previous, one male and one female beetle were dead July 6, each 
containing a dipterous larva. One fly issued July 25, 1916, but was 
destroyed in the mail before being determined. The other fly issued 
June 5, 1917, and was determined by Dr. Aldrich as his prohibita. From 
the facts that both beetle and fly are diurnal, that the beetles were alive 
when received at Lafayette, and that prohibita is not known to occur 
in, Indiana but is more or less common in Kansas, it seems reasonably 
certain that this fly is a parasite of Phyllophaga. 
SARCOPHAGA TUBEROSA Pand., var. SARRACENIOIDES Ald. 
We have never observed this species, but Dr. J. M. Aldrich (2) 
records it on the authority of Mr. E. G. Kelly as having been reared 
from adult Phyllophaga. Mr. E. L. Barrett, of.the U. S. Entomological 
Laboratory at Wellington, Kan., obtained a number of this species July 
13, 1916, from a screen-covered cage containing adult Phyllophaga 
lanceolata collected June 9, 1916. The cage had been sifted July 10, at 
which time the puparia of this fly were found in the dirt. It is probable 
that this sarcophagid is a true parasite of the diurnal lanceolata, but it is 
evident from our present knowledge of the Sarcophagidae that it is 
possible for the flies to deposit their larvae through the wire screen, and 
this is especially likely when the cages contain large numbers of beetles, 
many of which die on the surface, the dead bodies together with the 
abundant excreta being attractive to female sarcophagids. This fly has 
been recorded as parasitic on several insects and has also been reared 
from human excrement, dead fish, etc. Its range is from Virginia to 
Washington and British Columbia on the west, and south to Texas and 
Arizona. 
SARCOPHAGA CIMBICIS Towns. 
This species was obtained from a screen cage containing Phylloph- 
aga lanceolata by Mr. E. L. Barrett at Wellington, Kan., and was 
reared along with S. twberosa var. sarracenioides, notes for which have 
just been given under that species heading. It is probably a true parasite 
of this diurnal May-beetle, but further exact experiments will be neces- 
sary to prove this beyond doubt. The species was originally reared from 
the willow sawfly (Cimbex americana), and no further records of its 
parasitic habits have been published to my knowledge, although it ap-
