260 Report OF THE ENTOMOLOGISTS OF THE 
little larger than the point of an ordinary pin. As seen by the 
aid of a microscope or good hand lens, it. is found to vary in 
shape from a perfect ellipse to an oval, and is not as pointed as 
the egg of the corn root worm( Dzabrotica longicornis), as shown 
by illustration of the latter as given by Dr. Forbes. They have 
the same pentagonal markings as have the eggs of the D. longi- 
cornis. ‘The eggs average 0.69 mm. long and 0.48 mm. wide. 
Larva.— The larva, or “ grub,” would be described by a farmer 
as a small white wire-worm with a dark brown head and tail; it 
being hard to tell which end is head and which is tail. In shape, 
they are nearly cylindrical, about one-thirty-second of an inch 
wide and varying from one-fourth to five-eighths of an inch in 
length. With the exception of the head, first segment back of 
the head and the anal plate, which are dark brown, the body is 
pure white. ‘The head-end can be distinguished by the fact that 
the head is only about one-half as wide as the body. ‘The anal 
plate is as wide as the body, darker colored than the head, in fact, 
nearly black at the margin. The above are the only characters 
to be seen without the aid of a hand lens. With the latter, the 
anal plate will be found to have two minute, upturned teeth on 
its posterior margin. A few scattering hairs can also be seen. 
Six small thoracic legs will be found near the head, and one pro- 
tractile proleg will be found on the ventral side of the anal plate. 
Pupa.—During part of the pupal or resting stage, the striped 
beetle is nearly pure white in color.. The peculiar shaped wing 
pads and folded legs are the most conspicuous part of its body. 
A few scattering hairs can be seen by the aid of a lens. 
PARASITES. 
Dipterous.— The dissections show that old beetles, taken during 
the latter part of July and during August and September, were 
frequently parasitized with the maggot of a tachinid fly. The eggs
