“Fire Flies.” 
Soft bodied insects, many of which do not resemble beetles very 
closely. They rest during the day, but in the evening become 
active and fly about. The luminous species giving off their bril- 
liant light. The life history of even many of the common species 
is unknown. Dr. Le Conte published a synopsis of N. A. species 
in Trans., 1881, vol. Ix, pp. 15-72. Since then, Dr. Horn has 
published a paper on Zaripus. Trans., 1885, vol. x11, p. 148. Our 
species are: 
LYCOSTOMUS.
