I do not know of another published reference to the beetle, except 

 the checklist inclusion of the name, and Blatchley's 1 reference to 

 the original capture by Hubbard and Schwarz. 



In August of about 1882 or 1883, a flying adult lit on Mr. 

 Schwarz's newspaper while he was reading in front of Professor 

 Riley's house (on R st., near 13th, this city), and was imme- 

 diately saved for the collection. Twenty years later (August 

 9, 1902) one alighted on my shirt while I was riding with Mr. 

 Schwarz one warm afternoon on the Cabin John Car, just out- 

 side the District. This remained unique in my experience for 

 nine years, until Mr. Snyder's larvae were identified. Mr. Charles 

 Dury writes that on August 9, 1911, one lit on his paper at dusk 

 in Cincinnati, Ohio, this being his only experience with the species. 



Mr. Snyder has found the larvae occasionally since, and has 

 kindly furnished the following locality and host-plant records. 

 The first colony found extended 2 or 3 feet below the brick side- 

 walk in the base of a chestnut telegraph pole (on 9th Street near 

 "P" Street N. W. Washington, D. C., February 3, 1911), the 

 larvae making shallow longitudinal burrows filled with fine, boring 

 dust in the porous layer between the harder layers of annual 

 growth. These burrows occurred only in the moist outer layers 

 of the wood which had reached the red stage of decay. A second 

 colony was found at East Falls Church, Virginia, March 18, 1912, 

 in the moist outer layers of a decaying chestnut log and, in the 

 jar of this material kept for rearing, a winged adult was found 

 alive on July 20, 1912. Another colony was found near the same 

 locality, on June 4, 1912, living in a chestnut stump; and a yellow 

 pine log at Natural Bridge, Kentucky, (September 6, 1912) con- 

 tained a very numerous colony of larvae in the rotting, softer parts 

 between the more resinous annual rings. 2

2 Subsequent to the presentation of this paper, the breeding cell of this 

 material disclosed on February 8, 1913, a few little, legged larvse and when 

 the rotten wood was broken up it was found that the colony was apparently 

 just coming to maturity. Several specimens of the reproductive form were 

 isolated, one of which began giving birth to young almost immediately (tail 

 first and active, but becoming quiescent for a time afterward). Another, 

 much shrunken, was with her nine young in her cell. Another cell contained 

 twenty-one young but the mother could not be found. Two others of the 

 reproductive form show the mandibles and anal armature of the unborn 

 embryos through the dorsal integument, fourteen in one, eight in the other. 

 A number of mature larva? in various stages between the still feeding, dark- 

 colored specimens (having the alimentary tract distended with food), up 

 through the slow process of preparation for moulting, into the white repro- 

 ductive form were found and isolated. Isolations of the progeny have 

 been made in the hope of ultimately getting the winged adults of both 

 sexes. It is sincerely hoped that someone will secure the missing links in 

 the life cycle and also determine the factors controlling the development
