Ecological and Behavior Notes 53 



specimen of this large longicom was taken at the lights 

 on August 11, 1910. It was kept in confinement for some 

 time, and fed on soft peach and apple, often being found 

 with its head buried in these fruits. It lived for 20 days. 



Elaphidion villoswm Fabr. [H. S. Barber]. While 

 opening up some sumac stems in quest of wasps on Feb- 

 ruary 12, 1919, I found an adult beetle in the stem, still 

 moist and soft, and a fresh shedding-skin near by; this 

 condition indicated that emergence had just taken place. 

 The most interesting feature was that a plug was just 

 above the chamber and about two inches from the aper- 

 ture at the top of the stalk. This plug was about one- 

 fourth inch in length, and was made not of the pith of the 

 sumac, but of the tough, woody threads, tightly curled 

 and matted together, making a very compact plug. 



Liopus alpha Say. [E. A. Schwarz]. Taken alive in 

 a hollow elder stem. May 15, 1918, and emerged from a 

 sumac twig on May 31, 1920. 



Liopus variegatus Hald. [H. S. Barber]. The pupa of 

 this beetle was taken from under the bark of a dead tree 

 at Meramec Highlands on May 11, 1916. On May 17 it 

 became adult, and lived in the jar, containing dead bark, 

 for twelve days. 



Saperda tridentata Oliv. [H. S. Barber]. Several 

 larvae and pupae and a few adults of this beetle were 

 found under the loose bark of rotting logs on May 7 

 and 11, 1916. 



Gastroidea cyanea Melsh. [E. A, Schwarz] x Coccinella 

 9-notata [E. A. Schwarz]. A 5 of C 9-notata and a <^ 

 G. cyanea were in actual copulo when kept in confine- 

 ment on April 29, 1914. This same condition had been 

 noted in the open field a few days previously. 



Melasoma scriptum Fab. [E. A. Schwarz] x Melasoma 

 interruptum Fab. [E. A. Schwarz]. These two distinct 

 species of Chrysilomeda were actually seen in copulo on 

 May 5, 1915 on a willow. Later the female laid eggs in 

 confinement which hatched.
