NORTH AMERICAN GEOTRUPINAE — ^HOWDEN 203 



at Raleigh, N. C, digging vertical burrows 6 to 10 inches deep in the 

 hard clay soil of an old pasture during August. No data was obtained 

 on adult or larval food and no larvae were collected. 



The larva of E. lazarus lazarus has been described by Ritcher (1947, 

 pp. 10, 11) from one third-stage larva and two third instar exuviae 

 associated with the adults, all collected near Fayetteville, Ark. 



Characteristics given by Ritcher (1947, p. 10) which may be useful 

 in separating lazarus lazarus from the subsequent form are: "Frons 

 on each side with a pair of posterior frontal setae, a single exterior 

 frontal seta . . . Hypopharynx with 2 symmetrical bulbous oncyli 

 covered with cilia." 



The following additional structural characteristics may prove useful: 

 Glossa not constricted behind the base of the palpi; glossal setae 

 limited to the lateral portions near the base of the palpi.
