NORTH AMERICAN GEOTRUPINAE — HOWDEN 223 



this is a winter species, perhaps comparable to darlingtoni in habits, 

 but further information is badly needed. 

 Specimens examined: 4 males, 2 females.

Bolboceras simi (Wallis) 



Odontaeus simi Wallis, 1928, p. 170. Type, male, Merchantville, N. J., July 27,

The following excerpt from Sim (1930, p. 145) presents all the 

 biological information available on the species : 



The type locality for the present species is the golf course at Merchantville, 

 N. J. This seems to be a characteristic habitat. Throughout July and August 

 the little beetles give evidence of their presence on green and fairway by pushing 

 up small but conspicuous piles of sand . . . Simi has been found, also, associated 

 with darlingtoni at Rancocas Park, in a pine-oak bush lot near Riverside and 

 associated with liebecki on Arney's Mount. 



Wallis (1928, p. 122) mentioned, quoting from correspondence with 

 Sim, that the species was found in the open and was not present in fall, 

 winter, or spring. Sim concluded that the beetles' actions were 

 apparently the same as darlingtoni in burrowing habits and biology. 



Sim collected two third-stage larvae with associated adults in 

 September 1927 at Riverside, N. J. One larva pupated on Nov. 10, 

 1927. Subsequently, the larva was carefully described by Ritcher 

 (1947, p. 13). Included here for purpose of identification are a few 

 of the characteristics of simi mentioned by Ritcher. 



Anterior frontal setae absent. Hypopharynx symmetrical; glossa 

 not emarginate. Tormae of epipharynx united mesally; almost sym- 

 metrical, having a large posterior epitorma and a smaller anterior one. 

 Pternotorma absent. Pedium surrounded by a fairly uniform arc of 

 phobae and covered with spicules. 



Specimens examined: 27 males, 19 females.
