BEETLE GENUS ONTHOPHAGUS — HOWDEN, CARTWRIGHT 75 



short, stubby, quadridentate, not bent in apical half, and lacking the 

 pencil of hairs often present near the tibial spine in the male majors. 



Type. — Of subaeneus: Unknown to us. Of crihricollis Horn: Lecto- 

 type, present designation, labelled "Tex," in the Philadelphia Academy 

 of Natural Sciences, Type 3571. The lectotype is an extremely small 

 brownish castaneous specimen with a faint greenish lustre. Length 

 3J2 rnm. The USNiM collection contains a specimen from Plummers 

 Id., Alaryland, which duplicates the size and color of the lectotype. 



Type locality. — Of subaeneus: United States. Of cribricollis: 

 Texas. 



Specimens examined. — 261.

Remarks. — This small iridescent species, never commonly collected 

 but having an extended range, can be distinguished from other North 

 American Onthophagus by its broadly emarginate bidentate clypeus, 

 its completely margined pronotum which is conspicuously punctate, 

 the long, whitish setae present dorsally and ventrally, the small, 

 median conical protuberance near the anterior pronotal margin in 

 male majors, and by the carinae of the head in male minors and 

 females. 



Brown (1926) found 0. subaeneus (cribricollis) in moist woodlands 

 and postulated that the species might feed on decaying organic matter 

 on the floor of woodlands. It was collected by sifting debris from the 

 ground in a moist woods. It has been taken frequently in early 

 spring (February) at Florence, S. C, in sifting woods trash for hiber- 

 nating boll weevils. It has also been taken at fungi, at camon, under 

 the dung of various animals, and even "under chicken manm'e." 

 Some specimens have been taken in malt or malt and propionic acid 

 traps. 



The most comprehensive study of subaeneus (cribricollis) was done 

 in New Jersey by Sim (1930, p. 141) who stated: 



My own records began with June 25, 1926, when one was found under a rabbit 

 pellet in the small pine Barren at Rancocas Park, five miles from Mount Holly.
