Specimens examined : 105 S , Q 9 , from Lincoln, West 

 Point, Holt Co., Spring View Bridge, Dewey Lake in Cherry 

 Co., "Pine Ridge", Glen, and Monroe Canyon in Sioux Co., 

 collected during June. LaticoUis is apparently much com- 

 moner westwardly in the state. On June 26, 1911 the 

 writer found it fairly swarming on a moist sandy road side 

 in Monroe Canyon where in a few moments fifty-five speci- 

 mens were taken, and several times as many more still re- 

 mained on the sand. The following day the beetles had 

 deserted the spot and the species was not again seen during 

 the remaining ten days spent in the canyon. 



PLEUROSTICTI 



Abdominal spiracles, except the anterior ones, situated 

 in the dorsal portion of the sternites, forming rows which 

 diverge strongly; last spiracle usually visible behind the 

 elytra ; ligulae always firmly united with the mentum. 



RUTELINI 



Claws of all of the tarsi more or less unequal in size or 

 shape, the difference sometimes slight.
