78 U.S. NATIONAL MUSEUM BULLETIN 255 



lectotype designation is possible. Very likely a few of the syntypes 

 stni exist as unlabelled material in the collections of the U.S. National 

 Museum. Even though it is possible that no type material of Prodoxus 

 decipiens was available for examination, the status of the name as a 

 synonym of P. quinquepunctellus seems unquestionable. 



It was early noted by RUey (1892a) that all eastern specimens of 

 P. quinquepunctellus were immaculate, whereas the western forms, 

 especially those from Colorado and Texas, were sometimes spotted. 

 The present author like\vise has noted the absence of maculate speci- 

 mens east of the Mississippi River. In addition to Texas and Colo- 

 rado, I have also noted the spotted form from Arizona, New Mexico, 

 North Dakota, and Utah. This variation probably has little signifi- 

 cance as both maculate and immaculate individuals can be observed 

 within the same flower. It is possible that both kinds of individuals 

 may appear within a given brood.
