PSEUDOTEPHRITIS (PSEUDOTEPHRITINA) CRIBRUM (Loew) 



When Loew described this species he had some doubts as to its 

 specific distinction from cribellmn^ and he indicated that it might be 

 merely a variant, in whicii case the latter name would have priority. 



There is one specimen in the National Museum that has the char- 

 acters cited in the foregoing key and in addition has the basal pair 

 of scutellar bristles very much smaller and finer than the apical pair ; 

 and two specimens that have the same wing characters as cited and 

 the four scutellar bristles about equally long and strong. 



Though it may be proved yet that this is merely a variety of 

 cribeUum^ in the meantime the evidence at hand convinces me that 

 it is best to retain them as distinct species until rearing from known 

 parents proves to the contrary. 



Originally described from the " Middle States." Subsequently 

 recorded from New York. Specimens in National Museum are from 

 Onaga, Kans., Victoria, Tex., and Redlands, Calif.
