Might readil}' be taken for P. ferruginea, but the fuscous 

 spots on vertex, the abdominal segments bordered with black 

 on the sides and posteriorly and the formation of the inner ap- 

 pendages, easily distinguish it from the last named species. In 

 general appearance, P. beutenmucUeri resembles cingulata, but 

 this species has the flagellar segments bicolored, the costal cells 

 yellow-tinted, besides other differences. Dedicated to Mr. 

 Wm. Beutenmueller.
