by Schmiedeknecht, in the collection of the iNIassachiuietts 

 Agricultural College, and I have compared them carefully with 

 specimens of fernaldcs and tricolor, and I find from this com- 

 parison that both qnadricolor and globosiis, especially the 

 former, are closely allied to both fernaldce and tricolor. 

 While I was unable to dissect any of these specimens of 

 either qnadricolor or globosus, on account of their value as 

 authentic specimens, the genitalia of one of the qnadricolor 

 males were protruding from the end of the abdomen, and I 

 was thus enabled to compare even the genitalia of this species 

 with those of tricolor, and they are very similar, as Schmie- 

 deknecht's figure shows. While qnadricolor and globosiis 

 both differ noticeably, in some respects, in coloration from 

 {ernaldcE and tricolor, they all agree in a tendency to have 

 some reddish pile on the apical portion of the abdomen. 



I am pleased to name this species in honer of Mrs. C. H. 

 Fernald.
