"Cillia" is a misprint for "cilia," though a similar error 

 occurs twice on Plate xv in the word "cilliate." "Ptilinum" 

 is not defined, though frequently mentioned. 



Page 313, line 37: 



"Transfrontals." These are bristles unknown to me and 

 not satisfactorily figured. 



Page 314, line 22: 



"Acrosticals." Here and elsewhere this should be spelled 

 "acrostichal." 



Page 314, line 26: 



"Calypters." Even if this term be abandoned in favor of 

 "squamae" still definitions should be given of the alar and 

 thoracal pairs, as these are now known to show valuable 

 distinctive characters. The term "frenum" should also 

 be defined. 



Page 314, line 35 : 



If "postsutural" be used surely "presutural" is also ad- 

 missible. 



Page 315, line 6: 



The Hypopleura is not "between the metapleura and 

 pteropleura." Of course "peteropleura" is a misprint. 

 Mesonotum is not defined though mentioned elsewhere. 



Page 315, line 17: 



The "mesopleural row" of bristles is not always "near the 

 angle formed by the dorsopleural and mesopleural su- 

 tures," but may extend all down the back margin of the 

 mesopleura. 



Metanotum is not defined, though mentioned under meta- 

 pleura. 



Page 315, line 22: 



"Metapleura, the sides of the metanotum, a more or less 

 swollen space." This definition leaves it very doubtful 

 whether "metapleura" is a plural or singular noun ; it 

 might be either but I have always used "pleura" as singu- 

 lar and "plune" as plural. The metapleural bristles are 

 very important in the Asilidac.
