Page 84, Tryp. Solaris; Wiedemann's and Winthem's collections possess this 

 species from Brazil. (LoEW.) 



Page 94. Note to Tnjp. comma. One of my specimens from Maryland was 

 compared by Mr. Loew with Wiedemann's original and found identical. 

 The latter is a very pale specimen. It seems, therefore, that the elon- 

 gated hyaline spot at the tip of the sixth longitudinal vein is of normal 

 occurrence in this species. 0. S. 



Page 115, line 8 from top, iorfemorse read/emora. 



" 135, " 6 from bottom, for the words in brackets put of the cinereous 

 thorax. (Losw.) 



Page 140, line 5 from top, for terminal read anlennal. (LoEW.) 

 " 142, "11 " for steel-colored read steel-blue. (LoEW.) 

 " 144, " 15 " for knob read knobs. 

 " 155, " 12 " for Philhygria read Phihjgria. 



Pages 174, 175. In figures 1-7, the third longitudinal vein is made too 

 strong. Its fork especially is very delicate, sometimes hardly visible in 

 nature, so that the difference between the wings represented on figures 

 3 and 4 (Colpodia and Epidosis}, the one with, the other without, fork, 

 is not at all so striking as appears in the wood-cuts. 0. S. 



In the Index, Autonia should be read Antonia, and removed to its proper 

 place accordingly, and Blepharoptera and Philonicus are to be added ; 

 and, on page 208, the word destructor (Cecidomyia) should be removed 

 to the left, so as to be in the same line with the other specific names.
