ADDITIONS AND CORRECTIONS. 221 



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

 species from Brazil. (Loew.) 



Page 94. Note to Tryp. 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, for femorse read femora. 

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

 thorax. (Loew.) 



Page 140, line 5 from top, for terminal read aniennal. (Loew.) 

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



" 144, " 15 " for knob read knobs. 



" 155, " 12 " for Philhygria read Philygria. 



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.
