Exorisla iiigripulph, n. sp. — With median 

 and marginal macrochaetae, but not other- 

 wise bristly, thus differing from hinuta. 

 The abdomen is also more rounded, shining 

 black, approaching that of t/ieclarum. Palpi 

 black. Eyes not thickly hairy. Differs 

 from i/ieclayum chiefly in possessing discal 

 bristles on the abdominal segments. It is 

 intermediate between theclarum and hirsutu. 

 Size about the same, 5 or 6 mm. From 

 Illinois ( .'). Type in Univeisitv of Kansas 

 collection. 



The temperate American species of 

 Exorista which I have not yet been 

 able to examine are : E. leiicaniae 

 Kirkp., cecropiae Riley, do^-ypJiorae 

 Riley,- deilephilae O. S., and hifesta 

 Will. The others mentioned in the 

 Osten Sacken Catalogue are Walker's 

 species, and none of them has been 

 recognized. E. Jlavicauda Riley is a 

 Frontina. E. ck?ysopka?ti Towns is 

 a synonym of thedariitn. If E . dei- 

 lephilae has the hind tibiae neither 

 ciliate nor sub-ciliate, it will fall with 

 platysaniiae in the table, and may be 

 distinguished at once from that species 

 by the sides of the abdomen being 

 broadly red. E. proserpina Will., 

 Scudd. Butt. New England, 1919, con- 

 sidered as a possible variety of blanda., 

 may or may not be a good species or 

 even variety. 



The 9 specimen described b\' me on 

 page 364, 1'rans. Am. Ent. Soc, 1S91, 

 I am inclined to regard as the same 

 species, ciliata^ to which I there doubt- 

 fully referred it. It would certainly 

 seem at first that the differences de- 

 scribed were specific, but still greater
