Ashm. Algonquin, 111., 5-10, 12, 13, '96—151 " and " 6807 ", 

 " 6787 " and " 6785 " respectively. (3) By collecting myself 

 in Illinois — at Urbana, on greenhouse windows, seven fe- 

 males (April 30, 1910), one female (June 8, 1910); at Urbana 

 by sweeping, one female (May 26, 1910); at Pulaski along 

 the edges of a cypress swamp, May 14, 1910, one female 

 (C. A. Hart and A. A. G.); and at Centralia on windows one 

 female (August, 1909). Also a single female reared from 

 the eggs of Enchenopa binotata (Say), Chicago, Illinois, to- 

 gether with the species etichenopt^ and mounted with the co- 

 types of that species.* 



Habitat. — United States: Ohio; Illinois. (Chicago, Ur- 

 bana, Pekin, Centralia, Algonquin, Normal and Pulaski); 

 Michigan (Agricultural College). 



Type. — Type No. 13,817, United States National Museum, 

 Washington, D. C, one male in xylol-balsam (Pulaski, 111., 

 May 14, 1910). 



Cotype. — Accession No. 44,245, Illinois State Laboratory of 

 Natural History, Urbana, four females in xylol-balsam, 1 slide 

 (Urbana, 111., April 30, 1910). 



This species may be confused with hoivardii but is smaller 

 and resembles it in the wing ciliation only. It is common 

 in Illinois. 



Subsequently, I have found the following specimens : A 

 single female in the collections of the U. S. National Mu- 

 seum labelled " Ag. Coll., Mich. 356. Baker". Two fe- 

 males captured at Urbana, Illinois, by sweeping blue-grass 

 and clover, June 8, 1910 (A. A. G.). And from the Nason 

 collection, placed with a single female of striaticorne, three 

 females bearing the label " Cosmocoma maculipes Ashm. cf. 

 Algonquin, 111. 5-10, 96—151 ", and " 6810 ", " 6796 " and 

 "6788" respectively. From the collections of the Illinois 

 State Laboratory of Natural History : Four females (Acces- 

 sion No. 16,270) captured with a female of longipes at Ur- 

 bana, 111., by sweeping wheat. May 7, 1891 (Marten); one 



* This specimen differed from the others of consobrinus in having 

 the third funicle joint longer, but sHghtly shorter than the second ; 

 but I do not think it can be another species.
