This species was originally described from Cuba by Loew. It has 

 not subsequently been recorded as far as I am aware. 



4. Chiroxomus needhami Johannsen 



Chironomus needhami Johannsen, Bull. 124, N. Y. State Mus., 1908, p. 278. 

 Chironomus scahPtius Johannsen {nee Schrank), Bull. 86, N. Y. State Mus., 1905, 

 p. 201. 



This species bears a close resemblance to scalcrniis Schrank, but 

 according to Johannsen's description differs particularly in the com- 

 parative proportions of the fore tibia and basal joint of fore tarsus. 

 The European form is said to have the basal joint of the fore tarsi 

 twice as long as the fore tibise, whereas needhanii has it but one and 

 three fourths as long. A female submitted as needhami by Professor 

 Johannsen has, I find upon measurement under a high magnification, 

 the proportions 25: 13. The density of the color between the two 

 spots beyond wing-middle is variable ; in some speciments it is almost 

 wanting, while in others it is very distinct, forming with the spots an 

 almost complete fascia (PI. XXXV, Fig. 3). 



I have not seen any European examples of sca^ccniis, and follow 

 Johannsen as indicated above. 



Illinois localities: Havana, April 23, 1896 (C. A. Hart) ; Urbana, 

 July 21, 1890, at light in woods (Hart and Shiga) ; same locality, at 

 lighted store windows, September 15 and October 6, 19 14 (C. A. Hart 

 and J. R. Malloch) ; Momence, July 17, 1914, at light (C. A. Hart) ; 

 Monticello, June 28, 19 14 (C. A. Hart and J. R. Malloch). 



Originally described as scalccmis by Johannsen from specimens ob- 

 tained at Ithaca, N. Y., and from Washington State. Subsequently, 

 records for Indiana and Kansas were added by Johannsen. The spe- 

 cies recorded as seahvnus from New Hampshire is very probably 

 needhami. Mr. Hart took the species at light at Niles, Mich., July 13, 

 1914. 



The early stages are undescribed.
