"reared elm sect.," A. P. Jacot (USNM); Galveston, Tex., Sept. 21, 

 1956, A. B. Beavers (USNM); Kearney, Arlington Co., Va., Oct. 2, 

 1912, F. Johanson (USNM); East Lansing, Mich., July 9, 1940, 

 Sabrosky (author's collection); Nyack, N. Y., May 18-20, 1936, 

 "from elm" (AMNH) ; Maynooth, Ontario, Sept. 5, 1953, and Ottawa, 

 Ontario, May 29, 1955, both J. F. McAlpine (CDA). Four specimens 

 from Westbury, Long Island, N. Y., A. B. Champlain, are probably 

 the basis for the record of Odinia maculata published in "Insects of 

 New York" (1928, p. 865). 



The rearing records are not conclusive as to the feeding habits of 

 the odiniid larvae, other than that they are associated with insect 

 damage in trees. Most of the studies on forest insects referred to 

 above recorded the flies as reared during studies of various beetles 

 (Scolytus, Saperda, etc.) reared from dead or dying Hicoria. In one 

 case (Westbury, N. Y.), the dipterous larvae and pupae were found 

 in the primary egg galleries of Scolytus qvudrispinosus Say, in Hicoria. 

 Several specimens from Hendersonville, N. C, were reared from 

 maggots found in a tulip tree in which the outer bark was infested 

 with larvae of the phycitid Euzophera ostricolorella Hulst. The 

 Ottawa example was labeled "on bleeding elm stump." Collin (1952) 

 noted that in Europe meijerei "is to be found on diseased elm trees." 



6. Odinia picta (Loew) 



Milichia picta Loew, 1861, Berliner Ent. Zeitschr., vol. 5, p. 358 (Cent. 1, no. 99) 

 (Georgia). 



This species is adequately characterized in the key. It is unique 

 in the genus in having a reticulated wing pattern. The brown areas 

 are not definite spots surrounded by a whitish corona as in the Neo- 

 tropical species williamsi, coronata, and parvipunctata. Unlike those 

 species also, the face is yellow and the second antennal segment 

 dorsally is not whitish and compressed. 



I have seen only two specimens (MCZ) — the holotype, and a male 

 from Montgomery Co., Pa., June 2, 1895, C. W. Johnson. The 

 Pennsylvania specimen is apparently the one recorded as picta by 

 Johnson (1910, Psyche, vol. 17, p. 235). 



7. Odinia williamsi Johnson 



Odinia williamsi Johnson, 1924, Zoologica, vol. 5, p. 90 (Galdpagos Islands). —
