Holotype——Female, Texas, U.S.N.M. No. 20039. 
The known distribution of this species extends from Quebec to Vir- 
ginia and Texas. It has been recorded in literature from Maine, Ver- 
mont, Connecticut, New York, Pennsylvania, Virginia, and Texas; 
there are also specimens in the United States National Museum from 
Maryland and the District of Columbia. I have also seen specimens 
from Abbotsford, Quebec, July 29 (G. Shewell), Canadian National 
Collection. 
This species has been reared from an unidentified leaf roller on 
Helianthus at Arendtsyille, Pa., August 20, 1927, by S. W. Frost; from 
“Botys sp.”; and from Desmia funeralis (Hiibner) at Cape Henry, 
Va., by August Busck, and at Washington, D. C., Quaintance No. 5542. 
DEJEANIOPALPUS LONGIPALPIS (Van der Wulp), new combination 
Myobia longipalpis VAN pER WULP, Biologia Centrali-Americana, Diptera, vol. 2, 
p. 138, 1890. 
Genea longipalpis (Van der Wulp) ALpRIcH, Ent. News, vol. 30, p. 214, 1924. 
Until a male can positively be referred to this species, its generic 
status must remain somewhat uncertain. I have seen only a female, 
in the United States National Museum, which was determined as this 
species by both Townsend and Aldrich. It agrees with the original 
description, so far as that goes, and, though no mention is made of 
certain essential characters, I assume that the determination is cor- 
rect. The characters, as nearly as can be judged from the female, 
are those of Dejeaniopalpus rather than of Genea. The vertex is 0.31 
the head width. My description of D. texensis will apply to this 
specimen, with the exceptions indicated in the key. 
Types.—Two females, from Chilpancingo, Guerrero, Mexico, pre- 
sumably in the British Museum (Natural History).
