M -shaped elevation bordering posterior margin, antennal ledges each 

 with a small concavity on anterior margin, transclypeal suture incom- 

 plete; pronotum with disc rugose and pvmctate; forewings hyaline, 

 with a sclerotized area along costal margin from fork of vein R almost 

 to apex of central anteapical cell; posterior femoral setal formula 

 2:1:1:1; first posterior tarsomere with length approximately equal to 

 combined length of second and third tarsomeres. Male pygofer grad- 

 ually narrowed posteriorly, the apical portion curved abruptly dorsally 

 and ending in a slender apical process which bears two teeth at its 

 base, pygofer disc with numerovis dispersed microsetae ; plates extending 

 posteriorly as far as pygofer apex, each slender, triangular, with mesal 

 margin concave near base, with numerous evenly dispersed micro- 

 setae; style extending much farther posteriorly than apex of connective ; 

 connective Y-shaped, tlie stem about equal in length to arms and with 

 a median keel; aedeagus with shaft inflated in lateral aspect, broadly 

 rounded at apex, in ventral aspect abruptly narrowed at midlength. 



Female abdominal sternum VII with a median excision which bears 

 a median convex projection. Ground color of crown, pronotum, and 

 scutellum castaneous to black with an incomplete median stripe on 

 crown, spots before and behind the ocelli, a spindleform marking along 

 each inner eye margin, the antennal ledges, three spots bordering 

 anterior pronotal margin, five on pronotal disc, a short linear marking 

 on each humerus, three spots on basal margin of scutellum, a pair 

 behind transverse impression and the extreme apex, yellow; forewing 

 hyaline, the sclerotized portion purple, marked with a pair of orange 

 spots before bases of outer two anteapical cells and a similar spot near 

 apex of each of these cells ; face with a broad reddish-fuscous median 

 area which bears two yellow spots at apex, a large round area on 

 each side of upper portion of clypeus, continued as a wide pale line 

 across pleura, yellov/. 



Holotype male, with label "Interception/Mex. or Cuba" in USNM. 

 An additional specimen from British Honduras and one from Chiapas, 

 Mexico (IZP); one male, Vera Cruz, Mexico, December (CAS); two 

 females, Yucatan, Mexico, July (UCAL); and one male, British 

 Honduras, September (NCS) have been studied. 



This species slightly resembles E. paranceps, new species, in the 

 arrangement of the markings on the anterior dorsum, but differs in its 

 much more produced head, in its sclerotized area along the costal 

 margin of the forewing, and markedly in the male genitalia. 



Egidemia inflata is one of two species which Fowler interpreted as 

 Oncometopia speculifera (Walker) in 1899. Distant (1908b:67) correctly 

 stated that Fowler had misdetermined Walker's 0. speculifera. He
