Ceria signifera Loew, Neue Beitr., i, 18. 



Habitat. — Mexico (Lw.), Texas, Florida ! 



S . Length, 14™™. Face perpendicular, not at all excavated in outline, 

 yellow with a large yellow sagittate spot in the middle extending nar- 

 rowly to the oral margin and more narrowly above to the black that 

 surrounds the autennjie, the base of which is yellow, in its middle with 

 a narrow yellow stripe or spot ; on either side of the base of the an- 

 tennse the black extends out narrowly to the orbit; frontal triangle 

 yellow along the oyes and separated from the yellow of the face by the 

 lateral black projections 5 cheeks broadly black, with a yellow stripe 

 reaching from the orbit. Frontal process almost wholly obsolete; the 

 immediate ground upon which the anteuuse are inserted is yellow; first 

 I joint long and slender, a little shorter than the following two together, 

 brownish, yellow, darker toward the end, second joint shorter than the 

 third, black, reddish at the tip, third joint black. Occiput black, the 

 orbit dusted with white on the sides, vertex wholly yellow, extending 

 broadly outwards. Thorax black ; humeri, a spot on the sides at base 

 of suture, a distinct lateral supra-alar vittula, an elongate meso pleural, 

 andasterno-pleural spot immediately below, and nearly all the scutellum, 

 yellow. Abdomen much contracted at base of second segment, black ; 

 second, third, and fourth segments with equal yellow fasciie on the pos- 

 terior margins ; second segment yellow on the sides at the base, with an 

 oval reddish spot on the sides above, toward the base ; second segment 

 near the base with an interrupted fascia; third and fourth segments with 

 a U-shaped spot on each side, the convexity behind. Legs wholly 

 yellow. Wings brown in front, more yellowish toward the base ; third 

 vein only a little angulated, not bent into the first posterior cell. 



9 . Front black, at the base of the antennae, a spot on each side of 

 the base of the antennae near the eye, an arcuated transverse, abbre- 

 viated band above the base, and the vertex, yellow. 



One male specimen from Professor Riley's collection (Florida), and 

 three females in the Loew type collection from Texas (Boll), bearing 

 the label "signifera?" in Loew's writing. I find discrepancies in the 

 original description which make me doubt that this determination is 

 the correct one.
