DESCRIPTIVE. 



Signiphora Jlavo-palliatus , n. sp. — Length 0.02 of an inch. Robust, polished; 

 head bluish-black, much wider than thorax, three ocelli, black, two raised curved 

 lines, one on each side of antennae, eyes prominent, numerous facets; antennae three 

 jointed, first joint shorter than third, wider and rounded at apex, second joint very- 

 small and round; apical, or third joint, longer than first, six or seven times longer 

 than second, and widening very much, claviform; thorax stout, nearly as wide as 

 long, and of an orange-yellow, excepting a crescent-shaped space (collare) next to the 

 head, which is bluish-black; abdomen longer than thorax, bluish-black, and decreas- 

 ing sharply to a point, ending in a rather long ovipositor; under surface uniform 

 bluish-black, with a few hairs on the different segments; wings hyaline, iridescent 

 and strongly ciliated, well rounded at apex, with short setae on the surface; legs pale 

 yellow, with five jointed tarsi, setaceous, femora somewhat swollen. Instead of a 

 tibial spur on hinder legs, there is a singular anomalous apical five-lobed appendage 

 (See Plate 2, fig. 15,) also two exterior spiny processes — coxae not quite touching each 

 other. Male not yet discovered. Inhabits Florida. Descril^ed from numerous speci- 

 mens, (pp. 29-31, pi. II, figs. 2-3, 6, 8, 12 and 15). 



From the unique type specimen in the United States National 

 Museum collection I make the following corrections and additions to 

 the specific description: 



General color not blue-black but bro\vn; a more or less obscure 

 spot on each side of the abdomen at distal two-thirds and the dorsal 

 thorax, lemon yellow, excepting the cephalic half or two-thirds of 

 the mesoscutum and all of the pronotum. Wings not hyaline but 

 distinctly embrowned out to a point slightly beyond (distad of) the 

 venation and including most of the base of the wing ; posterior wings 

 with proximal half slightly embrowned ; wings entirely without discal 

 ciliation but the fore wing bears an isolated bristle under the distal 

 three-fourths of the marginal vein, which is nearly as stout as some 

 of the bristles borne by the venation but smaller than most of them. 

 Distal half of the venation (marginal and stigmal veins) bearing 

 seven stout bristles, one of which is at the extreme end or apex of 

 the stigmal vein, the other six in pairs along the edges of the marginal 

 vein; the submarginal vein bears a single, smaller bristle before its 

 middle. Stigmal vein short, without a neck; marginal and submar- 

 ginal veins subequal in length, but the former much broader. Mar- 

 ginal cilia of the fore wing long and slender, slightly longer than the 

 greatest wing width, subequal to those of the posterior wdngs. Ovi- 

 positor slightly exserted. Middle tibial spur about subequal in 

 length to the proximal joint of the intermediate tarsi, not large, with 

 about six spines or lateral spurs. Cephalic tibial spur curved and 

 divided distad into about six unequal tines wliich lengthen distad. 

 Proximal tarsal joints of the intermediate legs not as long as the 

 combined lengths of the three distal joints but t\\ice the length of 

 the same joint of the tarsi of the other legs. Mandibles bidentate, 

 their tips nearly black. Antennal club slender, the antenna normal'
