Family LARVAEVORIDAE. 



DEJEANIOPALPUS, new genus. 



Genotype. — Dejeaniopalpus texensis, new species. 



Differs from Leskiopalpus as follows: Female. Palpi elongate, 

 subcylindrical, evenly narrowed on apical three-fifths, fuUy as long 

 as facial plate; when retracted extending almost the length of third 

 antennal joint beyond epistoma. Proboscis slender, the part below 

 geniculation rather longer than head height. Vertex nearly one- 

 third head width. Frontaha wider than posterior part of one para- 

 frontal, about as wide as anterior part. OceUars quite strong. First 

 vein bristled completely, third bristled to or beyond small cross vein. 

 Differs from Leskiomima principally in the long palpi; from SpatM- 

 palpus by arista short-plumose and only shghtly thickened on basal 

 third, the antennae inserted about on eye-middle; from Genea by 

 cylindrical palpi, antennae inserted on eye-middle and arista plumose. 



DEJEANIOPALPUS TEXENSIS, new species. 



Length of body, 6.5 mm. ; of wing, 5.25 mm. One female, Texas. 



Light fulvous to pale yellowish, including frontalia, antennae, palpi, 

 proboscis and legs, the tarsi brown to blackish, the middle and front 

 metatarsi yellowish. Parafrontals, face, cheeks and occiput thinly 

 silvery. Third antennal joint faintly infuscate on edge. Pleurae 

 silvery. Mesoscutum blackish in gromid color, brassy pollinose, 

 apparently with usual blackish vittae. ScuteUum brassy pollinose. 

 Abdomen without poUen, except very faint indications at the incis- 

 ures. Wings grayish, with only the faintest infuscation; veins yel- 

 lowish. Tegulae pale yellowish. 



Holotijpe.—^o. 20039, U.S.N.M. 



GYMNOERYCIA, new genus. 



Genotype. — Gymnoerycia rubra, new species. 



Differs from Erycia as follows: Female. Vertex less than one- 

 fourth head width, the front and face widening quite evenly from 

 same; the face inferiorly rather more than twice as wide as vertex. 

 Facial depression not so broad, the faciaha not so flattened. Only 

 one recUnate orbital; outer vertical but little longer than orbital 

 fringe. Frontaha a Httle narrower than one parafrontal. Faciaha 

 cihate halfway up or more. Parafacials narrow, the head shorter. 

 Third antennal joint fuUy three times second. Apical decussate 

 pair of scuteUar bristles fine, erect. Median marginal pair of first 

 abdominal segment vestigial, that of second rather weak. Larvi- 

 positor in the form of a short spoonlike lobe, chitinous, broad at base 

 and narrowing apicaUy. Hind tibiae rather closely pectinate, with 

 one longer bristle. Apical cell ending a httle nearer to wing tip, 

 cubitus nearer to hind margin, apical cross vein bowed in.
