Female. — Length, 7 mm. Clypeus deeply squarely emarginate, 

 the lobes subparallel sided, rounded apically; supraclypeal fove83 

 deep, incompletely confluent with the antenna! fovese; antennal 

 foveas poorly defined; antennal furrows broad shallow, nearly com- 

 plete; middle fovea deep, nearly circular in outline; ocellar basin 

 angulate above, below the anterior ocellus parallel-sided; postocellar 

 area well defined, divided by a longitudinal furrow in the middle; 

 postocellar furrow present, straight, well behind the ocelli, connected 

 "v\dth the angulate portion of the ocellar basin ; postocellar line some- 

 what longer than the ocellocular line; third and fourth antennal 

 joints subequal; mesonotum sparsely punctured, the anterior part' of 

 prescutum and posterior part of scutellum with the punctures 

 denser; scutellar lobe coarsely, closely punctured; second recurrent 

 interstitial with the second transverse cubitus ; sheath straight above, 

 strongly tapering below from the rounded apex. Black; clypeus, 

 labrum, mandibles (except piceous apices), four anterior legs, pos- 

 terior tibise except apices pallid; pronotum^ tegulse, propodeum, 

 three basal segments of the abdomen testaceous; margins of pre- 

 scutum and scutellar lobe rufo-testaceous. Wings hyaline, slightly 

 yellowish; venation pale brown, costa and stigma yellowish. 



Male. — Length 7 mm. Ocellar basin not as well defined as in 

 female; hypopygidium long, broadly rounded apically. Structural 

 characters those of female. Differs in color from the female in having 

 the following parts black: clypeus, labrum, mandibles, prescutum, 

 scutellar lobe, and propodeum. 



Biscayne Bay, Florida. A female and male. 



Type^— Cat. No. 14593, U.S.N.M. 



CAULOCAMPUS, new genus. 



Belongs to the Hemichorini and is related to Craterocercus Rohwer 

 from which it may be separated by the following characters: Tarsal 

 claws with an erect inner tooth near the middle; head and thorax 

 shining, not coarsely punctured; third antennal joint longer than the 

 fourth; eyes elongate oval; transverse radius wanting. 



Clypeus shallowly emarginate; malar space practically wanting; 

 eyes elongate oval; face very broad; pentagonal area obsolete; 

 lateral ocelli on the supraorbital line; antennae stout, pedicellum 

 longer than wide, third joint longer than the fourth; head and thorax 

 shining, not strongly punctured; hind basitarsis much shorter than the 

 following joints; tarsal claws with a small erect inner tooth; sheath 

 long, slender; venation similar to Eoplocampa Hartig, except the 

 transverse radius is wanting and the anal cell is more broadly con- 

 tracted. 



Superficially Caulocampus resembles Iloplocampa, not only in the 

 .a-dults but in the larvae (both larvae being internal feeders). The
