subquadrate* ill "outline, deep, walls nearly straight; antennal fur- 

 rows wanting; frontal foveas elongate, punctiform; ocellar basin 

 U-sbaped, sligbtly broader just below anterior ocellus; postocellar 

 furrow not complete; postocellar area defined laterally b}" furrows, 

 fully twice as wide as the cephal-caudad length; postocellar line 

 perhaps a little shorter than the ocellocular; pedicellum subequal 

 in length with the scape; fourth antennal joint slightly longer than 

 the third, antennsB slender; stigma long, tapering from near the 

 base to apex which is narrowly tnincate; transverse radius slightly 

 basad of the middle of the cell; third cubital cell shorter than the 

 second; first transverse cubitus incomplete; transverse median a 

 little more than its length from the apex of the cell; sheath very 

 broad, straight above, tapering to tnmcate apex-beneath. Black; 

 clypeus, labrum, four apical and two basal joints of the antennae, 

 pronotum, tegulse, first perapteron, large spot on dorsal margin of 

 metepisternum, margin of the prescutum, scutellum, scutellar lobe, 

 four anterior legs except bases of coxae, and tarsi, posterior coxae 

 and trochanters, base of posterior tibiae, abdomen except apical 

 segments and sides of some ventral segments, whitish. Wings

Tjibodas, Mount Gede, Java. One female collected September 

 10, 1909, by Bryant and Palmer at an altitude of 4,500 feet. 



Type.— Csit. No. 14506, U.S.N.M. 



NEOSTROMBOCEEOS, new subgenus. 



Clypeus distinctly arcuately emarginate; eyes gently converging 

 to the clypeus; malar space wanting; front without an ocellar 

 basm; lateral ocelli well below the supraorbital line; posterior 

 orbits rather narrow ; pedicellum wider than long ; the third antennal 

 joint longer than the fourth; third pleural suture angulate ventrally 

 extending from coxal process in a cephal-caudad direction then 

 curving to the wing process; metepisternum with a long dorsal arm; 

 metepimeron large; basitarsis III somewhat shorter than the fol- 

 lowing joints; claws cleft, with imier tooth of the cleft larger than 

 the outer; first transverse cubitus wanting; transverse median 

 slightly beyond the middle of the cell; hind wing ^^^th two discal 

 cells, lanceolate cell sessile. 



Neostroinhoceros may easily be separated from the other subgenera 

 of Stromhoceros by the cleft tarsal claws.
