the ocellar tubercle. No buccal cavity, the vestiges of proboscis 

 and palpi appearing as three subequal short stumps projecting 

 from periphery of head in the oral region. Facets of upper- 

 anterior area of eye enlarged in male. Prosternal membrane 

 inflated bladderlike, more in female than in male, forming a 

 bipartite bufifer on which rests the lower occiput. 



Therobiopsis, new genus. 



Genotype, Aulacephala braueri Kertesz, 1899, Termes. 

 Fuezetek, xxii, 481-483. 



Differs from Aulacephala mainly in the apical cell being 

 closed in margin a little before wing-tip. The third antennal 

 joint is distinctly shorter than second. The female has two 

 strong verticals on each side, two proclinate and one reclinate 

 orbitals. Two sternopleurals, two postintraalars, three post- 

 suturals, one preacrostichal, and one postacrostichal. The 

 wings are without spots. 



Eutrixopsis, new genus. 



Genotype, Eutrixopsis jovana, new species. 



Facial carina low, flat, separating the antennae. Epistoma 

 narrow, wider than length of second antennal joint, receding 

 and widening below to oral margin. Facialia wide and bare 

 above, with closely set weak bristles below vibrissal angles. 

 Proboscis short. Male eyes contiguous, facets of lower fourth 

 distinctly smaller. Male lacking both verticals and orbitals ; 

 frontalia obscured by the parafrontalia meeting over them, 

 showing only slightly next lunula and ocellar triangle. Two 

 sternopleurals, one postintraalar, three postsuturals, no pre- 

 acrostichals, one postacrostichal. Apical cell open in tip. No 

 costal spine. Only weak marginal bristles on abdomen. 



Eutrixopsis javana, new species. 



Length, .">.,■) mm. One male, Pelaboean, Ratoe, Java (Bryant 

 & Palmer).
