Type. — Cat. No. 41139, U.S.N.M. Type and six paratyjjes, Mount 

 Maquiling, Luzon; one paratype, Los Banos (C. F. Baker). 



There are some females in my possession which I have placed with 

 the last two species, but whether correctly or not I have no means of 

 determinin*;. If the type of picea is a female it may not be possible 

 to identify it specifically. The females are distinguished by the struc- 

 ture of the apical abdominal sternites. (Figs. 97 and 98.) 



HOMONEURA (HOMONEURA) FOLIFERA Malloch 



Homoncura {Ilomoneura) folifcra Malloch, Suppl. Ent., vol. 15, p. 110, 1927. 

 HOMONEURA (HOMONEURA) OPPOSITA Malloch 



Eomoneiira {Homoneura) opposita Malloch, Suppl. Ent., vol. 15, p. 110, 1927. 



The above two recently described species are referable to the same 

 group and the hypopj'^gia are figured herein. (Figs. 66 and 63.) 

 They are from Sumatra, and may yet be found in the Philippines. 



HOMONEURA (HOMONEURA) OPACITHORAX. new species 



FeviaJe. — Head entirely black, whitish dusted, most noticeably so 

 on frontal orbits, face, cheeks, and postocular orbits; antennae, palpi, 

 and aristae, black. Thorax dull black, the dorsum evenly brownish 

 dusted. Abdomen shining black, but slightly dusted. Legs fuscous, 

 tibiae dusky testaceous, tarsi paler testaceous. Wings grayish hyaline, 

 not darkened at bases. Halteres yellow, knobs dark. 



Frons a little longer than wide, the bristles long and strong, 

 anterior orbitals over half as long as posterior pair, ocellars parallel, 

 a^ long as postverticals ; arista with very long hairs above, much 

 shorter haired below; third antennal segment quite large, about 

 twice as long as broad; face evenly and slightly convex. Thorax 

 with three pairs of long postsutural dorsocentrals, the prescutellar 

 acrostichals distinct, and six series of intradorsocentrals; anterior 

 sternopleural short. Abdomen rather sparsely haired. Fore fenuir 

 with antero ventral comb ; mid tibia without median posterior bristles ; 

 hind femur without ventral bristles. Inner cross vein at middle 

 of di^cal cell and a little beyond apex of first vein; penultimate 

 section of fourth vein less than half as long as ultimate section; 

 wing narrower than usual.

Type.—C2ii. No. 41158, U.S.N.M. Mount Maquiling. Luzon (C. 

 F. Baker.) 



HOMONEURA (HOMONEURA) PICEOroES, new species 



Male. — Very similar to the species of the dentifera group in habitus 

 and coloration. There is no discernible white dusting round the 

 propleural spiracle nor on anterior part of thoracic dorsum, and 

 the ba^e of the wing and apex of auxiliary vein are not infuscated.
