acrostichals, and two sternop>leurals. Fore femur with an antero- 

 ventral comb; fore tibia quite sharp on dorsal surface. Last three 

 sections of fourth vein subequal in length. 



Length, 3.5 mm. 



Localif I/. —Cuevnos Mountains, Negros (C. F. Baker). Originally 

 described from Mindanao and Masbata by Frey, who placed it in the

HOMONEURA (NEOHOMONEURA) ABERRANS (de Meijere) 



Lauxaiiia aderrans de Meijebe, Tijdschr. v. Ent., vol. 58, p. 90, 1915. 



This is a strikingly colored species, being testaceous yellow, with a 

 black central streak on occiput, a broad black dorsal vitta on thorax 

 which extends almost to tip of scutellum, and a similar black dorsal 

 vitta on abdomen. The wings are hyaline, antennae, palpi, and legs 

 yellow. 



The species differs from most of its allies in having the frons 

 longer tlian wide and distinctly widened from vertex to anterior 

 margin, and the ocellar bristles fine and minute. The arista is long 

 plumose, the eyes are narrowed below and slightly emarginate on 

 lower half behind; dorsocentrals three pairs, acrostichals one pair. 

 Hypopygium very large, the superior forceps strong, tapered, extend- 

 ing forward to beyond middle of abdomen. Fore femur with an 

 anteroventral comb ; mid tibia with a series of short posterior setulae 

 and one long and two shorter apical ventral bristles; hind femur 

 with two or three preapical anteroventral bristles. 



Length, 5 to 6 mm. 



Locality. — Singapore (C. F, Baker). I have not seen it from the 

 Philippines.
