long, the hairs on arista are not much longer than its basal diameter, 

 the thorax has three pairs of postsutural dorsocentrals, and two dis- 

 tinct sternopleurals. The hypopygium is shown in Figure 50. 



Originally described from Sumatra. I have before me a male from 

 Kolambugan, Mindanao (C. F. Baker). 



HOMONEURA (MINETTIOIDES) CRASSIUSCULA (de Meijere) 

 Lauxanla crassiuscula de Meijere, Tijdschr. v. Ent., vol. 53, p. 128, 1910. 



This species is more robust than the preceding one and has the 

 frons fully twice as long as wide at anterior margin instead of about 

 1.5 as long as wide, and the sternopleura is largely fuscous instead of 

 entirely yellow. 



I have seen only a female of this species, from Sumatra. 



HOMONEURA (MINETTIOIDES) FUMIPENNIS (Malloch) 



This species was described in " Entomologische mitteilungen *' 

 (May, 1927, p. 169). It is readily distinguished as indicated in the 

 synopsis, and is known only from Formosa. 



I have seen two Samoan species referable here. 



Subgenus Homoneura Van Der Wulp 



There are several segregates which I still retain in Homoneura 

 that ought to be considered as entitled to subgeneric separation, but I 

 leave further subdivision to the future, believing that there must be 

 man}^ species yet unknow^n in this region, and possibly some of the 

 groups now appearing quite well distinguished may be connected 

 by means of yet unknown forms so closely that lines of demarcation 

 will disappear. 



Genotype. — Homoneura picea van dor AVulp. 



HOMONEURA (HOMONEURA) PILISETA, new name ( = PUBISETA de Meijere) 



Very similar structurally to muUseta (Kertosz), but, in addition 

 to the charaters mentioned in the key, the frontal orbits are densely 

 pale gray dusted and at the upper bristle not over half as wide as 

 interfrontalia at same point. Legs mostly black. 



Habiiat. — Sumatra. 



The specific name pubiseta was used by Kertesz for another 

 species in 1900. 



HOMONEURA (HOMONEURA) EXIGUA (de Meijere) 



Lauxania cxigua ue Meijere, Ti.jdsclir. v. Ent.. vol. .51. p. 141, 1908. 



This small species has the frontal orbits not over one-fourth of the 

 width of the interfrontalia, and the anterior pair of thoracic dorso- 

 centrals much more reduced in size than in the other three species of 

 this group. 



Habitat. — Java.
