HOMONEURA (EUHOMONEURA) LUNATA (de Meijere) 



Lauxania lunata db MEijEaiE, Tijdschr. v. Ent., vol. 53, p. 135, 1910. 



I have figured the wing of a Javanese example of this species sent 

 to me by Doctor de Meijere (Fig. 47). I have before me a specimen 

 from Baguio, Benquet Province, which has the hmate spot in the anal 

 cell separated from the large basal dark area, and the latter is not 

 carried forward along the posterior margin of cubitus (fifth vein), 

 its outer margin running straight to the vein. I believe this speci- 

 men belongs here, but would like to see more material in order to 

 determine the degree of variation in the markings of the species. 



Another Philippine specimen from Billiran Island (C. F. Baker). 



I can detect no differences between this species and iirorata de 

 Meijere and consider the latter is a synonym of lunata. 



HOMONEURA (EUHOMONEURA) ORNATIPENNIS (de Meijere) 



Lauxania ornatipennis de Meijere, Tijdscbr. v. Ent., vol. 53, p. 141, 1910. 



This species differs from lunata in having the cloud on outer cross 

 vein extending broadly to margin of wing and to apex of fifth vein, 

 and no small dark dot between that cloud and the preapical fascia. 



One specimen, Mount Maquiling, Luzon (C. F. Baker). 



I have seen this species from Java and Australia [atrogrisea 

 Malloch). 



HOMONEURA (EUHOMONEURA) LUNIPENNIS (de Meijere) 

 "Lauxania limipennis de I\lEi.TBa?E, Tijdsclir. v. Ent., vol. 67, p. 50, 1924. 



This species has a dark vitta extending from anterior margin of 

 mesonotum just mesad of the humeral callus to beyond base of wing, 

 which is only present in part in ornatipennis. The wings in both 

 species are very similar, but in the type specimen of lunipennis the 

 anal field has the lunate spot much larger and connected on hind 

 margin with the basal cloud, so that there is a small hyaline inclosed 

 area in the center of the dark portion. 



Habitat. — Sumatra. 



MINETTIOIDES, new subgenus 



This subgenus is similar to Hotnoneura -vera., but differs in having 

 the thorax with a pair of short, but distinct, intra-alar bristles. 

 Subgenotype. — Lauxania parvinotata de Meijere. 



HOMONEURA (MINETTIOIDES) PARVINOTATA (de Meijere) 

 Lauxania parvinota de Meijere, Tijdschr. v. Ent., vol. 57, p. 231, 1914. 



A testaceous yellow species, with a pair of round black spots on 

 fifth tergite, and sometimes a much smaller pair on sixth. The 

 ocellar bristles are rather small and weak, both pairs of orbitals are 

 2609—29 5
