78 PROCEEDIXGS OF IHE XATIOXAL MUSEUM vol.74 



Frons a little broader than long, all bristles well developed, the 

 ocellars slightly longer than anterior orbitals, postverticals well 

 below vertex; arista plumose; face slightly and evenly convex; hairs 

 on margin of chock short and regular. Thorax normal, intradorso- 

 central hairs in about 12 series; anterior sternopleural short. 

 Abdomen rather broad, tapered to apex, the apical tergal bristles 

 well developed; apical arm of eighth tergite black, broad, terminat- 

 ing in a short sharp tip which is curved forward, and with a similar 

 short thorn on its hind margin near base. Legs normal, fore femur 

 with an anteroventral comb; mid femur with a series of short hairs 

 on basal half of anteroventral surface. Inner cross vein a little 

 proximad of middle of discal cell; apical section of fourth vein very 

 slightly longer than subapical section. 



Length, 5 mm. 



Type.—C2it. No. 41138, U.S.X.M. Mount Maquiling, Luzon 

 (C. F. Baker). 



This species was received after the manuscript of the paper was 

 completed and circumstances prevent me from figuring the hypopy- 

 gium. 



HOMONEURA (HOMONEURA) BIOCULATA (de Meijere) 



Lauxania hiocultata de Meijeke, Tijdschr. v. Ent., vol. 57, p. 225, 1914. 



I have before me a Javanese specimen of this species sent to me by 

 Doctor de Meijere. The general color is paler than that of the next 

 species, there i,s but one pair of abdominal spots visible, the longest 

 hairs on arista are not longer than widtli of the third antemial seg- 

 ment, and the length of the insect is less than that of signata. 



It is very similar to kerteszi (de Meijere) { = orientalis Kertesz), 

 but I have onlj' a damaged specimen of the latter which lacks the 

 antennae so can not give a reliable diagnosis, and merely quote de 

 Meijere's differentiating cliaracter. 



I consider it highl}' probable that ocknpennis (Frey) is this 

 species. 



HOMONELRA (HOMONEURA) IMMACULIPENNIS, new species 



Male. — Entirely testaceous yellow, shining. Ocellar spot hardly 

 darkened. Abdomen with three black ^pots on fourth tergite, and 

 five on fifth. Wings yellowish hyaline. 



Frons a little wider at vertex than long at centre, narrower at 

 anterior margin, inner vertical bristles about twice as long as outer 

 pair, the latter as long as posterior pair, and a little closer together 

 than these; arista long plumose. Thorax with three pairs of long 

 po3tsutural dorsocentrals, the anterior pair close to suture, one pair 

 of prescutellar acrostichals, eight series of intradorsocentral hairs, 

 and the anterior sternopleural shorter than posterior one. Hypo- 

 pygium as Figure 81. Fore foiuur with anteroventral comb; all
