like those of the preceding one, but they are at once distinguished 

 by the larger size, the black patches of the back of mesonotum, 

 the four scutellar bristles, and the hind cross vein of the wings 

 being not bordered with fuscous. In the last character they 

 agree with the variety C. c. nubilus Hendel, from Formosa; but 

 as I have said in another place, 13 I have never seen specimens 

 with broadly infuscated hind cross vein, in opposition to what 

 is stated by de Meijere.' 4 The Philippine specimens with in- 

 fuscated cross vein belong to the next, very distinct species, 

 C. mundus.

15. Chaetodacus mundus sp. nov. Plate I, fig. 9. 



Near the preceding species and closely allied to the Formosan 

 C. synnephes Hendel, but distinguished by the unspotted face 

 and the longer ovipositor of the female. 



Luzon, Laguna Province, Los Bafios (Baker), Paete (Mc- 

 Gregor). Panay, Antique Province, Batbatan Island (Mc- 

 Gregor). Mindanao, Davao (Baker). Type in Professor 

 Baker's collection. 



Male and female. — Length of body, 6 to 6.5 millimeters; of 

 ovipositor, 1.8 to 2; of wing, 6 to 6.5. Occiput rather convex 

 and shining, yellowish, with a broad reddish brown or blackish

 broad yellow border. Frons of usual shape, less than twice as 

 long as broad; dull yellowish, shining on sides and at vertex; 

 ocellar dot black, lateral and central darkish spots less developed 

 or even wanting. Lunula reddish brown. Antennas as long as

 linear; jowls as broad as third antennal joint; subocular spot 

 small, brown. Palpi broad, yellowish; proboscis dirty brown. 

 All the bristles black; usually two terminal pairs of lower orbital
