Genus Ludlowia. 195 



light apical bands. There are also narrow apical bands on the first, 

 second and third tarsal segments, the remainder of the hind legs is missing. 

 In some cases the bands seem slightly to involve both segments, but in> 

 any case they are minute. 



Wing light and apparently partly denuded, but there are rather 

 broadly truncated, sometimes asymmetrical dark scales, with dark blue 

 green iridescence on costa, sub-costa, and first long vein, and a few of 

 the same 'broad-ended' scales on the other veins; first sub-marginal 

 cell about one-third longer and a third narrower than the second posterior,, 

 the base of the latter, however, being well interior to that of the first sub- 

 marginal. Stem of the first sub-marginal about one-third longer than 

 the cell and somewhat longer than the second posterior. Mid cross-vein 

 is about the same length as supernumerary, which it meets, and posterior 

 cross- vein is about one-fourth longer, and is distant from the mid about 

 three-fourths of its own length. 



Halteres light, knob brown scaled. 



Length. — 4 ' 5 mm. 



Habitat. — Bayamban, Pangasinan, Luzon, Philippine Islands. 



Time of capture. — May (15th). 



Described from one specimen taken by Capt. W. P. Chamberlain, after 

 whom it is named." 



This insect was placed provisionally under Mimomyia by Miss 

 Ludlow. It does not, however, come in that genus, because the 

 $ palpi in Mimomyia, although long, are not nearly so long as 

 the proboscis and end acutely and not clavate as in Ludlowia y 

 nor is the proboscis swollen as it is in Mimomyia. 



It comes in a new genus with the male I referred to in the 

 First Gordon College Report, p. 83 (1905). 



This genus is described here under the name Ludlowia from 

 Miss Ludlow's type which she kindly sent me.

$ . Proboscis black ; labellae paler \ palpi brown, a pale band 

 on the lower side of centre ; the apical segment, rather swollen 

 and bent, covered with scales and a few bristles. Antennae 

 plumose with a long terminal pilose segment. Head dark and 

 small, eyes deep purplish-black ; pale upright scales, not forked 

 over the vertex and occiput ; white flat scales on either side of 

 a dark median line of scales, a few black scales on the nape.
