from Puh'inaria on citrus collected in Manila, P. I. The species is 

 tentatively referred to the above named genus, particularly as its 

 habits differ from the normal Rhahdophaga to which it is closely 

 related. 



Male. — Length 1.2 mm. Antenns probably nearly as long as the body, 

 rather thickly haired, dark brown, yellowish basally ; at least twelve and prob- 

 ably fourteen segments, the fifth with the stem one-half the length of the 

 cylindric basal enlargement, which latter has a length about twice its diameter 

 and a thick subapical whorl of long, stout setae. Palpi : first segment irregu- 

 lar, the second with a length nearly three times its diameter, the third a little 

 shorter, more slender, the fourth over one-half longer than the third and 

 somewhat dilated. Mesonotum dark brown, the submedian lines, scutellum 

 and postscutellum yellowish. Abdomen pale yellowish. Wings hyaline, the 

 third vein uniting with the margin at the apex of the wing. Halteres and 

 legs a nearly uniform yellowish straw. Claws long, strongly curv^ed, uni- 

 dentate, the pulvilli rudimentary. Genitalia ; basal clasp segment short, 

 stout; terminal clasp segment somewhat reduced, swollen basally and tapering 

 to a heavily spurred apex ; dorsal plate deeply and triangularly incised, the 

 lobes tapering and irregularly rounded apically ; ventral plate long, broad, 

 broadly rounded distally. 



Female. — Length 1.2 mm. Antennae nearly as long as the body, sparsely 

 haired, probably fourteen segments, the fifth with a stem one-fifth the length 

 of the cylindric basal enlargement, which latter has a length a little over 

 twice its diameter and a moderately thick subapical whorl of long, curved 

 setje. Ovipositor with a length about one-fourth that of the abdomen, the 

 terminal lobes narrowly oval, tapering distally and sparsely setose, otherwise 

 nearly as in the male. 



Type Cecid, a2494. 



Dentifibula ceylanica new species. 



The one insect described below was reared by Prof. A. Ruther- 

 ford, Royal Botanic Gardens, Peradeniya, Ceylon, June 8, 1914, from 

 twigs of Cassia alata infested with a species of Hemichionaspis. 

 This species is distinguished from D. obtiisilobcc by the relatively 

 shorter basal portion of the stem of the fifth antennal segment and 

 the nearly straight inner margin of the apical lobe of the basal clasp 

 segment. The two Indian species of Dentifibula are readily sep- 

 arated from American forms by the shorter and relatively broader 

 apical lobe of the basal clasp segment. 



Male. — Length i mm. Antennas as long as the body, sparsely haired, 

 pale yellowish ; fourteen segments, the fifth having the stems with a length
