one and one-half and three and one-half times their diameters, respectively, 

 the enlargements subglobose. Palpi : first segment subquadrate, the second a 

 little longer, more slender, the third a little longer and more slender than the 

 second. Mesonotum reddish yellow. Scutellum, postscutellum and abdomen 

 mostly yellowish. Wings faintly spotted at the fork of the fifth vein. 

 Halteres and legs pale straw. Claws moderately stout, strongly curved, the 

 pulvilli as long as the claws. Genitalia : basal clasp segment rather broad 

 and with a broadly triangular apical process, the length of the latter about 

 equal to its basal width ; the inner margin being nearly straight ; terminal 

 clasp segment swollen basally, enlarged apically and somewhat curved. Other 

 structures indistinct in the preparation. 



Type Cecid. 32580. 

 Dentifibula obtusilobae new species. 



The male characterized below was reared by Prof. A. Rutherford 

 of the Royal Botanic Gardens, Peradeniya, Ceylon, September 21, 

 1914, from Piper nigrum infested with Hemichionaspis aspidistra: 

 and a few specimens of Aspidiotus latanice. The midge is probably 

 an enemy of the first named scale insect. It may be most easily sep- 

 arated from the known American species by the relatively shorter 

 and much stouter apical process of the basal clasp segment. 



Male. — Length .75 mm. Antennas probably one-half longer than the 

 body, sparsely haired, dark brown, the stems whitish transparent, presumably 

 fourteen segments, the fifth having the stems with a length two and one-half 

 and four times their diameters, respectively ; circumfili well developed and 

 extending nearly to the base of the next enlargement ; terminal segments 

 missing. Palpi : first segment narrowly oval, the second a little longer, 

 rectangular, the third somewhat reduced, fusiform. Face and thorax yellow- 

 ish, the abdomen yellowish fuscous. Halteres whitish transparent, the legs 

 mostly pale straw, the tarsi mostly dark brown ; claws simple, evenly curved, 

 the pulvilli as long as the claws. Genitalia : basal clasp segment moderately 

 long, stout, and with a stout, triangular curved apical process, the latter with 

 a length about equal to its basal width and minutely dentate apically ; terminal 

 clasp segment short, stout, strongly curved, capitate. Other structures in- 

 distinct in the preparation. 



Female. — Length .75 mm. Antennae about as long as the body, sparsely 

 haired, dark brown, the stems whitish transparent ; fourteen segments, the 

 fifth with a stem one-fourth longer than the cylindric basal enlargement, 

 which latter has a length about twice its diameter ; terminal segment reduced, 

 with a length about three times its diameter and broadly rounded apically. 

 Abdomen fuscous yellowish, fuscous basally, the ovipositor short, the lobes 

 narrowly oval and thickly setose.
