d 1 . Circumfili of male coarse, very irregular, 4 or 5 transverse fill to a segment, 



the plates of the ovipositor triangular Feltomyia Kieffer. 1 



d 2 . Circumfili of male fine, about 18 transverse fili to a segment, the terminal 



lobes of the ovipositor roundly quadrate Eocincticornia, new genus. 



c 2 . Terminal clasp segment of the male bidentate, subapical, the ovipositor 



conical Daphnephila Kieffer. 



6 3 . Palpi uniarticulate, the flagellate antennal segments subsessile, the abdomen 

 with caducous scales, the short ovipositor biarticulate Ozobia Tavares. 



The drawings were all made with the aid of the camera lucida and 

 are more or less diagrammatic. The types or cotypes of the new 

 genera and species here described are in the United States National 

 Museum. 



MICROCERATA BUSCKI, new species. 



This small midge was collected in September, 1901, by Mr. August 

 Busck at Baracoa, Cuba. It is of interest largely because it shows 

 the subtropical distribution of the genus. 



Male. — Length, 1.2 mm. Antennae, as long as the head; 8 and 

 possibly 9 segments, the second enlarged, globose, the fifth broadly 

 pyriform, with a length one-fourth greater than its diameter, with a 

 sparse subbasal whorl of long, stout setae and a scattering subapical 

 whorl of short, stout spines. The eighth segment is slightly produced 

 and more or less fused with the narrowly fusiform ninth. Palpi one- 

 half longer than the antennae, the first and second segments subequal, 

 each with a length over twice the diameter, the third one-half longer 

 than the second, more slender, and the fourth about twice as long as 

 the second, more slender. Mesonotum dark brown, the submedian 

 lines sparsely haired. Scutellum reddish brown, postscutellum and 

 abdomen dark brown, almost black. Genitalia fuscous. Wings 

 hyaline, subcosta uniting with the margin near the basal half, the 

 third vein at the distal fourth, the fourth vein forking just beyond 

 the middle of the wing; the fifth joining the posterior margin at the 

 distal fourth, the sixth at the basal half. Hal teres and legs fuscous 

 yellowish red, the pulvilli as long as the simple curved claws. Geni- 

 talia; basal clasp segment long, tapering; terminal clasp segment 

 swollen basally, stout and about three-fourths the length of the basal 

 clasp segment; dorsal plate moderately long, tapering to an obliquely 

 rounded, thickly setose apex. Type Cecid. 1532. 



Type.— Cat. No. 18485, U.S.N.M. 



RUBSAAMENIA MULTINODA, new species. 



The species described below was labeled Fort Pikit, Mindanao, May 

 31, 1907, C. H. Halliday, collector. It can be easily distinguished 

 by the characters given below . 



i Judging from larval characters, this genus is closely related to and may possibly be a synonym of 

 Uleella Riibsaamen, a genus founded upon a larva.
