 lowish. Wings hyaline, costa pale straw, subcosta uniting therewith 

 before the basal half, the third vein at the apex, the fifth near the

Type Cecid. a 1957 N. Y. State Museum. 



Lobodiplosis spinosa n. sp. 



This remarkable fly was taken at light, St. Johns, Antigua, 

 in January, 1909. The male is easily recognized by the greatly 

 produced genitalia, the peculiar spinose setae of the basal 

 clasp segment and the heavy, chitinous spines of the harpes. 

 The female, apparently taken in some numbers, is provision- 

 ally associated with the male on account of the two being cap- 

 tured together. 



Male. Length 1.5 mm. Antennae probably one-half longer than the 

 body, thickly haired, fuscous yellowish ; 14 segments, the fifth having 

 the basal stem with a length two and a half times its diameter, the 

 distal stem with a length three times its diameter, the basal enlarge- 

 ment subglobose, subbasal whorl thick, the circumfili short, extending 

 to the middle of the stem, the distal enlargement produced, with a 

 length two and a half times its greatest diameter, constricted near the 

 basal third, the basal circumfilum short, the loops extending to the 

 middle of the enlargement, the distal circumfilum rather short, the 

 loops extending to the apex of the enlargement; subapical whorl 

 rather thick, long. Palpi ; the first segment presumably short, stout, the 

 second with a length four times its diameter, the third as long as the 

 second, the fourth one-quarter longer and more slender. Mesonotum 

 apparently fuscous yellowish. Scutellum, postscutellum and abdomen 

 probably yellowish. Wings hyaline, subcosta uniting with costa at the 

 basal third, the third vein at the apex, the fifth at the distal fourth, its 

 branch near the basal half. Halteres pale yellowish. Legs yellowish 

 straw ; claws rather stout, strongly curved, the anterior unidentate. 

 Genitalia ; basal clasp segment long, very slender, slightly expanded 

 apically and with a distinct rounded lobe, the tip of the segment and 

 the lobe thickly clothed with long, stout, spine-like setae; terminal 

 clasp segment subapical, long, slender, slightly curved: dorsal and 

 ventral plates indistinct. Harpes long, chitinized, with a pair of
