free third and fourth antennal segments, and the character of the 

 ovipositor. 



The generic type is Scopodiplosis speciosa, new species. 



SCOPODIPLOSIS SPECIOSA, new species. 



This striking species was labeled S. Bernardino, Paraguay, K. 

 Fiebrig, collector. The abdomen was packed with eggs, the number 

 being estimated at 300. 



Female. — Length, 4 mm. Antennae as long as the body, thickly 

 haired, brownish yellow; 14 segments, the fifth with a stem one- 

 half the length of the cylindric basal 

 enlargement, which latter has a length 

 four times its diameter and a distinct 

 constriction near the basal fourth; low 

 circumfili occur at the basal and distal 

 portions of the indistinctly separated 

 apical part of the enlargement; terminal 

 segment with a tapering finger-like proc- 

 ess one-half the length of the subcylin- 

 dric basal enlargement, which latter 

 has a distinct subbasal constriction and 

 a length &ve times its diameter. Palpi ; 

 the first segment irregular subquadrate, 

 the second stout, with a length about 

 three times its diameter, swollen near 

 the basal third and truncate apically. 

 Eyes holoptic, dark brown. Mesono- 

 tum honey yellow, an irregular median 

 dark brown line with a marked expan- 

 sion anteriorly and two irregular dark 

 brown sublateral areas. Scutellum and 

 postscutellum yellowish white. Abdo- 

 men whitish yellow, sparsely clothed with white hairs. Wings yellow, 

 distinctly spotted, there being an irregular, broken, transverse, fuscous 

 band near the distal third and a somewhat linear fuscous area on the 

 branch of the fifth vein expanding and extending along the posterior 

 margin toward the anal angle. There is also an indistinct fuscous 

 area near teh base of the wing and occupying most of the anal angle; 

 costa mostly honey yellow, except the somewhat fuscous basal 

 fourth; subcosta uniting with the margin near the basal half, a 

 supernumerary vein extending from near the normal point of union 

 with the cross vein to the basal fourth of subcosta. This may be a 

 simple dilation and partial division of subcosta or a rudiment of the 

 cross vein; the third vein unites with the margin well behind the 

 apex, the fifth at the distal fourth, its branch near the basal half. 

 Coxae and femora basally yellowish, the distal portion of femora,
