FREYSUILA DUGESII Aleman. 



Figs. 122, 124, 408. 



Freysuila dugesii Aleman '87:21. 



Freysuila dugesii ScawAnz '97:197. — Crawford 'lib: 491. 



Length of body 3 mm.; length of forewing 4.8; width of head 0.95; 

 length of antennae 4. General color flavous; antennae black on seg- 

 ments V-X, basal joints flavous. 



Head broad, surface smooth or very finely punctate. Anterior 

 ocellus in front at base of cleft; gense produced beneath into a pair 

 of small conical processes directed downward. Antennae longer 

 than body; I and II very large; III not quite twice as long as IV, 

 fusiform, and very thick in the middle; IV to X more slender. Legs 

 long, rather thick. Wings large, broadly rounded at apex; veins 

 flavous; first marginal cell much larger than second. M-l-Cu shorter 

 than R. 



Genitalia. — Female. — Genital segment as long as rest of abdomen, 

 about 1 mm. long; dorsal valve longer than ventral, acutely pointed; 

 both valves with a tuft of long hairs near apex. 



Described from two females from Guanajuato, Mexico (Duges), on 

 Cedrela sp. These are two of the specimens sent by Mr. Duges to 

 the United States National Museum some years ago, on which Schwarz 

 based his description. 



FREYSUILA ERNSTII Schwarz. 

 Freysuila dugesii ernstii Schwarz '97:197. 



Very close to dugesii, differing in only a few respects ; third anten- 

 nal segment only a little longer than fourth ; genae swollen much less, 

 processes not conical. Wings broader; M-|-Cu equal in length to R; 

 pterostigma a little longer; vems black. 



Genitalia. — Male. — Anal valve small, not longer than forceps, sim- 

 ple; forceps thick, cultrate, acute at apex, inner edge rather sharp. 



Described from one male (para type), from Caracas, Venezuela 

 (A. Ernst), on Cedrela, April 20, 1894. 



FREYSUILA CEDREL.^: Schwarz. 

 Fig. 417. 

 Freysuila dugesii cedrelse Schwarz '97: 197. 



Close to dugesii, differing as follows: Color flavous, with a brown 

 streak on each side of vertex, another behind each eye, extending 

 to wing base; a bro-v\Ti spot on front of praescutum and a browii 

 stripe on each side of scutum just above the wmgs; venter yellow; 

 antenna entirely black. Third antennal segment nearly four times 

 as long as fourth; genal epiphyses acutely pointed. Wings large, as
