no. 3608 CADDIS FLIES, IV — FLINT 7 



Holotype, male: Mexico (San Luis Potosi), El Salto, about 25 miles 

 west of Antiguo Morelos, July 11-14, 1963, Duckworth and Davis. 

 Para type: Same data, 1 cf. 



Chimarra (Curgia) aureopunctata, new species 



Figures 19-21 



The species is related to C. barrettae (Banks) and C. banksi (Ulmer) 

 as is shown by the very similar shape of the ninth and tenth segments 

 and the claspers. From both it differs most noticeably in the shape 

 of the eighth tergum, which is divided deeply dorsomesally. 



Adult. Length of forewing 6-6.5 mm. Color brown, forewing 

 with many spots of golden hair intermingled with the brown. Male 

 genitalia: Eighth tergum produced ventrolaterally, deeply divided 

 mesally; ventrolaterally produced into a flattened lobe that overlies 

 a narrow, ventral setiferous process. Ninth segment with meso- 

 ventral lobe about as broad as long. Cercus about twice as long as 

 broad. Tenth tergum developed into a mesal hood bearing many 

 sensillae. Clasper developed into a dorsal point and a broader ventral 

 lobe. Aedeagus tubular, internally with four short black spines and 

 a pair of interlocking C-shaped sclerites. 



Holotype, male: Costa Rica, Turrialba, Feb. 22-28, 1965, 

 Duckworth. 



Paratype: Same data, 1 cf . 



Chimarra (Curgia) lobata, new species 



Figures 22-24 



This species also belongs to the C. barrettae group and seems closest 

 to C. persimilis Banks, from which it differs in the relatively unmod- 

 ified eighth tergum, lack of an elongated ventral lobe from the tenth 

 tergum, and the lack of a ventral lip on the aedeagus. 



Adult. Length of forewing 6.5 mm. Color in alcohol uniformly 

 pale brown. Male genitalia: Eighth tergum with posterior margin 

 rounded in lateral view, from dorsum with rounded submesal lobes. 

 Ventromesal process of ninth segment about as long as broad. Tenth 

 tergum developed into a narrow hood dorsally and a broader baso- 

 lateral lobe. Clasper elongate, tapering toward dorsoapical angle. 

 Aedeagus with two short black spines, a slender dark rod, and two 

 C-shaped sclerites. 



Holotype, male: Panama, Canal Zone, Rio Agua Salud, Mar. 30, 

 1965, Duckworth.
