and darker and have minor structural differences in head form, shape 

 of the submentum, etc., and Cuia two-branched. The writer has seen 

 specimens from Trinidad that indeed possess some or all of the char- 

 acters of the mainland series, but this is regarded as a normal phe- 

 nomenon associated with certain subspecies populations. It is likely 

 that large series from each area will exhibit a preponderance of one 

 or the other combination of characters with a certain percentage of 

 discrepant individuals, which can be assigned to their proper sub- 

 species only upon distributional data. 



CLOTHODA AEQUICERCATA (Enderlein) 



FiGrKES 10-13 



Antipaluria aequicercata Endeeleik, 1912, p. 63. — Navas, 1918, p. 107. 

 Clothoda aequicercata (Enderlein) Davis, 1939c, p. 379. 



This species, known heretofore by only the unique male holotype 

 from Colombia with damaged terminalia, is here redescribed from a 

 perfect male from the same country which fits Enderlein's original 

 description so well that it is believed to be conspecific with the holo- 

 type of aequicercata. 



Plesiotype male. — Color (on slide) uniform dark chocolate brown; 

 head, prothorax, and forelegs somewhat darker; five terminal an- 

 tenna! segments cream-colored. Length 16.5 mm.; forewing length 

 10 mm., breadth 2.5 mm. 



Head (fig. 11) large, quadrate, nearly as broad at caudal angles 

 as behind eyes ; sides scarcely convergent, very slightly arcuate ; caudal 

 margin truncate, deeply emarginated on each side at postoccipital 

 sutures, region between broadly arcuate. Antennae 23-segmented 

 (apparently complete). Mandibles stout, similar to those of inter- 

 media but strongly curved downward apically. Submentum (fig. 10) 

 much broader than long ; sides strongly convergent, somewhat arcuate. 

 Ventral bridge extensive, one-half longer than length of submentum. 

 Occipital foramen rounded apically; as broad as long. 



Wings relatively short and broad, venation and cross veins similar 

 to intermedia (pi. 18, A) ; Cu^a in both wings with but one branch. 



Terminalia (figs. 12, 13) relatively small. Ninth tergite (9) 

 elongate, only four times as broad as median length ; basal margin 

 biemarginate ; as elongate at median arcuation as at sides; apical 

 region extensively membranous medially. Tenth tergite broadly cleft, 

 but not entirely to base; left hemitergite (10 L) triangulate; process 

 (10 LP) distinct, inwardly directed caudiid at 45°, curving straight 

 back and outward at apex; right hemitergite (10 R) more trans- 

 verse than 10 L; process (10 RPi) indefinite, lobelike; inwardly 

 slanting, narrow, sclerotic process (10 RP2) (connected to 10 RP in 

 intermedia) isolated in membrane. Ninth sternite (H) broad basally,
