EMIBTOPTERA OF THE NEW WORLD — ROSS 411 



gradually convergent from sides at basal half; process (HP) not de- 

 veloped. Right paraproct obsolete. Left paraproct (LPPT) nar- 

 rowly fused to H basally, broadened and spatuliform apically. Left 

 and right cercus-basipodites (LCB, ECB) represented by small, nar- 

 row, ventral, setose, sclerotic areas. Left and right cerci subequal. 



Female. — No specimens definitely associated with male. 



Holotype. — Male (terminalia damaged), in Berliner Zoologischen 

 Museum (No. 2734). 



Type data. — Colombia (Moritz collection). 



Plesiotype (described above). — Male, on slide, in United States 

 National Museum, collected May 3, 1939, in plant quarantine at 

 Washington, D. C., in wild orchids shipped from Medellin, Colombia. 



Remarks. — It is difficult to understand why Enderlein placed this 

 species, as well as urichi, apart from Clothoda into his genus Anti- 

 paluria; aequicercata is closely related to urichi and intermedia but 

 may be separated from both by its much darker color, the broad, 

 parallel-sided head, the transverse submentum, the forked Cu^a vein 

 (usually simple in urichi^ usually 2-forked in intermedia and nohilis), 

 and the fact that the cleft of the tenth tergite does not attain the 

 base. 



A curious venational aberration is present on the left hindwing of 

 the plesiotype. The media unites with the anterior branch of Cuia, 

 and both veins continue to tl\e terminus as a single vein. The hyaline 

 stripe between the veins is abruptly terminated at the point of union 

 of the two. 



A female Clothoda at hand from Colombia, which appears to be 

 aequicercata, is easily distinguishable from those of urichi and inter- 

 media by its very dark color. The head, prothorax, and forelegs 

 (including tarsi) are blackish brown.

Old and New World Embioptera : Males with dentate mandibles — 

 three apical dentations on the right, two on the left. When winged, 

 E4+5 forked in both wings (except fore wing of Calamoclostes albistrio- 

 latus). Tenth abdominal tergite medially cleft to basal margin, each 

 hemitergite bearing caudal processes ; the left process usually narrow, 

 sclerotic, and more definite than the right process, which is generally 

 broad and not sharply defined. Composite left paraproct and left cer- 

 cus-basipodite well represented. Left cercus with basal segment al- 

 ways echinulate on inner side and sometimes strongly lobed. Hind 

 basitarsus with either one or two sole-bladders.
