Colpoptera ntemnonia, new species 



Figure 2, a-i 



Testaceous-fuscous; frons laterally, genae anteriorly, and sides of 

 clypeus pallid stramineous, sides of vertex, anterior and posterior mar- 

 gin of pronotum, disc of mesonotum, a sinuate suffusion between disc 

 and tegulae, and metathoracic pleurites fuscous-piceous. Tegmina 

 hyaline at base and between R and costal margin, remainder of corium 

 and clavus fuscous-piceous as far as nodal line, membrane, except 

 anterior to R, brown. Wings hyaline, suffused with brown in distal 

 half. 



Anal segment of male with anal foramen situated about one-third 

 from base, in lateral view strongly deflexed distad of anal foramen, with 

 upper margin concave and lower sinuate, lateroapical angles broadly 

 triangularly produced ventrad, apical margin convex. Aedeagus 

 broadly tubular, shallowly curved upward distaJly, armed ventro- 

 laterally on left about one-fifth from apex with a moderately short 

 stout spine directed cephalad and slightly curved dorsad at apex; a 

 corresponding spine on right side of same shape but distinctly longer; 

 a pair of broadly Y-shaped processes arising near the base of these 

 spines, directed dorsad and closely investing aedeagus. Genital styles 

 subovate, dorsal margin in its basal half strongly bent laterad, dorsal 

 process in anterior view with a stout decurved spine on outer side 

 near base, thence shallowly tapering distad to rounded apex, in lateral 

 view bent cephalad in apical third. 



Anal segment of female in profile very narrow and almost straight 

 distad of anal foramen, Pregenital sternite only moderately produced 

 ventrocaudad distally, its hind margin in anteroventral view broadly 

 truncate-convex, very much thickened, and devoid of any eminence 

 on dorsal surface. 



Male, length 6.0 mm., tegmen 6.9 mm. Female, length 7.0 mm., 

 tegmen 6.9 mm. 



Specimens examined: 1 male (holotype, USNM 62014) and 1 

 female (allotype), 1,000 ft. in mountain forest, Dominica, B. W. I., 

 July 6, 1939, Fennah. This species is near to Colpoptera monticolens 

 Dozier, new combination, and Colpoptera nemonticolens Caldwell, new 

 combination. It differs from them in the shape of the male anal 

 segment, in the shape and length of the aedeagal processes, in the 

 shape of the dorsal margin of the genital styles, and in the coloration 

 of the frons. 



Colpoptera cyatheae, new species 



Figure 3,n-r 



Vertex broader across apex than long in middle line (2.7:1), frons 

 in middle line as long as broad.
