ing into membrane and reaching apical margin between R and M. 

 Wings more or less infuscate. 



Anal segment of male not very long, anal foramen situated at 

 middle, in profile anal segment weakly declivous distad, lower lateral 

 margin rectangulately produced ventrad at middle; in dorsal view 

 anal segment slightly tapering distad of anal foramen, apical margin 

 deeply convex. Pygofer with dorsolateral angles prominent, lateral 

 margins shallowly concave. Aedeagus curved upward distad, a 

 spinose process, in the form of an inverted Y, on each side near apex, 

 closely adpressed to aedeagus; a pair of long spinose processes arising 

 ventrally aad slightly subapically, directed cephalad below aedeagus, 

 sinuate in their basal half. Genital styles subovate, in side view 

 with ventral margin shallowly convex, dorsal margin straight, strongly 

 ascending to process, thence deeply concave to apical margin, which 

 is convex; dorsal process bent laterad at apex in a small horizontal 

 subtriangular plate. 



Anal segment of female very long and narrow, evenly decurved 

 throughout, anal foramen situated a little basad of middle. Ovipositor 

 with valvulae long, narrow, and decurved, tapering distally to acumi- 

 nate tip. 



Pregenital sternite markedly produced ventrocaudad, in antero- 

 ventral view deeply convex, not twice as broad across base as long 

 in middle line. 



Male, length 5.5 mm., tegmen, 5.0 mm. Female, length 4.0 mm., 

 tegmen 5.6 mm. 



Specimens examined: 13 males (one the holotype, USNM 62017), 

 3 females (one the allotype), and 1 nymph, 1,200 ft., Ridgefield, 

 Dominica, B. W. I., June 18, 1940, Fennah. This species would 

 appear to be nearest to Colpoptera fusca Caldwell in the shape of the 

 aedeagus, but the two are not closely similar even in this structure, 

 and they differ in the relative length of the ventral spines. More 

 obvious differences are to be found in the shape of the anal segment 

 of the male, of the pregenital sternite of the female, and in bodily 

 coloration. 



This species, which inhabits high montane forest, differs profoundly 

 from all species of Colpoptera so far described in the shape of the 

 female genitalia, which may be compared with those of Syrgis and 

 Tempsa from the Orient, or with those of species assigned to the sub- 

 genus Cheiloceps or Thionia (see p. 24).

Closely similar in size and form to C. meleagris, new species. 

 Light testaceous ; clypeus and a broad even band along middle of 

 frons slightly but distinctly darker, abdominal sclerites yellowish
