gin ; posterior angles with one long hair and posterior margin 

 with a row of about ten slender hairs ; the middle coxae show 

 through as curving brown bands in the region of the anterior 

 angles ; pale brown bands cut across the posterior angles from 

 the lateral margins and extend nearly across the first segment 

 of the abdomen. Legs long and stout, with swollen femora and 

 slender tibiae, and well-developed tarsi ; .pale throughout, with 

 a few short hairs. 



Abdomen clear with very pale smoky transverse bands (hardly 

 noticeable) and wide, perfectly clear sutures; lateral angles pro- 

 truding slightly, with one long and two shorter hairs ; posterior 

 margin of segments furnished with a row of fine hairs, while a 

 second row runs across the middle of each segment except the 

 first, eighth, and ninth; ninth segment with one long and two 

 shorter hairs on each side of the rounded posterior margin, and 

 some shorter ones between ; in the lateral portion of segments 

 one to eight are smoky brown spots with a darker rounded pro- 

 tuberance in the median portion ; genital hooks short, of me- 

 dium size, and typical of the genus. 



A single male collected on Ortalis cinerciccps, at Juan Vinas, 

 Costa Rica, March, 1902. This species resembles pallescens N. , 

 but is much paler, has very slender tarsi, while the markings of 

 the head and thorax differ considerably. 



Menopon fasciatum Rud., pi. VIII, fig. 4 



Rudow, Zcitsch. f. d. ges. Nat. XXIV, 403. 

 Giebel, Insccta Epizoa, p. 279. 

 Piaget, Les PcdicxiUnes, p. 418. 

 Female. — Body, length 2.08 mm., width .93 mm. ; head 

 length .38 mm., width .69 mm. 



Male. — Body, length 2.00 mm., width .84 mm. ; head, length 

 .35 mm., width .64 mm. 



Although the description is vague enough to fit any one of 

 several closely related species, from the fact that my specimens 

 were collected on the same host as Rudow's, and that what de- 

 scription he does give agrees very well with this specimen, there 

 seems to be no reason for creating another species.
