52 U.S. NATIONAL MUSEUM BULLETIN 244 



Female. — Unknown. 



Case. — (Fig. 70.) Length 24 mm.; diameter 7 mm. Irregularly 

 covered with tiny pieces of plant material as well as loosely attached, 

 larger fragments of herbaceous plant stems. 



Type. — Lost. 



Type locality. — Paramaribo, Dutch Guiana. 



Recorded hosts. — (?) "cordinia," from specimen label. 



Distribution. — (Map 9.) From the Canal Zone of the Panama- 

 nian Arc, south to the Guiana Highland of Venezuela, and along the 

 Guiana Coastal Plain to the Parana Plateau of southern Brazil. 



Discussion. — This species is related closely to C. watsoni and it 

 diverges slightly from the other species of Cryptothelea. The simi- 

 larity in structure of the male genitalia, legs, and general venation, 

 however, clearly associates this species with the other members of 

 the genus.
