BAGWORM MOTHS OP THE WESTERN HEMISPHERE 39 



Male. — (Fig. 2.) Vestui-e of wings and body dark fuscous. Anten- 

 nae (fig. 364) with 17-19 segments; sensory haii's approximately 2.5- 

 3x diameter of pectinations in length. First tarsal segment equal 

 length in all legs (fig. 171). Tibial spurs nearly as long as or equalling 

 length of first tarsal segment. Hindfemur slightly swollen, outer Ji 

 distinctly lighter color than rest of leg. Wings evenly, thinly, uni- 

 formly covered with very narrow hau'like scales (fig. 321). Wing 

 expanse 11.5-15 mm. 



Male genitalia.- — (Fig. 245.) Apex of tegumen rounded, with 

 prominent cleft. Aedeagus with base slightly expanded. Eighth 

 sternite (fig. 190) with anterior and posterior margins curved inward. 



Case. — (Fig. 66.) Length 13-15 mm.; diameter 3-4 mm. Roughly 

 cylindrical, approximately same diameter throughout; covered with 

 longitudinally arranged pieces of grass that usually extend entire 

 length of case. 



Types. — Lost {B. pulla Esper); in Deutsches Entomologisches 

 Institut {C.jiehrigi Koehler, lectotype). 



Type localities. — Europe {B. pulla); Paraguay {C.jiehrigi). 



Recorded hosts. — "Poaceae; grasses" (Strand in Seitz, 1913). 



Distribution. — In the Western Hemisphere this species is known 

 only from the Argentine Mesopotamia of Paraguay. In the Old 

 World E. pulla reportedly is found from Asia Minor west through 

 Romnania and Italy to Great Britain. (For a more thorough review 

 of the Old World distribution, see Tutt, 1900.) 



Discussion. — In 1939 Koehler described two male specimens of a 

 small moth collected in Paraguay by Karl Fiebrig. Koehler selected 

 these two specimens (one of which has been designated as a lectotype 

 by the present writer) as cotypes of a new species that he named in 

 honor of Dr. Fiebrig, who was at one tune the Du'ector of the Botanical 

 Gardens of Asunci6n, Paraguay. The statement of dedication by 

 Koehler suggests two possibilities: first, the two cotypes were collected 

 by Fiebrig in or near Asuncidn; second, they were probably collected 

 on or near the grounds of the Botanical Garden itself. If the latter 

 possibility is an actuality, the probability follows that CochUotheca 

 Jiehrigi represents an alien insect that had been introduced into the 

 locality on imported plant material. This appears to be a correct 

 conclusion since Koehler's species has been found to be identical with 

 the Old World species Epickno pterix puUa.
