BAGWORM MOTHS OF THE WESTERN HEMISPHERE 85 



DiscussiON.^ — ^The type specimen along with two slide preparations 

 of Hyaloscotes inthojioera have been re-examined closely with the 

 resulting discovery that certain minor morphological features, although 

 taxonomically important, were given incorrectly in Dyar's original 

 description. 



In separating his new species from H. pithopoera, Freeman (1944) 

 presented the following diagnosis: "Sheppardi is closely allied to 

 pithopoera Dyar but in this latter species, the apex of the sacculus is 

 not spined as correctly stated by Dyar (1923) and kindly confirmed 

 by Mr. Carl Heinrich, U.S.N.M., Washington, D.C. The anterior 

 arms of the eighth ventral plate of pithopoera are parallel and not 

 divergent from their bases as in sheppardi." 



Dyar erroneously described both of these "key" characters in H. 

 pithopoera. The present author remounted the abdomen and male 

 genitalia of the type specimen of this species since Dyar's preparation, 

 like his drawings, was carelessly executed. Under high magnification 

 the termination of the sacculus, although somewhat pointed, was 

 observed to be spined and the number of spinules was observed to be 

 shghtly variable (two spinules on one sacculus and three at the apex of 

 the other). Dissection of one specimen of "sheppardi" from Maine 

 showed four spinules on one sacculus and six on the opposite one. 

 Furthermore, the eighth sternite of H. pithopoera was identical to that 

 of "sheppardi" with divergent furcations. This re-evaluation has 

 proven H. shep)pardi to be a synonym of Dyar's species. 



For the reasons discussed under H.fumosa, the identification of the 

 larval cases that are recorded below as //. pithopoera is not positively 

 certain. Conceivably, when adequate material from the type locality 

 of H. fragmentella and especially H. coniferella are known, these two 

 insects (or one of them) and H. pithopoera wUl be found to be con- 

 specific.
