 the first, the third one-half longer, stouter, the fourth nearly twice

Winnertzia aceris Felt

The white larvae of this species occur singly or in small groups 

 under the thin, decaying bark of sugar maple. The adults are 

 closely allied to both W. calciequina Felt and W. pcet i na t a 

 Felt. The male of the former has heavy circumfili extending to 

 the basal fourth of the enlargement, while in this species the basal 

 portion of the circumfili reaches only to the distal third of the en- 

 largement as in W. pectinal a. The chitinization o\ these struc- 

 tures is much weaker ihan in the lasi named spceies, the basal en- 

 largement is more globose and cylindric and there are differencesin 

 the genitalia. Detailed descriptions are given in the above citation.
