6. CARCELIA PROTUBERANS (Aldrich and Webber), new combination 



Zenillia protuberans Axdbich and Webber, Proc. U. S. Nat. Mus., vol. 63, art. 17, 



p. 15, 1924.— Johnson, List of Now England Diptera, p. 190, 1925.

 logy, pt. !, p. 211,1936. 



This species is considered to be an atypic or aberrant form of 

 Oarcelia malacosomae, which it resembles in some of its characters. 

 The male c; ; male paratype are peculiar in that instead of hi- 



ormally as puparia, they issue the same season. Both 

 specimens are in poor shape, being badly rubbed, with some parts 

 missing, and patched together with glue. The following notes are 

 I ■ d on type material: 



Type. — Head in good condition and agreeing with the description 

 for Oarcelia malacosomae. Thorax badly rubbed; middle and hind 

 legs missing; one wing lacking. Abdomen attached with glue; dor- 

 sum badly rubbed ; sides yellow on segments 1, 2, 3, and a little on 4, 

 extending well up on dorsum and below on the venter. 



Paratype. — Head in poor condition; hairs on the upper side of 

 i he parafacials located with the aid of the binocular high power. 

 Thorax agreeing with 0. malacosomae; midtibia with two median 

 anterolateral bristles; hind tibia ciliate. Abdomen very yellow, ex- 

 tending farther up on dorsum and below on venter than in the type 

 (fourth segment included). 



Aldrich and Webber describe the abdomen as being "mostly yel- 

 low excepting a black vitta on the dorsum and a similar one on the 

 ventor." The amount of yellow color is far beyond that described 

 for Oarcelia malacosomae. in which the male abdomen is broadly 

 black on the dorsum, with the sides rufous. 



Type and paratype locality. — Rockingham, Vt. 



Type.— Male, U.S.N.M. No. 25G99. 



Host. — Malacosoma disstria Hiibner. 



Remarks. — The two male specimens were reared at the Gypsy Moth 

 Laboratory from material collected at Rockingham, Vt,, June 12, 

 1915, by J. J. Culver, the flies issuing July 23-25, 1915.
