Dec, 1909.] GiRAULT : A New ChALCIDOID FROM ILLINOIS. 171 



Antennje i2-jointed, filiform, longer than the body, the funicle joints not 

 differing abruptly in size, but gradually shorter distad. Pedicel smaller than 

 in the female, obconic, its sides rounded or convex as seen in profile, wider 

 than the proximal funicle joint and not more than half its length ; joints 1-8 

 of the funicle subequal, long, cylindrical, longitudinally carinate, gradually 

 becoming narrower distad, the carinations forming acute points at the distal 

 ends; joint 9 of the funicle slightly shorter, the same; the distal or club joint 

 a third shorter than either of the joints i to 8, slightly narrower, carinate and 

 with a slight nipple at the center of its extremity. Scape slenderer than in 

 the female. Antennje with very fine, moderately close hairs.

Described from 5 males and 3 females reared June 26 (2 J*'s, i J 

 types), 27 ( I J*, I 5), 30 ( I 5) and July 4 (2 J^'s), 1909, at Centralia, 

 Illinois, from the eggs of the common weevil Tyloderma foveolatum 

 (Say) in the stems of the weed Ginothera biennis Linnaeus. The 

 parasite is solitary as shown by dissection, the body of its pupa filling 

 nearly the entire cavity of the host egg. It is not rare in this 

 vicinity. 



The foregoing descriptions were made from recently killed speci- 

 mens, the coloration and sculpture, shape of the head, abdominal 

 segments and so on from unmounted ones, the antennae, legs and 

 wings being described from specimens mounted in balsam. It should 

 be stated, therefore, that shortly after death, in tag-mounted speci- 

 mens, the body begins to shrivel, the face shrinks and caves in mak- 

 ing the vertex acute and placing the cephalic and lateral ocelli in 

 different aspects, the thorax contracts somewhat and other parts are 

 so warped that it is impossible to make out true relationships after 

 they have been dead several hours. 



Anaphes conotracheli Girault, a species closely related to the 

 type species just described, belongs to Anaphoidca.
