282 PROCEEDINGS OF THE NATIONAL MUSEUM vol.88 



slightly nearer anterior than posterior margin of epipygium, placed 

 in an indistinct setose area, which is bounded mesad and cephalad by 

 a vague carina; apex of ovipositor sheath provided with moderately 

 long ventral setae. 



Male: 5.5-8.5 mm. Antennal scape (fig. 8, n) expanded near base; 

 combined widths of compound eyes equal to interocular width at level 

 of antennal bases ; metafemur with a blunt inner tooth ; petiole twice 

 as long as wide. 



Type locality. — "North America." 



Type. — Chalcis No. 13, Fabricius collection, University of Kiel, 

 Kiel, Germany. Type much broken, moldy; sex not discernible. 

 Specimens compared with this type by Dr. Olaw Schroeder. Syno- 

 nyms: hracata Sanborn, Boston Society of Natural History (com- 

 parisons made by Dr. Richard Dow) ; hracata coaequalis Cresson, 

 1788, Academy of Natural Sciences of Philadelphia; Carolina Ash- 

 mead, 41181, U. S. National Museum ; secunda Girault, 20750, U. S. 

 National Museum. 



This large, conspicuous species is so variable that it is not sur- 

 prising that it has been described several times. The type of S. Caro- 

 lina Ashmead is somewhat broken but shows no differences in either 

 color or structure from specimens compared with the type of C. 

 nigricomis. Dr. Richard Dow, of the Boston Society of Natural 

 History, informs me that the type of C. hracata Sanborn lacks the 

 abdomen but is identical with the specimens of nigricornis sent. 

 The type of D. secunda Girault is considerably broken, but the re- 

 mains show no valid departure from the typical nigricornis. All 

 the references to maculata enumerated above were derived from 

 Walker's record of what he supposed to be maculata Fabricius from 

 New York. Dr. Ch. Ferriere, of the British Museum, has kindly 

 located Walker's specimen for me, and he states that this specimen, 

 although somewhat broken, can be identified as nigricomis. Chalcis 

 maculata Fabricius was described from South America, and Ash- 

 mead ^^ placed it in his genus Tetrasmicra; it is possible that he had 

 seen the type. 



Hosts. — Parasa indetermina Boisduval, Adoneta spirmloides Her- 

 rich-Schaeffer, Limacodes sp. (Lepidoptera, Limacodidae) . 



Distribution. — Connecticut, Illinois, Indiana, Louisiana, Maryland, 

 Massachusetts, Nebraska, New Hampshire, New Jersey, New York, 

 North Dakota, North Carolina, South Carolina, South Dakota, Texas, 

 Virginia.
