Anthrax hypomkIvAS Macquart 



Anthrax hypomelas Maequart, Dipt. Exot., Vol. 2, Pt. 1, 1838, p. 76. 



Pupa. — Length, 14 mm. Pale testaceous, slightly shining; thorns 

 on head and on abdomen dark brown. Upper pair of cephalic thorns 

 contiguous for two thirds of their length (PI. LXXXI, Fig. 22), lat- 

 eral thorn flattened, simple, the pair on median line near lower margin 

 contiguous, a small fine hair on each side of the latter pair, a longer 

 hair on each side of the upper pair of thorns and another above the 

 base of each thorn (Fig. 20). Thorax without protuberances; a pair 

 of small fine hairs above the base of wing cases, and another pair on 

 each side of median line about middle of thorax. Abdomen similar to 

 that of A. lateralis, differing only in having apical armature as in Fig- 

 ure 18, the median tooth having more the appearance of a small proc- 

 ess on base of upper one than of a separate tooth, or occasionally 

 almost indistinguishable. 



As mentioned under the previous species, hypomelas has been re- 

 corded by Riley and Howard, but the figure given in the paper is not 

 clear enough in detail to permit of its specific characters being recog- 

 nized although the general habitus is unmistakable. 



The specimens of Jiypoinelas pupae that I have seen include one, 

 without label data, obtained from the Ohio Agricultural Experiment 

 Station, Wooster, Ohio, with the statement that it had been reared at 

 Wooster in 1907, and two in this Laboratory. 



The pupal exuvia last referred to are those of specimens reared 

 from Feltia jaculifera at Urbana, 111. The larvae of the moth were ob- 

 tained June 8, 1 90 1, and the parasites emerged September 14 of that 

 year from the pupae of the host. 



Specimens of the imago are in the collection here from the follow- 

 ing localities: Havana, 111., September 5, 1905; Urbana,, 111., Sep- 

 tember 21, 1890 (C. A. Hart); Grand Forks, N. Dak., July and 

 August, 1890, (Miss M. J. Snyder) ; and Westville, N. J., September 

 9, 1901.

Larva. (PI. LXXXI, Fig. 10). — Length, 22 mm. White. Head 

 brown, black on posterior margin of dorsal surface. Dorsal sclerite 

 with a long slightly curved hair on each side one third from posterior 

 margin; dorsal and ventral sclerites separated laterally by a rather 

 broad membranous stripe, near the anterior extremity of which is a
