OF WASHINGTON. 151 



(21) Rhogas geometrce, Ashm. Bred from a geometric! 

 larva (probably Anisopteryx) from Arlington, Mass. ; parasite 

 pupated 20 June, 1884, and emerged 8 April, 1885. (612.) 



(22) Bracon charus, Riley. Known to be a parasite of 

 buprestid and cerambycid larvae, this species was bred from 

 decaying bark of hiercus, where its host was apparently Eucrada 

 humeral is. Cambridge, Mass., 1885. (671.) 



(23) Habrobracon gelechice, Ashm. From a noctuid larva 

 living among the buds and blossoms of Solidago ; Cambridge, 

 Mass., July, 1883. (429.) 



(24) Apanteles acronyctce, Riley. From a larva of Apatela, 

 supposed to be that of A. vulpina, inN. H., Sept., 1892. (1032.) 



(25) Apanteles congregatus, Say. I have obtained this spe 

 cies from the following sphingid larvae : Thyreus abbotii, at 

 Cambridge, Mass., about i July, 1879, and about 26 July, 1882 ; 

 at the latter date the A. congregatus had four kinds of hyper- 

 parasites, which are mentioned under their respective species. 

 Philampelus pandorus, at Cambridge ; the parasites emerged 

 about i Oct., 1882. Ampelopkaga myron, at Cambridge; the 

 parasites emerging 19 Aug., 1882 ; also, several rearings in 

 N. H., among which emergences occurred 12 Aug., 1890, and 

 about i Sept., 1892. Ampelophaga versicolor, in N. H. ; 

 emergences 16 and 25 Aug., 1892. Sphinx chersis (= S. cin- 

 erea),at Cambridge; emergences, 17 Sept., 1882, 4 Aug., 

 1883, and 21 May, 1884. The last mentioned lot of parasites 

 hibernated as pupas, having pupated n Sept., 1883. 'Dolba 

 hylccus,* in N. H. ; emergence early in Sept., 1895. 



(26) Apanteles smerinthi, Riley. From larvae of Smerin- 

 tlius geminatus, in N. H. ; in some cases the parasites hibernate 

 in their cocoons. (1020, 1136.) 



(27) Ap anteles xy Una, Say. From larva of Ellema harrisii, 

 in N. H. ; parasites pupated late in August and emerged early 

 in Sept., 1895. (1121.) 



(28) Apanteles euchcetis, *Ashm. From larvae of Euchcetes 

 egle, in N. H. The larvas of the parasite came from the moth- 

 larva, and pupated in a mass beneath the hairs of the latter ; 

 both pupation and emergence occurred in Aug., 1895. (1125.) 



(29) Apanteles murtfeldtcz, Ashm. From a geometrid larva 

 that fed on Rubus canadensis, at Cambridge, Mass. ; parasites 

 pupated 2 July, 1883, and emerged five clays later. (450.) 



* These parasites were from the larva of D. hyloeus [!], which feeds on 

 Ilex verticillata, and not from the larva well described by Mr. S. H. 

 Scudder (Psyche, 1877, v - 2 > P- 77)> which I have proved by rearing to be 

 that of Sphinx gordius, which is common on Comptonia asplenifolia in 

 N. H.,and which I have found in Cambridge, Mass., feeding on S-pircea 

 salicifelia.
