species as it now stands. The specimens from the Ber). Zool. Mus., 

 described by Taschenberg, were found on Herpestes ichneumon, in Egypt. 

 The same or a nearly related Herpestes is found in Socotra, and as its 

 habits resemble in many ways those of the Mus, it is very easy to see 

 how the same species of flea might occur on both. 



Pulex simulans, n. sp. 



Two specimens of this flea, taken from opossum (Didelphis 

 virginiana), were sent to me by Mr. L. O. Howard, from the U. S. Dep. 

 of Agriculture collection. Though distinct, yet it is very closely related 

 to P. irritans, and might easily be confused with that species.

1l\\\s nearly cosmopolitan flea I have received from Mr. S. C. Ban- 

 dore, of Lakeside, Cala., and through Mr. L. O. Howard, from Azura, 

 Cala., at both of which localities it is common.

NOTES ON SOME REARED HYMENOPTERA, LARGELY 

 PARASrnC, AND CHIEFLY FROM OHIO. 



BV F. M. WEBSTER, WOOSTER, OHIO. 



Elachistus ohioensis (MS.), Ashmead. — Reared from pupge, in which 

 stage it probably passes the winter ; found November 7th, within the 

 shells of beech-nuts, the kernels of which had been attacked and eaten by 

 some kind of larva which had burrowed out these kernels, leaving only a 

 mass of excrement. A hole in tlvj sliells indicated an attack similar to 

 that of some species oi Balanhtus, though, as I found no larvae of them, it 

 was impossible to learn their exact nature. Locality, Wooster, Ohio. 



Cirrospilus flavicindus, Riley. — This was described in Lintner's 

 First Report as being reared from Bucculatrix pomifoliella, Clemens, in 

 Missouri, and also New York. My rearings were from Aspidisca 

 splendoriferella. Clem., the cocoons of which were collected near Cleve- 

 land, Ohio. 



Aphidius chenopodiapJiidis (MS.), Ashmead. — This was reared from 

 an Aphid found on the leaves of Chenopodium album, Linn., collected in 

 the vicinity of Cleveland, Ohio, June 29th, 



Isocratus vulgaris. Walker. — This and an undetermined Apanteles 

 were reared with the species next following.
