PERITHOUS Holmg. 



P. pleuralis Cress. Nyack, N. Y. (Zabriskie), and sure to occur in North 

 Jersey.

 (Jn) ; Manumuskin X, 8-21 (Dke) ; reared from "Liopus variegatus." 



E. mesocentrus Grav. (rex Kriech). A European parasite of "Coccyx 

 resinana" introduced into New York State (Ashm), and which prob- 

 ably occurs in New Jersey as well. 



E. tuberculatus Fourc. Probably introduced from Europe, where it is 

 parasitic on a variety of wood-boring coleopterous larvae, one of 

 which, "Cryptorhynchus lapathi," also occurs in New Jersey. Also 

 infests lepidopterous larvae. 



MEGARHYSSA Ashm. (THALESSA Holm.)

M. lunator Fab. Throughout the State, hardly less common than "atrata."' 

 Parasitic on "Tremex columba" These species are the common, long- 

 tailed "Ichneumons," often found with their bristle-like ovipositors 

 inserted into trees; hence generally suspected of being wood-borers.

R. persuasoria Linn. This, with its variety "albomaculata" Cress., no 

 doubt occurs throughout the State. It has been reared from "Mono- 

 hammus scutellator" and "confusor," and in Europe is parasitic on 

 species of "Sirex."
