BRACONID^. 



Bracon simplex Cress. The cocoons of this species were of qnite 

 common occurrence in the nests constructed by, and characteristic of, 

 Rhagium lineatum under the bark of white and pitch pine trees, within 

 which the beetles undergo their transformations. Parasites reared at 

 Ithaca, I^. Y., in confinement under nearly natural conditions, issued 

 from May 19 to June 11, and specimens were captured Hying about 

 pine logs at a later date. This species has been also reared in the 

 Division from an unbred Cerambycid under oak bark, as recorded in 

 Insect Life, vol. ii, p. 348, and by Mr. A. D. Hopkins from wood of 

 Beech and Spruce infested by Cerambycidai and Buprestidaj (1. c, vol. 

 IV, p. 256). 



Bracon eurygaster Brulle was bred from small branches of Quince 

 that had been amputated by IJlapMdion viUosum Fab. the only other 

 species reared fiom this wood. Also reared under similar conditions 

 by Mr. Hopkins, from elm wood infested by an unknown Longicorn 

 (1. c, vol. IV, p. 257). South Woodstock, Conn. 



Bracon erythrogaster Brulle was reared from hickory wood infested 

 almost exclusively with Cyllene picta. Specimens were also taken 

 under the bark of Oak where they were probably parasitic on some 

 other common Longicorn. Ithaca, IS". Y. 



Doryctes radiatus Cr. was bred from flattened cocoons similar to those 

 of Bracon found under the bark of newly felled hickory wood infested 

 with CyUene picta, on which species it is doubtless parasitic. Imagos 

 emerged in June. Specimens were also taken in the field. May 26. 

 Ithaca, N^. Y. 



Ca'Hophanes dinoderi Ashm. MS. bred out from some pieces of dead 

 oak wood together with thePtinid, IHnoderus punctatuSj the only other 

 species found. The beetles were extremely abundant; the parasites 

 were rare. Date of emergence not noted. Flatbush, L. I. 



Camophanes utiUs Cr. was reared from larvae of Liopus cinereus Lee, 

 found boring the twigs of Locust {Bohinia pseudacacia). All stages 

 were taken April 21, one adult already dead. The first pupa was seen 

 JNIayS; this prepared to transform May 22 and the adult insect was 

 found May 25. One larva transformed to pupa as late as June 10. 

 ]\Iany of these Cerambycid larvse were parasitized. Ithaca, N. Y. 



Uelcon dcntipes Brulle was bred from chestnut wood infested by a 

 small Longicorn, supposed to have been Callidium a'reiim, also from 

 wood from which were reared Rliopalophora longipes a-id Curius denta- 

 fns. These Longicorns belong to the same sub-family, the Ceramby- 

 cinw and the Hymenopteron might be ])arasitic on all three species. 



Cenoca'lins rnbriceps Prov. is an external parasite of Liopus cinereus. 

 It was reared from the latter found breeding in the twigs of Locust
