Hubbard reared specimens from Hijppodamia convergens (Insects affect- 

 ing the Orange, Division of Entomology, p. 74). As far as observed 

 this species, the sole Korth American representation of the genus, in- 

 fests only Coccinellid larvae, but a congeneric European species has 

 been found to prey upon Galeruca of the family Chrysomelidae. 



Eupelmiis cyaniceps Ashm. was reared from the seed pods of the 

 False Indigo {Amorpha fruticosa) which were inhabited exclusively by 

 Bruchus exiguus Horn. Adults issued at Washington, D. C, during 

 the early part of October. This insect is by no means rare and it seems 

 a little singular that it, or an allied species, has not been recorded from 

 the congeneric species, the Pea and Bean Weevils. 



Another species of Eupelmus issued from apple twigs from which 

 was also reared the injurious Fruit Bark-beetle, Scolytus rugidosuSy 

 the only other species bred. Port Eichmond, Staten Island. This 

 species seem to be extremely rare. 



Catolaccus tylodennce Ashm. A pair of these parasites, male and 

 female, were reared in September from the pupal chambers of Tylo- 

 clerma foveolatum^ but whether from the larvae or pupae could not be 

 ascertained. In order to effect their exit they were obliged to cut 

 through the stem which is of about the consistency of the average per- 

 ennial of the same size, and about 0.10 inch thick at the point of exit. 

 The cells of each could be readily distinguished by the exit holes, that 

 of the male being appreciably smaller. District of Columbia. It is 

 quite possible that this species may also parasitize the noxious Tylo- 

 derma fragariWj or Strawberry Crown-borer.

Anoxus chittendeni Ashm. was bred from Poly]3orus, a genus of tree 

 fungus, inhabited by Cis fuscipes^ and is without doubt parasitic on this 

 beetle, since no other insects were present at the time of this rearing, 

 Ithaca, N. Y. 



Ceplialonomia hyalinipennis Ashm. was reared under precisely similar 

 conditions to the above from twigs of Fig (Ficus indica) growing on the 

 grounds of the Department of Agriculture. These twigs were infested 

 exclusively with the little Scolytid, Hypotlienemiis erudittis, which with 

 the parasite occurred in abundance in burrows in the pith in October. 



Quite a number of other species have been reared from wood, but 

 under such circumstances that it has been found impossible to deter- 

 mine the host. Doubtful cases have not, therefore, been considered/ 

 and I feel reasonably certain that the rearings here mentioned are 

 worthy of record, although the host insect has not been, in all cases, 

 identified with absolute certainty. 



In most cases the parasites under observation were kept under iDrac- 

 tically normal conditions, and the breeding dates given are therefore 

 nearly as in nature.
