, THE CHALCIDOID GENUS PERILAMPUS. 63 



a species from Chrysopa at Utica, Miss., tWs record being the one 

 referred to in liis Monograph of the Chalcidoidea. 



In a paper entitled ' ' A list of the parasites known to attack North 

 American Rhynchophora,"^ Mr. W. D, Pierce records Perilampus as a 

 parasite of the cotton boll weevil {Anihonomus grandis Boheman) in 

 cotton squares in Louisiana. Mr. Pierce in a recent letter regarding 

 this record states that it is open to question. A cotton square from 

 wliich a wee\dl had emerged forms an excellent retreat for another 

 insect that might be inclined to secrete itself in this manner. It may- 

 be that in this case a Chrysopa larva parasitized by Perilampus 

 crawled into the square to pupate and from this the Perilampus 

 emerged later. That Chrysopa is prone to do just this thing is a 

 well-known fact. Dr. Howard described the chalcidoid parasite 

 Isodromus iceryse as a parasite of the scale Icerya. He later found 

 that Isodromus was instead a parasite of Chrysopa, which in this 

 instance had crawled beneath the Icerya scale, through which the 

 Isodromus later emerged. 



In 1897 Mr. W. F. Fiske reared a single specimen of Perilampus 

 hyalinus from the cocoon of Limnerium fugitivum, Say as a parasite of 

 Hyphantria. This fact was recorded in his paper on the parasites of 

 the American tent caterpillar,^ and probably constitutes the first 

 pubhshed record of Perilampus as a secondary parasite on Hymen- 

 optera. 



Quamtance and Brues in their study of the cotton bollworm^ 

 found this species to be a rather uncommon parasite of Microplitis 

 nigripennis Ashmead, a braconid parasite of Heliothis ohsoleta Fabri- 

 cius m Arkansas and Texas. 



Dr. L. O. Howard, m a paper entitled "The biology of the hymen- 

 op terous insects of the family Clialcididse," ^ makes the statement 

 that Perilampus has been reared from Tachmidae, but none of the 

 details of the rearing was given. Dr. Howard, hi a recent letter m 

 regard to this, says that he is unable to find any record upon which 

 this statement was based, but that he is of the opmion that it was 

 reared from tacliinid puparia m the office of the Entomologist at 

 Washmgton prior to 1892. This is the first published record, so far 

 as we are aware, of Perilampus as a parasite of Diptera. 



Prof. M. II. Swenk ^ records having reared Perilampus hyalinus 

 from a sarcophagid which in turn was reared from Melanoplus hivitattus 

 Say.
