lepidopterous insects, it may well be regarded as a very beneficial form. 

 Another insect belonging to the same genus, P. annulipes BruUe, has 

 been recorded as a parasite of this species, by Bruner. In addition to P. 

 pedalis, Dr Fernald reared a few examples of Theronia melano- 

 cephala BruUe from cocooas. A variety of Apanteles congregatus^ 

 rufocoxalis Riley, was bred from tne larvae by Dr Lintner. Dr Fitch 

 reared from the cocoons a parasite to which he gave the name^' of

Cleonymiis cllsiocampae. Dr Howard states that Mr Ashmead has 

 referred this species to the European Dibrachys boiicheainis Ratz., 

 which is not a primary parasite, as Dr Fitch supposed his species to be. 

 Telenoj?ius clisiocampae Riley, has also been reared from the eggs of 

 this and another species of Clisiocajnpa i^Insect life. 1891. 4:123). 

 But one parasitic fly, Frontina freiichii Williston, has been reared from 

 the tent caterpillar, according to Coquillett. 



A number of predaceous insects attack the larvae. Several species of 

 large ground beetles are said to prey on the caterpillars, among them 

 being Calosoma scrutator Fabr. As others of the same genus attack 

 Clisiocampa disstria Hiibn., it is probable that they would not discriminate 

 between the larvae of these closely related forms. Owing to the extend- 

 ed studies of Mr Kirkland, we know more fully the habits of the genus 

 Podisus, several species of which attack the tent caterpillar. The fol- 

 lowing have been observed preying on C. amerirana: Podisus placidus 

 Uhler, P. modestus Dallas, P. serieventris Uhler, and Diplodus luridus
