PiMPLA INQUISITOR Say. 



This species has been twice bred 

 from Orgyia leucostigma ; and an 

 adult was noticed by Mr. H. Garman, 

 at Normal, 21 June 18S3, "attempting 

 to sting," a full grown Orgyia larva. 

 Another was bred from what was sup- 

 posed to be a phalaenid larva on apple 

 in 1885 — the host being collected 10 

 June, and the adult parasite emerging 

 29 June. The species has also been 

 taken in the field at various times — 

 among others at Urbana 13 June 1S85, 

 and 3 Oct. 1SS7, and at Normal 13 June 

 1883. 



PiMPLA ALBORiCTA Cresson. 

 A single specimen of this beautiful 

 little insect was bred at Normal, 11 

 Aug. 1 884, from an unknown lepidop- 

 terous leaf-rolling larva on sycamore 

 {Platamis). 



Glypta VULGARIS Cressou. 

 Two specimens of this species were 

 bred during the summer of i8S4from 

 larvae of Botys itiseqiialis collected 

 in June on thistle heads. Another 

 emerged 24 July 1883, from a chrysalis 

 in the fold of a strawberry leaf collected 

 at Normal. Others were taken in the 

 woods in Tazewell Co. 14 Aug. 1S83 ; 

 and on apple trees in McLean Co., 3 

 May 1884. 



Glypta simplicipes Walsh. 

 A single specimen of this insect was 

 bred 8 August 1884, from the cocoon 

 of some leaf-roller on apple — just what 

 species I cannot say. Both Teras mi- 

 nuta (Robs), and Cacoecla rosaceatia 

 Harr., were present in the field of 



young apple trees from which the 

 cocoon was taken. 



Tkogus obsidianator Brulle. 

 The only bred specimen of this 

 species emerged 13 June 1885, from a 

 lepidopterous cocoon supjDosed to be 

 that of Pyrrharctia Isabella. Other 

 specimens were collected in McLean 

 Co., 16 June and 13 July 1882, and 26 

 June 1885. 



Trogus exesorius. 



This insect seems especially to attack 

 the larvae of species of Papilio. Dr. 

 A, S. Packard has noted^ that it infests 

 P. asterias.^ P. troihis., P. tur7tus.i P. 

 ajax and P. luarcellus., and Mr. Fred- 

 erick Clarkson has also bred it from P. 

 troihis^ and has made the interesting 

 observation that the point of exit of the 

 parasite is "the same in every case, viz., 

 on the right or left side, about midway 

 of the thorax, at the widest part.'^ 



Four larvae of Papilio asterias were 

 collected on parsnip, 23 July 1885, at 

 Champaign. One specimen pupated 27 

 July, another 28 July, another 30 July. 

 The date of pupation of the fourth larva 

 was not recorded, but the first butterfly 

 emerged 5 August, and a second one 17 

 August. A live Trogus was found in 

 the cage 25 August, and another emerged 

 5 Sept. Hence it appears that the 

 parasite remains in the pupa state some»- 

 what longer than its host. 



Other specimens of this insect were 

 collected at Bloomington 23 Sept. 1879 ; 

 and at Champaign 8 July 1887, tlie latter 

 being taken in the woods.
