INTRODUCTORY PAPERS ON ICHNEUMONID. 
By Joun B. Bripeman anp Epwarp A. Fircu. 
No. Il].—CRYPTID (continued). 
Two species are added to the sixty included in Marshall’s 
catalogue,—C. antennatus, Bridgm. (see Trans. Ent. Soc., Lond., 
1881, p. 158), and C. amenus, Gr. (Entom. xii. 55); and 
C. dubius, Tasch., has lately been bred by Mr. T. Wilson from 
rose sticks, where it is a parasite of Hmphytus cinctus ; whilst 
C. elegans, Desy., is not considered as a variety of carnifex 
(Trans. Ent. Soc., Lond., 1881, p. 153); neither is C. ornatus, 
Gr., considered a variety of tricolor (Trans. Ent. Soc., Lond., 
1882, p. 148). Hitherto the species commonly bred from the 
sawfly (J'richiosoma) cocoons has in this country been considered 
identical with the true C. migrator, so. commonly bred from the 
cocoons of Bombyces and other Lepidoptera; the former is 
C’. cimbicis of Tschek. (Verh. z.-b. Gesell. Wien., xx. 412). 
Everywhere the very closely-allied C. migrator, ieubitor, fumi- 
pennis, cimbicis, &c., have been much mixed; it is hoped the 
distinctions given in the above tables will help to correct this, 
but it is necessary that all bred specimens should be closely 
examined. ‘The species included under hostilis and porrectorius, 
’ by Marshall, are also much confused by various authors. 
C. attentorius is figured in Schiiffer’s ‘Icones’ (pl. 157, fig. 7), 
C. minutorius is figured by Panzer under the name of rubricator 
(pl. 84), C. seticornis (var. of Diane) is figured in Ratzeburg’s 
‘Die Ichneumonen’ (vol. i., p. vi., fig. 10), and Curtis beautifully 
figures the female of C. signatorius, under the name of bellosus, on 
his plate 668. On plates 6 and 41 of Vollenhoven’s ‘ Pinaco- 
graphia,’ thirteen species of Cryptus are well figured, including 
many details; nine of these are British. C. antennatus is badly 
figured in Trans. Ent. Soc., Lond., 1881, pl. viii., figs. 10, 10a. 
M. Boudier well illustrates the life-history of C. migrator in the 
plate accompanying his ‘Observations sur les habitudes de 
larves d’Ichneumon vivant aux dépens de la chenille du Bombyx 
du chéne” (Ann. Soc. Ent., France, v., pp. 357-365, pl. viii.). 
According to Boudier’s observations the male Crypti emerged in 
May, 1834, from the smaller hole in the B. quercus cocoon (which 
was collected in October, 1853), and the eleven ichneumon
