BRITISH ICHNEUMONS. {Habivcryptus. 



from Tortrix roseann by Goureau ; from Devon in May, by Hocking ; 

 from Lynton by S. Edwards ; and from luittle in Sussex, by Bloomfield. 

 Regarding its accelerated metamorphosis, Ratzeburg says a pupa of 

 Tortrix ribeana, in a rolled apple leaf, was found to have an egg extruding 

 on June 4th ; the latter developed into a larva on the 7th, spun,up on the 

 14th, and emerged as a perfect Cryptid on the 24th. Towards the end 

 of May the females may often be beaten from budding oak trees, and 

 throughout the three following months both sexes are frequently swept 

 from the herbage in woods. I possess specimens from Lynmouth, the 

 New Forest, South Wales, Guestling near Hastings, Shere in Surrey, 

 Felden, Treswell Wood in Notts., Delamere Forest, Lyndhurst ; and have 

 found it from the Bentley Woods near Ipswich, in May, to the Blean 

 Woods in Kent, in August. Chitty has found it at Huntingfield in Kent 

 as late as 4th October.

5 . Head coriaceous, with occiput closely punctate ; black, with frontal 

 or vertical and sometimes facial orbits flavidous. Antennae slender and 

 filiform, white-banded ; scape, and flagellum beneath and often basally, 

 ferrugineous. Thorax with two dots on pronotum and another beneath 

 radix flavous ; metathorax sub -pubescent, evenly scabrous throughout, 

 with basal and lateral costae entire, apical costa wanting but apophyses 

 indicated ; spiracles circular. Scutellum punctate, black. Abdomen 

 elongate-ovate, very finely and evenly punctate, and as broad as thorax ; 

 bright red, with three apical segments entirely black ; basal segment 

 glabrous throughout, gradually dilated apically and hardly explanate at the 

 obsolete spiracles ; terebra one-third of the length of the abdomen, with 

 spicula castaneous and compressed towards the apex, its sheaths defle.xed. 

 Legs slender and red, coxae and trochanters black ; hind legs with apices 

 of femora and tibiae and of the tarsal joints nigrescent. Wings slightly 

 clouded, with outer nervure of the areolet somewhat short ; radix pale, 

 tegulae piceous. Length, 6| mm. 



The female of this species may be known by its black scutellum and 

 broadly black anus. It closely resembles H. porrectorius, but has the 

 vertical orbits flavidous-white, no hind tarsal band, the hind femora 

 apically and segments five to eight black, the radial nervure is a little 

 shorter and sub-inflexed. The rather finer sculpture of the less deplanate 

 abdomen is the only structural difference I can detect between this and 

 the last described species. 



S . Head coriaceous, with occiput closely punctate ; black, with vertical 

 orbits alone flavidous. Antennae slender and filiform, with the four 

 flagellar joints ten to thirteen entirely white and the scape somewhat 

 ferrugineous beneath. Thorax with pronotum, a dot at the apices of the 

 humeral lines and two small dots on the disc of the metanotum alone 

 white ; metathorax pubescent, evenly scabrous throughout, with basal 

 costa entire, and the lateral and apical wanting ; apophyses hardly indi- 

 cated ; spiracles circular. Scutellum punctate, white ; post-scuteUum 

 immaculate. Abdomen cylindrical, broadest behind the centre, evenly
