INSECTS 



ENTOMOPHAGA 

 Ichneumon-flits^ etc. 



The members of this large section have not been studied in the county. A good number 

 of species are to be found in the miscellaneous drawers of Lepidopterists and others, but they 

 await identification. The following are recorded from Durham in Buckler's Lepidopterous 

 Larva. 



Platylabtus tricmgulatus, Grav., bred by Mr. Robson at Hartlepool from Eupithecia 

 pulchellata, Steph. (the Foglove Pug). 



Paniicui testaceus, Grav., bred from Tethea subtusa (the Olive Moth). 



Meteorus pu/chricornis, Wesm., bred from dgrotis agathina, Dup. (the Heath Rustic Moth). 



Pimp/a graminelLe, Schr., bred from Orgyia antiqua. Linn, (the Vapourer Moth). 



Apanteles astrarcbe, Mar., bred from Lyaena agestis, Hub. (the Brown Argus Butterfly). 



Ichneumon ruficeps, Grav., bred from Selenia illunaria, Hub. (the Early Thorn Moth). 

 The last five were all bred by Mr. Gardner at Hartlepool. 



Pimpla instigator, bred from pupa of Orgyia antiqua, Linn, (the Vapourer Moth), by Mr. 

 Robson of Hartlepool. 



PHYTOPHAGA 



Saw -flies, Wood-wasps, and Gall-flies 



This section of the Hymenoptera has received very little attention in Durham, although 

 the species are often large and showy, and the variety in the shaping of the saw-like ovipositor 

 exceedingly interesting. No local entomologist has yet made a study of these insects, which 

 are entirely absent in the older county lists. A few of the larger forms, which had forced 

 themselves, so to speak, on local lepidopterists, I have found in their boxes of rejectamenta. 



The Great Yellow Sirex or Wood-wasp (Sirex gigas, Linn.) is not uncommon in coal- 

 mines and woodyards, where it has been imported in the pit timber, and it is common in the 

 Shull woods, where it has undoubtedly bred. The Blue Sirex (Sirex juvencus) has also been 

 taken in pine woods on the upper Bedburn in such circumstances as to lead to the reasonable 

 probability of its being county bred. There, also, have been taken on birch these other giants 

 of the section, Cimbex and Trichiosoma . 



The following meagre list contains all the local species that I have been able to verify, 

 but is probably scarcely a tithe of the number inhabiting the county.
