There cannot be a greater proof of the general neglect of the 

 Hymenoptera in this country, than the fact that this numerous 

 and interesting genus of insects, which has been described and 

 published by Latreille upwards of twenty years, has not been 

 even recorded as British in any of our works, excepting the 

 *' Guide." Nineteen species are there named, and in Mr. Ha- 

 liday's collection alone I have seen fifteen others undescribed. 



The remarkable margin to the body beneath, forming a 

 sharp edge, is common to Scelio, Sparasion, Teleas and Pla- 

 tygaster. From these genera Teleas is distinguished, by having 

 a costal instead of a subcostal nervure, which terminates in a 

 short branch in the superior wings. In Ceraphron the large 

 stigma to the wings will characterize the greater portion, and 

 the whole are separated from Teleas by their 5-jointed maxil- 

 lary palpi and 11-jointed antennae. 



From Mr. Haliday's observations it appears that the genus 

 may be thus divided : 



I. With a punctiform stigma, situated beyond the middle 



of the wing. 



1. T. varicornis Hal. — Is found in sandy places. 



2. T. elatior Hal. — Brit. Ent. pi. 333. — Taken in June by 



Mr. Haliday on marshy ground. 



3. T. lotus Curtis. 



4. T. clavicornis Lat. — In sunny gravel-pits. 



5. T. longipes Curt. 



6. T. Ephippium Hal. — Found in August. 



7. T. flavipes Hal. 



8. T. femoratus Curt. 



9. T. niger Curt. 



10. T. fumipennis Curt. 



11. T. fuscipennis Walk. 



12. T. minutus Curt. 



13. T. iEthiops Hal. 



II. With a longer and angulated nervure branching off 



from the costa near the middle. 



14. T. ater Curt. — This may be only a black variety of the 



next. 



15. T. metallicus JZaZ.— Has been taken by Mr. Haliday 



amongst Junci on the banks of stagnant pools, and in 

 the water, July 31st; and by Mr. F. Walker at 

 Southgate on Lime-trees in September, and on the 

 banks of ponds and brooks just above the water in 

 October. 



III. Apterous. 



16. T. longicornis Curt. 



17. T. pusillus Ctirt. 



18. T. Pulex Hal. 



19. T. brevicornis Hal. 



20. T. parvulus Hal. 



The plant is Arenaria serpyllifolia (Thyme-leaved Sandwort).
