140 HYMENOPTERA. 



19. Glauraspidia subtilis. — Eucoila subtilis, Dahlb. Sk. 



Hym. Fn. p. 32. Glauraspidia microptera, Thorns. 

 p. 401. Found in Swithland Wood, Leicestershire ; 

 also taken by Mr. Walker. Forster separates \liis 

 insect from Cothonaspis micropterus, Hart. ii. 201, 

 with which it was united by Thorns., and forms of 

 the latter the new genus Apistophyza. 



20. PsiLODORA BoiENii.— Cothonaspls Boienii, Hart. ii. 200. 



Taken near Milford Haven. Not common. This 

 and the following are distinguished by having a 

 fuscous blotch upon the wings. 



21. PsiLODORA MACULATA. — ? Figites syrphi^ Newm. Ent. 



Mag. ii. 515. Eucoila crassinervis, Dahlb. Sk. 

 Hym. Fn. n. 20 (jiec Eucoila crassincrva^ Westw.) 

 Eucoila Guerini, Dahlb. Onych. och Callasp. pi. ii. 

 f. 8. Cothonaspis maculatus, Hart. ii. 201 ; Eucoila 

 maculata, Gir. p. 134 ; Thoms. p. 405. The doubt 

 attaching to the first name, and the sketchy nature 

 . of the indications given by Dahlbom, render it advis- 

 able to prefer the name maculata. 



22. Aglaotoma codrina. — Cotho7iaspis codrinus,}iart. iii. 



357 ; Gir. p. 146. 



23. Trtbliographa scutellaris. — Cothonaspis scutel- 



laris, Hart. ii. 200 ; Eucoila scutellaris, Gir. p. 140. 

 Figites foveator^ Dahlb. Sk. Hym. Fn. p. 30. I am 

 almost sure that this is Westwood's Eucoila crassi- 

 nerva, the original type of the genus Eucoila^ not- 

 withstanding Dahlbom's opinion to the contrary. If 

 this be so, the name Euccela should be reserved 

 for it. 



24. Trtbliographa diaphana. — Cothonaspis diaphanus^ 



Hart. iii. 356.
