NOTES ON DIPTERA IN THE FORTH DISTRICT 51 



12. D. chorea, Mg. I have taken this common species at 

 Miisselburgh, Polton, Callander, etc, 



13. D. trinotata, Mg. $, Arniston, rgth August 1905. 

 (J.W.) agrees with recent Continental descriptions of this species, 

 and the prepared hypopygium is quite like Mik's fig. in Verh. k. k. 

 Zool. Bot. Ges., Band 31 (1881). I am not clear if it is specifically 

 distinct from didynia, Mg. Mr Edwards tells me De Meijere 

 regards it as a dark var. of that species. 



14. D. dumetorum, Mg. 2 $.,2 ?, Polton, 6th August 1906; 

 $, Callander, 3rd August 19x7. 



15. D. morio, F. ?, Callander, 3rd June 1916. 



16. Atitocha opalizans, O.-S.- ?, Musselburgh, 24th July 1906. 



17. Enipeda 7iiibila, Schum. Polton, September 1906, and 

 June 1915; c? , 3 ? , Bavelaw Burnside, 2nd June 1904 (J. W.). 



18. AcyphoJia maailata, Mg. Both sexes, Musselburgh, June, 

 July, 1906-7; Polton, June 1915. 



19. Molophilus murinus, Mg. Polton, June 1915; Callander, 

 3rd June 1916. 



20. Rhypholophus nodulosus, Mcq. As pointed out by Verrall 

 we have two species under this name. They are well distinguished 

 by the antennae and the $ hypopygium. One, I have from Bavelaw, 

 2nd June 1904 (J. W.), and Callander, 7th June 1916; the other 

 (rarer in my experience) with a tuft of long yellow silky hairs on 

 the hypopygium below, from Polton, June 19 15, and Callander, 

 June 1916. 



21. R. simiHs, Staeg. Polton, 6th August 1906. The pre- 

 pared hypopygium agrees with Lundstrom's fig. in Diptera 

 Finlands, 19 12. 



22. Erioptera tcznionota, Mg. 9) Musselburgh, 5th July 

 1906; 2 (^ , Callander, 3rd June 1916 (dark). 



23. Idioptera trimaculata, Zett. -$ , Callander, 7th June 1916.
