IGG [May. 



is readily distinguished by the large yellow upper appendages of the 

 hypopygiuni. A male presented by Dr. Sharp to the British Museum. 



4. — Tkichonta subfusca Lundstr. 

 1 J, 1 ? . Logie. Elgin, 1913 (F. Jenkinson). In the Cambridge 

 Museum. 



5. — Trichonta vernalis Landrock. 

 (Zs. wiss. Ins.-biol. 1913, p. 88). 

 1 c?, Felden, Herts., 23.ii.1899 (A. Piffard). In the British 

 Museum. 



6. — Rhymosia tarnanii Dzied. 

 1 (^ , Logie, Elgin, 1913 (F. Jenkinson). In the Cambridge 

 Museum. 



It may be mentioned here that Rhymosia macidosa Mg., may be 

 re-instated in our list, as I have examined a male specimen collected 

 by Mr. F. Jenkinson at Cambridge. The species identified by Walker 

 as Mycetophila maculosa Mg. was really B. fenestralis, so that the 

 present I'ecord practically amounts to a new one. 



7.— EXECHIA LIGULATA Luudstr. 



(Ann. Mus. Nat. Hung., 1913, p. 312). 



Two males in the British Museum from Lelant, Cornwall, 22.vii.1912 

 (Lt.-Col. Terbury), and New Forest, 25.x. 1908 (F. C. Adams); a 

 third in the Cambridge Museum from Crowborough, Sussex, 5.viii.l906 

 (F. Jenkinson). 



8. ExECHIA MEMBEANACEA Ltindstr. 



A male from Crowborough, 22. iv. 1914 (F. Jenkinson), is in the 

 Cambridge Museum. 



9. — Mycetophila bialorussica Dzied. 



Two males from Logie, Elgin (F. Jenkinson), 4.ix.l909 and 1913, 

 one in the Cambridge Museum, one presented to the British Museum 

 by the collector. 



This species is peculiar in having the front tarsi of the male 

 thickened ; otherwise it bears some resemblance to M. himaculata. 



10. — Ctjlex hortensis Ficalbi. 

 1 "^ , Logie, Elgin, 11. ix. 1911 (F. Jenkinson). In the Cambridge 

 Museum. 



The occun-ence of this species in the North of Scotland is very 

 surprising, as until recently it was not known outside the Mediterranean
