50 THE SCOTTISH NATURALIST 



list is based upon old records. The following can be 

 confirmed : 



Limnobia tripunctata, F., both sexes, Musselburgh, June and 

 July 1906-7; Argyra diaphcifia, F., both sexes, Callander, 19th 

 June 19 1 9, and Balquhidder, 26th June 19 19. 



The following sixty-three species are all additions to 

 the Forth list. I have a great many Mycetophilidas, but 

 these I hope to deal with at another time : 



1. Simulkim variegafi/?n, Mg. 2 ^, Arniston, 17th July 

 1906 (Rev. J. Waterston). 



2. Schizohelia leucopeza^ Mg. $ , Botanic Gardens, Edinburgh, 

 15th July 1904 (J. W.). 



3. Forcipomyia ciliata, Winn. Bred in some numbers from 

 fungus in dead stump, banks of Esk, Musselburgh, in March 

 and April 1905. The larva is of the usual terrestrial form with 

 spathulate appendages. 



4. Fa/pojnyia flavipes, Mg. ^ $, Musselburgh, June 1904, 

 also Aberlady, June 1905. The three last species belong to the 

 genus Ceratopogon of Verrall's list. All determined by Mr 

 Edwards. 



5. Limnobia qiiadri?iotata, Mg. $, Polton, 6th August 1906; 

 S, Arniston, 17th July 1906 (J. W.); $, Callander, 30th 



July 1917. 



6. L. flavipes^ F. 2 c^ , Blackford Hill, 7th June 1904 (J. W.); 

 common at Polton, 25th June 1915. 



7. L. sfigma, Mg. 2 c? , 3 ? , Polton, August and September 

 1906. The ? 9 have a black ring at apex of femora as in ^ ; 

 Schiner says they are entirely yellow in the $ , but Zetterstedt 

 makes no mention of a difference in the sexes. I can find no 

 Scottish records (confirmed by Mr Edwards). 



8. L. trivittata, Schum. (^ , Arniston, 17th July 1906 (J. W.). 



9. L. macrostigma, Schum. 3 $, 1$, Polton, 25th June 

 1915, all dark specimens. 



10. Dicranomyia modesta, Mg. ^, Musselburgh, 27th June 

 1907. 



11. D. lutea, Mg. 2 9) Callander, 3rd June 1916, seem to 

 be the same species as Verrall's. Unfortunately, I do not 

 know the c^ . Schiner says lutea is perhaps only a var. of modesta, 

 but the antennae are quite different.
