KEFERENCES TO PLATE VII. 



1. Staurastrum avicula, a rather taller form than Ralfs'. — 2, This 

 may possibly be either a Staurastrum or Xanthidium. The blunt spines 

 are i^eculiar. — Staurastrum sp. ? — 4. Staurastrum anatinum ; if not 

 anatinum it is a very near form. Two positions shewn. — 5. Euastrum 

 binale ; generally distributed on heaths. — 6. Staurastrum aristiferum. 

 7. Xanthidium octocorne. — 8. Staurastrum Sebaldi : previously dis- 

 covered as a British plant by Mr. Wills in 1880, at Capel Curig. 



9. Staurastrum aculeatum : generally distributed, but not common. — 



10. Staurastrum megacanthum 1 so like, that I deem it the true species. 

 See remarks on No. 8. — 11. Staurastrum pilosum : not common. — 12. 

 Xanthidium fascicalatum. — 13. Staurastrum furcigerum : this and the 

 one preceding it are very common. — 14. Staurastrum inflexum : see 

 No. 8. — 15. Staurastrum margaritaceum : a widely-distributed species. — 

 16. Xanthidium sp. 1 pronounced to be so by Dr. M, C. Cooke ; species 

 doubtful, possibly a deviation from X. octocorne. 17. Xanthidium sp. ? 

 Copy of one drawn by me from a Welsh specimen of Mr. Wills, to 

 compare with No 16. — 18. Cosmarium amoenum : Ralfs gives habitats 

 Ambleside and Dolgelly, not common. — 19. Staurastrum sp. ? — 20. Stau- 

 rastrum arachne : Ralfs says "Dolgelly, very rare; Aberdeen." — 21. 

 Staurastrum pseudo-furcigerum 1 This form approaches the species 

 mentioned, but yet may be only a variety of S. furcigerum. No. 13 ; see 

 remarks on No. 8. — 22. Micrasterias papillifera : generally distributed, 

 but not common. — 23. Micrasterias Crux-Melitensis : a rare species. — 

 Nos. 1 to 21 are x 260, Nos. 22, 23 X 275 diams. 



WHARFEDALE ENTOMOLOGICAL NOTES. 



By J. W. Carter. 



j The following observations were made by my friends Messrs. J. 

 Firth, of Bradford, E. P. P. Butterfield, of Wilsden, and myself, 



' during a walk from Silsden to Grassington, on the banks of the 

 Wharfe, from Addingliam, on the 23rd of June last. In the evening 

 in Grass Wood, we tried the attractive mixture known as " sugar," 



' but not a single specimen visited it. It was our intention to remain 

 in the neighbourhood of Grassington the whole of the following day, 

 but owing to an unfortunate circumstance — one of our party being 

 taken seriously ill — we were compelled to leave very early in the 

 morning. , 



As the insect fauna of Wharfedale is very imperfectly known, we 

 L think it advisable to give a complete list of our captures.
