4342 Insects, fyc. 



the thirteen species of which, acknowledged as European, have all 

 been found in Ireland, and eleven within the limits of the County 

 Dublin. 



That other collectors, however, of whose existence I may be as yet 

 unaware, have taken more, and possibly remarkable species not known 

 to me as occurring in the neighbourhood, I would not wish to seem 

 to doubt, and I hope they will not fail to make their discoveries pub- 

 lic, either by sending notices of them to the ' Zoologist,' or, if they 

 prefer it, communicating them to me for a future Appendix : thus 

 may the very imperfections of the present list tend to the advancement 

 of science, and to the encouragement of new votaries to the study, 

 who, if they would reap the highest and best fruit of their labours, 

 will not forget, I trust, — 



" To trace in Nature's most minute design 

 The signature and stamp of Power Divine, 

 Contrivance intricate, expressed with ease, 

 Where unassisted sight no beauty sees, 

 The shapely limb and lubricated joint, 

 Withiu the small dimensions of a point; 

 Muscle and nerve miraculously spun, 

 His mighty work, who speaks and it is done ; 

 The Invisible in things scarce seen revealed, 

 To whom an atom is an ample field." 



Cowper. 



So will the lover of Entomology, whom the cheering fragrance of 

 returning spring once more tempts to ramble forth from the scenes of 

 his winter labours, soon finds his w r ay — 



" To regions where, in spite of sin and woe, 

 Traces of Eden are still seen below, 

 Where mountain, river, forest, field, and grove, 

 Remind him of his Maker's power and love."

Note on Ophiocoma Ballii. — Since my former notice of this species, I have seen 

 a very perfect specimen in the possession of Mr. Edwards, of Banff, having six dis- 

 tinct and fully developed rays. — George Harris ; Gamrie, April, 1854.
