I AM induced to illustrate this genus and give a figure of the 

 male of this rare insect, in consequence of Meigen having seen 

 the female only, which sex is represented in his plate ; and 

 Macquart's figures are so bad that they are utterly useless. 



In some respects Lucina resembles Cordylura (pi. 4-85), the 

 abdomen of the male being incurved and horny ; nevertheless I 

 have little doubt that it is more nearly allied to theTetanocerae 

 and to Actora (Helcomyza, pi. 66), close to which Meigen has 

 placed it. 



Lucina Jasciata is the only species known of the genus, and 

 had only been found at Marseille until it was discovered by 

 my friend Mr. Haliday on the sands at Portmarnock near 

 Dublin, where he took both sexes in June and transmitted me 

 a very fine series. 



It may be observed that the seta of the antennae is not naked 

 as stated by Meigen and Macquart, and the abdomen appears 

 to be 7-jointed in consequence of a transverse suture near the 

 base. The shortness of the basal joint in the hinder tibias, the 

 inclination of the third and fourth longitudinal nervures at the 

 apex of the wing, the remarkable horny ball terminating the 

 male abdomen and the truncated tube of the female, are cha- 

 racters that distinguish Lucina from neighbouring groups. 



The Plant is Stellar ia nemorum (Broad-leaved Stitch wort), 

 communicated by J. Walton, Esq., from Knaresborough.
