374 Prof. Westwood’s Descriptions of 
sexes of one and the same species (L. brasiliensis), 
although they differed in the structure of the antenne, 
and slightly also in the veining of the wings, the male 
haying an additional longitudinal vein running to the 
apex of the wings. 
The third specimen was an unique insect from Canada, 
which I obtained from the collection of the late A. H. 
Haworth, and which agreed with the male from Bahia in 
the antenne and wings (L. canadensis). 
Previous, however, to the publication of my memoir 
containing the description of Limnoliorhynchus in the 
French Annalles for 1835, Mr. A. H. Haliday had pub- 
lished the characters of a British genus with a long 
proboscis in the first volume of the ‘Entomological 
Magazine,’ January, 1833, under the name of Geranomyia 
unicolor, of which a figure and detailed description were 
published by Mr. Curtis in his ‘ British Entomology,’ 
pl. 578, on November. 1st, 1835.* This insect, having 
14-jointed antenne, is congeneric with the males of 
Tamnohiorhynchus brasiliensis and canadensis, leaving 
the generic name to be restricted to the female of 
L. brasiliensis.

* The following are the chief characters of Geranomyia given by 
Mr. Curtis:— Antenne alike in both sexes, 14-joimted. Trophi 
elongated and porrected, forming a proboscis considerably longer 
than the antenne. Labrum long and linear, slightly hairy at the 
apex. Tongue very long and linear, pointed, anda little dilated below 
the apex, which is hairy. Lip very long, divided from the base, 
forming two pilose branches, terminated by oblique elliptical lobes. 
Palpi clothed with short hairs, short, biarticulate ? [The veins of 
the wings are arranged as in L. brasiliensis, male.| !
