Genus 18. THEOBALDIA. Neveu-Lemaire. 
(Compt. Rendus. d. Seances d. la Soc. d. Biol., 29 Noy., 1902.) 
(Plate X.) 
Palpi long in the g, the two apical joints swollen, the palpi 
being clubbed as in g Anophelina, three-jointed, the other three 
pseudo-joints not being complete, two apical joints and apex of 
the long joint with hair tufts; 9? palpi distinctly five-jointed, 
the three basal joints small, the fourth long, and the apical one 
minute. Head scales moderately large. Wings with many large 
lanceolate scales, which become collected into patches forming 
more or less distinct spots. 
The respiratory siphon of the larva is rather short and thick. 
The eggs are laid in large rafts. 
These spotted winged mosquitoes form a natural group, 
easily distinguished in the ¢ by the clubbed antennae and in 
both sexes by the thick wing scales, many of a lanceolate form, 
and collected here and there into groups forming spots. 
The following species come in this genus :-—spathipalpis 
(Rondani) ; glaphyroptera (Schiner) ; incidens (Thomson) ; and 
the type species annulata (Meigen), with the allied Ficalbii 
(Noe). 
THEOBALDIA ANNULATA. Meigen. 
Culex annulatus. Meigen. 
(Mono. Culicid. I., p. 331, 1902.) 
This species has been made the type of a new genus by 
Neveu-Lemaire. I had made C. incidens the type of a new 
genus, Professor Aldrich pointing out to me the generic im- 
portance of the wing scales. My colleague, Neveu-Lemaire, has, 
however, founded a genus on the palpal nk es which include 
incidens and others. 
The ¢ genitalia of annulata has the clasper simple with an 
asymmetrically piaced terminal tooth (Fig. 80). 
Additional localities.—Interlaken, Switzerland (Rey. E. A. 
Eaton); France generally ; United States (Miss Ludlow). 
Late appearance in England.—There is no doubt that this 
large mosquito hibernates in sheds, cellars, ete., during the 
winter. They are mainly noticed indoors in Kent in October, 
and now and then in the first week of November, but during
