A Synoptieal View of the Mosquitoes of British Guiana. 195 
GeNUS GNOPHODEOMYIA. Theobald. 
This genus is formed for a mosquito found in Berbice and bred from 
larve by Dr. Rowland and the writer. It is so far the only known 
representative of the genus. Messrs. Dyar and Knab have restored 
it to the genus Culex under the name C. azkenii. (B.G. Medical Annuals 
1905, pp. 25, 29, 32, 34. 1906, pp. 60, 69, 71, 72,76. 1908, pp. 9, 10, 
23.) V Scutellum with narrow curved scales all over, and six bristles 
on mid lobe 3-3 on each side of a bare space in middle. 
Gnophodeomyia inornata. Theobald. 
Messrs. Dyar and Knab have separated a species near above sent to them by Mr. H. B. Moore. 
Genus Leucomyia. Theobald. 
Our Culex confirmatus Arribalzaga (1891) has been removed to this 
genus and scapularis, Rondani (1848) identified with it. Possibly 
another species is local, that identified by Professor Howard as Aedes 
Oswaldi (v. B. G. Med. Annual, 1908, p. 13.) 
Leucomyia Scapularis. Rondani. 
Legs unbanded, thorax with silvery scales in front, brown scales 
behind. 
(B. G. Med. Ann., 2905, pp. 18, 27, 36. 1906, pp. 68,75. 1908, p. 10.) 
GeNUS CULICELSA. Felt. 
One species occurs in the colony. The genus was founded on our 
common C. taeniorhynchus Wiedemann. 
Culicelsa Taeniorhynchus. Wiedemann. 
Proboscis banded. Legs basally banded. Abdomen basally 
banded with lateral comma-shaped white markings on each 
segment. 
(B. G. Med. Ann., 1905, pp. 17, 26, 31. 1906, pp. 65, 67, 68, 69, 72, 73. 
1908, p. 20.) 
Genus Protocutex. Felt. 
This genus was founded by Velt on our C. serratus, separated from 
Culex mainly on characters of male genitalia. Theobald adds to the 
definition the palp characters of female palpi 5 segments, male with 2 
apical segments swollen. 
Protoculez serratus. ‘Theobald. 
Thorax with broad median band of creamy broad curved 
scales and lateral brown narrow curved scales. ; 
(B. G. Med. Ann., 7905, pp. 17, 27, 29, 36. 1906, pp, 68, 79, 7908, p. 23.) 
Genus CuLex. Linus. 
The seven local species retained in this genus by Mr. Theobald 
are difficult to synoptise and vary greatly, but I believe most of the 
forms will find a place in the following groups.
