Genus Anopheles. 
Unfortunately but few males of these mosquitoes have been 
sent, so that the important structure of the £ ungues has not 
been properly examined in any but annularis and pseudopiclus , 
which agree with one another. 
The chief differences of these two species, A. Sinensis and 
A. barbirostris, and the sub-species of the former, may be summed 
up as follows :— 
A. Sinensis. 
1. Proboscis longer than palpi. 
2. White patch on border of wing 
below. 
3. Wing (costal) spots large. 
4. Scales elongated. 
5. Cross-veins close together. 
6. Border scales yellow. 
7. Apical fringe all yellow. 
sub-sp. Indiensis. 
1. 1st sub-marginal cell with base 
near 2nd costal spot at the 
junction of the sub-costal and 
costal veins. 
2. Scales as in annularis. 
3. Cross-veins separate. 
4. Border scales yellow. 
5. A pale patch on border of wing 
below. 
sub-sp. nigerrimus. 
1. Base of the first sub-marginal cell 
just in front of the costal spot. 
2. Apical fringe black. 
sub-sp. annularis. 
1. Palpi and proboscis nearly equal. 
2. No white patch on border. 
3. Costal spots small. 
4. Scales as in type. 
5. Cross-veins separate. 
6. Border scales yellow. 
7. Apical fringe yellow. 
sub-sp. pseudopictus. 
1. 1st sub-margiual cell with base 
near 2nd costal spot at the 
junction of the sub-costal and 
costal veins. 
2. Cross-veins close. 
3. Scales as above. 
4. No pale patch on border of wing 
below. 
A. barbirostris. 
1. Bases of the two fork-cells nearly 
level. 
2. Base of 1st sub-marginal cell not 
near junction of sub-costal and 
costal. 
3. Scales broader. 
4. No white spot on lower fringe. 
5. Black apical patch to fringe. 
G. Palpi unbanded. 
7. Border scales black. 
13. Anopheles superpictus. Grassi.

Lincei Stud. d. uno Zool. sulla Malaria, p. 78 (1900), Grassi.) 
(Fig. 11, PI. III.) 
Thorax brown, with white scales. Abdomen brownish- 
yellow, with distal darker borders. Legs dark brown, with 
apical white tarsal bands. Wings with four black spots on the 
yellow costa.
