Anopheles maculatus. 



and apical bands, the fourth has also broad basal and apical bands, 

 and the fifth is pure white throughout its length. 



Wings with the veins clothed mostly with pale narrow scales 

 and with some black ones, forming spots arranged almost exactly 

 as in the wings of theobaldi. 



Characters of the larva. The frontal hairs are simple and un- 

 branched. Palmate hairs are borne by the second to the seventh abdo- 

 minal segments ; the terminal filament of each leaflet is very short. 



Habitat and observations. This species occurs in Lahore in 

 March and April ; in the Bengal Duars (August and September), 

 and at Kurseong at an elevation of 5^000 feet. It also occurs in 

 Hong- Kong (China) and in the Straits Settlements. 



This "anopheles " very closely resembles theobaldi and is pro- 

 bably only a geographical variety. The difference in the frontal hairs 

 of the larva is noteworthy, but such minor differences have been 

 noted in larvae of undoubtedly the same species. As in theobaldi 

 we have been unable to detect any scales on the abdomen (excluding 

 the abdominal processes) of this species, and for this reason we 

 should be inclined to remove it, with theobaldi, from the genus 

 Nyssorliynchus, in spite of the fact that Mr. Theobald regards it 

 as the type-species of that genus At any rate, if scale structure 

 is of any generic value, it seems wrong to place this species in the 

 same genus as stephensi and willmori, the abdomens of which are 

 almost entirely covered with large scales. 



The different mosquitos in this group are very liable to be 

 mistaken for one another. They can readily be divided into two 

 groups according as the tibiae and femora are (a) unspotted, (b) 

 spotted. 



Under (a) would come karwari and fuliginosus. As a rule, 

 karwari has four bands on the palpi while fuliginosus has only 

 three, but in this latter mosquito there are occasionally four bands 

 on the palpi. Again, karwari has, as a rule, only one segment 

 entirely white in the hind tarsus, while fuliginosus has three, but 

 occasionally only two. These mosquitos, however, are most easily 

 distinguished from one another by the fact that the wing of karwari 

 is very much lighter than that of fuliginosus. 



Under (b) come jamesi, macuiipalpis, theobaldi, and maculatus. 

 The two former can be separated by the fact that they have 



100"!
