Character Differences Between AEDES STIMULANS (Female) and 

 AEDES CANTATOR (Female) 



Aedes stimulans 



1. Proboscis : vestiture brownish- 

 black intermixed with sordid white 

 scales, especially beneath. 



2. Palpi: clothed with black scales, 

 bases of joints with yellowish 

 white scales. 



3. Tori: brown and with a patch 

 of small white scales on inner 

 side. 



4. Prothoracic lobes: clothed with 

 dull whitish scales and black 

 bristles. 



5. Mesonotum : dark brown, disk 

 clothed with rich bronzy brown 

 scales, the anterior and lateral 

 margins and the ante-scutellar 

 space with sordid silvery scales. 



6. Scutellmn : clothed with pale sor- 

 did yellow-silvery scales, each lobe 

 with a group of black bristles. 



7. Coxae : pale brown. 



8. Wing Scales: black with dull 

 white ones intermixed, white 

 scales predominant only on sub- 

 costal vein, black ones elsewhere. 



9. Tibiae : black and white spots in- 

 rermixed. 



10. Claws: one tooth on each claw of 

 hind tarsi. 



Aedes cantator 



1. Proboscis: vestiture brownish- 

 black. 



2. Palpi: black scaled, tip minutely 

 white. 



3. Tori: pale yellow without, black- 

 ish within. 



4. Prothoracic lobes: clothed with 

 brown scales and black bristles. 



5. Mesonotum: dark brown, with 

 bright bronzy brown scales, yel- 

 lowish about ante-scutellar space 

 and a short stripe of light scales 

 on either side of it. 



6. Scutellum : clothed with yellow- 

 ish scales, each lobe with a group 

 of golden brown bristles. 



7. Coxae : orcherous yellow. 



8. Wing Scales : brownish black, 

 those on costa and first vein with 

 a blue reflection. 



9. Tibiae : small pale spot at base. 



10. Clazvs: claws of hind tarsi with- 

 out teeth. 



Probably the easiest way of determining to which of these species 

 a specimen belongs is to examine first the claws of the hind tarsi. If 

 there are no teeth on these claws the specimen is cantator; if teeth 

 are present, it is stimulans.
