MALARIAL TRANSMITTERS 



373 



1. Palpi as long as proboscis in females; proboscis 

 straight. Anophelina. 



2. Palpi as long or shorter than proboscis in females; 

 proboscis curved. Megarrhinina. 



3. Palpi shorter than proboscis in females. Culicina. 

 Palpi shorter than proboscis in male and female. 



i . Scales on head only; hairs 

 on thorax and abdomen. 



Palpi as long or longer 

 than proboscis in male. 



The important ones from a medical standpoint are the Anophelinae 

 and Culicinae. 



Anophelinae 



Scales on wings, large and lanceolate. A nopheles. 

 Palpi only slightly scaled. 



Wing scales small and narrow and lanceolate. 

 Myzomyia. Only a few scales on palpi. 

 Large inflated wing scales. CydoUppteron. 

 2. Scales on head and thorax f 

 (narrow curve scales). 

 Abdomen with hairs. 



.? 



1. Abdominal scales only on ventral surface. 

 Thoracic scales like hairs. Myzorhynchus. 

 Palpi rather heavily scaled. 



2. Abdominal scales narrow, curved or spindle- 

 shaped. Abdominal scales as tufts and dorsal 



patches. Nyssorhynchus. 



3. Abdomen almost completely covered with scales 

 and also having lateral tufts. Cellia. 



4. Abdomen completely scaled. Aldrichia. 



i. Wing scales small and lanceolate. Pyretophorus. 



Scales on head and thorax 

 and abdomen. Palpi 

 covered with thick scales. 



NOTE. Of the above genera only CydoUppteron and Aldrichia are unproven 

 malarial transmitters. 



The following species of anophelines selected from the different 

 genera are important transmitters of malaria. 



Anopheles maculipennis. Wings with four spots located at bases of both forked 

 cells and of second and third longitudinal veins. No costal spots. Palpi yellowish 

 brown and unbanded. Legs unbanded. 



Myzomyiafunesta. Wings with four yellow spots on a black costa and two black 

 line spots on third longitudinal vein. Palps with three white rings. Proboscis un- 

 banded. Legs with faint apical bands. 



Pyretophorus costalis. Costa black with five or six small yellow spots. Palps 

 with two narrow white bands and white tip. Femora and tibias with yellow spots. 

 Apical tarsal bands. 



Myzorhynchus pseudopictus. Black costa with two pale yellow spots. Wing 

 fringe unspotted. Black palps with four pale bands. Apex of palps white. 



Nyssorhynchus fuliginosus. Black costa with three large yellow spots. 

 Numerous black dots on the longitudinal veins. Palpi black with white tip and two 

 narrow white bands. Last three hind tarsal segments white. 



Cellia argyrotarsis. Black costa with two distinct and several smaller white spots.
