Mr. Theobalds new Classification of " Anopheles " 



on the heads of members of this genus, instead of the three kinds 

 usually found on the heads of most other "culex" mosquitoes ; and 

 the genera Panoplites ( = Mansonia), Tceniorhynchus and others by 

 reason of their peculiarly shaped wing scales. Mr. Theobald has 

 recently adopted a new classification of " anopheles" mosquitoes 

 based almost entirely on scale structure, in which he divides these 

 mosquitoes under 11 new genera as follows : 



Genus 1. Anopheles. Meigen. 



2. Myzomyia. Blanchard. 



3. Cydoleppteron. Theobald. 



4. Stethomyia. Theobald. 



5. Pyretophorus. Blanchard. 



6. Arribahagia, Nov. gen. 



7. Myzorhynchus. Blanchard. 



,, 8. Nyssorhynckus. Blanchard. 

 9. Cellia. Theobald. 



. ,, 10. Aldrichia Theobald. 



,, 11 Christia. Theobald. 



The characters upon which these new genera are founded may 

 be tabulated thus : 



SUB-FAMILY ANOPHELINA. 



Thorax and abdo- 

 men with hair- 

 like curved scales. 



Thorax with narrow 

 curved .scales; 

 abdomen hairy. 



Prothoracic lobes 

 simple ; no flat 

 head scales. 



Prothoracic lobes 

 mammilated : me- 

 dian flat scales. 



Wing scales lanceolate... Anopheles. 



Wing scales mostly long 



and narrow ... Myzomyia. 



Wing scales partly large 



and inflated ... Cydoleppteron. 



Wing scales lanceolate Stethomyia. 



Wing scales small, lan- 

 ceolate or narrowed . . . Pyretophorus. 



Thorax with hair-like curved scales ; some narrow curved ones in 

 front ; abdomen with apical lateral scale tufts and scaly venter, 

 no ventral tuft 



Arribalzagia. 



Thorax with hair-like curved scales ; abdominal scales on venter 



only, with a distinct ventral apical tuft; no lateral tufts ... Myzorhynchus.
