NOTES ON THE DIFFERENT GENERA 567 



Genus. Myzomyia, Blanchard ; Grassia, Theobald. 



Comp. rend. heb. Soc. Biol., No. 23, p. 795, Blanchard ; "Mono. Culicid.," 

 1910, iii, p. 24 ; v, p. 16, Theobald. 



This genus occurs in Asia, Africa and South America, Europe and East Indies. 

 The type is M.funesta, Giles, found in Central and West Africa. Although structur- 

 ally there is not much difference between this genus and Anopheles, they differ 

 greatly in appearance, and there are usually a few narrow curved thoracic scales 

 projecting over the head, whilst the wing scales are much smaller in proportion, and 

 the wings more uniformly spotted, always so along the costa. Ftmesta and hitzii 

 are undoubtedly malaria bearers and also rossii. 



Genus. Neomyzomyia, Theobald. 



"Mono. Culicid. ,"1910, v, p. 29. 



A single species only occurs in this genus, N. elegans^ James, from India. In 

 this genus, which is near to Myzomyia, the fourth long vein is very near the base 

 of the third, and there are outstanding scales on the prothoracic lobes, and there is 

 a marked tuft of dense scales at the posterior angles of the head. 



Genus. Cycloleppteron, Theobald. 



" Mono. Culicid.," 1903, ii, p. 312 ; 1903, iii, p. 58 ; 1910, v, p. 33. 



Two common species only occur in this genus, C. grabhamii, Theob., from 

 Jamaica, and C. mediopunctatus, Theob. (Lutz., ms.), from South America. The 

 chief character is the presence of large black inflated pyriform scales on the wings. 

 The palpi are densely scaled. Neither have been shown to be malaria bearers. 



Genus. Feltinella, Theobald. 



" Mono. Culicid.," 1907, iv, p. 56. 



A single species, so far only found in this genus. The basal lobes of the male 

 genitalia of two segments, the prothoracic lobes with dense outstanding scales. 

 The species, F. pallidopalpi, Theob., occurs in Sierra Leone. 



Genus. Stethomyia, Theobald. 

 " Mono. Culicid.," 1903, iii, p. 13 ; 1907, iv, p. 59 ; 1910, v, p. 35. 



Four species occur in this marked genus one S. nimba, Theob., from British 

 Guiana and Para, another S. fiagalis, Theob., from the Malay States, S. culici- 

 formis, James and Listen, from India, and S.pallida, Ludlovv, from India. 



The former may be a malaria carrier, for Dr. Low says : " Malarial fever is got 

 amongst the Indians and often of a severe type. In that connection it is interesting 

 that in the interior, at a place called Corato, I got an entirely new Anopheles in 

 large numbers." The genus is easily told by its unornamented wings, flat head 

 scales, mammillated prothoracic lobes and long thin legs. 



Genus. Pyretophorus, Blanchard; Howardia, Theobald. 



Compt. rend. heb. Soc. BioL, No. 23, p. 705, Blanchard ; Joiirn. Trop. Mect.,v, p. 181 ; 



and " Mono. Culicid.," 1903, iii, p. 13 5 1910, v > P- 3$, Theobald. 

 Forty-four species come in this genus, of which Anopheles costalis, Loew, is the 

 type.
