100 Records of the Indian Museum. [Vol. IV 



In the genus Neocellia : indica, Theobald. 



intermedia , Rothwell. 

 dudgeonii, Theobald. 



In the genus Aldrichia : error , Theobald. 



Rossi, Giles, for which Mr. Theobald proposed a genus called 

 Pseudomyzomyia, and halli, James, which is a new species not yet 

 assigned to a genus, are not included in the list ; the}' will be 

 considered separately in this account. 



For the arrangement of the species in this second large group — 

 the group in which scales are present on the abdomen — I retain 

 the names of the groups Nyssorhynchus, Myzorhynchus, Cellia, and 

 Neocellia, but I alter ]\Ir. Theobald's definitions of these groups so 

 as to make them represent clearly the scale characters of the 

 groups. In the second place I change the position of one or two 

 species that have been placed in wrong groups, and in the third 

 place I create two new groups, one for rossi, the other for halli. 

 I am unable to say anything about the genus Aldrichia, as I 

 have not seen the species which represents it. 



Dealing first with the group Nyssorhynchus I agree with 

 Mr. Theobald in regarding the Indian species maculatus as a suitable 

 type of a group of anophelines characterized by the presence of 

 scales on only the last one, two, or three segments of the abdomen, 

 and I find that the scale structure of this species agrees in all 

 important respects with that of fuliginosus, jamesi, thcobaldi, 

 maculipalpis and kancari. My definition of the group characters is 

 as follows : 



Genus 5. NYSvSORHYNCHUS, Blanchard. Abdomen ivith the 

 first five or six segments ornaniented with hairs only. The last three 

 or two segjnents and the genital processes carry in addition a number 

 of rather long, blunt-ended true scales on both the dorsal and ventral 

 surfaces. On the 8th segment and the genital processes the scales mav 

 be arranged in patches or may cover the surface more or less evenly ; 

 but they are never aggregated together to form tufts of any kind. 

 Thorax with the dorsum covered ivith quite broad true scales usually 

 arranged in more or less parallel lines. On the anterior promontory 

 the scales are long and sharp-pointed and form a small bunch projec- 

 ting over the neck on each side of the middle line-, on the mid region 

 and posteriorly they are broader and some are blunt-ended. The 

 scutcllum carries a number of similar scales. Prothoracic lobes with- 

 out a tuft of scales. Head with the usual kind of upright forked 

 scales. 



Type of the genus, maculatus, Theobald. The generic charac- 

 ters are shown in Plate x, figs, i to 6. 



I place the following species in this group : — 



maculatus, Theobald. 

 fuliginosus , Giles. 

 jamesi, Theobald. 

 theobaldi, Giles
