I have next to consider the si)ecies rossi, which in its scale 

 ornamentation exhibits some of the characters of the group Myzo- 

 myia and some of the group Nyssorhynchus. An examination of 

 a large number of specimens of this mosquito has shown that 

 although minor differences in the degree and character of the scale 

 ornamentation are common, the chief features, as figured in plate x, 

 figs. 7 to II, can always be made out on unrubbed specimens. I 

 describe them thus : — 



Genus 6. NYSSOMYZOMYIA, Hoy. g^w. Abdomen with the 

 first seven or six segments ornamented with hairs only. The eighth 

 segment (someti)nes also the seventh) a)id the genital processes carry in 

 addition a number of scales similar in character and arrangement to 

 those of the group Nyssorhynchus. Thorax with the dorsum clothed 

 ivith hairs and narrow, curved, sharp-pointed scales of various 

 lengths and quite similar to those of the group Myzomyia. In addi- 

 tion there arc on each side of the anterior third of the dorsum a few 

 broader blunt-ended Nyssorhynchus-like scales. Prothoracic lobes 

 laithout a tuft of scales. Head ivith the usual type of upright forked 

 scales. 



The species is, therefore, representative of a group intermediate 

 between Myzotnyia and Nyssorhynchus, and is nearer to the latter 

 than to the former group. The term Nyssomyzomyia suitably 

 indicates that it possesses the characters of both groups and I 

 therefore apply this name to the genus instead of the name Pseudo- 

 myzomyia which Mr. Theobald proposed, but the characters of 

 which he has not yet described. The characters of the genus 

 Nyssoniyzomyia are shown in Plate x, figs. 7 to 11. 



I take up next the group NEOCELLIA, Theobald, several 

 members of which have usually been wrongly placed in the genus 

 Nyssorhynchus. The characters of this group are very different 

 from those of the group Cellia and the name Neocellia is therefore 

 quite misleading. Neonyssorhyjichus would have been a more 

 suitable name^ but the resemblance even to that group is not close. 



The t5'pe species of the group is the Indian species indica, 

 Theobald. I define the group characters thus : 



Genus 7. NEOCELLIA, Theobald. Abdomen with the dorsuni 

 of each segment clothed irregularly with hairs and long, rather broad, 

 blunt-ended scales. The scales are not aggregated together to form 

 tufts of any kind, but they are more numerous and thickly set on the 

 last tivo segments than on the others. On the ventral surface the first 

 five segments are devoid of scales, but on this surface of the 6th, yth, 

 and Sth segtnents they are present in considerable numbers, being 

 disposed irregularly but attached chiefly on each side of the mid line 

 and not forming tufts of any kind. Thorax clothed with broad true
