98 Records of the Indian Museum. [Vol. IV. 



Genus i. NEOSTETHOPHELES, nov. gen. Abdomen with 

 hairs hut without scales of any kind. Thorax with hairs and as a 

 rule without scales of any kind, but in one or two species a few 

 long, exceedingly narrow, false scales^ may be present on the anterior 

 promontory only. Prothoracic lobes with hairs but without scales. 

 Upright forked scales of the head very narrow in their whole length 

 [rod shaped). 



Type of the genus : aitkeni, James. The distinguishing char- 

 acters of the genus are shown in Plate ix, fig. i. 

 I place the following species in this genus : — 



aitkeni, James. 

 immaculatus, Theobald, 

 culiciformis , James and Liston. 



Genus 2. MYZOMYIA.. Blanchard. Abdomen with hairs but 

 without scales of any kind. Thorax with the dorsum clothed with 

 long, very narroiv, sharp-pointed, curved scales more numerous ante- 

 riorly and forming on the anterior promontory a bunch projecting 

 over the neck. Nearly all the scales are false scales. Prothoracic 

 lobes with hairs but without a tuft of scales. Upright forked scales 

 of the head of the Visual anophelinc type, that is broadly expanding 

 from the base to the apex. 



Type of the genus: culici fades, Giles. The distinguishing 

 characters of the genus are shown in Plate ix, fig. 2. 



I place the following species in the genus : — 



culicifacies, Giles. 



listoni, lyiston (= cJiristophersi , Theobald). 



culicifacies, variety punjabensis. 



turkhudi, Liston. 



leptomeres, Theobald.^* 



Genus 3. PATAGIAMYIA, nov. gen. Abdomejt with hairs 

 but without scales of any kind. Thorax with the dorsum clothed 

 with long, narrow, curved, sharp-pointed scales which form on the 

 anterior promontory a thick bunch projecting over the neck. Some of 

 the scales are false scales and some are true scales. Prothoracic lobes 

 with a conspicuous tuft of rather broad true scales projecting anteri- 

 orly. Upright forked cephalic scales of the usual broadly expanding 

 type. 



Type of the genus: g?g«s, Giles. At present the only other 



1 In this revision false scales are defined as those without clearly marked striae. 

 There may be an app^aranre of linear marking, but separate striae cannot be 

 counted. True scales always have definite bars or striae passing from the base to 

 the apex of the scale. These striae often project beyond the apex, and when 

 the scale is examined under the microscope they can be easily counted. 



2 When a species is marked with an asterisk it means that I have not examined 

 its scale ornamentation in detail and that it is placed in the genus only provi- 

 sionally.
