EMPEDA, Os. 8ac. 



My Erioptera brevior {Fauna, p. 452 ^ $, 1912) is an Empeda, and my 

 Empeda inconspicua [loc. cit., p. 475(^9) i** identical. Both are from the 

 Darjiling District and the types of both are in the Indian Museum. 

 An additional specimen from Pashok, Darjiling District, 3,500 ft., vi-16 

 (L. C. Hartless). 



Gonomijia antica, Brun. {Fauna, p. 568, 1912) is an Empeda, as pointed 

 out by Bergroth. The relative positions of the tip of the auxiliary vein 

 and origin of the 3rd vein vary in Gonomyia, Empeda and Leiponeura. 



GONOMYIA, Mg. 



In my Fauna volume (1912) the following new species are described : 

 iHcompleta, p. 471 (^ $, Bengal (var. Iocs.) ; E. Himalayas ; flaromar- 

 ginata, 472 ^ $, Darjiling District ; affinis, 472 (^ $, Darjiling District ; 

 aperta, 473 ^, Bengal ; proxima, 474 ^ $, Bengal and Nepalese Hima- 

 layas. Types of all the species in Indian Museum. 



In the Appendix to the above volume (p. 568) is described G. antica 

 from the Darjiling District, which is an Empeda. The demarcation of 

 the dorsum from the sides of the thorax in flavomarginata seems to fade 

 considerably after death. A better distinction between these two 

 species than that given in the " Fauna " is as follows, but the relative 

 position of the posterior cross vein must not be relied upon too closelv. 



Basal section of 3rd vein very short, even punctiform, at 

 most one-fourth the length of the anterior cross vein. 

 1st posterior cell conspicuously narrowed at tip . incompleta. 



Basal section of 3rd vein of considerable length, from one- 

 half to nearly as long as anterior cross vein. 1st 

 posterior cell only slightly narrowed at tip . . flavomanjinatn. 



I am glad to see that Alexander does not remove from Gonomyia 

 those species with only one submarginal cell. Some regard these as a 

 separate genus {Leiponeura, Skuse) and would refer them to the 

 Rhamphidini, and Bergroth would thus refer my G. incompleta and 

 fiacomarginata, but Gonomyia in the wide sense forms a natural group. 



Alexander describes hryanti, sp. nov. {Proc. U. S. Nat. Mus. XLIX, 

 p. 173 (;J, 1916) from Java. Type in the U. S. Museum. 



Edwards records G. nebidosa, de Meij. from Arisan, Formosa, 8,000 

 ft., lO-x-12, two 9 $ {Nitobe), including it in the subgenus Lijiophleps.^ 



The MONGOMA group. 



It seems advisable to erect two new genera in this group for forms 

 in which the 2nd longitudinal vein is unforked. The venation appears 

 cjuite constant in the three genera into which Mongoma has already 

 been split up. 



Alexander calls my attention to an error in my first Tipulidae paper 

 {Rec. Ind. Mus. VI). On p. 291 it is stated that australasiae, Skuse is a 

 strict Mongoma, and on p. 296 that it is congeneric with Paramongoma. 

 The latter is an error ; it belongs to Mongoma, sensu strictu. He also 

 says there are intermediate species which throw all the genera formed 



See note under Atarba, p. 308, respecting three species that Alexander would refer 

 to Leiponeura.
