larger appearance owing to the considerable enlargement of the 

 wings, which in impunctata are smaller than usual. 



BRUNETTIA, Annand., and PARABRUNETTIA, gen.nov. 



The characters of Brunettia (as defined by its author) which 

 appear to me to be most strikingly generic are the closely scaled 

 wings and the presence of prominent S-shaped chaetae on the 

 flagellar joints. 



To these may be added the lesser ones of broader wings than 

 in the other genera in this family, but this character is almost 

 certain to be a somewhat variable one. 



The original species was superstes, Annandale, which was at 

 first placed b}^ its author in Diplonema, Lw. (an extinct genus), and 

 afterwards removed to the present genus, which was established 

 by Dr. Annandale for its reception ; and to this new genus he 

 added a second species from South India, travancorica. 



As superstes was placed first (of the two species) in the new 

 genus, it must be regarded as the generic type, as indeed, was 

 intended and expressed by its author. Moreover, as superstes has 

 a venation identical with that of Pericoma,^ that t3^pe of venation 

 must stand good in all species of Brunettia. 



B. travancorica, Annand. (which was afterwards recognised as 

 s^monymous with my Psychoda atrisquamis) , has, however, 

 Psychoda-Vik.& venation, and therefore this species cannot remain 

 in Brunettia, for it would be illogical to allow the two types of 

 wing in a single genus, when Psychoda and Pericoma themselves 

 are mainly differentiated by this difference in the venation. 



It therefore appears that the genus Dr. Annandale has flatter- 

 ingly named after me, still contains but the original species 

 mperstes, the consequence being that a new genus must be formed 

 for all those other species of the present group that possess 

 Psychoda-like venation. 



This new genus it is proposed to call Parabruncttia, and it 

 dift'ers from Brunettia primarily in the different venation. 



Its other characters may be regarded as — 

 (2) the presence of closely placed dark imbricating scales on at 

 least some considerable portion of the wings, on both their upper 

 and lower surfaces, or on the under side alone * ; (3) the surface 

 of the wing generally rather thickly covered to some considerable 

 extent with more or less longitudinally placed hairs ^ ; (4) chaetae 

 present on the flagellar joints (possibly not on all of them, 

 irrespective of the apical joint, which, even in B. superstes^ is 

 devoid of them). They are not so large nor so conspicuous in any 



1 That is to say, the 3rd longitudinal vein ends a Uttle below the wing tip, 

 instead of at the tip. 



2 Any species (if discovered), with scales on the upper side of the wing only, 

 would logically fall in the new genus. 



8 These are absent in two species provisionally placed here, but this may be 

 better regarded perhaps as a subgeneric character, as species both with and 

 without hairs on the surface of the wings occur equally in Psychoda and Pericoma.
