(= Trichoprosoponiiiae, Dendromyiiiae, Limatinae oi Theobald), 

 " this group being entirely conventional." ' 



One oi the most valuable points in the paper is the recogni- 

 tion of most of the so-called " genera "" as sub-genera only. 



I have endeavoured to retain the sequence of genera as 

 near as possible to that followed in my Catalogue, for there is as 

 yet, apparently no uniform agreement as to the disposition of 

 many of the genera, even into the so called sub-families. 



Several genera admittedly hold intermediate positions, which 

 clearly supports the contention that the less the number of genera 

 in Culicidae, the more zoologically correct the classification. Res- 

 pecting the value of the so-called species the present writer offers 

 no opinion, but as authors are already speaking of "' Culex so-and- 

 so, and its allies," it is reasonable to conclude that considerable 

 doubt exists still as to specific limits, and that the opinion ex- 

 pressed four years ago in the introduction to my Catalogue 

 that " a few more years careful study of the family is more likeh 

 to result in the reduction than otherwise of the total number of 

 what today are regarded as distinct species '' seems within possi 

 bility of realization. 



Four new " generic " names are proposed in the present paper 

 for names alreadv preoccupied, and it is significant as showing how 

 little culicidologists concern themselves with dipterological litera- 

 ture, that three out of these five names should have been pre- 

 viously used in the order Diptera itself ! * 



Othei- names are so similar to long previously established 

 ones that confusion is at least probable. Such are Popca, Ludlow, 

 closely resembling Po/)/)^^ Stal. (1667), i-^ Hemiptera; whilst two 

 other recentlv established genera (non-Oriental) bear names re- 

 maikably sim'lar to others long established in other divisions ot 

 the animal kingdom. These are Carrollia, Lutz, practically pre- 

 occupied by Carollia, Gray (183S), in Mammalia, and by Carolia, 

 Cantr (1837), i'"* Mollu^ca ; a\so A nkvlorhynchus, Lutz, preoccu- 

 pied hy Ancylorhynchtis, Schonh. (1836), in Coleoptera. 



Miss Ludlow has emended her generic name Calvertia to 

 Calveriina (Can. Ent. , xli, 234), it being preoccupied by Warren 

 in Lepidoptera. 



There also exist two other very similarly named genera Calver- 

 tius. Sharp, in Coleoptera and Calveria, Carp., in Ech nodermata. 



During two tours made by me, one round the Punjab and 

 north-western part of India in T905 and one round the far east 

 in 1906, I collecte 1 a certain number of Culicidae but paid no 

 espe ial attention to their capture or preservation, with the result 

 that the cjndition of the specimens renders them practically 



J Col. Alcock now accepts for these groups the more appropriate names 

 " Me;.'alorhiniiia." " Anophehna," " Culicina " and •• Metanototrkhina " (Bull 

 Ent Res., ii, p. 24 r. 191 1). 



^ A hf h instance was included m the original MS of this paper - Aldvichta, 

 Tbeob. (preoccupied in Boniby?id .e by Coquillett) — but in his last volume Theobald 

 alters it to Aldrirhtnella This genus (Aldrithia) made another instance of 

 ig)iored preoccupation in Diptera !
