Bancroftia has two prominent tufts of hair-like scales, or scale-like 

 hairs, on the scutellum ; Bathosoinyia has peculiar & genitalia, 

 and the " ist posterior cell almost uniform in breadth " (!) ; Car- 

 rollia has the abdominal segments in the ^ deeply constricted at 

 the base; Ceratocystia is synonymous with Gr abhamia {t. Coq.) ; 

 Culicada is said to have 4-3ointed cf palpi, but fuller information 

 on this is required ; Diceroniyia is synonymous with Mansonioides 

 [t. Edwards) ; Heptaphlehomyia is dealt with elsewhere (see p. 41); 

 Howardina was at first admitted by Edwards on claw characters, 

 but in a later paper he abandons it ; Lasioconops was founded on 

 a misconception, through some lepidopterous scales adhering, 

 accidentally to the type; Leucomyia is said to have 5-jointed o* 

 palpi; Mansonia is reputed to have 4.-iointed a* palpi ; Melanoco- 

 nion is a group of small black species with densely scaled wings ; 

 Microculex is a " small stout gnat totally different from any other 

 member of the genus ' ' (Culex) ; Mimeteculex has the two basal 

 antennal joints scaled ; Minieteomyia has the 2nd and 3rd anten- 

 nal joints rather enlarged ; Mochlostyrax based on larval characters, 

 is allied to Melanoconion in the adult stage ; Pardomyia is sup- 

 posed to possess a novel venation but differs only slightly from 

 normal Culex ; Pecomyia has unequal hind ungues in the c , said 

 to be unique, also the cf genitalia very marked ; Phagomyia is 

 included here on account of Theobald associating it with other 

 " genera " belonging here, though he says it is near Stegomyia \ 

 Pneumaculex was founded originally on larval characters only, but 

 the adult is now known and is said to be near Danielsia, judging 

 from the & genitalia ; Polyleptiomyia is included for the same 

 reason as Phagomyia ; Pseudoskusea has the mid-ungues of the cf 

 equal in size, a character found only in this genus ; Rachisonra 

 has the plumosity of the & antennae a little less dense than usual ; 

 Reedomyia has the cf genitalia " ver}'- marked"; Theohaldia 

 forms for Theobald a natural group of five species with spotted 

 wings, clubbed antennae and thick wing scales in cf and 9 , 

 Edwards ranking it generically distinct on claw characters ; 

 Thomasina is supposed to have the cf "palpi short and the 2 palpi 

 '' relativel}'' long " ' and Trichorhynchomyia [nom. nov. for Tri- 

 chorhynchns , preocc.) is said to be " very marked " and to be inter- 

 mediate between the Culex and Stegomyia groups. 



The Aedes group. 



Coming to a closer examination of the Aedes group we find 

 much difficulty in the ambiguous or actually negative information 

 afforded us as regards the palpal joints, and ^he plumosity or pilosity 



i The authors figure a d" head iu which the palpi are only a very little shorter 

 than the prosboscis, though their diagnosis reads " much shorter. ' ' Tnis exaggera- 

 tion of minute iifiEerences is the cause of the bulk of the trouble in understanding 

 culicid writer's meanings. They then figure an isolated '3;. palpus, so there is no 

 means of judging their idea of " relatively short." If they are drawn to the same 

 scale both are of equal length.
