 fuscopalpalis, Theo, Mon. Cul. V, p. 307 (1910). 



The type of C. mediopunctata is only a vai'iety of O. cumminsi with unusually 

 large abdominal spots, traces of which can almost always be seen. The male 

 genitalia of C. fuscopalpalis do not differ from those of O. cumminsi.

 2. 0. dentatus, Tlieo. (Culex), First Rep. Welle. Lab., p. 75 (1905). 



Evidently closely allied to O. cumminsi, but differs in the banded abdomen. 

 The male is at present unknown.

Several specimens from Algeria {Rev. E. A. Eaton) in the British Museum seem 

 to belong to this species. Some are very much paler than others, one having 

 the thorax and abdomen almost entirely buff-coloured, yet I feel sure it is only a 

 variety. This specimen agrees very well with Theobald's description of 

 G. maculosa, which makes it seem possible that the latter is only an extreme 

 form of O. nemorosus. The corresponding pale variety of Stegoimjia fasciata 

 (described by Mr. G. A. K. Marshall in the last number of this Bulletin) is 

 common in Algeria, as is an ochreous form of C. pipiens.

 „ ivillcocksii, Theo., Mon. Cul. IV, p. 294 (1907). 



The forms described as G. subtilis and G. loillcocksii only differ in having-the; 

 pale markings of the abdomen rather more extended than in typical C. dorsalis, 

 and are evidently merely pale varieties of Meigen's species. 



The ungual formula in all the specimens I have seen (including British 

 specimens determined by Mr. Theobald as G. dorsalis and as G. pulcrijjalpis, 

 and African specimens of G. subtilis ani G. ivillcocksii) is : cj" 2.1 — 1.1 — 1.1, 

 Q 1.1 — 1.1 — 1.1, and it is most probable that errors of observation' were made 

 in compiling the table 00 p. 285 of vol. IV of the Monograph of the Culicidae. 



I am not quite certain whether the species at present under consideration is 

 really C. dorsalis or C. pulcripalpis, Rond., or whether these two names are 

 gynonymous. Whichever may be the case, it is certainly the same as our British 

 species, which has always been known as C. dorsalis. It is curious, however, that
