INSECUTOR INSCITI^ MENSTRUUS 75 



would restrict this name to the present species, with which all 

 the characters that can be ascertained agree. Edwards adds to 

 my synonymy the following references : 



Ctilex sergenti Theobald, Mon. CuHc, iii, 218, 1903. 

 Culex pyrenaicus Brolemann, Ann. Soc. Ent. France, Ixxxvii, 

 427, 1919. 



In regard to C. pipiens, the interesting observation is made 

 that the Calif ornian form comitatus D. & K. is identical with 

 the forms pallens Coq. from Japan, and that the species was 

 introduced to our west coast from Japan. The eastern pipiens, 

 being introduced from Europe, shows the normal type of 

 structure. 



Besides the synonymy indicated, Edwards has introduced a 

 number of new characters for generic definition, which will be 

 of great value.

By CHARLES P. ALEXANDER 



The high mountains of the Oriental Region support a rich 

 fauna of crane-flies of the tribe Limnobiini. The four unde- 

 scribed species of Limnohia (Limonia) were included in ma- 

 terial sent to me by Mr. J. B. Corporaal, collected in Sumatra, 

 and by Mr. Teiso Esaki, collected in Formosa or Taiwan. The 

 author's thanks are extended to the collectors of this material 

 for the privilege of retaining the types. 



Limnobia megastigma, new species. 



General coloration yellow ; antennal scape yellow, the flagel- 

 lum black ; raesonotal praescutum with four brown stripes ; 

 femora brown with an obscure yellow subterminal ring, the tips 

 black ; wings yellow, the stigma very large, brownish black ; 

 r at tip of i?i.
