CLASSIFICATION OF THE MOSQUITOES 233 



Yellow-fover Commission, and is of some importance to 

 us, as Cuba is so near our Southern States, and American 

 citizens have so many interests in Cuba. Another species 

 of Megarhinus, namely, grandiosa, Williston, has been 

 added by Mr. Coquillett. 



It is unfortunate that this table has to be published be- 

 fore the monographic work by Mr. F. Y. Theobald, the 

 English expert, who has had exceptional advantages in 

 his studies, for tjie British Museum, of the mosquitoes of 

 the whole world, makes its appearance. From correspond- 

 ence with Mr. Theobald I learn that his opinions differ in 

 some respects from those of Mr. Coquillett in regard to the 

 proper names for some of our mosquitoes. For example, 

 the brownish, sordid mosquito which we called CuJex 

 pungeus is, in Mr. Theobald's opinion, composed of two 

 distinct species, namely, Culex jnpiens (a common Euro- 

 pean mosquito), and Culex fatnjam, an East Indian 

 species which he says is identical with Culex pungens, and 

 which he states occurs abundantly in many parts of the 

 world, extending north and south of the Equator to about 

 38^ north and south latitude (just about the range of the 

 yellow-fever mosquito). Mr. Theobald is also inclined to 

 think that the Culex impiger of AValker is identical with 

 the species known to entomologists as Culex ni gripes of 

 Zetterstedt, and he also has a mosquito from North Amer- 

 ica which he thinks is Culex aimidatus Meigen, a form 

 which we have not recognized in the United States. Mr. 

 Theobald has also received from Canada an Anopheles 

 which he thinks is a variety of A. lifKreafus. This also 

 is a species which is unknown to us in the United States.
