cream, proboscis with a small white ring at the union of the 

 front third with the two basal or hind thirds, black eyes, the 

 extremity of the abdomen as if truncated. Its sting is painful. 

 The specimens of this kind in other localities are transmitters 

 of the filaria banorofti, as in Zambesi, Lake Nyassa (Africa),

 strips cyaneo-micantibus; pedibusnigris, coxis, femorumque ba- 

 si pallida ; femoTtum tiarum que extreme aipice supreme niveis".

I'm-nota-cnid- social is, Theobald. 



A mosquito captured by Mr. E. Gros, assistant Las Ani- 



mus Hospital. 



Uranotaenia lowii, Theobald. 



A very SHIM II mosquito caught on the fiy. Mr. J. R. Taylor 

 has succeeded in getting the larvae until now unknown. The 

 main in this species is that both sexes have the pal par very 

 short, and the tarsus of the hind legs white. 



Culex corniger, Theobald. 



The general color of this mosquito is light gray in both 

 sexes. We are not familiar with the biology of this insect. The 

 samples we have examined have been sent to us by the National 

 Department of Agriculture. We have not been able to catch it. 



Culcx similis, Theobald. 



This mosquito is very similar to the cubensis, erroneously 

 known formerly by nigritulus. It is smaller than the cubensis, 

 the abdominal bands not so clear.
