March, 1907.] KnAB : COPULATION OF StEGOMYIA CaLOPUS. 13 



Genus ANOPHELES Meigen. 

 Anopheles quadrimaculatus Say. 



Through the kindness of Dr. A. Handlirsch of the Vienna Museum, 

 Dr. C. von Kertesz of the Hungarian National Museum, Prof. R. 

 Blanchard of the Faculty of Medecine of Paris and Mr. F. V. 

 Theobald, we have become possessed of a number of specimens of 

 the European Anopheles inaciilipennis Meig. These abundantly estab- 

 lish our contention of the distinctness of this form from any of the 

 American species. Maciilipennis is nearer to the Californian occiden- 

 talis D. & K. than to the Eastern quadrimaculatus Say, but lacks the 

 apical yellowish wing spot characteristic oi occidentalis. 



Genus CULEX Linnaeus. 

 Culex toweri, new species. 



Head behind the eyes margined with silvery gray ; thorax clothed with rather 

 pale yellowish brown scales above with faint traces of dorsal stripes ; abdomen entirely 

 black above, beneath with white lateral basal spots and a pale median area. Wings - 

 with the veins and fringe dark brown scaled. Hind legs black with the first to fourth 

 tarsal joints narrowly white ringed at both ends, fifth joint white ringed at the base ; 

 knees white tipped, tibiee rather broadly white tipped ; on the first and second pairs 

 of legs the annulations are much reduced. Proboscis and palpi black. 



39 specimens, Mayaguez, Porto Rico (W. V. Tower). 

 Type. — Cat. no. 10222, U. S. Nat. Mus. 



The larva falls with Culex lanientator D. & K. in the table and is 

 much like it, but the adults are quite distinct. 



Culex fur, new species. 



Proboscis black ; head broad, black behind the eyes; thorax with the anterior 

 half covered with brassy scales, two large dark patches within this area on the disk 

 before ; posterior half of the thorax deep brown. Abdomen black above, the hind 

 margins of the segments with yellowish hairs ; beneath dirty gray. Legs black. 

 Wings brown scaled along the \eins, the scales on the apical portion broad. Tarsal 

 claws simple. 



One specimen, Q) Colon, Panama (A. C. H. Russell). 

 Type. — Cat. no. 10259, U. S. Nat. Mus. 

 The larva is unknown to us.
