nized in the Culicinae by the pronounced angle frequently present 

 near the more or less perfect^fusion of their two segments or 



pseudosegments. These organs are ven- 

 tral, submedian, with bases approximate. 

 They are, if we have correctly homo- 

 logized the parts, highly specialized in 

 the Anophelinae, in which group they 

 are linear, approximate and usually bear 

 several divergent, spiny apical processes. 

 These organs are remarkably diverse in 

 structure and in Culex, as now restricted, 

 are divided. The terminal falcate blade 

 so conspicuous in Culicada appears to 

 arise from near the base of the setaceous 

 proximal portion. This latter is smooth 

 and usually with its apex crowned with 

 a dense series of stout, chitinous spines, 

 very characteristic of Culex, and pre- 

 sumably occurs in all species, though
