Culex (Carrollia) bonnei, new name. 



Dr. and Mrs. Bonne identified the species of Carrollia found 

 by them in Surinam as iridescens Lutz. The Carrollia forms 

 appear to be very local, as witness the marked differences be- 

 tween secunda from Panama and metempsyta from Costa 

 Rica. Hence this identification of iridescens Lutz of Brazil 

 appears to be doubtful, and I propose to fix the Surinam form 

 with the name bonnei. The male genital structures of the true 

 iridescens have not been described. 



A male and two females are before me, to which I have 

 attached the U. S. Nat. Mus. type No. 24862. 



Haemagogus anastasionis, new species. 



Male hypopygium: Side piece three times as long as wide, 

 the tip conical ; a hairy lobe at inner base ; many scales on 

 inner margin; clasper moderate, the terminal spine nearly 

 half its length ; claspette straight, rather stout and of moderate 

 length, densely hirsute inwardly and with a seta at outer third ; 

 terminal filament short, sickle-shaped, ribbed. 



Male and female : With blue and green luster ; margins of 

 prothoracic lobes, pleurae and sides of abdomen silvered ; 

 dorsal silver spots, most distinct on sixth and seventh seg- 

 ments ; posterior segments black ventrally and projecting ; 

 legs black with blue reflection, the vestiture a little shaggy ; 

 femora silvery below at base. 



Types, two males and six females. No. 24864, U. S. Nat. 

 Mus.; Puntarenas, Costa Rica, July 15, 1921 (A. Alfaro). 



NOTE ON MELANOCONION INDECORABILIS 

 THEOBALD 



(Dipt era, Culicidce) 



By HARRISON G. DYAR 



Theobald (1903) described Melanoconion indecorabilis from 

 Para, Brazil, from three females and one male. The latter he 

 was not sure belonged to the same species, and he could not 

 separate it from the male of his M. humilis. The females
