DESCRIPTIONS OF SOME NEW MOSQUITOES FROM 

 TROPICAL AMERICA. 



By Harrison (r. Dyab and Frederick Knab, 



Of the U. S. Department of igriculture. 



The following new species have been recognized among the material 

 collected for study in the preparation of the forthcoming monograph 

 of Culicidae by Dr. L. (). Howard and the present authors. 



ANOPHELES CRUZII, new name. 



We propose this name to replace Myzomyia lutzii Theobald, which 

 is preoccupied by Myzorhynchella lutzii Cruz, since we do not recog- 

 nize either Myzomyia or Myzorhynchella as distinct from Anopheles. 

 We note further the existence of Manguinhosia hit-,} Peryassu, which 

 will also require a new name, if.it prove, as we now suppose, that the 

 new genus Manguinhosia is not separable from .1 n<>ph< les. h 



It gives us much pleasure to dedicate this interesting species to 

 Dr. Oswaldo Cruz, the well-known hygienist and bacteriologist of 

 Rio de Janeiro. 



The larva has been discovered by Mr. A. IT. Jennings in the 

 Panama Canal Zone, living in the water between the leaves of 

 bromeliaceoiis plants, which appears to he its only habitat. 



AEDES EPACTIUS, new species. 



Female. — Proboscis long and slender, black; palpi entirely black- 

 scaled; vertex of the head anteriorly with broad whitish scales, pos- 

 teriorly with darker scales: thorax deep brown-scaled, with slight 

 bronzy luster and with whitish markings: these marking- consist of 

 two very broad outcurved bands on the anterior half of the meso- 

 notum. which become approximated and narrowed at the middle, and 

 run parallel with each other to the scutellum; the sides of the meso-

 of the author of the paper here cited.
