NAMES AND SYNONYMY IN ANOPHELES 15 



ferruginous, marked with black near the apex ; tarsi basaDy ferru^nous. 

 the second joint partly and all of the last three black ; hind tibiae less flat- 

 tened and more abruptly bent than in Q. sylvicola. Wings hyaline, a 

 trace of infuscation apically in the costal region, along the submarginal cell 

 and at upper end of anterior crossvein. 



Length : Body about 8 mm., wing 7.5 mm. 



Costa Rica, bred from epiphytic bromeliads (C. Picado) ; one female. 



Type: Cat. No. 15504, U. S. Nat. Mus. 



Three localities are given in the memorandum of Mr. Picado accom- 

 panying the single specimen. These are : Orosi, 1 , 1 00 meters (Novem- 

 ber to January) ; Cartago (September) ; Estrella (September). 



The specimen is in poor condition, having been preserved in spirits, 

 and, smce being mounted, attacked by Dermestidae. The specimen is 

 much more pubescent than the species just described from Peru, but this 

 latter specimen is obviously somewhat worn. 



It is possible that the Mallota championi of Williston, already men- 

 tioned in the generic discussion, is the male of the species here described, 

 but this can not be decided without study of the type, as even the generic 

 position cannot be satisfactorily determined from the description. 



This is an appropriate occasion to record the occurrence of syrphid 

 larvae, of the Eristalis or " rat-tailed " type, in epiphytic Bromeliaceae. 

 They were found by the vmter at Cordoba, Mexico, in March, 1 908. 

 These larvae were creamy white with an extremely long and slender 

 respiratory filament. They occurred abundantly in the water held by 

 the leaf-bases of bromeliads growing high up on the branches of a large 

 mango tree. Unfortunately circumstances prevented my rearing these 

 larvae. Whether these larvae belong to the genus here described or to 

 the genus Eristalis itself, future investigation must decide. 



NAMES AND SYNONYMY IN ANOPHELES 



(Dipiera, Culicida) 

 By FREDERICK KNAB 



In 1908 (Proc. U. S. Nat. Mus., vol. 35, p. 53) Dr. Dyar and the 

 writer proposed the name Anopheles critzii for the species described by 

 Theobald as Anopheles lulzii in 1901 (Mon. Culic, vol. 1, p. 177). 

 that name having been already applied to a different species by Cruz 

 earlier in the same year (Brazil Medico, vol. 15, p. 423). Recently,
