closely set bristles, a short row of anteroventral bristles toward 
apex, and a partial row of long posteroventral bristles toward 
base; hind tibia with a dorsal subapical bristle, two anteroven- 
tral bristles toward middle, and two posterodorsal bristles to- 
ward middle; claws and pulvilli small. 
Wing hyaline; remigium below with a few setulae at base; 
only third vein setulose; fourth vein bent toward anterior 
margin of wing at 90 degrees, the angle slightly rounded; 
apical cell open; anterior cross vein strongly oblique and at 
or but slightly beyond middle of second section of fourth vein; 
posterior cross vein doubly arcuate; last section of fifth vein 
one-fifth as long as preceding section; seventh vein short and 
curved; lower squamal lobe ovate, wide behind, pilose above in 
depression and anteriorly. 
Abdomen with ventral membrane narrowly exposed in fe- 
male; no discal or median marginal bristles on intermediate 
segments; third and fourth segments each with weak and re- 
eumbent bristles in marginal row. 
Genital segments large, globose, the first rather flattened. 
The generic name Callitroga is validated by Brauer (1883) by 
citation in specific synonymy. The genotype must be selected 
from one of the three names originally associated with it, namely 
Calliphora anthropophaga Lesbini, Weyenbergh and Conil, 
Compsomyia macellaria (Fabricius) and Lucilia hominworax 
Coquerel. The only information pertinent to this problem is 
that presented by Brauer (1883). This is as follows: ‘‘Calliphora 
anthropophaga Lesbini, Weyenbergh et Conil. ‘Myiasis’ Act. 
Acad. Nat. Buenos Aires, T.III. Entr. 2. 41-98. Arch. d. Zool. 
experimental. T.9. 289 (Conil) Ann. d. Scien. naturell. 6, ser. 
T. X. Nr. 4 = Compsomyia (Rond. 1875) macellaria F. conf. 
Lucia homimvorax Cog. (Lucila O. S8., Callitroga Sch., Musca 
olim.) E. Lyneh Arribalzaga, Anales de la Sociedad cientifica 
argentina. Tome X. p. 70-84.’’ 
Under Article 25, as interpreted by Opinions 1, 4, and 53 of 
the International Commission, Callitroga is validated although 
merely cited in synonymy. Townsend (1915) considered it in- 
valid but later admitted its validity. It must be noted that since 
Brauer, in the publication cited, deals with species and not, with 
genera as such, the synonymy cannot be regarded as generic. 
In other words, it cannot be considered that Callitroga is here 
synonymized with Calliphora, Compsomyia, Lucilia, or Musca, 
but that the species which Brauer here calls Compsomyia (F.), 
with its synonyms Calliphora anthropophaga Con., and Lucilia
