received specimens, it was first noted in Honolulu on domestic 

 pigeons in October, 1910 (Proc. Hawaiian Ent. Soc, vol. 2, 

 1912, p. 188). Mr. E. M. Ehrhorn reported that the species 

 had become very common on the pigeons in Honolulu by De- 

 cember. 1911 (1. c, p. 206). 



DESIGNATIONS OF MUSCOID GENOTYPES, WITH 

 NEW GENERA AND SPECIES 



BY CHARLES H. T. TOWNSEND 



The writer has recently completed a critical catalogue of all 

 the generic names that have been proposed in the Muscoidea, 

 embracing the world's fauna, recent and fossil, with validly 

 designated genotype for each. Although the subject has been 

 fully elaborated to include, among other things, the actual sense 

 of the authors concerned so far as possible to determine same, 

 ascertained at a cost of great labor, especially translating 

 Brauer and Bergenstamm's sense throughout, and would thus 

 be very useful for reference, yet its publication at this time 

 would avail comparatively little else on account of the large 

 number of nomenclatorial cases involved for which there are 

 as yet no rules or decisions of the International Commission 

 to cover, and which must be left open for future ruling. The 

 designations of genotypes for those genera with status as yet 

 unsettled will occupy but little space ; they are given in the 

 present paper, together with a few new genera and species that 

 are necessary in order to validate certain designations and 

 establish the sense of authors concerned. 



The great majority of muscoid genera are monobasic, and 

 a very large part of the remainder already possess validly 

 designated genotypes. Less than 140 muscoid generic names 

 remain without designations or with designations whose 

 validity is at all doubtful. The writer has personally verified 

 all the genotype designations of Latreille (1810), Curtis 

 (1826-38), Macquart (1834-43), Westwood (1840), Blanch- 

 ard (1840), Zetterstedt (1844), Rondani (1856), Desvoidy 

 (1863), Brauer and Bergenstamm (1889-94), Brauer (1893),
