as a variety of H. scapularis, have the face decidedly whitish 

 instead of dark ochraceous as in the type; they are, however, 

 identical in other respects. San Francisco and Rivera, Cali- 

 fornia. 



Parydra appendieulata Low. Apparently identical with 

 the type. Berkeley. 



Seatophila hamifera Becker. Although representatives 

 of this genus have not before been found in this country, 

 there seems to be no doubt but that the specimens before me 

 belong here. The macrochfptal pattern of the thorax, the 

 larger opening of the mouth, the sparse hairing of the face, 

 and the fact that the costal vein ends at the third longitudi- 

 nal point uinnistakably toward Seatophila. The coloration 

 of the various parts, the peculiar color pattern of the thorax 

 above, as illustrated by Professor Becker {Berl. Ent. Zeit., 

 Vol. XLI, Taf. V, Fig. 11) and the number and position of the 

 wing spots, mark our specimens as identical with the Norwegian 

 Hcatopliila luimifera. Alameda, California. 



Caenia bisetosa Coquillett. Redlands, California. 



LITERATURE. 



The following bibliography of the family Ephydridae is 

 primarily concerned with systematic works, but includes also 

 all available references to insects in recognized genera. The 

 method of reference carried out in the catalogue of species 

 which follows consists of placing the date first, then the initial 

 of the author, and finally the page reference. There are several 

 eases in which similar initials occur at the same date, but in 

 every such ease the page reference Avill enable one to determine 

 which author is referred to.
