vein has spines at its base only. The dorsal sin-face of the squamula 

 thoracalis is hairy . 



The species known to nie which belong here are : vomitoria 

 "L., erythrocephala Meig., violacea Meig., anthmcina Meig., 

 latifrom nov. sp. and ni.gr ibticca nov. sp., which is, perhaps, 

 only a variety of erythrocephala. 



Lucilia. Type L., camar L, Thorax not flattened caudad the 

 transverse suture. In any species the number of posterior dorsocen- 

 trals and achrosticals is constant and both series consist of well de- 

 veloped macrochsetse. The genas seen witb an amplification of 

 twenty diameters are absolutely naked. The spines of the third 

 longitudinal vein are not limited to the extreme base, but extend 

 well along the vein toward the small cross vein, say from two fifths 

 to three quarters of that distance. The dorsal surface of both 

 squamulae is bare. 



The species of Lucilia known to me are: cct'scir L., wrieat.a 

 Meig., nobilis Meig., sylraritm Meig. and spinicosta Hough. 

 Phormia Type Phormia regina Meig. Thorax somewhat flattened 

 caudad the transverse suture. In any species the number of posterior 

 dorsocentrals and achrosticals is inconstant; moreover, the macro- 

 chaeta? of each series are notequally well developed, the most caudad 

 being much the largest, and each succeeding one, as we passcephalad 

 along the series, being usually smaller until the last one or two are 

 so small as to be distinguishable with difficulty or not at all fi-om 

 the surrounding- microchaetae. The geuae seen with an ampli- 

 fication of twenty diameters are distinctly hairy. The spines of the 

 third longitudinal vein are not limited to tne extreme base, but 

 extend, roughly speaking, half way to the small cross vein The 

 dorsal surface of the squamula thorcalis is bare. 



The species of Phormia known to me are: ret/hut Meig. and 

 grintJamlica Zett. 



ProtocaJlt'i>li<ii-(i. Type P. azurea Fall. Thorax somewhat flat- 

 tened caudad the transverse suture. The number of posterior dor- 

 socentrals i> f urly constant, though not so absolutely invariable in a 

 species as in Lucilia and Calliphorn ; eich macrochaetse of the series 

 is well developed and all are of about the same size The posterior 

 achrosticals are less well developed than the dorsocentrals, are va- 

 riable in number in the same species and even on the two sides of 

 the same specimen; in any specimen they may vary in si/e, these 

 farthest cephalad being smallest. Thegenae seen with an amplifi- 

 cation of twenty diameters are distinctly hairy, the hairs being 

 much coarser than in Phormia or ( '/t/'i/i/iora. The spines of the 

 third longitudinal vein are not limited to the extreme base, but ex- 

 tend about balf way to the small cross vein. The dorsal surface of 

 both squamnUe is bare. 



I am acquainted with two species of this genus: .:ur<' 

 Fall, and chri/Horrhwa Meig.
