vein has spines at its base only. The dorsal surface of the squaraula 

 thoi-acalis is hairy. 



The species known to me which belong here are : vomitoria 

 L., erythrocephala Meig., violacea Meig., anfhracina Meig., 

 latifrons nov. sp. and nigribucca nov. sp., which is, perhaps, 

 only a variety of erythrocephala. 



Lucilia. — Type Ij.,caisar L, Thorax not flattened cau dad the 

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

 trals and achi'osticals is constant and both series consist of well de- 

 veloped macrochaetae. The genae seen with 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: ccesar L., sericata 

 Meig., nobilis Meig., syharum Meig. and spinicosta Hough. 

 PAormm— Type Phormia regina Meig. Thorax somewhat flattened 

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

 dorsocentj'als and achrosticals is inconstant; moreover, the macro- 

 chaetae of each series are notequally well developed, the most caudad 

 being much the largest, and each succeeding one, as we pass cephalad 

 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 from 

 the surrounding microshastae. The genae seen with an ampli- 

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

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

 extend, I'oughly speaking, half way to the small cross vein The 

 dorsal surface of the squamula thorcalis is bai-e. 



The species of Phormia known to me are : regina Meig. and 

 grcenlandica Zett. 



ProtocalUphora. — Type P azwreaFall. Thorax somewhat flat- 

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

 socentrals is fairly constant, though not so absolutely invariable in a 

 species as in Lucilia and Calliphora ; exch macrochaetae 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 size, these 

 farthest cephalad being smallest. Thegenas seen with an amplifi- 

 cation of twenty diameters are distinctly hairy, the hairs being 

 much coarser than in Phormia or Cal'iphora The spines of the 

 third longitudinal veinai-e not limited to the extreme base, but ex- 

 tend about half way to the small cross vein. The dorsal s\n'face of 

 both squamulae is bare. 



I am acquainted with two species of this genus: azurea 

 Fall, and chrysorrhcea Meig.
