be added in the future, but such can more easily be recognized 

 when the known ones are tabulated. 



I have given the groups of Schiner family rank to which I 

 believe they are entitled. 



As to the larval habits of the Calyptrata the general state 

 ment can be made that they are parasitic, pseudo-parasitic, 

 creophagous, necrophagous, coprophagous and vegetarian. 

 The sub-sections may be summarized as follows : Mammophilcz, 

 parasitic exclusively on mammals ; Entomopkiltz> parasitic ex 

 clusively on other insects (Lepidoptera, Coleoptera, Hemi- 

 ptera, Hymenoptera, Orthoptera); Creophilce, including all 

 the true flesh flies, some species being pseudo-parasitic on 

 mammals, others coprophagous, some even parasitic in lepi- 

 dopterous larvae, and a few breeding in vegetable matter ; 

 Anthophilce, breeding as a rule in decaying vegetable matter, 

 but being also largely coprophagous and even parasitic. 



TABLE OF FAMILIES. 



Super-family MUSCINA. 



Section MUSCID^ CALYPTRAT^. 



1. Mouth parts rudimentary, wanting or deeply sunken ; palpi rarely 



present ; vibrissae and macrochaetae absent ; apical (first pos 

 terior) cell wide open, narrowed, or closed and petiolate ; usually 

 piliferous flies (subsection Mammophilce} ............ fain. CEstridae 



Mouth parts well developed ; palpi rarely wanting ; vibrissae present ; 

 bristly or bare ; never piliferous flies ....................................... 2 



2. Fourth longitudinal vein bent up toward the third, forming an apical 



cross- vein, thus closing or more or less narrowing the apical cell.. 3 



Fourth longitudinal vein straight, the apical cell wide open, not nar 



rowed in the border (subsec. Anthophilce) ...... fain. Anthomyiidae 



3. Arista naked,* or with only a very delicate and usually scarcely per 



ceptible pubescence (subsec. Entomophilcc] ............................ 4 



Arista distinctly hairy and usually feathered (subsec. Creophilcz] ...... 8 



4. Abdomen almost naked or with irregular, short, bristly hairs, never 



with long, regularly arranged macrochaetae (true or stout 

 bristles)f ..... ....................................................................... 5 



* Rhynchomyia and Gymnostylina, European genera usually classed 

 with the Muscidcs s. sir., have a nearly naked arista ; they have not yet 

 been recognized in this country. On the other hand, some genera of 

 TachinidcE s. sir. have the arista very distinctly pubescent but not hairy. 



f Miltogramma and some allied genera, of the Tachinidcs s. sir., are 

 without macrochaetae ; but they all have a short conical, arched abdo 

 men, and may thus be distinguished from the Gymnosomatida', which 

 have the abdomen spherical.
