170 FIRST ANNUAL REPORT OF THE STATE ENTOMOLOGIST. 



MiiscidcB is showu iu Fig, 4G, drawn from CalUphora voniitoria, the 

 common blue meat-fly of butclier's-stalls and occasionally of our 

 houses. The references to veins and cells are the same as in the pre- 

 ceding figure. From a comparison of the two it will be seen that 

 they differ mainly in the shape of the first posterior cell, d, which in 

 the A7ithomyiidiB is quite open, instead of being nearly closed at the

wiug-margin, as in Muscidm, by the sudden bending up of the fourth 

 longitudinal vein when near the margin, and running obliquely up- 

 ward to very near the termination of vein 3. 



The Anthomyiidm are further distinguished by a transverse suture 

 (impressed line) crossing the thorax, and by their tegulae (the covering 

 scales of the spiracles of the hinder thorax) being rather well-developed, 

 although frequently not very large in size. 



The Anthomyiidffi an Extensive Family. 

 The family is a numerous one. Baron Osten Sacken, in his Catalogue,* 

 records one hundred and thirty-nine North American species (includ- 

 ing above fifty of Walker's unrecognized species), belonging to twenty 

 genera. Later, Mr, E. 11, Meade, of England, who has been making 

 special study of the family, has enumerated one hundred a,nd forty- 

 one species, in nineteen genera, from material sent to him from the 

 Museum of Comparative Zoology at Cambridge, Mass.,t which, with 

 others in the Museum not seen by him, and those to be noticed in the 

 present report, gives, so far as recognized at the present, one hundred 

 and thirty-six North American Antlioniyiidce. Of these, no less than 

 thirty-five species are accepted as identical with European ones.
