Antennae black, third joint with a brown sheen. Thorax and scutelhun 

 ashy-brown pollinose, more or less silvered in oblique view; vittae black 

 with wide brown borders, the whole of the three vittae changeable to 

 brown in front view. Abdomen black, pale brownish to silvery pollinose, 

 a wide black median vitta, the hind borders of segments more blackish 

 or subshining. Legs black. Wings clear, with narrowly clouded cross- 

 veins. Tegulae whitish, with pale fuscous borders and yellowish edges. 



Holotype, No. 20,949 U. S. N. M. 



This striking genus is named as a tribute to the memory of that en- 

 thusiastic, capable and indefatigable Italian naturalist, Antonio Raimondi, 

 who penetrated nearly every corner of Peru during his residence of nine- 

 teen years in that country, and who has left us in his work " El Peru " a 

 detailed account of his early ambitions and subsequent travels, told in a 

 style that is charming in its simplicity and directness. 



Cistudinomyia new genus. 



Genotype, Sarcophaga cistudinis Aldrich, op. cit., 278-80. 



Differs from Sarcophaga as follows: Striking head profile of Eutheresia 

 and Paratheresia, the vibrissal axis much shorter than antenna! axis and 

 equal to about two-thirds head-height. Clypeus broad and short, the 

 carina more or less distinct ; epistoma much narrowed by vibrissal angles 

 and well projected below them. Facialia strongly arcuate, considerably 

 flattened. Proboscis little over half head-height. Third antennal joint 

 one to one and a half times second. Arista thickly long-plumose practi- 

 cally to tip. Male vertex almost as wide as eye, that of female nearly or 

 more than one and one-fourth times eye, the front strongly bulged in 

 profile. Frontals thickly placed, not divergent, stopping at base of an- 

 tennae. Outer verticals developed in male. Frontalia broader than one 

 parafrontal in middle and distinctly narrowing posteriorly in both sexes. 

 Parafacialia scarcely narrowed below, about as wide as frontalia, with 

 two or three irregular rows of very fine hairs or only scattered hairs. 

 Cheeks of female nearly three-fifths eye-length, those of male over half 

 same. Sternopleurals three to six, normally four. Postsuturals two, 

 with two to four short bristles in front. None of male tibiae villous. 

 No median macrochaetae on second abdominal segment, a marginal row 

 on third and anal segments in both sexes. Male hypopygium small, with 

 small forceps. First hypopygial tergite of female entire, showing a 

 strongly arcuate outline. 



This most interesting form, which is far removed from the Sarcophaga 

 type, is evidently a true parasite confined to the box-turtle. 



Eutheresiops new genus. 



Genotype, Eutheresiops trixoides n. sp. 



Differs from Eutheresia as follows : Vertex about as wide as eye. Fron- 

 talia broader; parafacialia nearly as broad as anterior end of frontalia, 

 and bearing a small patch of hair below next orbit. Cheeks over one- 

 half eye-length. Eyes hairy. Antennae shorter, third joint two to two
