APmOCH^fflTA RUSTICATA, new species. 



Female. — Black, shining; frons distinctly broader than long, only 

 a few scattered fine hairs besides the bristles present, lower post- 

 antennal bristles three-fourths as large as upper pair, situated as in 

 table, center pair in first row nearer to outer pair than to post- 

 antennals and very little below the former which are if anything a 

 trifle below the post-antennal pair transversely, antennae of rather 

 more than the normal size, arista one and one-half times as long as 

 frons, slightly pubescent, palpi black, of rather large size and strongly 

 bristled; thorax shining, lower half of pleurae glossy; abdomen dull 

 black, segments subequal, numerous scattered short hairs on all 

 segments, legs black-brown, no distinct hind tibial setulae, wings 

 brownish, thin veins distinct on disk but indistinct at near margin,

Female, Corvallis, Oregon, May 5, 1896 (332). (No collector's 

 name.) 



APmOCIL£TA PERPLEXA, new species. 



Female. — Very close to rusticata but smaller and deeper black, the 

 halteres are black and the legs entirely so in the type ; the hind tibiae 

 have the hairs on the postero-dorsal surface more distinct and the 

 ridge more pronounced than rusticata; the abdomen is also nearly 

 bare and the long hairs on ovipositor and ventral surface at tip are 

 not distinct in perplexa. I had originally put one specimen along 

 with the type of rusticata with some doubt, but a second specimen I 

 have since discovered has caused me to change my table as it is 

 quite evidently distinct from that species. It is unfortunate that
