In addition to the type, which is a male from Indiana reared 

 from Crambus zeeJlus Fernald, the United States National Museum 

 has specimens from Virginia, Tennessee, Indiana, and Pennsylvania, 

 as well as some without locality data. Hosts recorded for specimens 

 among this material include Cramhus mutahUis Clemens, C. trisectits 

 Walker, and C. zeelhis Fernald. 



5. MACROCENTRUS TERMINALIS (Ashmead), new combination 



Zele terminaUs Ashmead, Proc. U. S. Nat. Mus., vol. 11, p. 652, 1888. 



Type. — In the United States National Museum. 



This species, which is known only in the male, is very similar to 

 pyraustae^ differing, however, in having the metapleurum and propo- 

 deum even more completely and more strongly sculptured, in the 

 roughened prepectus, in having the basal abdominal tergites yel- 

 low, in the broader face, and in the longer malar space, which is 

 about as long as the clypeus. 



Face nearly twice as broad as long to base of clypeus ; eyes small ; 

 temples and cheeks somewhat rounded; antennae usually 38 to 42 

 segmented; scape, in the male, somewhat swollen; longest segment 

 of maxillaiy palpus hardly as long as second segment of antennal 

 flagellum; labial palpi much longer than face, the apical segment 

 much lengthened; notauli foveolate; metapleura completely rugu- 

 lose; propodeum coarsely reticulate; apical teeth of trochanters 

 weak, indistinct ; first discoidal cell very long ; mediella about twice 

 lower abscissa of basella; first abdominal tergite at least a third as 

 long as the abdomen, longitudinally aciculate, the spiracles much 

 farther from base than from each other; sculptured part of second 

 tergite somewhat constricted at the middle; legs, as well as scape 

 and pedicel, deep honey-yellow. 



The above notes are based on the type, which is from Missouri; 

 on five additional collected specimens in the national collection 

 from Illinois, Minnesota, New York, Pennsylvania, and Massachu- 

 setts, respectively; and on three specimens, in the Philadelphia 

 Academy of Natural Sciences, from New Jersey and Illinois. The 

 specimen from New Jersey has the thorax almost entirely yellow. 



6. MACROCENTRUS LONGICORNIS Provancher 



Macrocentrus longicoinis Provancher, Nat. Can., vol. 12, p. 173, 1880. 



Type. — In the Museum of Public Instruction, Quebec, Canada. 



I have not seen the type of this species, but in the collection of the 

 United States National Museum there are three specimens from 

 Cleveland, Ohio, and one from Itasca State Park, Minn., which ap-
