 No. 5103, same collector, Bureau of Entomology, U. S. Department 

 of Agriculture. 



Named for W. J. Phillips. 



Genus CHELONUS (Jurine) Panzer. 



CHELONUS SHOSHONEANORUM, new species. 



Female. — ^Length 2.5 mm. Antennae 16-jointed. Compared with 

 the type of C. lavernse Ashmead, its nearest or at least one of its 

 closest relatives, it differs as follows : Reticulations of posterior half 

 of dorsulum smaller than the fovese at base of scutel, the latter with- 

 out a row of fovese or reticulations along the lateral margin, nearly 

 smooth and pohshed; central area on dorsal aspect of propodeum 

 nearly quadrate and with only one carina and this a median one 

 extending from the anterior edge of the area to near the middle, 

 posterior face of propodeum bounded above by a carina that is pro- 

 duced in four places into flattened tubercles much as in Ascogaster 

 cari^ocaiosx, except that the median prolongations are nearer to each 

 other than to the lateral prolongations; stigma fuscous, veins mostly 

 infuscated, liind tibige almost entirely testaceous. 



Tyjye-locality. — Colorado Springs, Colorado. 



TyiJe.^Cat. No. 13340, U.S.N.M. 



One specimen labeled Ex Quercus, April 2, 1910, E. Bethel, collector, 

 and probably parasitic on Argyresthia, sp. 



Genus APANTELES Foerster. 



APANTELES (APANTELES) BETHELI, new species. 



Female. — ^Length, 2.25 mm. Similar in many points to A. canarsise 

 Aslmiead, from the type of wliich it differs essentially as follows: 

 Antennae entirely black, palpi inclining to testaceous; tegulae and 

 wing base blacldsh, stigma and veins mostl}^ more or less fuscous, mid 

 legs mostly black or blackish, propodeum dullish, the septa forming 

 the nearly complete areola supplemented on each side by an incom- 

 plete lateral longitudinal carina, wliich lies nearer the lateral edge of 

 the propodeum than to the median carinas; first dorsal plate tmce or 

 almost twice as long as wide in the middle, nearly as wide at apex as 

 at base, gently arched, its apical two-thirds rugose tliroughout and dull- 

 ish, its apical half divided longitudinally by an oval, shallow fossa that 

 extends nearly to the apex, the greatest transverse width of this fossa 

 is one-third or nearly one-third the vndih of the first dorsal plate at 

 its apex, sides of the second plate forming a trapezoid that is twice as 

 wide at base as long down the middle and nearly three times as wide 

 at apex as long down the middle, second plate dulhsh rugulose and a 

 httle less than half as long as the next dorsal segment measured down 

 the middle, third dorsal segment smooth, polished, and impunctate.
