Ty'pe locality. — Colorado. 



Type.—Cs^t. No. 24966 U.S.N.M. 



Described from three female specimens labeled "Colo., Collection 

 Ashmead." One of the paratypes has 47-segmented antennae; the 

 other specimen has the antennae broken. 



There are in the national collection three other female specimens 

 of this species, which were not included in the type series : one from 

 Texas; one labelled ''Wellington, Kansas, E. G. Kelly, Exp. No. 

 151539"; and one collected by E. S. Southworth, at New Salt, New 

 York, July 16, 1903. 



5. METEORUS RETICULATUS, new species. 



Resembles maximus, but is much smaller; it differs further in its 

 mostly fuscous antennae and in the posterior tarsi being testaceous or 

 ferruginous rather than white. 



Female. — Length 5.5 mm. Face about as broad at base of clypeus 

 as long, weakly punctate, shining; eyes large, the malar space very 

 short, as in maximus; antennae 39-segmented, the first and second 

 flagellar segments of equal length; ocell-ocular line equal to greatest 

 diameter of an ocellus; thorax slender; parapsidal grooves well de- 

 fined; mesonotal lobes smooth and shining; propodeum reticulated, 

 the interstices large and smooth, shining; in the type there are two 

 short transverse basal areas and two rather large median areas mod- 

 erately well defined; median longitudinal carina on propodeum more 

 or less distinct; propleura closely punctate, the depression crenu- 

 late; mesopleura punctato-regulose on lower half, smooth and pol- 

 ished above; wings as in maximus, except that in the type the ner-
