BKUES: PARASITIC HYMENOPTERA. 71 



segment rather suddenly enlarged at the tip, only a little more than 

 one-half as long as the second, which is very gradually widened apically, 

 until the tip is one-half wider than the base. Beyond this it is rather 

 suddenly broadened. Legs stout; the posterior femora clavate, the thickened 

 apical part twice as long as the slender basal portion and one-fourth as 

 wide as the length of the femur. Posterior tibiae at tip three-fourths as 

 thick as the broadest part of the femur. Metatarsus thickened. Wings 

 hyaline; stigma and veins piceous, the former very slender; marginal cell as 

 long as the discocubital; submedian cell very little longer than the median; 

 discocubital nervure faintly arcuate inward, nearly straight; first recurrent 

 nervure received a short distance before the middle of the discocubital cell; 

 second, half the length of the transverse cubitus beyond its tip. Transverse 

 median nervure of hind wing broken a short distance below the middle. 



Type.— No. 2255, M. C. Z., Florissant, Col. (No. 8697 and 8765 

 (reverse) S. H. Scudder Coll.). 



Anomalon deletum, sp. nov. 



Female. Length 8 mm. Ovipositor 2.5 mm. Black, the abdomen reddish 

 brown; front and middle legs brownish yellow; wings with a strong brownish 

 tinge. Antennae long and many jointed, but more nearly of an even thick- 

 ness throughout than in recent species of the genus. They have apparently 

 something over 40 joints and are not attenuated at the tip, the apical joint 

 being as wide as the preceding ones and somewhat longer, the latter each 

 about twice as long as thick; basal joints no thicker, but longer, three or four 

 times as long as thick. Head smooth, mandibles brown. Mesonotum very 

 finely sculptured, nearly smooth; metathorax not well preserved; first ab- 

 dominal segment gradually enlarged to the tip, very finely longitudinally 

 striated on its posterior half; second one-half longer than the first, but little 

 broadened toward the tip; third enlarged, following as usual. Ovipositor 

 longer than usual. Legs stout, the posterior tibiae thickened, with a long 

 spur. Wings brownish, stigma and veins fuscous, the former narrow, lanceo- 

 late; discocubital cell distinctly longer than ths marginal, its discoidal side 

 arcuately curved inwardly; first recurrent nervure received just before the 

 basal third of the cubitodiscoidal cell; second, one-third the length of the 

 transverse cubitus beyond its tip; submedian cell not or indistinctly longer 

 than the median. 



One specimen, well preserved in lateral aspect. 

 Type.— No. 2256, M. C. Z., Florissant, Col. (No. 11,481, S. H. 

 Scudder Coll.).
