BRUES: PARASITIC HYMENOPTERA. 69 



narrower toward the tip, the second section of the radius twice the length 

 of the first; median and suhmedian cells of equal length or nearly so, the sub- 

 median being indistinctly the longer. Discocubital vein strongly curved in- 

 wardly at the base, without stump of a vein. Transverse cubitus less than 

 one-half as long as the distance from it to the insertion of the second recurrent 

 nervure; discoidal nervure broken just above the middle. Legs moderately 

 stout, the posterior femora thickened; tarsi slender. 



One specimen, seen in side view, with the front wings very finely 

 preserved, but the body only moderately so. 



Type.— No. 2250, M. C. Z., Florissant, Col. (No. 9290, S. H. 

 Scudder Coll.). 



In Szepligeti's arrangement of the Ophioninae (Genera Insectorum, 

 fasc. 34) this species can be readily traced to this genus, with which it 

 appears to agree in all essential particulars. 



Anomalon Gravenhorst. 



Key to the Florissant species of Anomalon. 



1. Submedian cell longer than the median by one-third the length of 



the transverse median nervure ; second recurrent nervure inserted 

 the length of the transverse cubitus beyond the tip of the cubito- 



discoidal cell A. confertum, sp. nov. 



Submedian cell not or indistinctly longer than the median ; recur- 

 rent nervure inserted nearer to the tip of the cubitodiscoidal cell 



2. 



2. First recurrent nervure received just before the basal third of the 



discocubital cell, wings infuscated, brownish. 



A. deletum, sp. nov. 

 First recurrent nervure received nearer to the middle than to the 

 basal third of the discocubital cell, wings hyaline. 



A. excisum, sp. nov. 



Anomalon confertum, sp. nov. (Fig. 52.) 



Length 9-14 mm. Dark colored, the abdomen no lighter than the head and 

 thorax. Wings hyaline. Head above polished, shining, but the projecting 

 lower portion (probably the face and clypeus) is transversely rugose. Meso- 

 notum shining, faintly shagreened, with plainly marked parapsidal furrows 

 which meet in a deeply impressed transverse depression at the base of the 

 scutellum; scutellum strongly elevated, pyramidal, strongly punctate. Meta- 

 notum with four equidistant longitudinal carinae that extend less than half
