INSECUTOR INSCITI^ MENSTRUUS 119 



Types, Cat. No. 20006, U. S. Nat. Mus., two pairs on sep- 

 arate tags and a slide bearing male and female heads, female 

 hind tibiae, and a female fore wing. 



Sympiesis marilandica, new species. 



Female. — Somewhat of the same stature, etc., as Sympiesis 

 guttatipennis but differing from the type of that species as fol- 

 lows : The last two pairs of coxae are white and the last two 

 pairs of femora are only dusky in the middle laterad ; the dor- 

 sal aspect of the basal half of the abdomen is lemon yellow ex- 

 cept across the base (broadest), along the margins, along the 

 median line very delicately, a faint cross-stripe a little out from 

 the base of the yellow ; the ventral aspect is similarly yellow 

 but without the internal markings (thus the direct lateral line 

 is yellow, that is, the narrow space between the lateral margins 

 of ventral and dorsal aspect). Also the propodeum bears a 

 narrow median carina and the parapsidal furrows are com- 

 plete but very narrow sutures. Club with a terminal spicule. 

 Mandibles 6-dentate. 



One female, Glenn Dale, Maryland, September 17, 1916, 

 from the woods. 



Type, Cat. No. 20605, U. S. Nat. Mus., the female on a tag, 

 the head and a hind tibia on a slide. 



Cerchysius marilandicus, new species. 



Female. — Of the stature, etc., of elasmoceri Ashmead but 

 differing as follows : The ovipositor is extruded for a some- 

 what greater length (three-fourths that of the abdomen) ; their 

 valves are slightly compressed but not broadly so ; the hind 

 legs are entirely concolorous except the first three tarsal joints 

 and the apex of the tibiae narrowly ; the middle legs are brown- 

 ish yellow except for a cinctus just below the knee and the 

 coxse; while the fore coxae and femora (except broadly distad) 

 are concolorous ; the venation is black, the marginal vein some- 

 what shorter (about twice longer than wide), somewhat shorter 

 than the postmarginal, the latter intermediate between the for- 

 mer and the stigmal (in elasmoceri the marginal is nearly as 

 long as the stigmal, somewhat longer than the postmarginal) ;
