198 PROCEEDINGS OF THE NATIONAL MUSEUM. vol.58. 



From two females, Hillmead, Prince Georges County, Mar3dand, 

 woods. 



Type.— Cht No. 20834, U. S. N.M. The females on a tag, a head 

 on a slide. 



SYMPIESOMORPHELLEUS MEDIOLINEATUS, new species. 



Female. — Similar to nigriprotJiorax Girault but of the pro thorax 

 only the meson very broadly dorsad and the upper edge of the 

 cephalic face is black, there is a black area at meson of cephalic miirgin 

 of scutum, longer than wide, irregular one on the axilla from a little 

 laterad of the middle of its cephalic margin, the dorsal thorax laterad 

 of the postscutellum is black; the propodeum is black except rather 

 broadly along the meson (more broadly distad), leaving the median 

 carina entirely free of black; and the abdominal markings are more 

 distinct. Thus very similar to californicus but aside from the entirely 

 black prothorax in that species, here the distal fourth of the abdomen 

 above is black (there is a narrow cross-stripe just preceding this black, 

 too, but in californicus this stripe is absent, the median stripe not 

 quite reaching the apex), the median stripe of the abdomen is com- 

 plete and more robust, the head (except the granulate clypeus) is 

 glabrous (not scaly) as is also the entire dorsal thorax. Otherwise 

 very much like californicus. Mandibles 8-dentate. Scape more or 

 less pale at extreme base. 



From the woods, one female, Glenndale, Maryland, October 6, 1916, 

 Type.— Cat. No. 20640, U.S. N.M. , the female on a tag, the hind 

 tibiae and the head on a slide. 



CHRYSONOTOMYIA AURIPUNCTATUS Ashmead. 



Genotype. 



The head is missing but the body is like the Australian AcJiryso- 

 chaiis grandis Girault and the species is undoubtedly an Omphaiine. 

 The generic description does not apply at all. Type examined. 



HOPLOCREPIS ALBICLAVUS Ashmead. 



Genotype. 



Head (cephalic aspect) elliptical (the axis transverse), the round 

 eyes forming the poles, the head about twice wider than long (exclud- 

 ing the clypeus which projects, the antennae inserted a little below 

 the middle but much above the ventral ends of the eyes, the cheeks 

 distinct, their aspect nearly ventral; scrobes short. Ocelli in a 

 triangle. One short ring-joint, funicle 4-jointed (club not seen). 

 Parapsidal fin-rows complete, distinct, not reacliing pronotum, the 

 parapsides shortened and rather humped cephalad. Scutum with 

 a sharp median carina, abbreviated at each end. Scutellum with 

 its disk or dorsal aspect sharply margined except at base and 

 with a Y-shaped carina along the meson formed by two elbowed 

 carinae, the prong distad, no grooves, the space between the carinated 

 margins and the central carina honej^combed. Propodeum glabrous,
