Genus CERATOPHORUS Shuekard. 



CERATOPHORUS GRINNELLI UTAHENSIS, new subspecies. 



Very like grinnelli Rohwer, but differs in the female sex as follows : 



C. grinnelli grinnelli. 



1. Apical part of enclosure of propo- 

 deum shining impunctate. 



2. Fovea on posterior face of the propo- 

 deum punctiform. 



3. Second recurrent vein basad of the 

 second transverse cubitus by one-fourth 

 its length. 



C. grinnelli utahensis. 



1. Same dull finely longitudinally 

 striate. 



2. Fovea on posterior face of the propo- 

 deum narrow, elongate. 



3. Second recurrent vein very nearly 

 interstitial with the second transverse 

 cubitus. 



Beaver Valley, Utah. 



Type. — In the Museum of the Brooklyn Institute, New York. 



Family CRABRONIM}. 



Genus LINDENIUS Lepeletier. 



ENOPLOLINDENIUS, new subgenus. 



General habitus as Lindenius; clypeus quadra-dentate; mandibles 

 simple; basal joints of antennae emarginate; facial fovea deep, sharply 

 denned; supraorbital fovea elongate, well defined; ocelli in almost an 

 equilateral triangle; posterior orbit and sides of occiput with strong 

 carinas ; head and thorax with close fine punctures ; pronotum crested, 

 long for group, lower than dorsulum, no smooth enclosed area on 

 metanotum; venation as Lindenius; four posterior legs normal; 

 anterior femora enlarged and flattened; anterior tarsi strongly flat- 

 tened and somewhat distorted ; abdomen shining impunctate. 



Type. — Lindenius (Enoplolindenius) clypeatus Rohwer. 



This may prove to be a distinct genus when the female is dis- 

 covered. It is very distinct from Lindenius by the characters given 

 above. 



LINDENIUS (ENOPLOLINDENIUS) CLYPEATUS, new species. 



Hale. — Length about 4 mm. The notch between the lateral and 

 middle teeth of clypeus deeper than the notch between the middle 

 teeth ; a carina in the depression from anterior ocellus to facial fovea ; 

 the area between the eye and postocellar carina subfoveolate ; prono- 

 tum before the carina foveolate; scutellum with indistinct striations 

 with the punctures ; suture between postscutellum and dorsal aspect 

 of propodeum foveolate; propodeum laterally separated from pos- 

 terior face by a distinct line-like carina; depression of posterior face 

 heart-shaped ; propodeum dorsally with a median fovea which meets 

 the fovea on posterior face. Black ; mandibles, tubercles, small spots
