NORTH AMERICAN HYMENOPTERA. 241 



Sphseroplithalina aIbo|>ilo»«a Blake. 



Femnle. — Ferruginous; head subquadrate, posterior angles rounded, closely and 

 finely punctured; eyes small, round; antennie fusco-ferruginous ; mandibles 

 tipped with black ; thorax subquadrate, narrowed behind, densely punctured, 

 metathorax abruptly truncate ; legs castaneous, clothed with glittering white 

 hairs ; abdomen ovate, second segment densely and finely punctured, apical seg- 

 ments blackish, fringed with whitish pubescence ; under side paler than above ; 

 entire insect clothed with erect white hairs. Length 8.5 mm. 



Hab. — Texas. (Belfrage) One specimen. 



This species closely resembles some individuals of ferrugaia, but 

 may be readily distinguished by the rather dense, white, erect pubes- 

 cence. 



Sphferophthalma caneo Blake. 



Female. — Ferruginous ; head round, not as wide as thorax, clothed with cine- 

 reous pubescence; eyes large, round, prominent; scape of antennae with whitish 

 hairs; thorax ovate, narrowed posteriorly, thinly covered with griseous hairs, 

 metathorax obliquely truncate ; legs thinly clothed with glittering whitish 

 hairs ; abdomen ovate, finely punctured, thinly covered with erect white hairs : 

 apical margin of second segment fuscous at middle, fi-inges of segments white. 

 Length 8 mm.

Allied to J'erru(/at(( Fal). 



Sphierophtlialnia niutata Blake. 



Female. — Ferruginous ; head rounded, transverse, finely and densely punctured, 

 mandibles blackish at tip ; antennae uigro-fuscous ; eyes small, round, convex ;

 remaining segments fusco-ferruginous, the apical margins fringed with pale yel- 

 lowish or white pubescence. Length 8.5-13 mm. 



Hab. — Atlantic and Southern States. 



Upon the examination of a large series of specimens this may 

 prove to be only a variety of ferrugata. It is, distinguished by the 

 more or less distinct pale spots on the second abdominal segment ; 

 thorax is rather shorter and broader, and the color of the apical 

 fringe of the segments varies precisely as in jerrugata. 



Sphierophthalma scsevola Blake. 



Female. — Ferruginous ; head subquadrate, posterior angles rounded, slightly 

 wider than the thorax, finely punctured, thinly clothed with appressed reddish 

 golden pubescence; antennae fuscous, mandibles blackish at tips; eyes round, 

 prominent; thorax ovate, much narrowed posteriorly, closely punctured ; sides 

 of metathorax smooth ; legs blackish, thinly clothed with pale glittering hairs,
