scape of which at apex and the flagellum, brown ; the joints of the latter 

 are about four times as long as thick. 



Described from two specimens, male and female. 



Eumegaspilus, n. g. 

 This genus is distinguished from Megaspilus Westwood in being en- 

 tirely wingless or then with rudimentary wings, and by the shape of the 

 flagellum, which is sub-clavate. In Megaspilus it is flagellate, i. e., tapers 

 gradually to a point at apex. 



(2) Eumegaspilus Canadensis, n. sp. 



Female. Length .09 inch. Polished black; the head and thorax 

 only showing a delicate, reticulated sculpture under a high power lens. 

 On the head are a few large punctures, particularly on the vertex, two 

 small foveae or depressions on each side of front ocellus ; occiput pro- 

 minently margined ; eyes pubescent. The antennae are n -jointed, wholly 

 brown-black; flagellum sub-clavate. the first funiclar joint longer than the 

 pedicel, the others sub-equal but gradually widened, the terminal joint 

 being the longest and thickest. Mesothorax with three grooves. Legs, 

 including coxae, of a uniform brownish-yellow. Abdomen highly polished 

 with a depression near the base. 



Described from one specimen. 



(3) Eumegaspilus Ottaweusis, n. sp. 



This species is much like that just described, but it is more slender 

 and more highly polished ; the head is impunctured, while the scape at 

 base, the pedicel, the 2nd, 3rd and 4th flagellar joints, and the legs, in- 

 cluding the coxae, are honey-yellow. The rudimentary wings are linear 

 and reach not quite to the middle of the abdomen. 



Described from one specimen, 



Megaspilidea, n. g. 

 This genus is at once distinguished from the others by having but one 

 groove on the mesothorax — the median one, the parapsidal grooves not 

 being present ; also by the difference in the flagellar joints. 



(4) Megaspilidea minuta, n. sp. 



Female. Length .04 inch. Head and thorax shining black, micro- 

 scopically, reticulately sculptured. Eyes large oval, pubescent. Antennae 

 n-jointed, scape ob-clavate, more than half the length of the flagellum ; 

 flagellum sub-clavate, first joint hardly half the length of pedicel, others
