towards the vertex, where they are separated by a distance equal 

 to the length of the second and third joints of the flagellum 

 combined. Antennae very stout, a little longer than the thorax 

 and median segment combined, tapering to the apex, the joints 

 arcuate beneath ; scape very short, little more than half as long as 

 the second joint of the flagellum, which is equal in length to the 

 third. Pronotum short, depressed, rounded anteriorly, the 

 posterior margin feebly arched. Median segment convex, as long 

 as broad, longer than the mesonotum, very gradually sloped 

 posteriorly. Abdomen subpetiolate, elongate fusiform ; second 

 ventral segment without a transverse sulcus. Tarsal ungues 

 bifid ; legs slender, a few minute spines on the posterior tibia?. 

 Second abscissa of the radius twice as long as the third, the second 

 cubital cell a little longer than the third on the cubital nervure ; 

 first recurrent nervure received at two- thirds from the base of the 

 second cubital cell, second at the middle of the third cubital cell ; 

 submedian cell slightly longer than the median ; cubitus of the 

 hind wing originating before the transverse median nervure. 

 Opaque, pruinose. 



Black ; the antennas (except the three apical joints) bright 

 orange ; labrum, sides and base of the clypeus, scape beneath, 

 and the face as high as the base of the antennas continued 

 for a short distance on the inner margins of the eyes, creamy 

 yellow; posterior margin of the pronotum, a transverse band 

 on each side at the base of the second dorsal abdominal seg- 

 ment, another shorter and narrower on each side near the 

 base of the third segment, the spines of the tibia?, and a line near 

 the base of the posterior tibia?, white ; anterior tarsi and tibia? 

 testaceous brown. Bands of greyish pile at the apex of the 

 abdominal segments, very narrow on the first three, a little 

 broader on the others. Thorax and median segment with patches 

 of silvery pile. Wings hyaline, margined with pale fuscous, a 

 pale fuscous band from the radial cell crossing the third cubital 

 cell. 



Length 11 mm.

1 place this species in the subgenus Episyron with some doixbt, 

 as it is very difficult to separate the males of that group from those 

 of Calopompilus. 



Anoplius (Episyron) lepidohirtus, sp. n. 



2 . Clypeus very slightly convex, nearly three times as broad 

 as long, the apical margin transverse. Eyes very narrowly 

 separated from the base of the mandibles, slightly convergent 

 towards the vertex, where they are separated by a distance about 

 equal to the length of the second joint of the flagellum ; posterior 

 ocelli a little further from each other than from the eyes. 

 Antenna? about as long as the head, thorax, and median segment 

 combined ; the second joint of the flagellum nearly twice as long as 

 the third. A very delicate frontal sulcus, not reaching the
