AMERICAN HYMENOPTERA. 229 



tarsal spines are black, except those near the apex of the latter; the claws have 

 a short, erect spine near the base. 



Hab. — Quito to Guillabaniba, 9000 feet. 



Hypoferreola macliaeliieiisis sp. nov. 



Black, witli a distinct purple bloom ; wings fuscous-violaceous, the nervures 

 aud stigma black ; the 3rd cubital cellule at the top not more than half the length 

 of the 2nd; the 3rd transverse cubital uervure broadly, roundly curved. 9- 

 Length 8 mm. 



Eyes not converging much above ; they are separated there by fully the length 

 of the 1st and 2nd joints united ; the hinder ocelli are separated from the eyes 

 by a slightly greater distance than they are from each other. The mandibles are 

 broadly dark rufous behind the teeth. Wings uniformly fuscous-violaceous; the 

 Lst and 2nd transverse cubital nervures are oblique; the 1st has an oblique slope 

 on the top ; the 2nd is slightly, roundly curved on the top; the 3rd is broadly 

 roundly curved ; its upper half has a more oblique, straight slope than the lower. 

 The spines on the tibiae and tarsi are black; the hinder tarsi have a brownish 

 tinge. The temples are well developed ; the apical abscissa of the radius is 

 straight and oblique; the second recurrent uervure is received shortly beyond 

 the middle; the transverse basal nervure is almost interstitial; the accessory 

 nervure in the hind wings is received shortly behind the transverse median. 



Hab — Machachi, 9-10,000 feet. 



In Ashmead's arrangement (Canad. Ent., 1902, 79) this species 

 comes nearest to Hypoferreola. The prothorax is almost as long as 

 the mesothorax ; the subapical tooth of the mandibles is indistinct, 

 the apical large and bluntly rounded ; the apex of the clypeus is 

 transverse, with the sides broadly rounded ; the labrum has a slight 

 but distinct incision in the middle. The tarsi are closely, the tibiae 

 more sparsely spinose; the claws have a small, erect tooth ; the 2nd 

 joint of the fore tarsi is fully half the length of the first. The pro 

 notum is not " broad," but not "as long as the mesonotum " as in 

 Hi/poferreola, it being more as in Epizuron and Pcecilopompilus, the 

 other genera in Ashmead's arrangement, with which it can be com- 

 pared ; but these are different in other respects. 



Hypoferreola ambalflensis sp. nov. 



Black ; when fresh, probably with a violaceous bloom ; the wings fuscous, with 

 a faint violaceous tint; the nervures and stigma black ; the 2nd cubital cellule 

 at the top twice the length of the 3rd, at bottom shorter than it; the pronotum, 

 front and vertex thickly covered with long black hair. % . Length 8 mm. 



Antennae not much longer than the abdomen, stout, bare, except the underside 

 of the scape which is covered with black hair. Head opaque, rather thickly 

 covered with longish black hair; the upper half of the eyes curved inwardly, 

 slightly converging above; the hinder ocelli are separated from each other by a 

 slightly less distance than they are from the eyes. Wings uniformly fuscous-
