surfaces and coarsely spined. Propodeum coarsely striated 
on the entire pleural surfaces. Dorsal surface of the pro- 
podeum with a triangular area, the entire area raised and 
not bearing a central keel. Abdominal segments 2 to 5 
bordered with a fringe of coarse golden hairs. Pygidium 
finely, densely, rugose papillose on the entire apical half. 
Holotype. — Pocatello, Idaho, “73”, $ . 
This species agrees quite closely with the description of 
P. robusta Cameron, but differs in the puncturation, being 
more sparsely punctured on the pronotum and on the pleural 
surfaces of the entire thorax. There is a broad impunctate 
area in the center of the mesonotum extending back to the 
apex of the scutellum, as in P. robusta , but there is no 
impunctate lateral border. The pleural surfaces of the 
thorax are reticulated but not striated. The wing veins of 
P. robusta, are described as being entirely black while those 
of P. magna are rufous. Cameron states that the pygidium 
of P. robusta is smooth, but the writer has not seen a species 
of Paratiphia in which the female has a smooth pygidium. 
Sapyga interrupta n. sp. 
$ . Length 13 mm. Black. A line extending from the 
middle of the inner orbits of the eyes upward to and prac- 
tically filling the emarginations, a short line on the cheeks 
behind the eyes, an interrupted band on the anterior edge 
of the prothorax, a spot on the upper part of the meso- 
pleura, two small dots on the metanotum, an interrupted 
dorsal band on abdominal segments 2, 3, 4 and 5 and a 
dorsal spot on abdominal segment 6, yellow. Two small 
ventral spots on abdominal segment 2 and a ventral band 
on the following segments, interrupted on 4, yellow. Man- 
dibles black. Antennae black above, rufous beneath, except 
on the first three and last five segments. Antennas set into 
deep frontal grooves. Front elevated, bearing a distinct 
transverse ridge slightly above its junction with the clypeus, 
below which it is constricted to make the clypeus narrowly 
joined to the front. This constricted frontal area is flat
