sentello inermi. Tegule parum nitide, minutissime obsoletim 
punctulate, punctis nonnunquam tribus aut duobus majoribus 
notandis. Abdominis segmentum primum minus for titer punc- 
tatum ; secundum ad basin subfortiter convexum. Segmentum 
2 ventrale post sulecum fortissime elevatum, elevatione summa sat 
fortiter prominente; segmentum ultimum subconvexum, haud- 
quaquam depressum, breviter pilosum. Long. 9-11 mm. 
In the male the yellow of the first segment is nearly straight in 
front, in the female it is emarginate in the middle. The ‘apical 
band ah the second segment in the male does not reach the middle 
of the segment, in the female it extends far beyond the middle 
basally. “T think this is mere individual variation and probably 
not a constant sexual difference.

IT have seen only one old example in dirty condition. It is 
very distinct from any other that has similar coloration and 
markings. The clypeus is more or less flat over most of its 
surface, excepting the base and the decurved sides.

There is a single female of this species in the British Museum, 
bearing a label ce Alastor eriurgus, var.” Practically it resembles 
eriurgus in colour, but in structure it is extremely close to the 
preceding, to which it has no superficial hkeness. The tegule
