This species was reared from larvee which were attacking wheat in the 
Big Bend Country of Washington. It falls in Horn’s group IV and in 
Cande/e s section VI. According to tlie latter author it falls next to 
Corynibites conjungens Lee., from which it can be easily distinguished 
by the confluent punctuation on the sides of the pronotum and by being 
entirely black except for a very slight brownish tinge on the legs.
