A NEW GENUS OF CHALCIDOID FIYMENOPTERA 
(CALLXMOMXDiE) 
Bt T. D. A. Cockerell, 
University of Colorado. 
Mr. Charles H. Hicks has for many months been studying 
the insects breeding in dead herbaceous stems. He finds that 
these will emerge in great numbers during the winter, in the 
warmth of the laboratory, and as a result he has obtained a 
a wonderful series of bees and other insects, some new, others 
permitting the association of sexes, and many connecting para- 
sites with hosts. On Feb. 3, 1926, he bred the insect described 
below from a stem collected at Boulder, Colorado. It has since 
been determined to be parasitic on a bee of the genus Stelis.

cancellate, transversely striatulate above the antennse; ocelli 
large, in a triangle, lateral ocelli about as far from eyes as dia- 
meter of an ocellus; cheeks flattened, not at all bulging behind
