species in this family bore into wood, or they may occupy old burrows 
of some carpenter bee. (Howard) 
Anthophora (Clisodon) terminalis Cress, is the only species on 
record in the state, taken on aster at Itasca Park in August. 
HYLAEIDAE 
Females and most males without a flat triangular area on apical dorsal abdominal 
segment; second recurrent vein bent or directed outward before joining first portion 
of subdiscoidal vein; tongue flat, bilobed; depressions or fovae on face; wings with 
two closed submarginal cells; black and yellow markings. 
These are the bees that Ashmead called the “obtuse-tongued car- 
penter bees.” But few of them are parasitic. They burrow in the 
pithy twigs of shrubs, frequently elder, where they construct their cells, 
filling them with pollen and honey. Hylaeus sp. occurs in the state, 
taken on aster in St. Louis Co. in August. 
COELETRIDAE 
Same as Hylacidae, but wings with three closed submarginal cells; black with- 
out yellow markings; head and thorax more or less clothed with a dense pubescence ; 
tongue flattened and broad. Hind femora, tibia and tarsi of females always with a 
pollen brush or flocculus. 
Moderate sized blunt tongued hairy bees, burrowing in sandy 
places.

The females resemble somewhat the workers of the honey bee, 
but the males are much smaller. Their burrows are lined with a deli- 
cate parchment-like membrane, and are divided into several cells, six 
or more, by parchment-like partitions. An egg is deposited in each 
cell on or in a mixture of pollen and honey.
