Synopsis of the Family of PsELAPHID!. 
By Dr. Emi BRENDEL, of Cedar Rapids, Iowa. 
I. Antenna approximate, inserted beneath, promi- 
nent, porrected contiguous tubercles. - PSELAPHINI 
a!” eres coxe distant. 
Tarsi with two equal claws. 
6” Maxillary palpi, the last two joints similar, in 
form like the cotyledons of an acorn, without 
appendages. Antenne robust, moniliform, the 
last two joints of the max. palpi compressed fu- 
siform - - - - - CropHyLuus Le Conte 
Antennz by the last three joints clavate, the last 
two joints of max. palpi lunate, the last lorger. 
Cepius Le Conte 
6’ Antenne clavate. Max. palpi, the last three joints 
with lateral setiform appendages. 
Max. palpi, the last three joints triangular, ap- 
pendages short - - - TmeEsiPHorRus Le Conte 
Max. palpi, last three joints oval-transverse, 
appendages very long - - CreEnisTEs Reichenbach 
6" Antenne moniliform. Max. palpi minute, the 
basal joints hidden, the last two connate, together 
forming a globular club - - CHENNIUM* Latreille 
6' Antenne clavate by the last three joints. Max. 
palpi, last joint elongate with a terminal seta. 
Pytna Casey; Tyrus Aubé 
Antenne clavate by the last joint, which is enor- 
mously enlarged. Max. palpi, last joint very long 
cylindroid, rounded at top - - Cercocerus Le Conte 

* The genera At/nus Horn and Biotus Cascy do not differ more from the European 
species of Chennium than thcse species among themselves; the uncertainty in respect to the 
number of palpal joints, being in all the Pse/aphide four, does not justify a separation from 
Latreille’s genus,
