DESCRIPTIONS OF SOME NEW EXOTIC SPECIES 
OF STAG BEETLES (COLEOPTERA: LUCANIDyE) 1 
By Bernard Benesh 
North Chicago, Illinois 
The present paper, covering seven forms new to science, is 
primarily based on material conserved in our principal collec- 
tions at institutions indicated hereafter. The writer’s best 
thanks are due to Drs. Nathan Banks, R. E. Blackwelder, 
E. A. Chapin, E. T. Cresson, Jr., C. H. Curran, P. J. Darling- 
ton, Jr., F. E. Lutz, and J. A. G. Rehn for the opportunity of 
examining the Lucanidae under their charge, and the privilege 
of describing the new forms discovered, as well for the many 
examples, so generously presented, for incorporation in the 
writer’s collection. 
Many valuable data were gained from the vast number of 
specimens examined and some obvious synonymies noted, which, 
however, are reserved for a future paper. 
The new forms may be diagnosed as follows: 
Calcodes (Neolucanus) maculosus (Didier) $ 
Didier, Etudes sur les Coleopteres Lucanides du Globe, 
fasc. 7, p. 143, 9 , fig., 1930. 
In habitus allied to N. laticollis (Thun.), a species endemic 
to Java. 
$ Head transverse, black, gradually diffused toward the base 
into chocolate-brown, opaque; mentum broad, nearly straight 
in front, anterior angles broadly rounded, sides elevated, base 
nearly straight, declivous in front, remotely punctured with 
fairly large, shallow punctures. Mandibles porrect, bent up- 
ward from basal half, inner edge dentate with a series of five 
teeth, which number may vary in larger examples. Prothorax 
broader than long, dark mahogany-brown, disc shining, mar-
