but when touched, begins to fade, and after death loses all of its 
golden color. Muicrorhopala is very rare here. 
BRUCHID-. 
“Pod Weevels.” 
Some of this family do considerable damage to beans, peas, etc. 
Dr. Horn has a fine synopsis of the family in Trans. American 
Ent. Soc., 1873, vol. Iv, pp. 311-342.

“Dark ground beetles.” 
Of this large and varied family we have comparatively few 
species. Their metropolis being the semi-desert and sandy regions 
of the West. Dr. Horn published a monog. of the family in Trans. 
Amer. Philos. Soc., 1870, new series, vol. XIV, pp. 253-404, a paper 
now hard to get. Since then the same author and Dr. Le Conte 
have published synoptic tables of a number of genera in Trans. 
Amer. Ent. Soc., scattered from 1866 to 1880. Maj. T. L. Casey 
has a number of synoptic tables in the Ann. N. Y. Acad., 1890-91. 
Some of these treat of genera to which our local species belong. 
NYCTOBATES. 
N. pennsylvanicus De G. N. barbatus Knoch. 
The first occurs in great numbers under the loose bark of trees, 
the other is rare here, and differs in being smaller with much 
coarser punctures.
