NEW PLASTOCERIDiE AND A NEW CEBRIO 
(COLEOPTERA) 
By H. C. Fall, 
Tyngsboro, Mass. 
The little family of aberrant Elaterids known as the Plas- 
toeeridae contains thus far only twenty described species from 
within our faunal limits, and these are very sparingly represented 
in the great majority of collections. The wingless females es- 
pecially are very rarely taken, and in a series of one hundred of 
more individuals in my own cabinet only three are of this sex. 
With the exception of Euthysanius blaisdelli Tanner, des- 
cribed two years ago, 1 no new species of this genus or of Aplastus 
has been made known in over half a century. Descriptions or 
five new forms in these genera, and of a new Aphricus are offered 
in the following pages. The types of all these are in my own col- 
lection. 
Euthysanius homi n. sp. 
Body above, legs and antennae pale reddish brown, meta- 
sternum and abdomen more flavate; integuments shining, 
pubescence very short, pale and suberect. 
Antennae of male flabellate as usual, the terminal joint 
perceptibly though only slightly shorter than the branch of the 
11th joint. Head densely punctate, a transverse impression 
between the eyes which is posteriorly angulate at middle; eyes 
prominent, separated on the front by a little more than twice 
their width as viewed from the front.
