oth and shining; the prothorax with a distinct lateral margin, 
tibiae are sulcate, the antennae thickened toward the end, and 
middle and hind tibiae toothed toward the tip. 
aria aterrima is oblong, short, varying from yellowish red to 
k, the legs being, however, always pale. In the lighter speci- 
s, the ventral segments and three spots on each elytron are black, 
head (Plate VIII, Fig. 2) is coarsely punctate, the sides of the 
ax are slightly rounded, and rather sparsely punctate. The 
ra are deeply punctate-striate, with smooth intervals, the striae 
g obsolete before the apex. 
aria sexnotata is said to be distinguished by the much more 
state head, and by the less punctate, minutely alutaceous thorax. 
DISTRIBUTION. 
lese forms occur throughout the whole country, from the Atlantic 
m to California, and from Massachusetts and Michigan to the 
/hern States. They are abundant on the juniper (Jiiniperus 
minis), and on the wild crab apple (Pyrns coronaria ) as well as. 
i he strawberry; and occur less commonly on a considerable 
3ty of plants, both tame and wild. 
LIFE HISTORY. 
have already said that the early stages of this insect (the larvae 
daily) are almost indistinguishable from those of another species 
genus, occurring in the ground with it, and attacking the straw- 
y plant in precisely the same manner. When we take into 
unt the further fact that this second root-worm belongs to a 
ies whose early stages and life history have hitherto remained 
lown, we see how inevitable it was that these two larvae should 
) been confounded, and that some errors should have resulted 
i this confusion when the attempt was first made to clear up 
* life history. 
7 the repeated breeding of larvae taken at various times and 
es during the last year, and by numerous collections and field 
rvations of these insects in all their stages, we are now placed 
i position to elucidate the life histories of both Paria and 
odonta. 
ist April the adult beetles were found not uncommonly in straw- 
Y fields at Centralia, Cobden and Villa liidge, having evidently 
y emerged from their winter quarters; but the most careful 
i 3h of the fields infested by root-worms yielded no Paria larvae, 
>eing Scelodonta at that time. 
i the 18th of May, the adults were again obtained in consider- 
numbers by sweeping the foliage of strawberries at Villa Eidge; 
on the 15th of June, a few were seen in the ground, about the 
i of the strawberries, by Mr. C. W. Butler, of Anna, probably 
ged in oviposition. 
f the 20th of July, Mr. Garman found larvae and pupae of this 
ies among the strawberry roots at Cobden, and adults on the 
ge; and on the 26th all stages were sent me from Lansing,
