June the beetle appearing in that month and continuing to issue! 
from’ the ground till fall. On the 19th of May m Union county 
amon cr a Considerable number of root-worms of other species, I 
found°a few half-grown larvie of this, easily distinguished fiom those 
of Scelodonta pubescens, with which they occurred, by their greatly 
inferior size at that time. On the 28th of June I received from 
Mr Earle specimens of this species in both lie larva and imago 
stages the latter having just emerged The adults were now abun- 
dant on the leaves of strawberries, and many also occurred on the 
foTace of the grape, adjacent to the strawberry held, associated m 
both cases, with a dark; steel-blue species ot the same genus ( Colas- 
pis tristis). . 
An assistant, Mr. Garmau, obtained adults by sweeping stubble 
fields at Du Quoin on the 4th of July, and sent from Anna, on the 
9 th specimens of larvie, pup* and adults all obtained from the 
earth P Two of the latter were from oval cells m the ground, within 
whicli they had lately transformed. He also found adults very 
common on the foliage of the strawberry at this date and reported 
imacros abundant on grape leaves on the lltli. By the lotn, all 
the Cv* and pup* had emerged, but the adults were found in 
sweeping the leaves of the strawberry where they continued common 
until P August 1st. It is especially worthy of remark that the only 
field in which Colaspis larv* were found had been se in the spring 
of that year, the ground having been previously m wheat. 
Our collections of the adults made in Northern and Southern 
Illinois represent only the months of June and July, but. m the 
course of extended and careful search of the earth in a considerable 
number of strawberry fields made in the months of September, 
October, November and December in parts of Southern Illinois now 
known to be infested by this species, not a single specimen of Colaspis 
was encountered. Among these fields was the one fiom winch t e 
larv* pup* and young imagos were sent me in June; but m which a 
long search in early September failed to discover a single specimen in 
any stage. These and other fields in the region in which the larvae 
had occurred, were also most carefully hunted over early m l Decern- 
her by digging up the earth, and raking up the mulch but not a 
single Colaspis occurred in any stage, even where strawberries were 
raised among grapes.” 
The above facts warrant us in assuming that the species is 
single-brooded, that the larv* are hatched in spring (wHetHe from 
eggs laid in autumn or from those deposited by hibernat g 
is not yet known,) that they get their growth m-June or July, and 
that the adult beetles may be found during the remainder , 
season, at first in strawberry fields and afterwards in .the_ vineyaids, 
and indeed, quite generally distributed. They are at this season,
