This species described from one specimen, male, collected at 
Cincinnati by Mr. I)ur\-, is nearly the size, slightly larger, than 
simplex, but it differs in shape, being narrower proportionate!}', 
and its color is quite distinct from any specimens of .simplex 
that have come under my observation. It also differs in thecarina 
on the .scutellnm, the shape of the genital segment, and the 
smaller lateral lobes. 
In addition to the species treated above, I have a specimen of 
larval Aradus from Mr. Dury, which from antennal characters 
appears to be different from any American species known to me, 
and it is hoped adult individuals may be .secured so that it may 
be properly characterized. 
A SUBTERRANEAN ROOT— INFESTING FULGORID 
' Myndus radicis n. sp.) 
Herbert Osborn. 
On May loth of the present year (1903), I found a specimen 
of Fulgorid in the larval stage occurring upon the roots of several 
different kinds of plants, Impatiens, nettles and some grasses, in 
a river bed near the Olentang}' river. The insects occurred in 
galleries and cavities usually connected with open cracks and 
about to ij/2 inches below the surface, in .some cases and on 
later days, individuals were found attached to roots of plants 
above ground, but always where th.e}’ were well protected by 
drooping or dead leaves or underrubbish of the surface. Frequently 
two or three larvae were found in the same cavity, but seldom 
more than this, and the cavit}^ was lined with a cottony fibre 
.secreted from the posterior abdominal segment of the body of the 
insect. The insects were found onh’ in one small area, but dur- 
ing: the two or three weeks in which the specimens were found, 
adults and nymphs of different stages were taken in .some num- 
bers, so that it has been possible to trace a part of the life history. 
The adults were evidently all derived from larvae developed in 
the preceding weeks, and it seems quite certain that the larvae 
mu.st hatch in early May either from eggs deposited in the spring 
by hibernating adults or, what is less probable, in the preceding 
autumn. So far all efforts to find adults or nymphs during the 
autumn have failed and the status of the insect during that period 
can only be surmized. There would seem to be abundant time 
for two broods, that is, for a .second generation resulting from the 
eggs deposited in June, the individuals of which are usually 
matured by late summer, but no proof of this has been .secured. 
Actual knowledge of the life history is, therefore, confined to the 
development of nymphs during May and the occurrence of ima- 
gos during the latter part of this month and early June.
