42 The Ohio Naturalist. [Vol. IV, No. 2, 



This species described from one specimen, male, collected at 

 Cincinnati by Mr. Dury, is nearly the size, slightly larger, than 

 simplex, but it differs in shape, being narrower proportionately, 

 and its color is quite distinct from any specimens of simplex 

 that have come under my observation. It also differs in the carina 

 on the scutellum, 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 



CMyndus 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 ojDen cracks and 

 about Yj to I ^ inches below the surface, in some cases and on 

 later days, individuals were found attached to roots of plants 

 above ground, but always where they were well protected by 

 drooping or dead leaves or underrubbish of the surface. Frequently 

 two or three larvae were found in the same cavit}-, but seldom 

 more than this, and the cavity was lined with a cottony fibre 

 secreted from the posterior abdominal segment of the body of the 

 insect. The insects were found onl}' 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 

 must 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 

 €ggs deposited in June, the individuals of which are usually 

 matured b}^ 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- 

 ^os during the latter part of this month and early June.
