This scries, which constitutes the first record for the genus 



from the United States, has recently been recorded and full> 



commented upon by the present author.** 



The immature individttab represent three instars; the instar pre- 

 ceding maturity by a 9 (length of body averaging approximately 4-8 

 nun.), the previous instar by a i, 2 9 (length of body averaging 

 approximately 3.7 mnu nnle tcgmina large and rounded, wings minute) 

 and the second from the last instar by a 8,2 9 (length of body aver- 

 affkw approximately 34 mm., male tegmina and wings very small and

 These specimens are brach> ptcrous ami unusually small for 

 the species. Though very dark in general coloration with 

 limbs much mottled, the female is further unusual in having 

 the exposed portion of the dorsal surface of the abdomen 

 bearing four rows of distinct pale yellowish spots, which mark- 

 ing is the normal condition in the otherwise very distinct N. 

 coroUnus and its races.
