The immature individuals represent three instars ; the instar pre- 

 ceding maturity by 2 9 (length of body averaging approximately 4.8 

 mm.), the previous instar by 2 $,2 9 (length of body averaging 

 approximately 3.7 mm., male tegmina large and rounded, wings minute) 

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

 aging approximately 3.4 mm., male tegmina and wings very small and 

 equally projecting). 



Nemobius ambitiosus Scudder. North edge of Brickell's Ham-

 cayne, III, 12, 1915, (H.; bare muck in red mangrove

These specimens are brachypterous and 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. 

 carolinus and its races.

 in red mangrove swamp, on barr muck under mots), 1 ,
