ENTOMOLOGICAL NEWS. [Dec., '15 



immature specimen of a Tettigoniid genus, which we believe 

 has not yet been recorded from this region but which we can 

 not determine from the material at hand. 



Amblycorypha floridana floridana Rehn and Hebard. Virginia 

 Key, III, 11, 1915, (H.; beaten from luxuriant vegetation), 

 1 very small juv. Cape Florida, Key Biscayne, III, 12, 1915, 

 (H.; luxuriant vegetation in clearing), 2 juv. 9. 



The Cape Florida specimens have been bred ; the larger 

 when taken, reached maturity March 2.2. ; the other, which was 

 very small when taken, became adult May 13. 



Amblycorypha uhleri Stal. Southside, Miami, III, 6, 1915, (H.; un- 

 dergrowth of pine woods), 1 juv. $ . 



Microcentrum rhombifolium (Saussure). Miami, III, 4, 1915, (H.; 

 on shrubbery, stridulating at night), 2 $. 



This insect was not uncommon about the town in the trees 

 and shrubbery, as could be determined on warm evenings by 

 the frequently heard stridulations. On nights when the tem- 

 perature fell at dusk below 65 (normally an infrequent con- 

 dition at Miami, but the usual occurrence at the time the col- 

 lections here studied were made) all Orthopteran stridulations 

 ceased. 



Microcentrum rostratum Rehn and Hebard. Southside, Miami, III, 

 6, 1915, (H.; undergrowth in pine woods near hammock 

 where occasional low green bushes were to be found), 1 ?, 



4. 



Belocephalus sabalis Davis. Miami, VII, 11 and VIII, 19, 1904, 

 (W. S. Dickinson), 2 juv. $. [Hebard On.]. 13 Southside, 

 Miami, III, 6, 1915, (H.; undergrowth in pine woods), 2 very 

 small juv. $ 



One of the specimens from Southside has been kept alive 

 and is flourishing on a diet principally composed of lettuce. 

 Its actions show how absolutely nocturnal the species is ; this 



13 Two females recorded from Miami and Chokoloskee, as sub- 

 apt ems (the only species of the genus at that time described) by Rehn 

 and Hebard, Proc. Acad. Nat. Sci. Phila., 1905, p. 44. (1905.) can at 

 the present moment not be found. There is little doubt that these 

 records are erroneous, as that species is not known and is probably 

 not present in extreme southern Florida. The specimens probably 

 represent this, the most generally distributed species in this region. 

 The female from Miami was from the same collection as the immature 

 females here recorded.
