August, September, October, November and December. As is usual 

 with the species of this genus a great amoiuit of variation in size is 

 noticed in the series. 



All the specimens of this species which I took were captured among 

 the weeds of an unused field and in the grass in our yard. The males 

 stridulate continually, and their constant creeee-creee-creee may be 

 heard from every side on a warm day. This species fills the place 

 which is occupied by Nemobius fasciatus in the North. (M. H.) 



Nemobius socius Scudder. 



This sti iking form is represented b}' one male and ten female speci- 

 mens, all taken at Thomasville in Ma}', June, July and September. 

 But two of the specimens are brachypterous, the other nine possessing 

 caudate wings. 



These specimens were collected at night about the arc lights, to which 

 they were attracted by the light. (M. H.) 



Nemobius ambitiosus Scudder. 



The beautiful but subdued coloring of the male of this species makes 

 it an easily recognized form, and a series of thirty individuals of both 

 sexes have been examined. They were taken at Thomasville in Febru- 

 ary, March, April, October, November and December. In the spring 

 of 1903 several individuals were taken in Leon count}^ There is some 

 variation in the depth of color in the females, ranging from dull black- 

 ish to blackish brown and umber. 



This beautiful species is ever present, lacing astir on the coldest 

 winter days. I heard one specimen stridulating in the pine straw on a 

 morning when the mercury had just risen above freezing. The sound 

 produced by the males is quite different from that of any other species, 

 but it would be indeed difficult to describe the pitch which makes it so. 

 (M. H.) 



Nemobius cubensis Saussure. 



This species, which bears quite a superficial resemblance to N. socius, 

 is represented in the collection by five specimens, one male and four 

 females, the male individual being referred here with a little doubt. 

 All the specimens were taken in May and June, 1903, at Thomasville. 

 Nemobius exiguus Blatchley. 



It was with considerable surprise that this species was recognized 

 in the material studied, but a series of forty-seven specimens appear 

 to be perfectly referable to this species, previously known only from 

 Indiana. Thomasville individuals were taken in January, February 

 and December, and one specimen was collected at the Ocklockonee 

 river on March 29, 1904.
