 ground vegetation in the more open scrub.

 Manomera tenuescens (Scudder).

 ' On careful examination of our Florida series of twenty adults of 

 this genus, two species were found to be present, distinguishable by 

 very good characters in the male and female genitalia and also in the 

 distal abdominal segments. The original description and figure of 

 tenuescens show conclusively that the form with the elongate sub- 

 cylindrical anal segment in the male is that species. 



The two species of Manomera were taken together in the same 

 situations; on prairie, in undergrowth of pine woods, and at night on 

 the extremities of the leaves of the saw palmetto (Serenoa) at Home- 

 stead and in pine woods undergrowth on the edge of a hammock at 

 Detroit.

Closely allied to M. tenuescens (Scudder), agreeing in general form, 

 structure of the limbs, and coloration, but differing in the much more 

 abbreviate seventh, eighth, and ninth abdominal segments and the 

 form of the apex of the male abdomen. In the male the seventh, 

 eighth, and ninth dorsal abdominal segments together are hardly or 

 not at all longer than the sixth dorsal segment, while in tenuescens 

 they are half again as long; the eighth dorsal segment in brachypyga 

 is transverse instead of longitudinal; the ninth segment fornicate 

 and subinflated instead of decidedly longitudinal and cylindrical as 

 in tenuescens; while the cerci of tenuescens have a delicate spine at 

 the internal base, which is represented in brachypyga by a much 

 more robust tooth. The two forms can be very readily separated 

 when the apex of the male abdomen is viewed from either the dorsal 

 or lateral aspect. In the female the sixth dorsal abdominal segment 

 is considerably longer than the seventh and eighth segments, while 

 in tenuescens it is less than the seventh and eighth segments in 

 length; the ninth segment is equal in length to the prothorax, which
