30 IOWA STUDIES IN NATURAL HISTORY 
from Trinidad, a region between the type locally and that at 
which the present specimens were taken. 
The tip of the long abdomen of this slender insect is very 
often broken off, as are those of the greater majority of specimens 
in this lot from Antigua. This loss must have been suffered 
either before collection or at that time, as the material was eol- 
lected in spirits and remained unmounted until studied. 
Material other than the above, not submitted to the writer, 
but presumably representing the same species, must have been 
taken as indicated in the following note by Prof. Stoner: 
‘* Antigua, July, 1918. Hills and valleys, vicinity of English 
Harbor (village). A small grouse locust was taken in a low 
place near the main road, the first taken. Now and then a Man- 
tis is taken and three species of Acridiids were taken in this 
situation.’’ The mantids mentioned in this note may, however, 
refer to the specimens taken the preceding month.

Of this species there are twenty-six specimens in the collection, 
ten male and six female adults and ten nymphs of various sizes 
from Antigua, and one small nymph from Barbados without 
date. The material from Antigua was taken in June except two 
females which were taken on July 10 and 15. 
LIinearis was described and figured originally from a male 
specimen collected on Antigua. From that description and the 
accompanying little detailed figure it is difficult to make out the 
differentiating characters now in use. That they represent the 
species under consideration is fairly certain, however, since the 
present material is from the type locality, and the males agree 
very well with the original description and figure.
