A NEW TIGER-BEETLE FROM TEXAS. 
By Wm: T. Davis, New Brighton, Staten Island, N. Y. 
In the summer of 1917 I received a tiger-beetle from Tascosa, 
Oldham Co., Texas, collected by Miss Mildred McGill, that was 
new to my collection. It also proved to be new to Mr. Charles 
W. Leng and to Mr. Edward D. Harris. Mr. Harris compared 
the insect with specimens in his extensive collection and con- 
cluded that it belonged near Cicindela roseiventris Chevrolat from 
Mexico, but was not that species, nor was it like his series of 
the subspecies mexicana Klug. Cuicindela belti Bates from Costa 
Rica is a synonym of mexicana, according to Dr. Walther Horn. 
Another subspecies of mexicana is linearis W. Horn, also from 
Costa Rica. In the description of this insect it is stated that the 
margins of the female elytra are much dilated at middle; mark- 
ings composed of exceedingly fine lines, but not reduced. In the 
three males and three females from Tascosa, the latter have the 
elytra slightly dilated at the middle, and the markings, while fine 
are reduced, as will be seen by the accompanying illustration of 
the type. A more detailed description of this insect is as follows:
