Length of front wing 40 



Length of front tibia 8 



Length of hind femur 13 



The measurements of the male paratype, collected at the 

 same time and place, are almost exactly those O'f the type. 



The large size, the narrow occiput, the shining black areas 

 behind the eyes, and the clear antecubital areas of both pairs 

 O'f wings of floridensis will readily separate it from transversa. 



CICINDELA TRANQUEBARICA AND ITS HABITS. 



By W. T. Davis, Staten Island, N. Y. 



Cicindela tranquebarica was observed at Coram, Long Island, 

 on the farm of Benjamin Still, situated in the sandy district about 

 a mile north of the village, on September 19, 1920. 



About four o'clock in the afternoon I selected a particular 

 Cicindela tranquebarica on the sandy wood-road in the pines west 

 of the house and commenced to watch it. It often ran about at 

 considerable speed, would occasionally captui;e a small insect, and 

 anon would remain quiet for a considerable time. Only once did 

 it fly, at which time it changed its position about 20 feet to the 

 west. Once it ran up to my shoe as I sat on the carpet of 

 bear-berry vines by the side of the path. It started to dig a hole 

 at the side of the path, but quit after working four minutes. 

 Later it found a depression in the sand caused by the foot of a 

 horse and commenced to dig a second hole at that part of the 

 depression presenting a perpendicular face about one and one-half 

 inches high. The beetle worked fifteen minutes, making a tunnel 

 with its head in the hole and throwing out the sand with its legs. 

 Then it turned about and backed into the hole, but did not close 

 up the mouth of the tunnel ; its head and mandibles were visible 

 near the entrance. This was at 4.55 P.M. I secured a straw and 

 gently poked the beetle, which would open its mandibles and fight 

 back. I went away after teasing it a while and left it to its night's 

 repose.
