Limbata is one of the first species to make its appearance in the 

 spring. Tiiey have been found in sunny spots on the 3rd of April. 

 Doubtless their early appearance is due to the shallowness of their l)urrovvs 

 and the warmth of the sand when exposed to the sun. 



The larv?e pass the winter in holes of about the same depth as the 

 beetles. They can, however, stand much mote cold, and remain active 

 for nearly a month later. In 1906 the last was found digging on the 26th 

 of October, at a time when the ground was frozen to an inch in depth 

 and the temperature was below freezing. A larva dug out on the 24th of 

 October dug to a depth of 4 '-2 inches in 18 hours^ with probably large 

 intervals of rest- Larv;e are often found in the middle of blow-outs, 

 though ihey prefer to dig near grass or weeds. 



Cicindela purpurea, sub-sp., liiiibalis, Ivlug. — In summer inhabits 

 damp ground. The hills of pocket-gophers ( Geomyidce) in meadows 

 are favourite haunts. It is also found in comi)any with repanda on wet 

 roadways, anil with i2-i^i/tta(a on the banks of rivers. Copulation take.'^ 

 place in May. This insect is nowhere common, and is nearly always 

 found singly or in pairs. About the middle of Sei)tember they seek out a 

 somewhat drier s|)ot than their usual summer hunting-ground in which to 

 pass the winter, and they are then found in many odd places. Edges of 

 sandy blow-outs, stubble fields, sand pits, dry roadways and clay banks 

 are aiuong the i)laces where they have been discovered. In sand the 

 depth of hole is about 16 inches, in clay it is 6 inches, and on the edge 

 of roadways where the ground was hard and rooty two specimens were 

 fouiid hibernating only 3 inches below the surface, while in sand the 

 deei)est hole was 19 inches. 



Limbalis is rather a late form to appear in the spring. The beetles 

 first emerge from [nipce in August. 



Cicindela duodecii/igutlata, Dej. — An abundant species along liver 

 banks wherever there is mud or wet sand. They differ from repanda in 

 preferring localities close to running streams, often going right to the 

 water's edge in search of food. The form collected at Aweme has much 

 the same markings as repanda, excepting that they are narrower and do 

 not extend as much at the margin, some also have the markings broken 

 more like the typical form. 



I am indebted to Prof Wickham for the determination of this species. 



The winter homes of i2guttata are usnally close to their summer 

 ones, being dug into the river banks where there are open spots, from
