SUMMARY OF FEEDING HABITS OF AMBLYCHILA CYLINDRIFORMIS. 



They came to surface to feed at dusk. 



They are general insect feeders but they reject distasteful insects. 



They may sometimes be overcome by the prey they have captured 

 and sometimes fail to retain prey once caught. 



In summer of 1911 the larval forms were found widely distributed 

 in southwestern Kansas but the adults were scarce as ever. 



FAM. HETEROCERIDAE, 

 Heterocerus sp. 



Along the shores of the Sappa Creek, in Rawlins Co., we took 

 some beetles of this genus which live in peculiar little urn- 

 shaped mud cases. These cases were set in the mud with the 

 necks just showing above the level. A side and top view are 

 shown in PI. II, Fig. 15.
