Of the ten speci- mens at hand, nine were found in ants' nests be- neath logs or flat stones, all singly but two. Al- though taken in six different years, they were all collected between the two dates above mentioned. On this and most other species there are pubes- cent depressed spa<'(',s near the front angles and beneath or near tlie hind ones which are sup- posed to be glandular and to excrete a liquid very palatable and attractive to the .ants, with which they are found in company. LeConte records* several in- stances in which specimens have had the projecting portions of the hind angles fall off on account of the continual gnawing or sucking of the ants at the glands. (Fig. 417.) The beeth-s are sluggish in- sects which feign death when touched, and seem to be held in cap- tivity by the ants, which pull them back into the vicinity of the nests whenevei- they attempt to escape
