the darkness of such by their setae, and to maintain fierce combat with the 

 owner of the burrow by means of powerful mandibles, as when bulldog meets 

 woodchuck. He also pointed out the concealment of sensitive parts like 

 antennas, and the concurrence of seasonal appearance with that of the prey. 

 The second group becomes flattened in form and has the same protection for 

 eyes and antennae. The larvae are provided with a terminal hook which can 

 be erected in a threatening manner like the tail of Staphylinidae, but is equally 

 harmless and possibly useful in retrograde movements. Ants are sometimes 

 dangerous to such larva: and their extreme flatness, enabling them to enter 

 minute crevices, aids them in escaping such enemies as well as in finding food. 

 Mr. Dow expressed his sympathy with the labor undergone by such insects and 

 Cleridae in finding their food, which is mainly scolytid larvae, for he pointed 

 out the woody tissue passing through such larvae blocks the tunnel more or 

 less making a long hard job for the Temnochilid larva to earn his dinner. 

 He also referred to the similarity in size, not more than 5 per cent, difference 

 in waist measurement being observed. Eventually also the supply of scolytid 

 larvae is exhausted and the Temnochilid adults must " treck or starve, that's 

 what make 'em leave home " in Mr. Dow's opinion. The third group consists 

 of forms which apparently subsist on fungus. These mimic certain Tene- 

 brionidae and have similar distribution. Mr. Dow gave details of his investi- 

 gation of the tunnels made by Diaperis hydni and Thymalus fulgidus larvae, 

 and stated that the tunnels made by the two insects never met, so that there 

 was no possibility of the latter devouring the former. 



His remarks were discussed by Messrs. Comstock and Schaeffer. 



Mr. Comstock exhibited Thecla ivittfeldi and mentioned each specimen 

 known to him, and the Floridian locality from which it came. His paper will 

 be printed elsewhere in full. 



Mr. Davis in reply to a question said the three specimens caught by him 

 were taken in upland oak lands, comparatively dry places, but near Lake 

 Hollingsworth and Lake Parker, at Lakeland, Fla., May 6. 



He also pointed out that another specimen was in Mrs. Slosson's collec- 

 tion raised from a full-grown caterpillar. 



Mr. Grossbeck said he was not confident that all the specimens enumerated 

 were identical with the type, there being a marked difference in size as well 

 as in the bands of color. It was true that the color character was known to 

 vary in all allied species, T. calaiiiiis. but not the size as well. 



Mr. Davis recorded the occurrence of Anthonomiis scutellaris on Staten 

 Island May 7 and 25, on beach plum. 



Mr. Schaeffer said it had been found on Long Island and at Lakchurst, 

 but that the food plant had not been previously recorded.* 



Mr. Davis exhibited two boxes of Catocala caught in Florida embracing 

 the species ilia and micronyiupha found at LaBelle and aiiiica and coccinata 



* During the reading of these minutes it was stated that this species had 

 been found on flowers and on scrub oak, probably accidental occurrences, its 

 actual food plant being beach plum.
