114 Journal New York Entomological Society. [Vol. xxvil 



Mr. W. P. Van Duzee, present as a visitor, spoke of the ornamented tibia 

 and tarsus in the dipterous genus Dolichopits, where the femora are always a 

 little flatened and usually clothed with black hair ; if, however, the femora are 

 in large part yellow, the hairs also are yellow. In some species the lower 

 edge is glabrous and the lower row of hairs elongate, like a black fringe. In 

 one species there is a bristle on hind femora near tip, with the usual hairs 

 omitted in a glabrous space following. 



Mr. E. A. Chapin, also present as a visitor, spoke of the legs of fleas, 

 which he said exhibited great similarity, though the tibial bristles, sometimes 

 longer than the tarsus, the very large coxa (longer than femur), the method 

 of attachment in the high trochanter, and other peculiarities were of interest. 



Meeting of February 4. 



A regular meeting of the New York Entomological Society was held at S 

 P.M. February 4, 19 19, in the American Museum of Natural History, Presi- 

 dent L. B. Woodruff in the chair, with nineteen members and Prof. H. C. 

 Fall present as a visitor. 



Letters from Mr. Dow were read by Messrs. Leng and Davis. 



Mr. Woodruff read a paper, " Fall Notes on Alabama Butterflies," illus- 

 trated by four boxes of specimens. 



Messrs. Davis, Lutz and Shoemaker corroborated his statements in regard 

 to migration of Catopsilia eubule and recalled the communications of Mr. 

 Shannon on migration. 



Dr. Bequaert read a " Review of Rau's ' Wasp Stories Afield,' " praising 

 highly their care in obtaining correct identifications, patience in lengthened 

 observation and conciseness while with Col. Robinson at Wingina, Va., as an 

 instance of wasps going to a distance for suitable pebbles to use as pounding 

 tool. 



Dr. Lutz recalled Dr. Williston's early notice of wasp's use of tool. Dr. 

 Lutz exhibited casts of burrows of tiger beetle and wasp made by Mr. Wunder 

 under his direction and pointed out the advantages of the method. Two 

 methods were used: (1) The earth around the burrow was hardened by pour- 

 ing glue or shellac down the hole; the burrow was then dug out; (2) an exca- 

 vation was made in such a way that a cross section of the burrow was exposed 

 on one face of the excavation ; a plaster cast was then made of that face. 

 This plaster cast could be used as an accurate note concerning the burrow, 

 or, using it as a mold, it is frequently possible to get a plaster reproduction 

 of the cross section of the burrow. Of these two methods, the second is the 

 better. 



Dr. Lutz also exhibited winged ant clinging to leg of the Microbembex that 

 had captured it as an instance of the latter using live as well as dead insects. 



Mr. Watson read a paper on " The Egg of Polites cernes Boisd. & Lee," 

 illustrated by blackboard drawings. 



Mr. Davis read a paper on a remarkable nest of Vespa maculata and the 

 number of queens of Polistes that sometimes combine their efforts in nest 

 building.
