Society Meetings. 



Brooklyn Entomological Society. Dec. 6, 1887. Fifteen members present. 

 John B. Angelmann, of Newark, N. J., was elected ;i member oi tae Society. 



M :ssrs. Graei and Hulst were appointed a Committee to see the proper authori- 

 ties to as. e it a in it the Society could obtain the u e of rooms for meetings in the Hoag- 

 land addition to the Long Island Medical College. 



As arranged at last meeting an auction sale of presented insects was held and 

 « ith only a pait ol these sold the sum of $47.49 was realized. 



Ent. Soc. Washington. Nov. 3, 18S7. Mr. Schwarz read a paper on the 

 Insects living on Uniolu paniculala, a-- observed by him at Cape Florida and neai 

 Lake Worth in Southern Floiida. The Insects are on Oxacis and Hymenorns densus 

 on the ears of the plant ; a Phlceolhrips living between the blades ; the corn- 

 inch bug, which occurs in this Southern latitude only in the brachypterOus 

 form, and develops some peculiar habits; Col/ops nigriceps, which, in the imago 

 State frequently feeds on the pollen ; Mordellistena splendens which develops within 



ins of the grass, and finally a Hemiptychw which in the larva state lives in the 

 stems vacated by the Mordellistena. A lull series of specimens illustrating the life 

 history of Mordellistena splendens was exhibited and explained. Mr. Schwarz also 

 spoke on the periodical abundance of mosquitoes on the shores of Biscayne Bay, 

 whenever the regular trade wind ceases to blow. At such times there is a curious 

 correlation in the increase of the numbers of mosquitoes on the one hand, and ot 

 certain species of dragon flies on th.2 other. Mr. Schwarz finally called attention to 

 a peculiar habit noted by him in Danais Berenice which congregated in great numbers 

 on stones which had been heated by fire. 



Mr. Smith exhibited a specimen of Cicindela Belfragei which shows a peculiar 

 abnormity in the shape of an acute tubercle on the left side of the pro thorax. Mr. 

 Smith further called attention to some modifications of tarsal structure among the 

 Arcliides. He finds that some genera, as Ecpantheria and Leucarctia have the claws 



* the base. Others, as Phragmatobia and. Ptrrharctia have them dentate at 

 die tip. while in Spilosdma and Antarctia there is a distinct long tooth at the middle 

 oi the claw. The claws are not always alike on all feet, and where there is any 

 difference the fore tarsal claws are the ones that are modified. What systematic 

 value this structure has, is yet uncertain. There are two distinct scries indicated in this 

 family by the venation, by the position of vein 10. In one series it arises from the 

 subcostal before the end of the cell, in the other it arises from a stalk with 7, S and 9. 

 I >ec. 8, 1887. Dr. Marx read a paper on the Morphology of the Scorpionidce, 

 illustrating tin' same by a series of carefully prepared drawings ot the various structural 

 Mr. Schwarz made a series of smaller communications, with exhibitions ol 

 specimens. lie showed specimens of tin- insects referred to by Mr. Smith in his paper 

 on '-Ant- Nests and their Inhabitants" (Amer. Nat. 1886, p. 686) viz : Tapinoma 

 sessile, an unnamed Heteropterous larva, an undescribed Anlhicus and the two species 

 .1 Teinopophus, which, all occuring under the same conditions and at the same place, 

 exhibit a rather remarkable resemblance in general appearance. The galleries made 

 by Pityophthorus minutissimus under bark of Red Oak branches were exhibited, and 

 Mi. s hwarz pointed out that these galleries closely resemble those oi P. querciperda, 

 exhibited at a former meeting. The galleries all seem to be the work of the parent 

 . and the larva probably do not make any galleries ol their own. Mr. Schwar/ 

 also exhibited specimens of Otidoccphalus Poi-yi, Chevr., from Southern Florida, and
