Society Meetings. 



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

 John B. Angelmann, of Newark, N. J., was elected a member of lae Society. 



Messrs. Graef and Hiilst were aijpointed a Committee to see the proper authori- 

 ties to ascertain if the Society could obtain tlie 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 j^resented insects was held and 

 with only a pait ot these sold the sum of S47.49 was realized. 



Ent. Soc. Washington. Nov. 3, 1887. Mr. Schwarz read a paper on the 

 Insects living on Uniola panicitlala, as observed by him at Cape P'lorida and near 

 Lake Worth in Southern Florida. The Insects are on Oxacis and Hymenorus densiis 

 feeding on the ears of the plant ; a Phhrothrips living between the blades ; the com- 

 mon chinch bug, which occurs in this Southern latitude only in the brachypterous 

 form, and develops some peculiar habits ; Collops nigriceps, which, in the imago 

 state frequently feeds on the pollen ; RIordellistcna spldndats which develops within 

 the ?tems of the grass, and finally a Heiniptychu^ which in the larva state lives in the 

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

 \n>iovy oi Mordt'liisU-na spleitdens was exhibited and explained. Mr. Schwarz also 

 spoke on the periodical abundance of mosc|uitoes 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 \\\c one hand, and of 

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

 a peciiliar 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 Ciciudcla Belfragei which shows a peculiar 

 abnormity in the shape of an acute tubercL- on the left side of the prothorax. Mr. 

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

 Arctiida:, He finds that some genera, as Ecpantheria and Leucarctia have the claws 

 cleft to the base. Others, as Phragmatobia znd FirrJiarctia have them dentate at 

 the tip, while in Spilosoma and Anlarctia there is a distinct long tooth at the middle 

 of 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 series 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, 8 and 9. 



Dec. 8, 1887. Dr. Marx read a paper on the Morphology of the Scorpionidie, 

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

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

 specimens. He showed specimens of the insects referred to by Mr. Smith in his paper 

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

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

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

 e.-vhibit a rather remarkable resemblance in general appearance. The galleries made 

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

 Mr. Schwarz pointed out that these galleries closely resemble those of P. qturciperda, 

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

 beetle, and the larva probably do not make any galleries o( their own. Mr. Schwarz 

 also exhibited specimens of Otidocephahis Poeyi, Chevr., from Southern Florida, and
