Dr. Henri de Sassure and the Imperial Academy Leopoldino-Caroline. 

 Mr. Martindale reported the capture of butterflies and moths. A letter 

 was read from Mr. VV. J. Fox, dated Kingston, Jamaica, April isth, in 

 which he said he and his companion, Mr. C. \V. Johnson, were having 

 fair success in collecting insects on the island. They expected to go to 

 Port Antonio and remain there until May yth, when they would leave for 

 home. HENRy SKINNER,

THE ENTOMOLOGICAL SOCIETY OF WASHINGTON. December 4, 1890. 

 The corresponding secretary read a paper by Mr. P. R. Uhler entitled, 

 "Observations on some remarkable forms of Capsidae," in which were 

 described two new genera, Heidemannia and Peritropius, represented by 

 one species each, viz., H. cixiiformis and P. saldcsformis. The paper 

 also contained a note on the recent discovery by Mr. Heidemann, in the 

 District, of one of Say's long-lost species, Cylaphus tenuicornis. 



Mr. Howard read a paper on the " Parasites of the Hemerobiinae," in 

 which, after dwelling on the numerous protective characters of this sub- 

 family of neuropterous insects, he spoke of the known hymenopterous 

 parasites, and added the encyrtid genus Isodromns as the only known 

 primary parasite in the country with the single exception of the egg para- 

 site mentioned by him on page 10, Vol. I, of the society's proceedings. 

 Several secondary parasites were mentioned, and a list of the European 

 parasites and hyper-parasites was given. 



Mr. Marlatt presented a note in which he proposed the specific name 

 unicolor for a species of Monoctenus, the larva of which feeds on the Red 

 Cedar. This Saw-fly had been described by him as M. juniperi (see 

 Trans. Kans. Acad. of Sciences, Vol. X, p. 82), which name was preoc- 

 cupied by an European species of the genus. 



Mr. Banks read a paper on Thalmia parietalis Hentz, a spider which 

 he had taken in Texas, and which had been lost since Hentz's time. In 

 studying this species in connection with the Pholcidae, Scytodidae, Fili- 

 statidae, Urocteridae, Euyoidse and Hersilidae, he reached the conclusion 

 that these spiders are closely related, and ought to be included in one 

 group of family importance for which he proposes Duges' name Microg- 

 nathes changed to Micrognathidae. 



Mr. Townsend read some notes on Tachinicke sens, /at., synonymical 

 and critical, with, particular reference to the confusion of the sexes by 

 early describers. A good number of species were noticed and several 

 new ones were described. 



Prof. Riley read and commented on letters from Mr. Wm. H. Ashmead, 

 now studying in Berlin, and Mr. S. S. Ratlmm, of Lancaster, Pa. He 

 then read a note on an exotic roach {Ponchlora z'iridisf] which he had 

 recently received from Dr. C. F. Gissler, of Brooklyn, N. V. The re- 

 markable feature was that the roach was certainly viviparous, a habit 

 believed not to have been hitherto recorded of any species of the family 

 Blattidai. Figures of the parent roach, and of its young greatly enlarged,
