An African Pterothysanid (Lepidoptera) : In Hampson's recent 

 revision of certain small families the Pterothysanidie stand repre- 

 sented by a single Oriental genus, of very few species. Lately the 

 Madagascar Caloschemia monUifera has come to hand, and proves to 

 be a second Pterothysanid, very close to Pterothysanus, perhaps not 

 generically distinct. The venation is the same and in both the frenu- 

 lum is rudimentary (not absent as generally stated). The tympanum 

 is absent, the metathorax being well chitinized and simple in type, 

 practically like the mesothorax at first glance. This shows there is no 

 connection with the Liparidae or HypsidcX, where the genus Caloschemia 

 now stands. The free R., (vein 7) is also practically unique. Both 

 have the angulate Sc and brace-vein of the hind wing characteristic of 

 the Geometridse and Callidulidae, whicli are probably the closest rela- 

 tives. The two genera may be distinguished as follows : 



Pterothysanus: Palpi drooping, hairy below, fringe on inner margin 

 of hind wing extremely long. 



Caloschemia: Palpi porrect, smooth-scaled and rather longer, inner 

 margin with fringe more moderately lengthened. 



The family will be another of those interesting links between the 

 Malagasy and Oriental regions, like Enploca and Papilio antcnor. —

Notes on Katydids. — In this Journal for March, 1920, it is stated 

 that the one-time very abundant katydid, Pterophylla camcllifolia 

 (Fabricius) was becoming extinct within the limits of New York 

 City. For several years search had been made on Staten Island, where 

 it was once very common, but none had been found. During the 

 summer of 1921 Miss Miriam Campbell discovered a small colony of 

 this species in the mixed growth of pines, oaks, etc., extending along 

 the northerly boundary of the Moravian Cemetery. Search was con- 

 tinued in other parts of the Island, but no additional Pterophylla were 

 located. Mr. S. Harmsted Chubb, of the American Museum of Nat- 

 ural History, heard four or five katydids in 1921 near 250th Street, 

 between Van Cortlandt Park and the Hudson River. 



It is also worth while to record that the oblong-winged katydid, 

 Amhlycorypha ohlongifolia (De Geer), was very scarce on Staten 

 Island during 1921, while it was exceedingly abundant there in 1920.
