Sept.-Dec, 1920.] FORBES : NoTES ON THE CrAMBIX.E. 215 



fused witli R. in Raphiptcra and the new j^cnus Loxocramhus; third 

 A rudimentary as a rule, free. Hind wing with Sc and R anastomo- 

 sing, with a strong fringe on base of Cu and three developed anals, 

 in other characters of two principal types: (i) (Crambini) with 

 frenulum multii)le in female, cell widely open, the discocellular being 

 reduced to a short spur attached to Cu stem, and M, approximate or 

 stalked with Rji ; (2) (Ancylolomiini ) with frenulum simple in female, 

 cell closed by a distinct though somewhat weak vein, and M, widely 

 separated from distal part of R^ at its origin from cell, and often 

 somewhat weak. The tip of Sc is lost in the Crambine genus 

 Raphiptcra. 



I should reject the two genera Chalco'cla and Dicymolomia from 

 this group ; their affinities are wholly with the genus Glapliyria and 

 its kin, usually considered PyraustinJE, but possibly worthy of a 

 separate subfamily, based mainly on the character of the fringe on 

 the base of Cu, which runs out diffusely into the outer part of the 

 wing, diverging from Cu, and ends in a more or less striking tuft 

 of spatulate scales. This group would be the Homophysida^ of 

 Guenee. etc. The Schoenobiin?e I should separate primarily on the 

 preservation of first A toward the margin of the fore wing, as this 

 is a significant primitive character occurring in no other group of 

 Pyralids known to me, and present in all Schoenobiinse examined, 

 even the strongly aberrant genus Accntropus. The fringe of hair 

 on cubitus is in its weakest expression in the Crambinre about like its 

 fullest development in the Schoenobiinae. I believe that Loxostc- 

 gopsis^ which lacks first A is not a Schoenobiid, but an aberrant 

 Pyraustid. The Phycitinse and Anerastiinse. aside from their con- 

 sistent loss of a radial, combine characters of the two tribes of Cram- 

 binae. From the Ancylolomiini they differ in having R and Mj of 

 the hind wing approximate, from the Crambini in the more distinctly 

 closed cell, and simple female frenulum. Very few have the large 

 triangular maxillary palpi common to both groups of Crambina'. I 

 have omitted Uscodys from the following key, as probably Schoeno- 

 l>iid, since first A is preserved. Sc and R are separate in the hind 

 wing, a very rare character in either grouj). 1 have noted from the 

 type of Uinta orcadclhi Hulst, that R of the hind wing is from the 



1 I consider " Loxotcgopsis " an obvious misprint.
