 In none of these males does the yellow of the front wings extend con- 

 tinuously to the nodus where each, however, has a small yellow cloud ; 

 the blackish basal streak in the subcostal space of the hind wings 

 reaches to the level of the arculus in those of October 22 and November 

 24 ; in the other two and in the two females it stops at the first anteno- 

 dal or but slightly distad. The female of October 31 has the basal yel- 

 low confined to a very narrow border around the blackish basal streaks 

 and a mere trace of yellow at the nodus, in that of November i the 

 yellow in the subcostal space fades out just beyond the level of the 

 triangle, but the nodal cloud is distinct.

Remarks on the Species assigned to Cavotettix Han- 

 cock, a Synonym of Neotettix Hancock (Orthop- 

 tera, Acrididae, Acrydiinae.) 



By MORGAN HEBARD, Philadelphia, Pa. 



In the month of November, 1918, there appeared a paper 

 by Dr. J. L. Hancock in the ENTOMOLOGICAL NEWS, in which a 

 new genus and two new species were described. As one of the 

 species described by Rehn and Hebard in 1916, as a member 

 of the genus Ncotetti.r, was assigned to this new genus, the 

 author's interest was at once aroused as to the reason for such 

 generic reassignment. 



In order to weigh carefully the features in the problem to 

 be considered, the very large series of Ncotetti.r feiiwratns 

 (Scudder) and Ncotetti.r boltcri Hancock, in the Philadelphia 

 collections, have been examined and compared with the mater- 

 ial at hand referable to the species assigned to Coi'otetti.r by 

 Hancock. From these studies we are satisfied that Cavotettix 

 Hancock must fall as a synonym of Ncotetti.r Hancock. 



Taking Hancock's description of Cat'otctti.r, we find that 

 the majority of the features, given as diagnostic for that genus, 

 are those resultant from the retention of an immature pronotal
