Regarding Diapheromera veliei Walsh and Manomera 

 blatchleyi Caudell (Orth. : Phasmidae). 



By A. N. Caudell, of the Bureau of Entomology, U. S. 

 Department of Agriculture. Washington. D. C. 



The type material of Diapheromera rcUei Walsh consisted 

 of one female specimen from Illinois, taken in a place over- 

 grown by weeds beneath the boughs of two isolated ash trees, 

 and one pair from Nebraska taken by Dr. \'elie in a place 

 overgrown by weeds but with no trees within a long distance 

 of it. The description drawn from these three specimens ap- 

 pears to apply to Manomera blatchleyi so far as concerns the 

 female, but the characters ascribed to the male apply to the 

 true veliei. The slender acute basal spine of the cerci of the 

 male described by \\'alsh certainly pertain to veliei rather than 

 to blatehleyi and. besides, if it had been the male of hlatehlcyi 

 Walsh had before him he would very surely have mentioned 

 the but slightly swollen intermediate femora as a character 

 decidedly at variance with those of D. fcmorata, the species 

 with which he compared this new species. That he did specifi- 

 cally notice the middle femora is evident from the fact that 

 he mentions their lacking the brown banding of femorata. 

 Thus it appears very certain that, while the female from Illi- 

 nois was quite surely a specimen of ilf. blatchleyi, the male 

 from Nebraska, probably also the Nebraska female, was the 

 true veliei. That the male is to be rightly considered as the 

 specific type is evident from the fact that the male is morpho- 

 logically the more important in this group and that this con- 

 struction is according to good sense and in compliance with 

 Par. 73/1 of the Entomological Code of Nomenclature. 



Diapheromera veliei may be distinguished from Mano)nera 

 blatchleyi by the comparatively shorter and anteriorly broader 

 head of both sexes, by the strongly swollen intermediate fem- 

 ora of the male and by the posterior femora of both male and 

 female being furnished beneath with a prominent subapical 

 spine, in Manomera this spine being either entirelv absent or 

 verv small. The last dorsal segment of the abdomen of the
