266 EXTOMOLOGiCAL NEWS [June, 'll 



Co., Arizona, in the Collection Barnes, and have found a sin- 

 gle specimen among them in which veins 4 and 5 of the fore 

 wing are distinctly separate, although very shortly so just as 

 Dr. Dyar states is the case with the type of tener. The re- 

 maining specimens fall in about equal numbers into two 

 groups, having veins 4-5 either stalked or from a point. In 

 one case there was an extra vein between veins 3 and 4. The 

 specimen with veins separate differs in no respect from the 

 others, and all agree exactly both with the description and 

 the figure given in the Biol. Cent. Amer. Dr. Dyar's descrip- 

 tion of achriogelos would also apply equally well to tener. 



With regard to the hind wings of the specimens before us, 

 most of them have veins 3-4 from a point (connate.) Sev- 

 eral specimens however show these veins very distinctly but 

 shortly separate. As the genera Mesoscia and Ratnaca are 

 separated by Dyar on the strength of veins 3-4 of hind wings 

 being separate or connate, it is rather doubtful whether Ra- 

 maca Dyar will hold. As however we have no South Ameri- 

 can material before us, we leave this point to be decided by 

 more competent authorities than ourselves. 



To return to tener, we consider then that achriogelos Dyar 

 is an absolute synonym, the slight difference in venation in 

 the type of tener being due to mere accidental variation. As 

 to the genus into which this species should be placed we are 

 rather at a loss to decide. Dr. Dyar has removed it from 

 Archylus and placed it in Norape; it cannot remain there, 

 however, as veins 4 and 5 of fore wing are more often con- 

 nate or stalked than separate ; it is shut out from Ramaca 

 owing to the fact that veins 3-4 of hing wings are sometimes 

 separate, which would place it in the genus Mesoscia. It 

 seems to vacillate between these two last named genera and 

 has become an outcast and a wanderer, surely a harsh fate 

 for such a delicate species. Let us hope it will find a firm 

 abiding place without the necessity of creating still another 

 new genus.
