The coloration of this species is strikingly similar to that of Gruci- 

 laria elongella Linnteus, var. alnicoleUa Chambers/' The fore wings 

 of this and the following species have veins 6 and 7 stalked, one branch 

 going to each side of apex; in those European species of Zelleria^ 

 which I have been able to examine, these two veins are separate 

 though approximate at base; such is also the case with an American 

 species^' on Celastrus, which I have determined for Mr. William 

 Kearfott; but as all the other characters are tj^pical I do not think 

 this difference of generic value. Meyrick places this genus and Argy- 

 resthia in the Tineidas, but in spite of the tufted head they seem to 

 me more nearly related to the Yponomeutidse., as placed by Staudinger 

 and Rebel.'' The old family, x\.rgyredhiidse,^ should probably be 

 adopted. 



ZELLERIA RIBESELLA, new species. 



Labial palpi yellow, strongly mottled with ])lack especially on the 

 outer and under surface. Antennae blackish. Face whitish. Tuft 

 on head light greenish yellow. Thorax and fore wings light greenish 

 yellow with sparse black scales irregularly scattered over the wing 

 and congregating more densely into a longitudinal interrupted streak, 

 under and parallel with the fold and into another longitudinal streak 

 before apex; basal half of costal edge is also black. The black is 

 really the ground color of the wing, but it is so closely overlaid with 

 the light scales as to make the wing decidedly light colored. Cilia 

 dark fuscous. Hind wings dark fuscous. Abdomen blackish, sprinkled 

 on the underside with yellow. Legs dark fuscous, sprinkled on the 

 outer surfaces with ^^ellow. 



Alar expanse: 19 mm.

Foodplant: R!hes lacush'e. 



Type.— Cat No. 7814, U. S. National Museum. 



Bred l)y Doctor Dyar at the same time and from the same foodplant 

 as the foregoing species without differences in larva3 being noted. 

 This would suggest that this species might be only a variety of the 

 foregoing and such may ultimately l)e. proven, l)ut in the absence of 

 actual observation, the very different coloration does not permit such 

 assumption. 



This species has a noteworthy superficial resemblance to Graeilaria 

 elongella Linnseus, var. shastaella Beutenmiiller.'^
